Human motion information capturing system based on micro-mechanical sensor

Abstract

The invention discloses a human motion information capturing system based on a micro-mechanical sensor. The human motion information capturing system comprises a plurality of sensor units, a main controller system and a data processing and graph rebuilding system, wherein the plurality of sensor units are used for obtaining motion posture data of every feature point position of the human body; the main controller system is used for performing processing on the basis of the human motion posture data obtained through a corresponding sensor network sensor unit and performing data transmission in a bluetooth module wireless pass-through mode; and the data processing and graph rebuilding system is provided with personal computer (PC) software and BVH files, can perform calculation according to the motion posture data obtained by processing through the main controller system and rebuilds a human motion posture model in real time. Every sensor unit, the main controller system and the data processing and graph rebuilding system are connected in sequence. Real-time data capturing of motion of the whole human body can be achieved in a wireless mode through the human motion information capturing system based on the micro-mechanical sensor, and the human motion information capturing system can be applied to motion control of virtual characters or robots in animations and games.

Description

technical field [0001] The invention relates to the technical field of motion image capture and processing, in particular to a human body motion information capture system based on a micromechanical sensor. Background technique [0002] Motion capture technology is a technology that accurately measures the movement of moving objects in three-dimensional space. Through several inertial measurement nodes bound to the human body, the motion data on the key points of the human skeleton is obtained, and the wireless data transmission method is used to transmit it to the PC. After data processing and calculation, the spatial coordinates of the key points in different time units of measurement are obtained. (X, Y, Z), and apply computer graphics technology to display and reconstruct simulated human body movements. [0003] In animation creation, the motion control of 3D animation model is a huge workload, and it is also the key to improve the efficiency of animation creation. In ...
