AUTOMATIC TRACKING LIGHTING SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide an automatic tracking lighting system which automatically tracks a target for illumination and projects light. SOLUTION: A spotlight 1 is placed on a ceiling surface 13 free to rotate both horizontally and vertically, and a horizontal drive means 3a varies the horizontal angle of the spotlight 1 while a vertical drive means 3b varies the vertical angle of the spotlight 1. A CCD camera 4 photographs a target 8 for illumination in an illuminated space 9. An image recognition system 5 processes images of the CCD camera 4, identifies the target 8 for illumination, and specifies its coordinates. A coordinate computing device 6 computes the amount of movement of the spotlight 1 from the amount of movement of the target 8 for illumination. A movable control device 7 converts the result of computation by the coordinate computing device 6 into drive signals for the horizontal drive means 3a and the vertical drive means 3b and outputs the signals to the horizontal drive means 3a and the vertical drive means 3b to rotate the spotlight 1 in a desired direction.
