Detailed ways

For the description of the background technology part, in the 3D video application based on the naked-eye 3D (three-dimensional) technology, in order to prevent the dizziness caused by the 3D video, the binocular view of the 3D video (that is, the left-eye disparity map and the right-eye disparity map, can also be The parallax of the left-eye image and the right-eye image) can be controlled in a small range, but the 3D effect is reduced, and the 3D effects obtained by different viewing angles and viewing distances will also be different. This application hopes to avoid dizziness caused by viewers watching 3D videos with naked eyes on the basis of ensuring the 3D effect as soon as possible, and alleviate the actual focus plane and perception of the 3D objects watched (such as at least one object in the 3D video displayed on the display screen). Frequent switching between focus planes can easily cause visual fatigue, improving the user's naked-eye 3D video viewing experience.

Based on this, the present application proposes to monitor the change value of the physiological information of the viewer that can characterize the vertigo degree of the viewer watching the 3D object, so as to accurately obtain the parallax adjustment of the 3D object in the binocular view of the current viewer according to the change value of the physiological information Value, after that, combined with three-dimensional display technology (ie, stereo vision technology), according to the parallax adjustment value, the image data of the 3D object output by the display screen can be automatically updated in time, thereby changing the 3D display effect of the display screen in time, so that it can output 3D objects The parallax is within the comfortable parallax range of the current viewer, avoiding dizziness when viewing 3D objects with naked eyes, prolonging the time for viewing 3D content with naked eyes, and helping to promote naked-eye 3D technology products. At the same time, it also prevents the compression of the parallax range from being too small to weaken the 3D effect and reduce the immersive experience of the viewer.

The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

Referring to FIG. 1 , it is a schematic flowchart of an optional embodiment 1 of the naked-eye 3D image processing method proposed in this application. This method can be applied to image processing devices, such as image processors or other electronic devices with image processing capabilities, etc., which can be based on Naked-eye 3D image viewing scene requirements are determined. In practical applications, on the basis of ensuring the naked-eye 3D viewing effect, prevent or solve the dizziness of the viewer watching the 3D image with the naked eye, as shown in Figure 1, this embodiment proposes the following naked-eye 3D image processing method:

Step S11, obtaining the physiological information of the viewer in front of the display screen; the physiological information can represent the vertigo degree of the viewer watching the 3D object output by the display screen;

When the viewer is in front of the display screen and watches the 3D video or pictures output by the display screen with naked eyes, the distance between the left and right eyes is the interpupillary distance, so that the images entering the left and right eyes (that is, the image for the left eye and the image for the right eye) There is a certain parallax between them, which will induce the brain's eyes to focus on 3D objects at different distances, thereby producing a stereoscopic sense with depth of field, that is, stereoscopic vision. However, because the perceived focus screen where the eyes focus on the perceived 3D object position is different from the actual focus screen that is actually focused on the display screen, as the viewing time increases, the physiological information that the viewer has that can characterize the degree of vertigo will occur. Variety.

Based on this, in order to solve the problem from the source of the viewer's dizziness, make the presentation of the stereo effect of the 3D data source more in line with the physiological characteristics of the human eye, reduce the burden on the viewer's eyes, and let the viewer experience the The best visual effects. This application can obtain the physiological information of the viewer in real time or according to preset rules during the process of watching the 3D content output by the display screen with naked eyes, such as one of the blink frequency, blink duration, line of sight beating frequency and emotional information, etc. or multiple combinations, the type of physiological information obtained can be determined according to the situation.

It should be understood that different types of physiological information can be obtained in different ways, for example, the viewer's face image or eye image can be obtained, and the current blink frequency, blink duration and/or line of sight of the viewer can be obtained through the analysis of multiple consecutive frames of images Physiological information such as beating frequency; for physiological information that cannot be obtained through image analysis, it can be obtained through corresponding types of acquisition equipment, and the implementation process will not be described in detail in this application.

In addition, it needs to be explained that, regarding the degree of vertigo of the viewer watching the 3D object, generally, the lower the degree of vertigo means that the viewer is more comfortable viewing the 3D object, but the degree of vertigo does not mean that the viewer is in a state of vertigo, but rather When the degree of vertigo reaches a certain value, it may be indicated that the viewer is in a state of vertigo.

