Human body posture capturing system

Abstract

The invention discloses a human body posture capturing system, and belongs to the field of posture detection. The human body posture capturing system is used for solving a problem that capturing of human body postures using a conventional optical capturing system is difficult to realize because the conventional optical capturing system is easily influenced by the environment. The human body posture capturing system comprises 12 data acquisition nodes, 2 data receiving nodes, and a host computer used for receiving posture data; the 12 data acquisition nodes are placed at different positions ofa human body for measuring of the movement postures of different human body parts, and are used for sending posture data to the data receiving nodes; the data receiving nodes are connected with the host computer through serial ports, and sending received data from the data acquisition nodes to the host computer for process. The human body posture capturing system can be used for measuring triaxialaccelerated speed, triaxial angular velocity, and triaxial magnetometers; a speedometer and a magnetometer are adopted for posture direction estimation, accurate three dimensional all posture solvingis realized via combination of a gyroscope and linear kalman filtering; influences of the external factors are avoided; real-time capturing of human posture is realized; and accurate recurrence of human body motions is realized.

Description

technical field [0001] The invention relates to the field of gesture detection, in particular to a motion gesture capture system. Background technique [0002] Existing motion capture is applied to human motion recognition, aircraft attitude analysis, etc. These applications are to filter and integrate the inertial data information we have obtained, and analyze it through a series of algorithms to obtain the final result, which can be The reconstruction of the three-dimensional movement of the human body can also be the analysis of the attitude of the aircraft or objects. These are challenging research topics, which have an important role in promoting bionic engineering, medical engineering, sports competition and game animation.

Problems solved by technology

[0003] Commonly used motion capture technologies mainly include: 1. Acoustic type, this method has a large delay and lag, poor real-time performance, generally not very high accuracy, and is easily disturbed; 2. Optical type, the system is expensive , the whole system is complicated to use and is easily affected by the environment. 3. Mechanical type, which is very inconvenient to use. The mechanical structure greatly hinders and restricts the operator's actions, which is not conducive to the use of the operator.
