TECHNICAL FIELD
[0001] The present application relates to the technical field of display data integration processing, in particular to a display data integration processing system and method based on multi-sensor fusion. BACKGROUND
[0002] Mobile display, also known as mobile smart screen, is also called "buddy machine" on the network. It is composed of a screen and a movable floor stand. As a multifunctional product integrating TV, tablet and sound in recent years, mobile display is mainly used in home scenarios to realize course learning, video fitness and other functions. However, in the current technical development, mobile display still has certain intelligent defects, especially in the main fitness learning scenario. Due to different movements of fitness content, users often need to turn their bodies or face away from the mobile display in certain movements, which causes the user to be unable to watch the subsequent movements of the fitness video in time, causing certain disturbance. At the same time, different users have different levels of mastery of fitness movements. Therefore, there is currently a lack of mobile display that can make intelligent feedback according to the user's own behavior. SUMMARY
[0003] The purpose of the present application is to provide a display data integration processing system and method based on multi-sensor fusion to solve the problems in the prior art.
[0004] To achieve the above purpose, the present application provides the following technical scheme: a display data integration processing method based on multi-sensor fusion, the method comprising the following steps:
[0005] S1. A plurality of sensors are arranged around the mobile display to identify user behavior movements and mobile display peripheral environment data and feed back to the mobile display data integration platform;
[0006] S2. The mobile display data integration platform integrates, analyzes and processes the data to form a mobile start instruction and a mobile termination command;
[0007] S3. Based on the mobile start instruction and the mobile display peripheral environment data, the mobile display is controlled to move intelligently and stop moving when the mobile termination command is reached;
[0008] S4. Identify user behavior movements to control the mobile display to continue video display.
[0009] According to the above technical scheme, the identification of user behavior movements and mobile display peripheral environment data comprises:
[0010] Based on the plurality of sensors arranged around the mobile display, the center point of the mobile rod of the mobile display is taken as the center of a right-angle coordinate system in the space of the region formed in the horizontal and vertical directions, the objects in the region are monitored, and the object coordinates are marked.
[0011] The user and the object are distinguished based on facial recognition, and the distance between the center of the mobile display and the center of the user's eyebrows is used to determine the moving radius; the moving radius is determined according to the average value of the distance between the center of the mobile display and the center of the user's eyebrows in the latest use time T after the user turns on the device this time, and the distance is taken every period T1, T1 is less than T, if the use time after turning on the device is less than T, the use time is directly selected, if it is less than T1, it is not selected;
[0012] After determining the moving radius, the intersection of the vertical line of the eyebrow center and the ground is taken as the first moving center, and the moving area on the ground is formed according to the moving radius, and the data integration platform of the mobile display is fed back to obtain the object coordinate data existing in the moving area on the ground, which is marked as an obstacle avoidance point.
[0013] According to the above technical scheme, it also includes:
[0014] Obtain the video data information played by the mobile display, analyze the action data of the characters in the video, and form a video character action data set;
[0015] Use the plurality of sensors arranged around the mobile display to identify the action data of the user, form a video frame under a set fixed period, and compare the action data of the video frame with the action data of the video character action data set to obtain the action data similarity of the user at different times.
[0016] According to the above technical scheme, in steps S2 to S3, it also includes:
[0017] Construct a historical database, which stores the action data similarity of the user at different times, and the rotation angle and user behavior corresponding to the similarity;
[0018] The user behavior includes positive feedback behavior and non-positive feedback behavior, the positive feedback behavior refers to the user watching the display after a certain similarity; in this application, the positive feedback behavior actually refers to the user turning around or looking at the display when the rotation angle reaches a certain degree, that is, when the user moves the display with his back or sideways, which means that the user is not familiar with the video action and needs to continue watching the display to learn, which is the positive feedback behavior; the non-positive feedback behavior refers to the user not watching the display;
[0019] The rotation angle refers to the angle between the positive direction of the user's eyebrow center and the initial direction, the positive direction of the user's eyebrow center refers to the ray formed by taking the eyebrow center as the vertex and the front as the positive direction; the initial direction refers to the positive direction of the eyebrow center when the user initially watches the display, and the angle is 0 when the user initially watches;
[0020] The data in the historical database is selected and formed into a data combination, denoted as [Si , θ i , A0], wherein S0 represents the action data similarity of the user at time i, θ i represents the rotation angle at time i, and A0 represents the user behavior in the time range [i, i+u]; u represents a constant term set by the system.

The behavior group corresponding to the output result is recorded as the current behavior.
[0024] When the current behavior belongs to the positive feedback behavior, the instruction analysis is started.
[0025] The instruction includes a movement start instruction and a movement termination instruction. The movement start instruction indicates that the movement is started in the positive direction of the center of the eyebrow of the current user in the initial direction, and the obstacle avoidance processing is realized during the movement. The movement termination instruction indicates that the movement is stopped when the first rotation angle is within the range set by the system. The first rotation angle refers to the difference between the rotation angle and the angle of movement under the movement start instruction. In this application, due to the movement of the display, the difference of the rotation angle gradually decreases, and when it is within a certain difference range, it is within the user's field of view, and the termination instruction is issued.

[0034] The output end of the integrated analysis processing unit is connected with the input end of the instruction output unit.
[0035] According to the above technical solution, the instruction processing module includes instruction control.
[0036] The mobile start instruction means starting to move in the direction of the current user's eyebrow center, and realizing obstacle avoidance processing in the moving process; and the mobile termination command means stopping when a first rotation angle is within a system set range, and the first rotation angle means the difference between a rotation angle and the angle of moving under the mobile start instruction.
