基于数学形态学的车牌定位方法

A Method of License Plate Location Based on Morphology

在汽车牌照识别系统中,车牌定位是整个识别模块实现的前提,目前车牌定位的方法多种多样,各有所长,但存在着计算量大或定位准确率不高等问题。文章结合数学形态学的基本运算,尝试使用数学形态学来实现车牌识别系统中的关键步骤——车牌定位。实验结果表明此方法算法简单,且有一定的定位准确率。

In car license plate recognition system, license plate location is the precondition of the whole recognition module. Now various methods are used in it, each of which has its own advantage. However, such problems as the quantity in calculation or the low correct location rate aren't solved. This paper uses mathematical morphology combined with its elemental calculation to realize the crucial procedure——license plate location in car license plate recognition. Experiment results show that such method can simplify the algorithm and has some correct location rate.
