ABSTRACT:
A system for automatically recognizing persons or objects as they move past a selected location and for classifying the persons or objects in accordance with selected criteria. The system includes emitters for emitting beams toward a person or object moving past a selected location to generate reflected beams from the person or object. The included angle of the emitted and reflected beam is a function of the height of the person or object. A detector detects the reflected beams and generates signals representative of the included angle, and thus representative of a time-dependent height profile of the person or object from which the beams are reflected. The person or object is classified according to selected criteria.