Step S12, determining the change value of the physiological information;

Step S13, according to the change value of the physiological information, obtain the parallax adjustment value of the 3D object in the viewer's binocular view;

Combined with the above description of the physiological information of the naked-eye 3D object viewer, the disparity of the viewer's binocular view (ie, the left-eye disparity map and the right-eye disparity map, which can also be called the left-eye image and the right-eye image) is different In the case of a 3D object, whether the viewer will feel dizzy when viewing the 3D object with naked eyes, and the degree of dizziness after the dizziness will be different. It can be seen that the change of the parallax of the binocular view is related to the change of the physiological information of the viewer watching the corresponding 3D object (that is, whether the viewer is dizzy, and the change of the degree of vertigo) has a certain relationship, and the present application does not limit the content of the relationship and its representation.

Based on this, in order to understand the changes in the degree of dizziness of the current viewer viewing the 3D object output by the display screen with naked eyes, and determine whether it is necessary to adjust the parallax between the binocular views (that is, the parallax map for the left eye and the parallax map for the right eye), the application can be based on the physiological The preset monitoring rules of the information determine the change value of the physiological information (the positive and negative values of the value indicate the direction of increase or decrease of the physiological information, and the numerical value indicates the change amount of the physiological information), and then, according to the change value , timely and accurately obtain the parallax adjustment value of the 3D object in the viewer's binocular view (the positive and negative values of the value represent the adjustment direction of increasing or decreasing the parallax of the 3D object, and the value represents the parallax adjustment amount of the 3D object) For example, to adjust the parallax adjustment direction of the binocular view so that the viewer's viewing experience of the 3D object is not dizzy, the specific parallax adjustment value can be determined according to the above-mentioned association relationship, which is not described in detail in this embodiment.

It should be noted that, with regard to the content of the change value of the above physiological information or the method for obtaining it, the relationship between the change value and the parallax adjustment value of the binocular view may be different. The association relationship can be determined through a large number of experiments or experience or training and learning, and this application does not limit the method for obtaining the association relationship.

Wherein, the change value of the above-mentioned physiological information may be a combination of the currently obtained physiological information of the viewer and its historical physiological information or the initial physiological information collected when watching a 3D video, or the first physiological threshold used to determine whether it is in a state of vertigo, or The second physiological thresholds of different vertigo levels are compared and obtained. The implementation process can refer to but is not limited to the description of the corresponding part of the detailed embodiment below, and this embodiment will not be described in detail here.

Step S14 , updating the image data of the 3D object output by the display screen according to the parallax adjustment value.

Following the above analysis, in order to prevent the current viewer from feeling dizzy when watching the 3D object output by the display screen with naked eyes, the change value of the physiological information of the viewer is used to determine that the parallax of the binocular view of the currently output 3D object will cause the viewer to watch with naked eyes. , or even dizziness, the parallax of the binocular view needs to be adjusted in time. Specifically, the parallax adjustment value of the binocular view will be accurately determined according to the change value of the viewer's actual physiological information, and the image data of the binocular view will be updated accordingly. , to compress the virtual depth of field range of the 3D object to a smaller range before and after the display screen, as shown in Figure 2, so that the perceived focus plane (that is, the virtual focus plane) of the viewer viewing the 3D object with naked eyes is closer to the actual focus plane, reducing Vertigo in the viewer.

It should be noted that in practical applications, the viewer has a stronger sense of vertigo when watching 3D objects with naked eyes, and the larger parallax adjustment value corresponding to the binocular view and the compression to a smaller virtual depth of field range are used to relieve the viewer from viewing 3D objects with naked eyes. Vertigo, this application does not limit the content of the corresponding relationship between the three and the way of expression, it depends on the situation.

In addition, this application does not limit the implementation method of adjusting the parallax of the binocular view of the 3D data source and generating 3D image data with adjusted parallax to achieve a new 3D effect. Technical implementation, this application does not describe the generation process of 3D image data in detail.

