Abstract

The present invention provides a license plates recognition system (400) for detecting and extracting multiple license plates. The system (400) acquires video sequences of the moving vehicles and processes the same to extract license plate registration number for matching. The system (400) utilizes FPGA having an edge detector (406) and a ROI based extractor (408) for determining the possible license plates and it position (or coordinate) thereof. The edge detections and ROI based extractions are carried out to process multiple images in parallel. The extracted license plate images are then processed by an OCR (412) to extract the registration numbers therein, and a search and alert module (414) is provided for search and matching (510) the license plate of interest. A method of processing the images to extract license plate is also provided.
