Infra-red sensor system for intelligent vehicle highway systems

摘要

An infra-red sensor system for all weather, day and night traffic surveillance of ground based vehicles. The infra-red sensor system comprises system comprises an infra-red, focal plane array detector, signal processors, a communications interface and a central computer. The infra-red, focal plane array detector senses the heat emitted from vehicles passing within the field of view. Information collected from the array detector is input to signal processors which are programmed with tracking algorithms and other application specific algorithms to extract and calculate meaningful traffic data from the infra-red image captured by the array detector. The meaningful data includes the location, speed and acceleration of all vehicles passing within the field of view of the array detector. The information from the signal processors is transmitted to the central computer via the communications interface for further processing and dissemination of information.
