Human Motion Monitoring and Estimation based on Optical Measurement

Human motion monitoring is an important issue to study ergonomics and analyze the skill effect of human body under various equipment loads. In this paper, the joint angle of human motion is obtained by optical measurement technology, and then the amount of human motion is monitored and estimated. The system records and analyzes the changes of the main joint angles of the human body in walking, running, flexion and extension activities, and obtains the coordinates of bone points of various parts of the human body, and then estimates the amount of human motion using neural network algorithm. The experimental results of human motion monitoring show that the system can track and obtain the information of joint angles and bone points in the process of human motion, and can effectively estimate the amount of human motion.
