摘要
人体运动的空间轨迹追踪是一种利用传感器技术和计算机技术来分析记录人体的运动过程的方法。为了实现人体运动轨迹的空间追踪,本文设计了一种人体可穿戴式的人体运动捕捉系统,通过佩戴在人体关节点的惯性传感器单元来获取肢体的实时姿态信息。惯性传感器由加速度传感器、角速度传感器和磁力计构成。通过微控制单元获取传感器数据,利用低通滤波和卡尔曼滤波来更新四元数,再将预处理后的数据由蓝牙模块实时发送到电脑端。本文通过对肢体运动的不同角度的实验,证明了利用惯性传感器可以追踪人体肢体、运动的空间轨迹。
Recognition of human motion can be achieved by tracking human motion trajectories by means of inertial sensors and computational technologies.In the paper,a novel human motion tracking system is designed using wearable inertial sensor units that are placed near the joints of the human body for real-time capturing of human posture information.Each inertial sensor consists of an accelerometer,agyroscope and a magnetometer.All inertial data are obtained through a microcontroller unit(MCU)and is preprocessed using a lowpass filter and a Kalman filter to update the Quaternion.The preprocessed data is transmitted to the computer via Bluetooth simultaneously.The experimental results prove the feasibility of using inertial sensors for real-time human body motion tracking.
