基于惯性传感器的动作捕捉系统设计

The Design of Motion Capture System based on Inertial Sensor

摘要:

针对传统的如光学式、机械式等动作捕捉系统在成本、使用环境及精度等方面各有优劣的特点,设计了一套基于惯性传感器的动作捕捉系统,通过在人体各部位佩戴惯性传感器节点,实时采集各部位的运动惯性数据,通过WIFI通信发送至数据处理终端,对数据进行存储和显示。经实验验证所设计动作捕捉系统能够正确采集人体惯性运动数据,系统的使用不受时间和地点的限制,具有成本低廉、穿戴方便和操作简单等特点,可以深入应用于医学、体育和军事等多个领域。

Abstract:

In view of traditional motion capture systems such as optical and mechanical which have their own advantages and disadvantages in terms of cost, application environment and accuracy, a motion capture system based on inertial sensor is designed. By using inertial sensor nodes in various parts of the human body, the motion data is collected in real time, and sent to the data processing terminal to store and display through WIFI. The experimental proved the designed motion capture system can correctly collect the inertial motion data. The system is not limited by time and place, and has the characteristics of low cost, convenient wearing and simple operation. It can be applied to various fields such as medicine, sports and military, etc.
