Abstract
Abstract 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.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
153 words
A moving vehicle specification system comprising: communication means for performing radio reception, from vehicles moving on a road having a plurality of lanes, of identification information unique to each of the vehicles; vehicle detection means for generating vehicle detection information by separately detecting vehicles that have passed predetermined positions on the road; specification means for specifying said vehicles by correlating the vehicle detection information with the identification information; a number database for storing a correlation of number information inscribed on the license plates of the vehicles with the identification information of corresponding vehicles; and auxiliary specifying means for, by referencing said number database with the identification information and by comparing the results thereof with license number images obtained from photographs of said predetermined positions or their vicinity, correlating the vehicle detection information and/or the identification information with the number information, and furthermore specifying vehicles that at least the specification means failed to specify.
Claim 2
Dependent Claim
153 words
A moving vehicle specification system comprising: communication means for performing radio reception, from vehicles moving on a road having a plurality of lanes, of identification information unique to each of the vehicles; vehicle detection means for generating vehicle detection information by separately detecting vehicles that have passed predetermined positions on the road; specification means for specifying said vehicles by correlating the vehicle detection information with the identification information; a number database for storing a correlation of number information inscribed on the license plates of the vehicles with the identification information of corresponding vehicles; and auxiliary specifying means for, by referencing said number database with the identification information and by comparing the results thereof with license number images obtained from photographs of said predetermined positions or their vicinity, correlating the vehicle detection information and/or the identification information with the number information, and furthermore specifying vehicles that at least the specification means failed to specify.
Claim 3
Dependent Claim
78 words
A vehicle specification system according to claim 1, further comprising: local controllers, arranged at a plurality of locations along said road, each including said communication means, vehicle detection means and specifying means; and a host controller, having said number database and said auxiliary specifying means, for inputting specifying results by specifying means, vehicle detection information and identification information for which the corresponding specifying means failed at correlation, and said license number images from a plurality of local controllers.
Claim 4
Dependent Claim
56 words
A vehicle specification system according to claim 1, wherein said communication means, by performing radio communications regarding at least debiting with said moving vehicles, performs radio reception from vehicles of identification information unique to the vehicles; and said vehicle specifying system is an automatic debiting system for automatic debiting against said vehicles and detecting illegal vehicles.
