人体肢体运动的动态检测和模拟具有极大的医学应用价值。介绍一种采用微机电传感器(加速度计和磁强计)集成制作的微型监测装置,可以用于人体姿态和运动的测量。在姿态和运动的表示方面,采用单次转动和空间转轴结合的方式,计算简便,姿态反映直观,运动特征突出。此外对人体头部运动进行了实际测量和运动模拟。实验证明:该装置能够动态检测肢体的姿态和速度等运动信息,并可快速地进行体态模拟。 The dynamic detection and simulation of human limb movement has great medical value. A micro-monitoring device integrated with MEMS sensors (accelerometer and magnetometer) is introduced to measure the attitude and movement of the human body. In terms of attitude and motion representation, the combination of single rotation and space rotation is simple and convenient, the attitude is intuitive and the motion features are outstanding. In addition to the actual human head movement measurements and exercise simulation. Experiments show that the device can dynamically detect limb posture and speed and other motion information, and can quickly body posture simulation.
