| 摘 要： | 本文介绍行驶车辆牌照自动识别系统,利用CCD工业电视摄像机不断获取运动车辆的正面车头图象、实时地送入计算机,然后根据图象的纹理结构,从图象背景中分离出牌照,再应用模式识别技术对牌照上的汉字省名和数字进行识别,并针对动态图象的模糊,牌照底色灰度不一,牌照可能被污染、畸变等现象提出了解决方法。

| Abstract: | An automatic on-line vehicle number plate recognition system is developed
which is used for traffic surveillance and management. The features of the
system are as follows: (a) a series of scenes are obtained into the system auto-
matically by CCD industrial camera and frozen by an external infrared ray sen-
sor detecting vehicle; (b) A texture analysis method is used for extracting nu-
mber plates from vehicle images; (c) Overlap-class method and dynamic progra-
mming technique are used to recognize Chinese characters, and Arabic numerals
are recognized by their topalog characteristics. Experiment results show that the
developed methods are efrective and satisfactory. |
