Single base station portable VR system based on wireless human motion capture and optical positioning

Abstract

A single base station portable VR system based on wireless human motion capture and optical positioning is provided. The system comprises: a motion sensor module, for monitoring a three-dimensional spatial orientation of a human limb; an optical positioning module, for monitoring absolute spatial positions of a human body and a VR head display; an arithmetic module, for, according to data of the motion sensor module and the optical positioning module, calculating and acquiring a motion change track of the position and the orientation of the human body and the limb in the three-dimensional space; and a VR terminal device, which comprises a smart phone and the VR head display, wherein a built-in VR program of the smart phone is configured to refresh display content according to the motion change track of the position and the orientation, the position and orientation information of the limb including the hands is applied to the VR program, and the VR image is output for the user to receive and view through the VR head display. The system provided by the present invention has good portability, has no space and site limitation, and does not require a fixed use site; and only by using one optical tracking base station, a 360 degree full range of position tracking can be achieved and the human motion can be introduced into the VR system.

Description

technical field [0001] The invention belongs to the technical field of VR applications, in particular to a single base station portable VR system based on wireless human motion capture and optical positioning. Background technique [0002] The current VR technology and equipment are mainly divided into three categories: [0003] 1. Professional-grade VR based on time stamp optical positioning [0004] A typical product is HTC VIVE VR. Including 1 VR headset, 1~2 handles, and 2 positioning base stations. The positioning base station sends lasers containing time stamp information at a certain frequency. There are multiple laser receivers on the head display and the handle. According to the time stamp information in the laser received by the laser receiver, the distance between the VR head display and the positioning base station can be calculated. In this way, the positions of the VR headset and the handle can be determined. Because the VR headset and handle must directly ...

Problems solved by technology

[0007] 3. VR helmets without optical positioning

Because there is no optical tracking unit, the position of the VR helmet and hands cannot be known, so there is no displacement of the viewing angle in the VR content
