| 摘 要： | 车牌区域的颜色特征是车牌的重要信息.针对车牌区域颜色的伴生与互补特性,提出了一套在HSV空间利用颜色特征进行定位的算法.该算法利用车牌区域固定的颜色特征,快速定位到与车牌颜色有关的区域,然后利用车牌区域伴生与互补特性快速去除具有与车牌区域相同颜色的其他非车牌区域.最后使用投影积分进行车牌的精确定位.通过对200幅从交通卡口获取的真实的彩色图像进行试验,准确定位率为98%. |

| Abstract: | The color feature is an important information of the license plate,for this character the paper shows a method to locate the license plate using the concomitant and complementary color feature in the license plate region.The first,to locate all color regions similarly with the license plate.The second,to remove license body regions with similar color using concomitant and complementary color feature.At last,to locate the license plate accurately based on projection integral.The experiments on 200 automobile realistic RGB color images that are taken under various conditions from traffic stops show the accuracy of 98%. |
| Keywords: | vehicle license concomitant complement HSV space |
