摘　　要：车牌识别在智能交通系统中起着重要作用,车牌定位是车牌识别中的关键步骤,目前车牌定位的方法多种多样,各有所长,但是存在着计算量大或定位准确度不高等问题.尝试使用梯度投影与彩色区域分割相结合的方法来实现车牌识别系统中的关键步骤——车牌定位.实验结果表明此方法算法简单、准确率高、实时性好,能够满足实际车辆车牌自动识别系统应用的需要.Automatic License Plate Recognition (LPR) plays an important role in Intelligent Transportation System. However license plate location is a key component of the LPR system. Nowadays various methods are used in it, each of which has its own advantage. However, such problems as the quantity in calculation or the low correct location rate aren’t solved. This paper uses a license plate location method based on gradient projection and color area segmentation to realize the crucial procedure—license plate recogni...
