Problems solved by technology

[0003] In the related art, gesture recognition can be used to determine the information input by the user. According to the gesture recognition process of the related art, the mobile device needs to analyze and process the image collected by the camera device to determine the hand position of the target user, and then determine the hand position according to the user's hand. User gestures, the image processing of this technical solution requires a large amount of computation, and if more than one user's hand appears in the image, it may cause the mobile device to fail to recognize the target user's hand and thus fail to realize effective information input

Abstract

The present disclosure relates to a gesture recognition method and device. The method includes: determining depth information of each pixel point in each to-be-processed image according to the to-be-processed images collected by the two or more cameras, where the depth information is used to represent the actual depth corresponding to each of the pixel points. The distance between the object point and the mobile device; the to-be-processed image area of ​​each to-be-processed image is determined according to the depth information; the target user's gesture is determined according to the image information of the to-be-processed image area. The technical solution of the present disclosure can effectively solve the problem of a large amount of image processing computations caused by processing the entire image to be processed in the related art, and solves the problem in the related art that if more than one user's hand appears in the image, effective information cannot be realized The problem of input improves the user experience of inputting information in VR.

Description

technical field [0001] The present disclosure relates to the field of virtual reality (Virtual Reality, VR) technology, and in particular, to a gesture recognition method and device. Background technique [0002] With the rapid development of virtual reality technology based on mobile devices, users can use virtual reality helmets combined with mobile devices to implement various application functions in a virtual reality environment, such as using virtual reality helmets to play online games on mobile devices. When a user uses a virtual reality headset, human-computer interaction is often involved. [0003] In the related art, gesture recognition can be used to determine the information input by the user. According to the gesture recognition process of the related art, the mobile device needs to analyze and process the images collected by the camera device to determine the hand position of the target user and then determine according to the user's hand. User gesture, the i...
