| 摘 要： | 针对复杂背景下的车牌定位问题,提出了一种基于字符边缘颜色与逻辑的快速车牌定位方法。该定位方法将RGB彩色空间中的车牌图像,转换到HSV彩色空间中。根据像素点颜色进行二值化,得字符边缘颜色像素区,同时通过逻辑与,确定图像字符颜色边缘点,最后经纹理分析来定位车牌,解决了目前常用流行算法所不能处理的定位问题。 |
| 关 键 词： | 车牌 字符边缘颜色变化特征 与逻辑 纹理分析 定位 |

| Abstract: | Aiming to the location of vehicle license plate in complex circumstance，this paper presents a fast plate location method which utilizes logic AND operation to character edge color.It converts the plate image in RGB color spaces into HSV color spaces，and by binarization each pixel’s color to acquire character edge color area，then by their logic AND operation to get the image’s character color edge，at last by texture analysis to locate the plate，so it can solve the problem of popular location methods in common use. |
| Keywords: | vehicle license plate character edge color variation feature logical AND operation texture analysis location |