In summary, in the embodiment of the present application, during the process of viewing the 3D video output by the display screen with the naked eyes of the viewer, the physiological information currently possessed by the viewer that can represent the degree of vertigo can be obtained, and after determining the change value of the physiological information, According to the change value of the physiological information, the parallax adjustment value of the 3D object in the viewer's binocular view is obtained in a timely and accurate manner. Usually, the parallax adjustment value of the 3D object that is far away in the binocular view is small, so that it has an adjusted The parallax is relatively large. According to the parallax adjustment amount, the image data of the 3D object output by the display screen is updated in time. While ensuring the 3D effect as much as possible, reduce or solve the problem caused by the actual interpupillary distance of the viewer, the viewer and the display screen. At least one factor such as the viewing distance and/or viewing angle, viewing parallax, etc. is inappropriate, which will cause the viewer to feel dizzy when watching the 3D video with naked eyes, and improve the immersive experience.

Referring to FIG. 3, it is a schematic flowchart of an optional embodiment 2 of the naked-eye 3D image processing method proposed in this application. This method can still be applied to an image processing device. As shown in FIG. 3, the method may include:

Step S31, obtaining the spatial position information of the eyes of the viewer in front of the display screen relative to the display screen, and the interpupillary distance of the viewer;

The default parallax of the binocular view of 3D video can be calculated by counting the actual interpupillary distance of a large number of users and different viewing distances. It is within the parallax range that most users can comfortably watch 3D video, but this often cannot accurately balance the 3D effect and The binocular parallax comfort value of each viewer, so this application proposes to dynamically obtain the initial parallax of the naked-eye 3D video for the viewer in front of the display screen, and then process the 3D video to generate a 3D object with the initial parallax The image data is sent to the display screen for output, so that the viewer can comfortably watch the 3D video on the basis of ensuring the 3D effect of the 3D video to the greatest extent.

Based on this, after analysis, it can be known that the viewer's actual interpupillary distance and its viewing distance, viewing angle and other parameters will often affect the experience of watching 3D videos with naked eyes, and even cause the viewer to feel dizzy. , dynamically configure the initial disparity of the 3D video to avoid discomfort for the user when watching the 3D video. Specifically, when it is determined that there is a viewer in front of the display screen, the interpupillary distance of the viewer and the spatial position information of the viewer's eyes relative to the display screen can be obtained, such as the distance between the left and right eyes of the viewer and the display screen. The distance between them, and the angle formed by the intersection of the line of sight of the left and right eyes and the display screen, etc., the present application does not limit the content of the spatial location information and its representation.

In some embodiments, the face image or eye image of the viewer can be collected, and the collected image can be analyzed through image recognition technology to obtain the interpupillary distance of the viewer and the spatial position of the left and right eyes. In the case of an image display device, the spatial position may refer to spatial coordinates in the camera coordinate system, etc. At this time, the spatial coordinates may be used to determine the spatial position information of the eyes relative to the display screen.

If the camera is used as an independent image acquisition device and is not integrated or installed on the image display device, the spatial position of the viewer's left and right eyes can refer to the spatial coordinates in the world coordinate system. At this time, the display screen in the world coordinate system can be obtained The spatial coordinates of the two eyes are compared with the spatial coordinates of the display screen to obtain the spatial position information of the two eyes relative to the display screen. Optionally, the spatial positions of the left and right eyes in this embodiment can also be spatial coordinates in the camera coordinate system, which need to be converted into spatial coordinates in the world coordinate system, combined with the spatial coordinates of the display screen in the world coordinate system to determine the relative Regarding the spatial position information of the display screen, the implementation process is not described in detail in this application.

It should be noted that the method for obtaining the spatial position information of the viewer's eyes relative to the display screen includes but is not limited to the image recognition implementation method described above, and the viewing parameters can also be obtained through the parameters sensed by other sensing devices as needed. The interpupillary distance of the user and the spatial position of the left and right eyes, and then obtain the spatial position information of the left and right eyes relative to the display screen. The implementation process will not be described in detail in this application.

Step S32, according to the spatial position information and the interpupillary distance, obtain the initial parallax of the viewer's binocular view;

Step S33, controlling the display screen to output the image data of the 3D object according to the initial parallax;

Following the above analysis, using the interpupillary distance of the viewer and the convergence formed by the spatial position information of the left and right eyes with respect to the display screen (such as the angle formed by the intersection of the left and right eye sight lines with the display screen), the 3D objects viewed by the viewer's naked eyes are obtained. The initial disparity of the binocular view of , which is used to determine the initial 3D effect of the 3D data source.

