Description

Technical Field

[0001] The present invention belongs to the field of virtual reality interaction technology, and in particular to an optical motion capture method and system for VR equipment. Background Art

[0002] Virtual reality interactive technology is a popular digital technology that involves multiple cutting-edge technology fields. It is a virtual world created on the basis of computer technology, that is, a realistic virtual environment. Users can use various interactive devices to communicate with the virtual environment in various forms (including interaction between people in virtual space) and have a multi-sensory experience. The user's simulation has an immersive interactive feeling.

[0003] With the development of virtual reality and Internet technology, in order to meet the interaction needs between different computing terminals that are widely distributed geographically, distributed virtual reality came into being. Computing terminals distributed geographically in different regions build virtual environments locally, and then interact or roam in a shared three-dimensional virtual environment by controlling virtual node avatars. However, at present, multi-person interaction based on virtual reality can only realize the sharing of role positions in the same three-dimensional virtual scene. The skeleton and position data of real users are collected through motion acquisition equipment, and the corresponding human body model is established according to the skeleton and position data of real users, and the model is bound to the three-dimensional environment of the server. However, in the multi-person interaction scene, it only shares the position information of the virtual person with other users, and cannot realize continuous motion capture between users. Users can only see the position and posture of the virtual person from the three-dimensional animation, and cannot receive the motion data information of the virtual person in time, so they cannot respond to the changes of the motion information of the virtual person in real time.
