By utilizing high precision stereo- vision technology, flying articles such as baseballs are observed in real-time operation to find the lo- cus. The geometrical position of a moving base- ball is determined at every point using televi- sion images. Various characteristics such as speed and flying locus curvature are precisely analyzed, and the arrival point of the ball in the batter- plane can be forecast at every moment the ball is observed by television camera. This forecast can be utilized by a robot catcher who takes the place of a human catcher. A robot batter is also used instead of a human batter. These techniques are effectively utilized for the analysis of base- ball dynamics, player training and player evalu- ation. These techniques may also be applied to research in other sports as well as other physical phenomenons.