In practical applications, the farther the viewing distance between the left and right eyes of the viewer and the display screen, the greater the parallax of the binocular view that ensures that the viewer does not feel dizzy when watching 3D videos; The greater the parallax of the binocular view, the less dizzy the 3D video is. Based on this, the application can predetermine the corresponding relationship between different interpupillary distances and different spatial position information, and different parallax of binocular views (such as a corresponding relationship table or a relationship model, etc., the expression method of this application and its acquisition method not limited), so that according to the corresponding relationship, obtain the binocular view parallax corresponding to the current viewer's interpupillary distance and the spatial position information of the left and right eyes relative to the display screen, and determine it as the initial view of the binocular parallax for the viewer , that is, to determine the disparity of the display screen to start outputting 3D video.

Afterwards, a binocular view with the initial parallax can be generated according to the determined initial parallax, and image data of the 3D object with the initial parallax of the binocular view can be obtained through processing such as image synthesis and rendering, and sent to the display screen for display. This application does not describe in detail how to obtain the image data of the 3D object according to the initial parallax, and it can be implemented in combination with naked-eye 3D display technology.

Step S34, obtaining the physiological information of the viewer; the physiological information can represent the vertigo degree of the viewer viewing the 3D object output by the display screen;

Step S35, determining the change value of the physiological information;

Step S36, acquiring a third correlation between different change values of physiological information and different parallax adjustment values;

Step S37, according to the third correlation and the change value of the physiological information, obtain the parallax adjustment value of the 3D object in the binocular view of the viewer;

Step S38 , updating the image data of the 3D object output by the display screen according to the parallax adjustment value.

As analyzed above, for the 3D video output by the display screen, the parallax of the view of the two eyes is set according to the actual interpupillary distance of the current viewer and the spatial position information of the left and right eyes relative to the display screen, so as to ensure that it starts to output the 3D video. At the same time as the 3D effect, the viewer will not feel dizzy when starting to watch the 3D video.

Afterwards, as the viewing time of each 3D object included in the 3D video increases with the viewer's naked eyes, and the virtual depth of field of different 3D objects output by the display screen at different times is different, the viewer may experience dizziness. Naked-eye 3D experience, as described in the corresponding part of the above embodiment, the application can dynamically adjust the parallax of 3D objects in the binocular view according to the change value of the viewer's physiological information, so as to prevent or reduce the dizziness of naked-eye 3D display viewing.

In the practical application of this embodiment, it is possible to analyze the relationship between the change values of different types of physiological information of the viewer and the different parallaxes of the binocular view through experiments with a large amount of data, and to obtain different types of The relationship between the different change values of the physiological information and the different parallax adjustment values (in order to distinguish it from other relationships in this application, it is recorded as the third relationship here), store the relationship for subsequent playback of 3D video query in process.

Wherein, the above-mentioned third association relationship may be obtained by the image processing device before watching the 3D video, or obtained by analyzing the server corresponding to the server, and the image processing device obtains the different change values and different parallax adjustments of the required types of physiological information from the server. The third association relationship between values, etc., this application does not limit the execution subject that obtains the third association relationship.

In addition, since the physiological information of the viewer and the parallax of the binocular view change continuously, the above-mentioned third correlation can be represented by a linear model, so that each time the detected physiological information changes, the binocular view can be determined accordingly. The new parallax, based on which the image data of the 3D object to be output is updated or generated, and the 3D effect is dynamically adjusted; of course, the third association relationship can also be expressed by a relationship table or expressed in other ways, and the relationship table is usually queried to determine the relationship with The parallax adjustment value corresponding to the change value of the currently obtained physiological information.

Optionally, for the third association relationship such as the relationship table, the change value of physiological information may also be a change range value, and the change value of physiological information belonging to the same range may correspond to the parallax adjustment value of the same binocular view. In this way, in In practical applications, the change range of the type of physiological information to which the change value of the currently obtained physiological information belongs can be determined, and the parallax adjustment value corresponding to the change range can be determined as the parallax adjustment value for the binocular view of the current viewer.

