In order to illustrate the technical solutions of the present invention, specific examples are used below to illustrate.

Embodiment one:

Referring to FIG. 1, FIG. 1 is a schematic flowchart of a method for switching modes of a mobile terminal provided in Embodiment 1 of the present invention. As shown in the figure, the method may include the following steps:

Step S101 , in a predetermined state, after receiving an instruction to switch modes, turn on the camera to collect images.

In the embodiment of the present invention, the predetermined state is a preset state of the terminal, which may be a lock screen state, a main interface state, etc. of the terminal. The instruction to switch modes is a preset instruction input by the terminal user, which may be an instruction input by the user through the touch screen, or an instruction input by the user through a button or a combination of buttons set on the terminal. As a preferred embodiment, the predetermined state is the lock screen state, and the instruction to switch modes is an instruction to slide the user's finger from left to right on the touch screen, that is, in the lock screen mode, the terminal receives the After the instruction of sliding from left to right is output by the control screen, the built-in camera of the terminal will be turned on, and the camera is used to collect images.

Step S102, identifying gestures in the images captured by the camera, and comparing and identifying the identified gestures with a plurality of gesture passwords stored in advance.

In the embodiment of the present invention, the camera collects various gestures made by the user in front of the terminal camera. In order to enable the camera to capture clear and complete gesture images, it can be set to display the camera in real time on the terminal screen after the camera is turned on. For the captured image, the user can adjust the position of the gesture according to the gesture image displayed in real time on the terminal screen so that the camera can capture a clear and complete gesture image. The gesture may be a two-dimensional static gesture, or a two-dimensional dynamic gesture. After the image is collected, the skin color area will be extracted from the image and the threshold will be set to binarize the image. Noise interference will be eliminated through morphological processing. Finally, the connected domain search will be performed to obtain the recognized gesture image, and then the recognized gesture image will be combined with Multiple pre-stored gesture passwords are compared and recognized. If it is a two-dimensional dynamic gesture, multiple images containing gestures collected continuously can be recognized, and finally a two-dimensional dynamic gesture can be obtained.

As a preferred embodiment, after recognizing the gesture in the image collected by the camera, the method further includes:

Generate gesture information for user confirmation according to the recognized gesture;

After receiving the confirmation information from the user, compare and identify the recognized gesture with multiple gesture passwords stored in advance.

In the embodiment of the present invention, since the user compares and recognizes a certain gesture with multiple gesture passwords stored in advance in front of the terminal camera, due to the influence of posture, angle or light, the gesture collected by the camera and recognized may be There is a problem of inconsistency with the gestures that the user wants to make, so after recognizing the gestures in the images collected by the camera, a virtual gesture information will be generated according to the recognized gestures, and the gesture information will pass through the terminal screen in the form of images show. For example, when the user makes an "OK" gesture through a gesture, due to the influence of the user's angle, posture, light, etc., the image collected by the camera may appear in the gesture shape of "OK" after recognition, or there may be only three The shape of the fingers, when the pre-stored password is the gesture shape of "OK", it will appear even if the gesture made by the user is the gesture shape of "OK", but due to the angle posture, it will be recognized as the shape of three fingers , the recognized shape of the three fingers will be compared and recognized with the pre-stored gesture password, resulting in an error in the comparison and recognition result. Therefore, after the gesture is recognized, gesture information in the form of an image is generated for the user based on the recognized gesture. Confirm so that the user can adjust the angle of the gesture action made by the gesture information.

It should be noted that, before the recognized gesture is compared and recognized with multiple gesture passwords stored in advance, a gesture is correspondingly set for each terminal mode as a gesture password for entering the terminal mode.

Step S103, if the recognized gesture matches any one of the gesture passwords stored in advance, enter the terminal mode corresponding to the gesture password matching the recognized gesture.

