LPR(Vehicle License Plate Recognition)

前言

这是一个车牌识别的实例

我的平台是vs2017和opencv3.4

opencv下载链接点这里

写这个是因为实验课布置了一个车牌识别的作业, 但是网上车牌识别的教程都很复杂,也没有太实际。 对于完全没有接触过的人,完全是一头雾水。 所以我在摸索了一个星期后,终于把这个车牌识别了出来, 希望给新手一个指导,怎么一步步地实现一个简单的车牌识别。 (暂时写个大概,有时间后继续完善!觉得有用的话可以给我一个star)


任务:识别下图中的车牌

car

要实现车牌识别,一共分为两大步。
第一,车牌定位,就是在图片中确定出车牌的位置;
第二,字符识别,将提取出来的字符图片进行识别。
