Research on vehicle license location algorithm based on the characteristics of verge images

车牌定位技术是汽车牌照识别系统中的一项关键技术 .基于视频检测模块所捕获的车辆图像的成像特点 ,采用反锯齿的方法对其进行优化 ,并根据车牌的边缘特征 ,提出了一种基于边缘图像频率变化特征的二次车牌定位算法 ,用于车牌的定位和提取 .实验表明 ,该定位算法快速、准确 ,具有较强的鲁棒性 .

Vehicle license location technique is of critical importance to the vehicle license recognition system. This paper takes advantage of the method of counter-sawtooth to optimize the quality of the vehicle images which are captured by the video detection module and presents a 2-times license location algorithm with the use of the changing characteristic of verge images which is on the basis of the licenses′ verge characteristics. The location algorithm operates fast and accurately and are very robust through ...
