微型运动传感器的动作捕捉技术分析及其应用

Analysis and Application of Micro Motion Capture Technology by Using Motion Sensors

为了达到更好的人体运动捕捉效果,对微型运动传感器的运动捕捉技术进行分析,通过在人身体上布设三轴陀螺仪、三轴加速度计和三轴地磁传感器,获得传感器数据融合处理之后得出人体的位移和姿态角,将获得的数据实时上传至计算机利用OpenGL实现人体运动的实时再现。利用文章提出的运动捕捉技术采集测试者的动作,效果较好,说明提出的算法性能良好。

In order to achieve a good human motion capture effect, the article analyzes the motion capture technology of the mi- cro-motion sensors. A three-axis gyroscope, a three-axis accelerometer and a three-axis geomagnetic sensor are laid on the hu- man body to obtain the sensor data and then the data are fused to obtain the human body displacement and attitude angle. The data obtained will be uploaded to the computer in real time, and using OpenGL real-time human motion can be reproduced. Fi- nally, tests are carried out, the motion capture technology proposed can capture the tester＇s action better, hence, it verifies al- gorithm can work well.
