Abstract

We are developing a system to confirm 3-D coordinate (X(t), Y(t), Z(t)) of golf ball flight trajectory by using video camera image. Information of tilt θ(t) and pan φ(t) angles of the camera are detected by two rotary encoder. The absolute distance r(t) from the camera to a golf ball will be detected in relation to the number of pixel area of a golf ball on the screen. Zooming mechanism is included in this system and some trials were conducted to include zooming mechanism.