In the embodiment of the present invention, usually the user will set multiple terminal modes on the terminal, and set a gesture password for each terminal mode at the same time. When the recognized gesture matches any of the multiple gesture passwords stored in advance, enter The terminal mode corresponding to the gesture that matches the recognized gesture needs to recognize the image captured by the camera, and the recognition result may be affected by the ambient light intensity, user posture, etc., so even if the user makes the same gesture, it may be recognized There will also be differences in the results. At this time, it is necessary to set a matching threshold. If the matching degree between the recognized gesture and any one of the multiple gesture passwords stored in advance is greater than the matching threshold, enter the For the terminal mode corresponding to the matched gesture password, if the matching degree between the recognized gesture and any one of the multiple gesture passwords stored in advance is less than or equal to the matching threshold, there will be no response or a message reminding that the password is wrong.

In the predetermined state, after receiving an instruction to switch modes, the present invention turns on the camera to collect images; recognizes gestures in the images collected by the camera, and compares and recognizes the recognized gestures with multiple gesture passwords stored in advance ; If the recognized gesture matches any one of the gesture passwords stored in advance, enter the terminal mode corresponding to the gesture password matching the recognized gesture. Since the present invention can complete the switching of different modes of the terminal without entering into the mode switching interface, the user's operation of switching between different modes of the terminal can be simplified and the operation efficiency can be improved. Moreover, the invention has the advantages of convenient operation, simple realization, wide adaptability, and strong usability and practicability.

Embodiment two:

Referring to FIG. 2, FIG. 2 is a schematic flowchart of a method for switching modes of a mobile terminal provided in Embodiment 2 of the present invention. As shown in the figure, the method may include the following steps:

Step S201, after receiving the gesture password setting instruction, turn on the camera to collect images.

In the embodiment of the present invention, the two-dimensional gesture can be used as the gesture password, and the user only needs to make a preset action to switch between different modes of the terminal. However, the gesture recognized by the two-dimensional gesture password can only stay in the On the three-dimensional plane, the gestures made by the user cannot be fully recognized. Therefore, three-dimensional gestures can also be used as gesture passwords. Three-dimensional gesture recognition can recognize various hand shapes, gestures, and actions. Since the recognized gesture needs to be compared and recognized with multiple gesture passwords stored in advance, the user needs to preset gesture passwords corresponding to multiple terminal modes. The gesture password setting instruction can be sent by the user through the touch screen, or can be It is issued by the user through the button or combination of buttons on the terminal. After receiving the gesture password setting instruction from the user, the camera is turned on to collect images.

Step S202, selecting a corresponding terminal mode.

Step S203, identifying gestures in the images captured by the camera, and using the identified gestures as gesture passwords for entering the selected terminal mode.

In the embodiment of the present invention, since the gesture password may be a three-dimensional gesture password, depth information usually needs to be included in the recognition of the three-dimensional gesture, and the depth information refers to the distance between different points in the gesture and the camera. Compared with two-dimensional gesture recognition technology, three-dimensional gesture recognition cannot only use a single ordinary camera. Currently, a laser projector can be loaded on the terminal, and a grating with a specific pattern can be placed outside the laser projector. Refraction, so that the final landing point of the laser on the surface of the object is displaced, but because the distance is too short, the displacement caused by refraction is not obvious, so that the technology cannot calculate the depth information too accurately, so 1 meter to 4 meters is optimal distance. However, when the gesture recognition technology is used for switching modes of the terminal, obviously this distance is inappropriate, so this method has limitations. Preferably, a light-emitting element can also be loaded on the terminal, and the photons emitted by the light-emitting element will reflect back after hitting the surface of the object, so that a CMOS sensor can capture these photons emitted by the light-emitting element and emitted back from the surface of the object. Get the time-of-flight of the photon. According to the photon flight time, the distance of the photon flight can be calculated, and the depth information of the object can be obtained.

