LICENSE PLATE MATCHING SYSTEMS AND METHODS
First Claim
1. A system for license plate matching comprising:
- a system interface configured to receive roadside data from a remote device, the roadside data including at least a roadside image of a first vehicle license plate;
a database having a plurality of indexed entries, each entry of the plurality of entries including at least vehicle license plate fingerprint data and vehicle characteristic metadata; and
at least one processor operatively connected to a memory, the system interface, and the database, the processor when executing configured to;
execute a query against the database based on the roadside data,compare at least a portion of the entries to the roadside data, the processor when executing being further configured to compare the roadside image of the first vehicle license plate and at least the corresponding vehicle license plate fingerprint data when comparing the portion of the entries and the roadside data, andgenerate a confidence factor based in part on a degree of similarity between at least one individual entry of the portion of the entries and the roadside data.

Abstract
Systems and methods for license plate matching. In one example, a system for license plate matching includes an interface configured to receive roadside data, the roadside data including a roadside image of a vehicle license plate, a database having a plurality of indexed entries, each entry including vehicle license plate fingerprint data and vehicle characteristic metadata, and a processor connected to a memory, the interface, and the database, the processor configured to execute a query against the database based on the roadside data, compare a portion of the entries to the roadside data, the processor being further configured to compare the roadside image of the vehicle license plate and the corresponding vehicle license plate fingerprint data when comparing the portion of the entries and roadside data, and generate a confidence based on a similarity between at least one individual entry of the portion of entries and the roadside data.

13. A method for license plate matching, the method comprising:
-
receiving roadside data including at least a roadside image of a first vehicle license plate; querying a database having a plurality of indexed entries, each entry of the plurality of entries within the database including at least vehicle license plate fingerprint data and vehicle characteristic metadata; comparing at least a portion of the entries to the roadside data, including comparing the roadside image of the first vehicle license plate and at least the corresponding vehicle license plate fingerprint data; and generating a confidence factor based in part on a level of similarity between at least one individual entry of the portion of the entries and the roadside data. - View Dependent Claims (14, 15, 16, 17, 18, 19)

20. A method for vehicle license plate indexing, the method comprising:
-
receiving vehicle license plate metadata; dynamically generating a composite image of a virtual vehicle license plate based on the received vehicle license plate metadata; generating vehicle license plate fingerprint data, the vehicle license plate fingerprint data including image data extracted from the composite image; and generating an indexed entry for a vehicle license plate matching system database based at least in part on the vehicle license plate fingerprint data.
