高速公路有光盘遮盖车牌识别系统研究

Research on recognition of car license plate covered with CD

针对光盘遮盖时车牌不易识别的问题,提出了一种新的字符分割的方法.该方法先计算行列像素,再与设定阈值进行比较以判断字符的开始和结束位置.实验结果表明,所提出的识别系统识别率较高,正确率达到90%以上.

Aiming at the difficulty in car license plate recognition covered by CD, a new image segmentation method was proposed. The method calculated the ranks of pixels, compared with the set threshold value to determine the beginning and end of the character. Experimental results showed that the proposed recognition system had high recognition rate and accurate rate is above 90%.