It should be understood that, when the binocular disparity is dynamically adjusted for the first time, it may be the parallax adjustment value for the initial parallax determined above; It may be the parallax adjustment value for the initial parallax, which may be determined according to the configuration of the parallax adjustment values for binocular views in the third association relationship, which is not limited in the present application.

In addition, this time, according to the parallax adjustment value, the image data of the 3D object output by the display screen is updated, or the image data of the 3D object to be output is generated, and sent to the display to output the 3D object with the adjusted parallax. During this period and after the output, Step S34 and its subsequent steps can still be performed to continuously obtain the change value of the viewer's physiological information, so as to realize the dynamic adjustment of the parallax of the binocular view of the 3D video. The implementation process is similar and will not be described in this application.

Referring to FIG. 4 , it is a schematic flowchart of an optional third embodiment of the naked-eye 3D image processing method proposed in this application. This embodiment can describe an optional detailed implementation method of the above-mentioned naked-eye 3D image processing method, as shown in FIG. 4, the method may include:

Step S41, obtaining the physiological information of the viewer in front of the display screen; the physiological information can represent the vertigo degree of the viewer watching the 3D object output by the display screen;

It should be understood that the present application can obtain the image data of the 3D video according to the default fixed parallax, or the initial parallax determined for the viewer (the acquisition process can refer to the description of the corresponding part of the above embodiment), etc., and send it to the display screen The output is performed, and the implementation process is not described in detail in this embodiment. Physiological information of the viewer can be obtained from the time the viewer watches the display screen or the 3D object output by the viewer.

Step S42, obtaining a first physiological threshold for determining whether the viewer is in a state of vertigo;

Step S43, determining a first change value between the currently obtained physiological information and the first physiological threshold;

In the embodiment of the present application, the first physiological threshold may be a pre-configured fixed threshold, which may be determined through a large amount of data experiments or experience, and the present application does not limit its value, and for different types of physiological information, its corresponding first A physiological threshold can be different. Based on this, in this embodiment, the currently obtained physiological information is compared with a first physiological threshold of the same type to determine a first change value.

It can be seen that the first change value can indicate whether the physiological information of the current viewer is greater than the first physiological threshold, and the difference between the physiological information exceeds the first physiological threshold. If the physiological information is greater than the first physiological threshold, it can be considered that the currently viewing If the viewer is currently in a dizzy state; otherwise, it can be considered that the current viewer is not in a dizzy state, and the physiological information of the viewer can be continuously obtained according to the above method without adjusting the parallax of the 3D object in the binocular view.

Step S44, according to the first change value, obtain a parallax adjustment value for the 3D object in the viewer's binocular view;

Step S45 , updating the image data of the 3D object output by the display screen according to the parallax adjustment value.

Following the above analysis, when it is determined that the current viewer is in a dizzy state, according to the description in the corresponding part of the above embodiment, and according to the currently obtained first change value, determine the direction and amount of parallax adjustment for the binocular view, that is, the parallax adjustment value , so as to update the image data of the 3D object accordingly, and adjust the 3D effect output by the display screen.

Wherein, regarding the implementation process of step S44, you can refer to the description of the corresponding part of the above embodiment. The larger the absolute value of the first change value is, the larger the parallax adjustment value of the 3D object in the obtained binocular view is usually, and the same binocular view The parallax adjustment values of 3D objects at different distances can be different. For example, the absolute value of the parallax adjustment value of the 3D object with a larger distance in the binocular view can also be smaller. Regarding the relationship between the first change value and the parallax adjustment value , can be represented by a linear model, a relational table, or a machine learning model. This application does not describe the implementation process of step S44 in detail.

