Description

Technical field [0001] The invention relates to the field of micromachines (MEMS) and virtual reality, in particular to a virtual reality integrated system based on motion capture technology. Background technique [0002] The posture tracking and restoration technology of moving objects has been widely used in various fields, especially in aerospace and navigation, human body motion posture modeling and other fields. Currently commonly used motion capture technologies mainly include optical motion capture technology and motion capture based on inertial sensors, which are introduced as follows: [0003] Optical motion capture technology: usually attach multiple reference balls / points to the moving target, adopt multiple high-speed cameras and arrange them around the object to be measured, so that the moving range of the object to be measured is in the overlap area of ​​the camera, and the target is acquired through video recognition technology The body refers to the trajectory of t...

AI Technical Summary

Problems solved by technology

But there are also the following problems: the whole system is complex, requiring multiple high-speed cameras and computing platforms, and the system is expensive; the system lock is cumbersome, and can only capture the movement of objects overlapping cameras, and when the movement is more complex, the logo is easy to confuse and block , resulting in erroneous results; at the same time, the optics have relatively high requirements on the environment, and the light intensity has a great influence on the accuracy

[0011] However, most of the existing virtual reality technology is experienced in the form of virtual reality glasses or mirrors, so the degree of immersion and interactivity of virtual reality technology is not high
