A Prototype of Technique Training System for Human Motion (swing)

We constructed a prototype of technique training system for the human swing motion in the present paper. The swing motion of golf is captured by two highspeed video cameras, which is capable of taking pictures every 1 millisecond at the resolution of 512x512 pixels. Images taken by two cameras were synchronized and the data points on the human body were collected in 3D. The 3D swing motion was dynamically analyzed and put into as initial values to an optimizing calculation. By comparing the actual and the optimized motions, we diagnosed the efficiency of the subject's swing technique. We showed the validity of our system, and were able to advise how the subjects can improve their swing motion.