Referring to FIG. 5 , it is a schematic flowchart of the fourth optional embodiment of the naked-eye 3D image processing method proposed in this application. This embodiment can describe another optional detailed implementation method of the above-mentioned naked-eye 3D image processing method, as As shown in Figure 5, the method may include:

Step S51, obtaining the physiological information of the viewer in front of the display screen; the physiological information can represent the vertigo degree of the viewer viewing the 3D object output by the display screen;

Step S52, obtaining second physiological thresholds corresponding to different vertigo levels;

Step S53, determining a second change value between the currently obtained physiological information and the second physiological threshold;

Step S54, according to the second change value, determine the current level of the viewer in the dizzy state; different dizziness levels correspond to different dizziness degrees of the viewer watching the 3D object;

In the embodiment of the present application, when the viewer feels dizzy or finds it difficult to focus on naked-eye 3D objects, his physiological information will change abruptly, such as a physiological reaction of a sharp increase in the blinking frequency and a jump in the line of sight. The greater the degree of dizziness of the viewer, The amount of change in physiological information tends to be larger. Based on this, the present application can divide the vertigo produced by the viewer into multiple vertigo levels according to the degree of vertigo of the viewer (which can be determined according to the value of physiological information), and obtain the range of physiological information corresponding to each of the different vertigo levels , determine the boundary value within the variation range of the physiological information as the second physiological threshold corresponding to the vertigo level, which is used to distinguish different vertigo levels. Restrictions, subject to availability.

As analyzed above, if the vertigo level is higher, it means that the viewer has a stronger sense of vertigo, and the corresponding second physiological threshold can often be larger. In this way, after obtaining the current physiological information of the viewer, it can be compared with each second physiological threshold. The threshold is compared to determine that the physiological information falls within the physiological information change range of the vertigo level, and the vertigo level is determined as the vertigo level of the current viewer. Among them, if the vertigo level is 0 or a lower level (the number of vertigo levels can be set in advance), it can be considered that the viewer does not have a sense of vertigo, and the current naked-eye 3D display effect can be maintained, and the physiological information of the viewer can be continuously detected and analyzed .

It can be seen that the above-mentioned second change value may be the difference between the currently obtained physiological information and the second physiological threshold corresponding to the level of vertigo, and it is determined that the second change value between the current physiological information and the second physiological threshold of a certain level of vertigo is greater than zero , and the second physiological threshold of the physiological information and its adjacent vertigo level is less than or equal to zero, it can be determined that the physiological information is within the variation range of the physiological information of the certain vertigo level, and the certain vertigo level is the current vertigo level of the viewer. It should be noted that the method for obtaining the current vertigo level of the viewer includes but is not limited to the method described in this embodiment, and this application does not give examples and details one by one.

In some embodiments, for the second physiological thresholds corresponding to different dizziness levels, the thresholds can be fixed, or the fixed thresholds can be optimized and adjusted in combination with the initial physiological information of the current viewer to obtain the corresponding dizziness levels of the current viewer. The second physiological threshold to improve the accuracy of parallax adjustment for subsequent binocular views. Therefore, the above step S53 may include but is not limited to the implementation method described in the following paragraph:

Obtain the third physiological threshold (which may be equal to the first physiological threshold) for determining whether different viewers are in a dizzy state, and the fourth physiological threshold (such as the above-mentioned fixed threshold) corresponding to different dizziness levels of different viewers at the same time, in Read the initial physiological information of the current viewer, perform a ratio calculation with the third physiological threshold, and determine the fifth change value between the initial physiological information of the viewer and the third physiological threshold, so that according to the fifth change value and the first Four physiological thresholds, to obtain the second physiological thresholds corresponding to different dizziness levels of the viewer, if the fifth change value is determined as the optimal adjustment coefficient, the optimal adjustment coefficient is multiplied by the fourth physiological thresholds of each dizziness level to obtain The second physiological threshold corresponding to the level of vertigo.

Step S55, obtaining the parallax adjustment value of the 3D object in the viewer's binocular view according to the current vertigo level;

Step S56 , updating the image data of the 3D object output by the display screen according to the parallax adjustment value.

In practical applications, the present application can pre-determine the parallax adjustment value or preset parallax that can make the viewer watch the 3D object with naked eyes without vertigo for different vertigo levels. After the new vertigo level is determined, the parallax adjustment value for the viewer's binocular view can be obtained in a timely and accurate manner based on this, and then the image data of the 3D object can be updated or generated, and the 3D effect of the output 3D object can be adjusted to avoid viewing suffer from dizziness.

