机动车号牌

其次，根据机动车号牌字符的特点，抽取字符3种不同的特征，构造3个BP神经网络对机动车号牌字符进行识别。

Second , according to the characteristic of characters on the plate , we selected three different characteristics , and constructed three BP nerve nets ( NN ) to identify the characters on the motor vehicle plate .

通过分析实验结果，表明本算法在机动车号牌识别应用中达到了理想的识别效果。

According to the analysis based on the results of the experiments , it is demonstrated that the algorithm has a perfect identification effect .

首先，对机动车号牌图像进行大小、灰度方差、灰度均值的标准化处理。

First , we standardized the size , variance of gray scale and mean value of gray scale of the motor vehicle plate images .

如今，机动车号牌识别作为现代智能交通重要的一部分，已成为各级交通管理部门十分关注的科研课题之一。

As an important part of modern intelligent traffic , the recognition of vehicles'license plates has been one of scientific research subjects concerned by traffic manage department at all levels .
