Moving vehicle specification system including an auxiliary specification function

摘要

A moving vehicle specification system having an auxiliary specification function. If a vehicle could not be specified by a local controller, the license plate number is decoded from a license plate image in a method where a number database is referenced according to grouped information and number information is retrieved. Auxiliary specification of the vehicle is performed through a comparison between the searched result and the decoded result. This prevents any impairment in the real-time performance of the processing based on local controller and permits more accurate vehicle specification.