As a preferred embodiment, two or more cameras can also be used to capture images at the same time, just like humans observe the world with binoculars and insects with multi-eye compound eyes, by comparing the images obtained by these different cameras at the same time The difference between the images is used to calculate the depth information, so as to form multi-angle three-dimensional imaging. That is, the cameras are dual cameras, and the three-dimensional gesture recognition using the dual cameras is specifically:

Recognizing gesture images from images collected by two cameras arranged at different positions, and extracting images of different angles of view of the same gesture from the recognized gesture images;

Obtaining the depth information of key points of the gesture according to the extracted images of different viewing angles of the same gesture;

Three-dimensional gesture information is constructed according to the depth information of the gesture key points.

In the embodiment of the present invention, the two cameras are installed in parallel, and the optical axes of the two cameras are parallel. The two cameras need to collect images at the same time to ensure the consistency of the images of the two cameras. The gesture image is recognized from the images collected by the two cameras, and the image of the same gesture with different perspectives can be obtained. The key points in the gesture image can be selected and the key points can be calculated. The parallax of the corresponding pixel points in two different viewing angle images, and the depth information of the key point is obtained according to the distance between the two cameras, the focal length of the camera and the parallax, and the parallax can be determined using the Census algorithm, Depth information refers to the distance from the key point in the gesture to the lens. First, the Census algorithm is used to calculate the position of the most matching key point around the corresponding position of the key point in the image captured by another camera, and then the distance between the two cameras The distance between the key point in the gesture and the camera is calculated based on information such as the focal length and parallax of the camera, that is, the depth information. Multiple key points in the gesture recognized by the camera can be selected, and the depth information of multiple key points can be calculated separately, and the three-dimensional gesture information can be constructed through the depth information of multiple key points.

It should be noted that a terminal with dual cameras is not limited to only setting a 3D gesture password, and the user can choose to set a 2D gesture password or a 3D gesture password. When a terminal with dual cameras chooses to set a 2D gesture password, Gesture images can be collected and recognized through one of the cameras.

Step S204, in a predetermined state, after receiving an instruction to switch modes, turn on the camera to collect images.

This step is the same as step S101, for details, please refer to the relevant description of step S101, which will not be repeated here.

Step S205, identifying gestures in the images captured by the camera, and comparing and identifying the identified gestures with a plurality of gesture passwords stored in advance.

As a preferred embodiment, the identifying the gesture in the image collected by the camera, and comparing and identifying the identified gesture with a plurality of pre-stored gesture passwords includes:

Recognizing gesture images from images collected by two cameras arranged at different positions, and extracting images of different angles of view of the same gesture from the recognized gesture images;

Obtaining the depth information of key points of the gesture according to the extracted images of different viewing angles of the same gesture;

The three-dimensional gesture information is constructed according to the depth information of the gesture key points, and the constructed three-dimensional gesture information is compared with a plurality of gesture codes stored in advance for identification.

In the embodiment of the present invention, the method for recognizing the user's gesture through two cameras is the same as that described in step S203. It should be noted that if you select a two-dimensional gesture when setting the terminal mode password, it will be automatically recognized as a two-dimensional gesture when the recognition of the switching mode is performed, and the recognized two-dimensional gesture is compared with the pre-stored gesture password Pair recognition; if you select a three-dimensional gesture when setting the terminal mode password, it will be automatically recognized as a three-dimensional gesture when switching modes, and the recognized three-dimensional gesture will be compared with the gesture password stored in advance; if you set the terminal mode password At this time, some terminal modes are two-dimensional gesture passwords, and some terminal modes are three-dimensional gesture passwords. When switching modes, two-dimensional gestures and three-dimensional gestures are recognized, and the recognized two-dimensional gestures and three-dimensional gesture passwords are combined with the pre-stored gestures. The password is compared and identified.

Step S206, if the recognized gesture matches any one of the gesture passwords stored in advance, enter the terminal mode corresponding to the gesture password matching the recognized gesture.

This step is the same as step S103, for details, please refer to the related description of step S103, which will not be repeated here.

It should be understood that in the first and second embodiments above, the size of the sequence numbers of the steps does not mean the order of execution, and the execution order of the steps should be determined by their functions and internal logic, rather than by the implementation of the embodiments of the present invention. process constitutes any qualification.
