- Abstract
In order to solve the problem of license plate recognition in a complex environment, put forward a combined with the feature of license plate color, gray features, geometric shape, a general method of license plate recognition, first of all according to the color feature of license plate of China, this paper proposes a method based on HSV color space color recognition of license plate, solves the basic problem of license plate recognition accuracy is not high; Then with the improved Sobel operator edge detection method to obtain a rectangular area where the background plate; Finally could license plate area unified dimension, and verification, the last segment the license plate area. Adopt natural complex images taken to validate the new method in the environment of experiments show that compared with other methods, the new method can be adaptive within limits the type of license plate number, size, and direction, and the car position in the image and image background of fewer restrictions, applicability is a strong way.
