Three-dimensional gesture recognition method and system

Abstract

The invention discloses a three-dimensional gesture recognition method and system. The three-dimensional gesture recognition method comprises the steps: acquiring first three-dimensional position information on a hand of a user, wherein the first three-dimensional position information is position information on a first position point of the hand of the user; carrying out predicting calculation on the first three-dimensional position information by using a predefined gesture prediction algorithm so as to obtain second three-dimensional position information and attitude information on the hand of the user, wherein the second three-dimensional position information is position information on a second position point of the hand of the user; inputting the second three-dimensional position information and the attitude information to a pre-modeled three-dimensional hand model, thereby obtaining a three-dimensional gesture corresponding to the hand of the user. According to the technical scheme disclosed by embodiments of the invention, the simulation of real actions of hands in the fields of virtual reality and augment reality is achieved, and thus the effects of recognizing and interacting three-dimensional gestures are achieved.

Description

technical field [0001] The present disclosure generally relates to the field of computer technology, specifically to the field of virtual reality and augmented reality technology, and in particular to a three-dimensional gesture recognition method and system. Background technique [0002] Gesture interaction can provide users with the possibility of natural interaction in different scenarios. It is widely used in many fields such as games, real estate, education, tourism, film and television, etc. Users do not need to wear any equipment to achieve the same interaction as human hands and the natural world. . At the same time, this technology is one of the most critical human-computer interaction technologies in the field of virtual reality and augmented reality applications, and is the basis for better interactive experience or more complex functions. Through gesture interaction technology, the user's sense of reality and immersion when using virtual reality (VR) / augmented r...

Problems solved by technology

The mobile terminal (tablet, mobile phone) uses the gesture interaction of the touch screen. There are mainly eight gestures: long press, touch, slide, drag, rotate, zoom, and shake. The advantage is that it increases portability and simply simulates gesture interaction. Action, its disadvantage is that the gesture interaction action is too simple to simulate the real action of the hand

[0007] It can be seen that most of the current gesture interaction methods cannot fully simulate the real movements of the hands, and cannot be applied in the fields of virtual reality and augmented reality.

However, for this problem, the prior art does not provide an effective solution
