Description

Pursuiting algorithm of linear prediction and a color grade stressed integration for a flying baseball image is utilized to real-time measuremet of its trajectory. After the ball image of video screen on each TV monitor of stereo cameras is enhanced by cancelling background scene image in specified limited area, the true ball image is searched on the screen and their coordinates are located. In searching process, searching area on the TV screen area is limited within less than one thousandth of the TV screen area at the least, by using the linear prediction. Ball arriving point forecast algorithm on batter plane are experimentally demonstrated by using parabolic equation approximation, and forecast accuracy less than a few millimeters is estimated.
