ABSTRACT:
A system for automatically counting people as they move past a selected location, and for measuring their heights. The system includes emitters for emitting beams toward persons moving past a selected location to generate reflected beams from the person, such that the included angle of the emitted and reflected beams is a function of the person's height. A detector detects the reflected beams and generates signals representative of the included angle, and thus representative of the height of the person. The signals representative of the height of the person are converted to data that may be used for evaluation purposes. The system is particularly adaptable for use in retail stores for determining the number of shopper units in the store during selected time periods and evaluating store performance based, in part, on the conversion of shopper units to actual customers.
