Perimeter Image Capture and Recognition System

摘要

Provided is a system and method of electronically identifying a vehicle entering/leaving a predetermined geographical area by identifying a license plate and comparing the results to a predetermined database. The software aspect of the system runs on standard PC hardware and can be linked to other applications or databases. It first uses a series of image manipulation techniques to detect, normalize and enhance the image of the number plate. Optical character recognition (OCR) is used to extract the alpha-numeric characters of the license plate. The recognized characters are then compared to databases containing information about the vehicle and/or owner.

主权项

1. A non-transitory computer readable medium having computer executable instructions for performing a method comprising:
a. a computer for executing said instructions; b. maintaining a database of predetermined identification values; c. capturing an image of a vehicle traveling in a predetermined geographical are from at least one of a plurality of imaging devices in communication the computer; d. projecting a plurality of polygons onto the captured image; e. capturing at least one polygon projected on the captured image responsive to the detection of the presence of alpha-numeric characters within the at least one of the plurality of polygons projected onto the captured image; f. establishing a recognition value derived from the alpha-numeric characters within the at least one detected polygon; g. storing the recognition value; comparing the recognition value to the predetermined identification values; h. creating an alert responsive to a match between the recognition value and a value in the database of predetermined identification values; and i. communicating the alert to at least one recipient.
