Abstract

During the 2001 major league baseball season, the strike zone received special attention when officials decided to enforce the game's original definition, which made tracking pitches especially important. Tracking the flight of a pitch during a live broadcast presents two major challenges, however: speed and image-processing reliability.Meeting these challenges required developing a complex system that fuses high-end computer graphics with a sophisticated algorithm for calculating flight trajectories.ESPN's K Zone pitch-tracking system uses computer-generated graphics to create a shaded, translucent box that outlines the strike zone boundaries for viewers. Behind the flashy graphics, K Zone provides a sophisticated computing subsystem that monitors each pitch's trajectory. Its development model may well prove effective in future computer vision projects, regardless of the application domain.
