Paper Abstract

In this paper, we described a real-time measurement technique for analyzing flying ping-pong ball movement. A high picking rate CCD camera was selected, and the ping-pong ball was marked with two different colors. A fast algorithm which applied dynamic windows to determine the position of object was introduced. Through position-finding of mass center, measurement of the highest linear speed 40m/s can be obtained. Technique of FFT processes video images of marks on a ping-pang ball to get rotational speed. The highest rotatory speed of this measurement can reaches 200 r/s. The preliminary experimental results were obtained and its performance coincided with the theory. Relative error of this system was better than 5%.
