- the processor calculates the spatial coordinates of the specific gesture relative to the optical center of the camera according to the image obtained by the camera and the predicted depth information of the image, using the internal and external parameter data of the camera.
- S302 Trigger the first display screen to display the first interface image according to the gesture information.

- the present application is not limited to the above two solutions, and other solutions are also possible.
- the size of the sub-image displayed on the source display which can be a fixed value or a variable value.
- the processor continuously acquires the images collected by the camera in subsequent times, and if the distance between the fingers in the identified specific gesture continues to decrease, the size of the sub-image displayed on the source display screen can be controlled to also decrease continuously.
- the processor controls the source display screen to display not only the sub-image, but also position information such as the identification of other display screens that can receive the sub-image, the orientation information of the other display screen relative to itself, and the like. Since the position of each display screen has been fixed when the vehicle leaves the factory, for each display screen, the orientation information of other display screens around itself is fixed, and the position between the display screen and the display screen can be fixed.
- the bearing information is stored in the memory in advance.
- the orientation information between the display screens can be represented by a vector formed between the positions of the two display screens.
- the center of the display screen 101-2 is the origin of the spatial coordinates (X0, Y0, Z0).
- Store the coordinate positions between each display screen determine the coordinates (X, Y, Z) of each other display screen in the coordinate system with the center of the display screen 101-2 as the origin of the spatial coordinate, and then calculate the relative
- the calculated vector M is used as the orientation of each other display screen relative to the display screen 101-2.

- the source display screen is The pattern of a display screen can be virtualized, and the orientation and name of each display screen relative to the source display screen can be displayed in text at the same time, and the corresponding pattern of each display screen can be set on the edge of the source display screen according to the orientation relationship. near the physical display.
- the processor controls the source display screen to generate a sub-image to be presented in the middle of the source display screen
- the position of the sub-image in the source display screen at this time and the gesture's relationship can be obtained by obtaining the spatial coordinates of the gesture in the camera image obtained at the corresponding moment.
- the spatial coordinates establish a mapping relationship, so that when the gesture moves subsequently, the sub-image moves in the corresponding direction and proportional distance relative to the position of the sub-image at the current moment according to the direction and distance of the gesture movement.
- the processor may receive each image or video stream captured by the camera in real time, and may also receive images or video streams captured by the camera at regular intervals, which is not limited in this application. Therefore, the "next image or the next frame of image” mentioned below does not mean two consecutive images or two frames of images captured by the camera, and may be several (frames) or dozens of (frames) images in between.
- the processor After the processor detects the specific gesture, if the specific gesture is not continuously detected in the subsequent one or more frames of images, the processor can control the source display screen to no longer display the sub-image and position information. For example, the processor does not recognize the specific gesture in the next frame or frames of images after the specific gesture is detected for the first time. It may be that the user's gesture changes, or the gesture moves outside the shooting range of the camera, etc., resulting in the next frame. Or if there is no specific gesture in the multi-frame images, the processor can send a control instruction to the source display screen to control the source display screen not to display the sub-image and position information.
- the processor determines to trigger the function corresponding to the specific gesture after detecting that the specific gesture exceeds a certain number of times. For example, if the processor acquires the specific gesture multiple times in the sensing information within a preset time, the processor may consider that a valid gesture is acquired, and trigger the corresponding function. For another example, a specific gesture is detected in multiple frames in an image acquired by the camera within a preset time, and exceeds a preset threshold.
- the processor can send control instructions to the source display screen to make the source display screen display sub-images and position information; if it is detected that the number of images including a specific gesture is less than the preset threshold, the processor does not perform subsequent operations, and this The detected results are discarded or deleted.
- the processor detects that the next frame or multiple frames of images also include a specific gesture, and compared with the previous frame or the image in which the specific gesture is detected for the first time (that is, the ith image or the jth frame of the video stream),
- the position of a specific gesture changes, it can be calculated according to the spatial coordinates (x0, y0, z0) of the specific gesture calculated by detecting the next frame or multiple frames of images, the image of the previous frame, or the image where the specific gesture is detected for the first time.
- the trigger sub-image is displayed on the second display screen.
- the condition for triggering the display of the sub-image on the second display screen is that the distance between the detected first position information and the second position information is greater than a set threshold.
- the first position information refers to the spatial coordinates of the specific gesture relative to the camera in the image in which the characteristic gesture is detected for the first time (that is, the ith image or the jth frame image in the video stream), and the second position information refers to the next frame or more.
- the spatial coordinates of the specific gesture relative to the camera in the image after the frame that is, the i+nth image or the j+nth frame image in the video stream, where n is a positive integer greater than zero).
- the processor calculates the movement vector m of a specific gesture in the image after the next frame or multiple frames are captured by the camera, combined with the normal vector n of the source display screen plane, it calculates the translation of the projection of the movement vector m to the source display screen plane. vector m1. Then, the processor can determine the moving direction of the sub-image on the source display screen according to the direction of the translation vector m1, which can be based on the modulo length of the translation vector m1 and the relationship between the preset modulo length and the moving distance of the sub-image on the source screen. A scale relationship that determines how far the sub-image on the source display is moved. Finally, the processor can control the sub-image on the source display screen to move from the center of the plane along the direction of the translation vector m1 by a proportional length of the translation vector m1, so that the sub-image moves with the movement of the user's gesture.
