Test results at 20 real intersections show that the ratio of correct stabling siding recognition reaches up to 90%; and the ratios of recognition of traffic lights and divided characters are 85% and 97%, respectively.

通过20个实际交叉口场景测试数据验证，采用所提出的方法，停车线检测正确率达90%，信号灯检测正确率为85%，在信号灯字符正确分割出来的基础上，字符的识别率达97%。

This dissertation brings forward and realizes the multilevel classifiable method which is based on characters coding. Above all, this method realizes the first-grade classification by extracting enough effective characters from characters and coding them, to the others which couldn't be recognized by the first-grade classification, the method will adopt the second-grade classification using template matching to recognize these characters.

本文使用了基于特征编码的多级分类识别方法，通过给字符抽取足够多的有效的特征并给特征编码实现第一级分类，对于第一级分类后仍不能区分的字符，再进入第二级分类用模板匹配的方法最终达到区分的目的，这种方法的重点在第一级分类阶段。
