摘要
车牌的颜色特征是车牌定位的一个关键信息。复杂背景下,直接对车牌边缘进行分割以达到车牌的定位比较困难。为解决上述问题,提出了一种复杂背景下基于颜色的车牌定位方法。此方法通过颜色空间变换,将复杂背景下与车牌颜色相近的颜色全部保留,滤除其他不符颜色。实验结果表明,基于颜色的车牌定位方法,去除了背景颜色及不相干区域的干扰,可以简化后续车牌处理算法,提高车牌定位的精度和速度。
The color feature of vehicle license plate is the key information of vehicle license plate location. Under complex background, it is difficult to locate the license plate by separating the license plate edge directly. In order to solve the above problem, a color-based vehicle license plate location method under complex background is proposed. The color space transforma- tion is used to reserve the color similar to the vehicle license plate color under complex background, and filter out other un- matched colors. The experimental results show that the color-based vehicle license plate location method can eliminate the back- ground color and interference in incoherent area, simplify the subsequent vehicle license plate processing algorithm, and im- prove the vehicle license plate positioning accuracy and speed.
