Description

A method, device, AR device and storage device for improving the display effect of virtual objects in an AR device storage medium

technical field

The present invention relates to the technical field of AR devices, and in particular, to a method, an apparatus, an AR device and a storage medium for improving the display effect of virtual objects in an AR device.

Background technique

Augmented Reality (AR) technology is a new technology that "seamlessly" integrates real world information and virtual world information. (visual information, sound, taste, touch, etc.), through computer and other science and technology, simulation and simulation and then superimposed, the virtual information is applied to the real world, perceived by human senses, so as to achieve a sensory experience beyond reality. The real environment and virtual objects are superimposed on the same screen or space in real time.

At present, there are two main display methods for head-mounted AR devices: Video See-Through and Optical See-Through.

The video perspective is to collect the image of the real scene through the miniature camera installed on the AR device, and the computer will superimpose the information and image signal to be added on the video signal of the camera through scene understanding and analysis, and at the same time, the computer-generated virtual scene It is fused with the real scene and finally presented to the user through the display.

The optical see-through type realizes the fusion of the external real environment and virtual information through a pair of transflective optical synthesizers installed in front of the eyes. The real scene is directly presented to the user through the semi-reflective and semi-reflective lens. The virtual information generated by the computer is amplified by the optical system and then reflected by the semi-reflective and semi-reflective lens to enter the eyes. The real scene and virtual information converge on the retina to form a virtual and real superimposed imaging effect.

The problem with the existing optical see-through AR equipment is that the virtual information produced by the computer, such as virtual objects, has its coordinate position determined according to the coordinate system established by the real scene obtained by the camera, that is, determined by the coordinate system constructed according to the camera. The real scene seen by the user is directly obtained by the human eye and determined by the coordinate system formed by the human eye. Due to the deviation of these two coordinate systems, the virtual objects produced by the computer have deviations when they are superimposed on the real scene, resulting in poor effect of virtual and real superposition, that is, the display effect of virtual objects is not good, which affects the user experience.

After step S1, it also includes step S1': adding a virtual object, and acquiring the coordinates of the virtual object in the real environment image coordinate system.

That is, after the image of the real environment is acquired, virtual objects to be added are added according to the acquired image of the real environment, and the coordinates of the virtual objects in the real environment image coordinate system are acquired. It should be noted that the addition here may refer to constructing corresponding virtual objects according to real environment images, or it may refer to adding existing or generated virtual objects to the real environment according to preset adding rules. in the image coordinate system. The virtual objects here can refer to pictures, videos, animations, texts, etc., that is, things that are not in the real environment image and are added by the processor.

Specifically, in step S1 ′, the reference object in the real environment is first identified by the object recognition technology, and the coordinates of the reference object in the real environment image coordinate system are obtained; A virtual object is added with the set position relationship, and the coordinates of the virtual object in the real environment image coordinate system are obtained.

Object recognition technology is a basic technology in the field of computer vision. Its function is to identify what object is in the image and report the position and orientation of this object in the scene represented by the image.

Object recognition technology usually includes the following steps: image preprocessing, feature extraction, feature selection, modeling, matching, and localization.

The main methods of object recognition include: object classification method based on statistics, recognition based on object components, generative method and discriminative method, object recognition method based on model, and object recognition method based on context.

The above steps are described below by taking improving the display effect of the virtual circular vase on the circular desktop in the real environment as an example.

In step S1, a real environment image containing a circular desktop is obtained through the camera of the AR device, and a real environment image coordinate system is calculated and constructed according to the real environment image. The origin of the real environment image coordinate system is the optical center of the camera, the x-axis, and the y-axis Consistent with the x and y axes of the imaging plane, the z axis is the optical axis of the camera and is perpendicular to the x and y axes.

In step S1', after acquiring the real environment image, first identify the circular desktop in the real environment through the object recognition technology, the circular desktop is the above-mentioned reference object, and after the circular desktop is recognized, the circular desktop is positioned , obtain the coordinates (x1, y1, z1) of the center of the circular desktop in the real environment image coordinate system. Then, the virtual vase is added according to the preset positional relationship between the virtual circular vase and the circular desktop. The coordinates of the center of the bottom of the virtual circular vase in the real environment image coordinate system are (x2, y2, z2). The preset is 3 cm to the right of the center of the circular desktop and 5 cm above the virtual circular vase.

S2: Obtain viewing angle information and construct a viewing angle coordinate system.

Specifically, the angle of view information includes information such as the position, state, direction of sight, and angle of view of the eyeball, and the angle of view information may be obtained through an eye tracking technology.

The eye tracking technology includes: iris angle change tracking technology, eyeball and eyeball peripheral feature change tracking technology, and infrared tracking technology.

