ABSTRACT:
A system for recognizing objects is comprised of: 1) a camera that has a lens which is uncovered; 2) a housing which encloses the camera, and has a window for the lens; 3) a rotating means, which is inside of the housing and which carries the camera, for receiving electronic control signals and rotating the camera at different angles in response thereto; and, 4) a control means for generating the electronic control signals such that the rotating means selectively points the camera lens -a) through the window at any one of several predetermined angles, and b) inside of the housing at the surface for calibrating the camera. With this system, the objects that are recognized can be human faces at different heights relative to the window in the housing. By pointing the camera lens inside of the housing, the lens is protected from damage even though it is not covered; and a calibration surface inside of the housing enables the camera to be calibrated while the lens is protected.