Based on the above analysis, after determining the current vertigo level at which the viewer watches the 3D object with naked eyes, the first correlation between different vertigo levels and different preset parallaxes (ie, binocular view parallaxes) can be obtained. In practical applications, the preset parallax corresponding to different vertigo levels can be a fixed parallax, which can be determined through a large number of experiments or based on experience; in order to improve the accuracy of parallax adjustment, the application can also be based on the initial parallax of the viewer (the acquisition method can be Referring to the description of the corresponding part of the above embodiment), determine the preset parallax corresponding to different vertigo levels, such as according to the preset parallax step size, starting from the initial parallax, each time a vertigo level is increased, the preset parallax of the previous vertigo level can be Add one or more parallax steps on the basis of the parallax to obtain the preset parallax of the vertigo level, and then determine the preset parallax corresponding to different vertigo levels step by step.

In some other embodiments, the present application may also determine the preset parallax corresponding to different vertigo levels according to the fifth change value between the viewer's initial physiological information and the third physiological threshold and the fixed parallax. In combination with the relevant description of the fifth variation above, it can be used as a parallax adjustment coefficient to perform a product operation with fixed parallax corresponding to different vertigo levels one-to-one to obtain a preset parallax corresponding to the vertigo level. It can be seen that this method of obtaining the preset disparity fully considers the actual initial physiological information of the current viewer, so that the obtained preset disparity is more compatible with the current viewer's comfortable viewing of naked-eye 3D objects, which helps to improve the 3D effect. Wherein, the third physiological threshold is used to determine whether different viewers are in a state of vertigo, and may be the same as or different from the above-mentioned first physiological threshold, which depends on how the first physiological threshold is determined.

After that, the above-mentioned first correlation can be used to determine the adjustment value of the preset parallax between the current vertigo level and the adjacent vertigo level; the vertigo degree of the viewer corresponding to the adjacent vertigo level is smaller than the vertigo degree of the viewer corresponding to the current vertigo level , that is to say, when the viewer is in a state of vertigo, the current vertigo level of the viewer can be adjusted downward by one or more vertigo levels (one adjustment in this application can reduce multiple consecutive vertigo levels, or each time Adjust a vertigo level, which can be determined according to the size of the change value of the currently obtained physiological information, and this application does not limit it), and obtain the parallax adjustment value between it and the current vertigo level, that is, the predicted value corresponding to the two vertigo levels. The difference between the parallaxes is set, so as to use the determined adjustment value to obtain the parallax adjustment value of the 3D object in the binocular view.

In some other embodiments proposed by the present application, different from the method for obtaining the parallax adjustment value described above, the present application may also predetermine the second correlation between different dizziness levels and different preset parallax adjustment values. The method of obtaining the preset parallax adjustment value is similar to the method of obtaining the preset parallax of different vertigo levels described above. Each preset parallax adjustment value can be a fixed adjustment value, or it can be based on the initial parallax or physiological information of the viewer To determine the preset parallax adjustment value corresponding to the vertigo level, for example, the ratio between the current physiological information of the viewer and the initial physiological information is determined as the parallax adjustment coefficient, and the fixed parallax adjustment value corresponding to each vertigo level product to obtain the preset parallax adjustment value corresponding to the vertigo level; similarly, the parallax adjustment coefficient can be determined based on the ratio of the current binocular view parallax to the initial parallax, and the fixed parallax adjustment value corresponding to each vertigo level can be personalized and optimized. The preset parallax adjustment value corresponding to the vertigo level and the like are obtained, but is not limited to the implementation method described in this embodiment.

After that, the second association relationship can be used to determine the preset parallax adjustment value associated with the current vertigo level, such as querying the second association relationship, the preset parallax adjustment value corresponding to the current vertigo level, so as to use the determined value to obtain the parallax adjustment value of the 3D object in the viewer's binocular view. If the preset parallax adjustment value is directly determined as the parallax adjustment value of the 3D object in the binocular view, the preset parallax adjustment value can also be set according to the preset rules. After the adjustment value is adaptively processed, the preset parallax adjustment value obtained from the processing is determined as the parallax adjustment value of the 3D object in the binocular view, etc. The implementation process is not described in detail in this application.

