Paper Abstract

The system has been designed for instant sports replay. The passive unit utilizes two video cameras, an image processor, and a graphics computer to track the baseball pitch and provide an instant graphic replay of the pitch, showing the ball's trajectory, speed, and movement. Shown on the 1991 World Series, it has applications for both team training and game broadcasting as well as other sports.
