What are the ways to realize license plate recognition
识别步骤概括为：车牌定位、车牌提取、字符识别。三个步骤地识别工作相辅相成，各自的有效率都较高，整体的识别率才会提高。识别速度的快慢取决于字符识别，字符的识别目前的主要应用技术为比对识别样本库，即将所有的字符粪池模具 路缘石模具 唐山通风管道 塑钢电缆挂钩 钢纤维 钢制拍门 植绒机 铜雕佛像建立样本库，字符提取后通过比对样本库实现字符的判断，识别过程中将产生可信度、倾斜度等中间结果值；另一种是基于字符结构知识的字符识别技术，更加有效的提高识别速率和准确率，适应性较强。
The recognition steps are summarized as follows: license plate location,
license plate extraction and character recognition. The three steps of
identification work complement each other, and their respective
efficiency is high, so the overall recognition rate will be improved.
The speed of recognition depends on character recognition. At present,
the main application technology of character recognition is the
comparison and recognition sample library, that is, all characters
establish the sample library, and the character judgment is realized
through the comparison sample library after character extraction.
Intermediate result values such as reliability and inclination will be
generated in the recognition process; The other is character recognition
technology based on character structure knowledge, which can more
effectively improve the recognition rate and accuracy, and has strong
