Abstract

A people counting system with human information sensors for use in a multi-sensing application for detecting the number of persons and their directions of movement at a wide door has been developed. The sensor head module of this sensing system consists of a 1-dimensional 8-element detector array fabricated by a sheet forming method of pyroelectric PbTiO₃ ceramics, a IR-transparent lens and oscillating mechanical chopping parts. The sensor output is binarized by using the background mean method, and the number of passing persons and their directions of movement are recognized by a pattern recognition algorithm. By using this people counting system, the number of passersby at a 200 cm wide door can be detected with more than 95% accuracy
