Abstract
This invention identifies vehicles on arrival, and matches exiting vehicles to their corresponding entry event. The system uses at least one camera to capture not only the vehicle license plate but also the visual features. A 'signature' formed out of the optical features of the vehicle is compared against the pre-generated signatures of vehicles in a whitelist. The “signature” for each exiting vehicle is compared against all signatures of vehicles that entered the garage. A plurality of filters reduce the possible matching candidates based on factors like license plate based edit distance, location information of vehicle owner. Synchronizing a database in each local processing unit (LPU) with a central database enables signature from images from sites that have good license plate reads, to assist in authentication in other sites where the reads are lower quality. Spatial diversity in cameras and/or illuminators enable hologram and 3D Printing detection and decoding.
