Recognition Processing Device for Automobile License Plate Using Multi-Mask Technique and Its Method

摘要

A vehicle detection unit which detects the presence of a vehicle and converts it into an electrical signal and outputs the electric signal; a camera unit which generates and outputs image data of the vehicle by photographing the vehicle when the vehicle is detected; and detecting the vehicle. When the vehicle is detected by the unit, the image data input from the camera unit is read, the search is started from the line with the highest probability among the image data, differential processing and filtering are performed, and the edge is extracted. After retrieving the numerical domain by using the adaptive binarization and labeling for each domain, the character and the numerical domain are extracted, and the character and the character are extracted using multiple masks and input into the neural network to recognize the characters and numbers. A control unit and a memory in which programs and data are stored, and a neural network As used in the character recognition, using a multi-mask provides misrecognized causing the suspicious region by giving a weight added by the multi-mask techniques that improve the recognition rate of the license plate recognition processing apparatus for and method.