After obtaining the viewing angle information, the processor of the VR device calculates and constructs a viewing angle coordinate system according to the viewing angle information. The directions of the x-axis and the y-axis of the iris plane are the same, and the z-axis of the viewing angle coordinate system is the viewing direction of the line of sight. In some embodiments, the eye center point may be the pupil center point.

S3: Obtain the coordinate system difference between the real environment image coordinate system and the viewing angle coordinate system.

Specifically, after the real environment image coordinate system and the viewing angle coordinate system are established, the positional relationship between the real environment image coordinate system and the viewing angle coordinate system can be directly known according to information such as the positional relationship between the eyeball and the camera, and viewing angle information. , and then the coordinate system difference between the real environment image coordinate system and the viewing angle coordinate system can be directly obtained.

In some embodiments, the coordinate system difference between the real environment image coordinate system and the viewing angle coordinate system can also be obtained by using a reference object. Specifically, the reference object in the real environment is identified by the object recognition technology, and the coordinates of the reference object in the real environment image coordinate system and the viewing angle coordinate system are obtained; the reference object is calculated in the real environment image coordinate system and the viewing angle coordinate system. The coordinate difference in ; the coordinate difference is the coordinate difference between the real environment image coordinate system and the viewing angle coordinate system.

Continue to take improving the display effect of the virtual circular vase on the circular desktop in the real environment as an example to describe the above steps.

In step S2, the viewing angle information is obtained through eye tracking technology, and a viewing angle coordinate system is calculated and constructed, the origin of the viewing angle coordinate system is the center point of the eyeball, and the x-axis and y-axis of the viewing angle coordinate system are the same as the x-axis of the retinal plane or the iris plane. The directions of the axis and the y-axis are the same, and the z-axis of the viewing angle coordinate system is the viewing direction of the line of sight. Further, since the circular desktop in the real environment has been identified by the object recognition technology in step S1', in this step, the coordinates of the center of the circular desktop in the viewing angle coordinate system are (x3, y3, z3).

In step S3, according to the obtained coordinates (x1, y1, z1) of the center of the circular desktop in the real environment image coordinate system and coordinates (x3, y3, z3) in the viewing angle coordinate system, calculate the center of the circular desktop at The coordinate difference between the real environment image coordinate system and the viewing angle coordinate system, the coordinate difference is (x3-x1, y3-y1, z3-z1), that is, the difference between the real environment image coordinate system and the viewing angle coordinate system.

S4: Acquire the state of eye movement.

Specifically, the movement state of the eyeball, that is, the rotation direction and angle of the eyeball, is tracked through the eyeball tracking technology. Because when the eye moves, the direction of the line of sight changes. If you want to improve the display effect of the virtual object, it is necessary to adjust the coordinates of the virtual object according to the movement of the eyeball, that is, the change of the direction of the line of sight, so as to better match the line of sight of the human eye.

For this step, in other embodiments, the eyeball tracking technology is used to obtain the relevant information of the viewing angle of the eyeball after rotating in a certain direction and angle, and re-establish the viewing angle coordinate system, and the re-established viewing angle coordinate system is the adjusted viewing angle coordinate system. The viewing angle coordinate system.

S6: Adjust the coordinate system difference according to the adjusted viewing angle coordinate system.

For this step, in some embodiments, the position of the real environment image coordinate system and the position of the viewing angle coordinate system adjusted in step S5 can be directly obtained through information such as the position of the eyeball after the movement, the realization direction, that is, the positional relationship between the camera and the camera. relationship, so that the coordinate system difference between the real environment image coordinate system and the viewing angle coordinate system adjusted in step S5 can be directly obtained.

For this step, in other embodiments, the real environment image coordinate system and The coordinate system difference of the viewing angle coordinate system adjusted in step S5. That is, the coordinates of the reference object in the two coordinate systems are subtracted, and the adjusted coordinate system difference can be obtained.

S7: Adjust the coordinates of the virtual object according to the adjusted coordinate system difference.

In this step, the coordinates of the virtual object in the real environment image coordinate system are added to the adjusted coordinate system difference obtained in step S6 to obtain the coordinates of the virtual object in the adjusted viewing angle coordinate system.

Further, the method further includes step S8: projecting the virtual object on the display screen of the AR device with the adjusted coordinates. Projecting virtual objects with adjusted coordinates can effectively compensate for the deviation between the coordinate system constructed by the camera and the coordinate system of the human eye perspective. Overlay effect, that is, to improve the display effect of virtual objects.

Here, the above steps will be described by taking improving the display effect of the virtual circular vase on the circular desktop in the real environment as an example.

In steps S4 and S5, the eye movement state is obtained through the eye tracking technology, and the viewing angle coordinate system is reconstructed according to the eye angle related information after the movement, that is, the adjusted viewing angle coordinate system is obtained.