- the processor can send a control command to the source display screen according to the received image processing result each time, so that the sub-images are displayed in different positions on the source display screen, so that the sub-images can be displayed at different positions on the source display screen. Move with certain gestures. If the processor detects that the sub-image moves with a specific gesture, and some or all of the interface is not displayed on the source display screen, the processor can send a control instruction to the target display screen at the same time to make the target display screen display the sub-image Interface not shown on the source display.
- the processor can determine, according to the distance moved by the specific gesture, that when the sub-image is moved to be displayed on the target display screen, the controller sends a control instruction to the target display screen, and the control instruction is used to make the target display screen.
- the display screen displays the APP icon, or the target display screen displays the interface after the APP runs.
- this application provides two judgment conditions as examples, which are not limited in this application, for example:
- a threshold is preset in this application. After determining the target display screen according to the movement vector m, the processor can calculate the modulo length of the translation vector m1 according to the motion vector m. If the modulo length is greater than the set threshold, the sub-image Move to the destination display; if the modulo length is not greater than the set threshold, the sub-image is still moving on the source display.
- the center point of the sub-image moves out of the source display.
- the center point of the sub-image moves out of the source display screen as the limit.
- the processor can detect the position of the sub-image on the source display screen in real time. The border on the display screen or not on the source display screen indicates that half of the sub-image has moved out of the source display screen at this time, then move the sub-image to the target display screen; if the center point of the detected sub-image is on the source display screen , indicating that at this time no half of the sub-image is moved out of the source display screen, and the sub-image is still moving on the source display screen.
- the present application can also use the area of the sub-image to move out, the size of the long side of the sub-image, etc. as the judgment condition, which is not limited here.
- the effect displayed on the interface of the source display screen at this time is shown in FIG. 8 .
- the part of the sub-image removed from the source display screen may not be displayed, or the part of the sub-image removed from the source display screen may be displayed, as shown in Figure 9, so that the user can more intuitively see the part of the sub-image moved by himself. Which display the image goes to and the effect of the movement.
- the processor can increase or decrease the resolution of the sub-image to the resolution of the target display, and then send it to the target display display on the display to prevent the sub-image from moving to the target display to display abnormally.
- the processor determines When the image is moved to the target display screen, the size or aspect ratio of the two can be compared, and the size or aspect ratio of the sub-image can be adjusted so that the sub-image can be displayed normally on the target display screen.
- the processor can keep the original size of the sub-image and display it on the target interface, as shown in Figure 10, or increase the sub-image size so that the sub-image is displayed on the target display at its maximum size, as shown in Figure 11; if the size, long-side, and short-side dimensions of the target display are all smaller than the source display or the sub-image, the processor can Reduce the size of the sub-image so that the sub-image can be displayed on the target display normally; if the size of the long side and the short side of the target display is smaller than the source display or the sub-image, the processor can reduce the size of the sub-image Make the size of the long side match the size of the long side of the target display screen, or reduce the size of the sub-image until the size of the short side matches the size of the short side of the target display screen, and then display it on the target display screen, as shown in Figure 12.
- the processor After the sub-image is moved to the target display screen, if the processor receives the camera image captured by the camera, the specific gesture should not be included. At this time, for the user, the transition of the gesture should be converted from a specific gesture to a non-specific gesture of "open five fingers", "open thumb and index finger". Exemplarily, the processor does not receive a camera image including a specific gesture within a set period of time, or detects a specific gesture such as "spread five fingers and gradually approach the target display screen", or receives three consecutive taps on the target display screen. In other ways, the "multi-screen interaction" function can be turned off to save power consumption and computing costs.
- the processor After the sub-image is moved to the target display screen, if the processor receives the camera image captured by the camera also includes a specific gesture, it can default to the user to share the content displayed on the source display screen with multiple screens for the second time.
- the controller may perform the implementation process in steps S301 to S303 again.
- the processor may first mark two specific gestures, and then execute the implementation process in steps S301 to S303 according to the marked multiple specific gestures, so as to realize the content displayed on the source display screen at the same time Multiscreen sharing to multiple target displays.
- the processor can share the content displayed on the source display screen to the two target display screens, the source display screen can simultaneously display sub-images corresponding to two specific gestures, and the sub-image moves. direction and other information, so that the user can intuitively see the moving process of the two sub-images.
- the processor after the processor detects that the image captured by the camera includes a specific gesture, it can convert the content displayed on the source display screen into a sub-image, and display other display screens that can display sub-images on the source display screen
- the user can intuitively see the movement direction of the subsequent gesture, and then determine the target display screen according to the movement direction of the specific gesture, and control the sub-image on the source display screen to follow the movement direction of the specific gesture. Move and move, when it is detected that the distance moved by a specific gesture is greater than the set threshold, the sub-image is moved to the target display screen, so as to realize the multi-screen interaction function.
