Title: Number plate reader
Inventor: HASEGAWA RIE
IPC: G08G1/017
Filed: 1990-02-08
Abstract: PURPOSE:To reduce obscurity and error of character recognition results by correcting the inclination of the picture of a number plate part in accordance with the inclination on the picture of the number plate and segmenting characters from the picture of the number plate part to recognize them. CONSTITUTION:Linear components are extracted in an area including left and right end areas of the number plate by a picture arithmetic processing part 7. Since the number plate is picked up as a parallelogrammic image by a camera 3, the inclination of the number plate on the picture is obtained by two obtained straight lines (plate frame). The picture of the number plate part is subjected to inclination correction processing based on the obtained inclination. Characters are segmented from the picture of the number plate part subjected to inclination correction, and the feature quantity of characters such as width W1 to W5 and height of characters is calculated. When characters are recognized based on the calculated feature quantity, the processing is simplified and obscurity and error of recognition are reduced because the inclination of the number plate of a vehicle is already corrected.
