Abstract

The application provides a multi-person environment gesture control right acquisition method, network equipment and a storage medium, wherein the method comprises the steps of acquiring coordinates (x, y, z) of a spatial position identification information point P of a gesture with acquired control right, which is cached in a previous frame, acquiring a multi-person gesture information set handlist = { hand0, hand1, hand2, & gt, handn }, wherein n represents the number of hands in the current frame, each gesture in the set contains hand key point coordinates for identifying the gesture, judging the number of gestures in the multi-person gesture information set handlist, and outputting the hand closest to the P coordinates in the current frame as the gesture with the acquired control right if the number of the gestures is larger than 1. According to the embodiment of the application, the gesture for acquiring the control right in the current frame can be recognized under the environment of multiple gestures, so that confusion of an interactive system is avoided.

Description

Multi-user environment gesture control right acquisition method, network equipment and storage medium Technical Field The present application relates to the field of communications devices, and in particular, to a method for acquiring gesture control rights in a multi-user environment, a network device, and a storage medium. Background The gesture control can realize non-contact operation, the application is wider and wider, and the operation of manual interaction through gesture recognition is gradually becoming a mainstream control mode. However, in the gesture recognition process, the system can only recognize one gesture, and gestures of multiple persons can occur in the camera recognition, so that the system recognition is confused. Disclosure of Invention In order to overcome the problems in the related art, the application provides a multi-user environment gesture control right acquisition method, network equipment and a storage medium. According to the multi-person environment gesture control right acquisition method of the first aspect of the embodiment of the application, Acquiring coordinates (x, y, z) of a spatial position identification information point P of the gesture of acquiring control right cached in the previous frame; Acquiring a plurality of hand gesture information sets handlist = { hand0, hand1, hand2, &.. handn }, wherein n represents the number of hands in the current frame, and each hand gesture in the set comprises hand key point coordinates for recognizing the hand gesture; And judging the number of gestures in the multi-person gesture information set handlist, and if the number of the gestures is larger than 1, outputting the hand closest to the P coordinate in the current frame as the gesture for acquiring the control right. Preferably, the number of gestures in the multi-user gesture information set handlist is judged, if the number of the gestures handlist is equal to 1, the current gesture is output as a gesture for acquiring control right, and the P coordinate is updated; If handlist is equal to 0, the P coordinate is null. Preferably, the method further comprises the steps of judging whether the P coordinate is empty or not, if not, judging the number of gestures in the multi-user gesture information set handlist to obtain a gesture with the acquired control right, traversing handlist if the P coordinate is empty, and sequentially taking the key point coordinate of one gesture at a time to perform gesture conversion; Judging whether the gesture after conversion is a gesture for acquiring control rights; if the gesture is not the gesture, the key point coordinate of the next gesture in handlist is acquired again for gesture conversion and whether the gesture is the gesture for acquiring the control right is judged. Preferably, the P coordinate (x, y, z) is algorithmically derived from the gesture keypoints. Preferably, the P coordinate (x, y, z) is obtained from the gesture keypoints by an algorithm, including processing the gesture keypoints by an average or weighting algorithm.