Referring to FIG. 6 , it is a schematic flowchart of an optional embodiment five of the naked-eye 3D image processing method proposed in this application. This embodiment can describe another optional detailed implementation method of the above-mentioned naked-eye 3D image processing method, as shown in As shown in Figure 6, the method may include:

Step S61, obtaining the physiological information of the viewer in front of the display screen; the physiological information can represent the vertigo degree of the viewer viewing the 3D object output by the display screen;

Step S62, obtaining the initial physiological information of the viewer;

Step S63, determining a third change value between the currently obtained physiological information and the initial physiological information;

Step S64, according to the third change value, obtain the parallax adjustment value of the 3D object in the viewer's binocular view;

Combined with the relevant description of the initial physiological information above, when the viewer starts to watch the naked-eye 3D object, the viewer will often not be dizzy, and the physiological information such as the blinking frequency and the beating frequency of the line of sight are basically the same as the daily physiological information of the viewer. The viewer is in a comfortable state to watch the naked-eye 3D object. Therefore, the application can use the viewer's initial physiological information as the basis for the change of physiological information, and obtain the change rate of the viewer's actual physiological information relative to its initial physiological information in time, which is determined as The third change value above.

It can be seen that in the scene where different viewers watch the same 3D object output by the same display screen with naked eyes, the initial physiological information of each viewer may be different. It may be different, and the parallax adjustment value obtained accordingly for the 3D object in the viewer's binocular view may also be different, which helps to improve the anti-vertigo effect while ensuring the 3D effect.

In some other embodiments proposed by this application, this application can record the physiological information of the viewer obtained each time, and record the previously obtained physiological information as historical physiological information after obtaining the current physiological information. In this way, after obtaining the above In the process of adjusting the parallax value, this embodiment can also read the historical physiological information obtained last time, and compare the currently obtained physiological information with the historical physiological information (such as ratio calculation to obtain the corresponding rate of change; value calculation, to obtain the corresponding difference, etc.), determine the fourth change value between the current physiological information and historical physiological information, and then, referring to the implementation described above, according to the fourth change value, obtain the eyes for the viewer The implementation method of the parallax adjustment value of the 3D object in the view is similar to the implementation method of step S64, which will not be described in detail in this application.

Step S65 , updating the image data of the 3D object output by the display screen according to the parallax adjustment value.

Regarding the implementation process of step S64 and step S65, reference may be made to the description of the corresponding part of the above embodiment, and this embodiment will not describe in detail here. This application does not limit the relationship between the third change value and the parallax adjustment value of the binocular view, and can refer to but not limited to the method and representation of the relationship described above, such as a pre-built linear model, or The pre-configured association relationship tables, etc., can be determined according to the situation.

To sum up, in the process of dynamically adjusting the parallax of the binocular view of the naked-eye 3D object according to the change value of the physiological information of the viewer, this embodiment can directly compare the dizziness level according to the current physiological information without determining the current vertigo level of the viewer. Based on the change value of the initial physiological information, dynamically and accurately adjust the parallax of the 3D object in the binocular view, and then update the image data of the display screen output or the 3D object to be output, and reduce the naked-eye 3D on the basis of ensuring the 3D effect to the greatest extent. Shows dizziness while watching.

It should be noted that for the naked-eye 3D image processing methods described in the above embodiments, when it is determined that the viewer is currently in a state of vertigo, the above-mentioned obtained parallax adjustment value for the 3D object in the viewer's binocular view can represent a reduction corresponding to The numerical value of the adjustment direction of the current parallax of the 3D object, such as expressed by negative numbers.

If the viewer is not currently in a dizzy state, the current naked-eye 3D display effect can be maintained. Optionally, because of this way of adjusting the parallax, the distance between the real focus plane and the actual focus plane is shortened (that is, the virtual depth of field is compressed to a smaller range), reducing the feeling of vertigo, which will reduce the 3D effect to a certain extent , the present application hopes to improve the naked-eye 3D display effect to the greatest extent while ensuring that the viewer does not feel dizzy. On the basis of ensuring that the viewer does not have dizziness, the parallax of the binocular view of the corresponding 3D object can be increased, that is, The corresponding parallax adjustment value obtained above may represent a value that increases the adjustment direction of the current parallax of the corresponding 3D object, such as using a positive number to express, etc. The implementation process is similar to the implementation process of reducing the parallax of the binocular view, and this application does not detail.
