摘要
基于肉眼识别车辆车牌并用手工输入更改车辆状态,已经不能满足当前的车辆管理信息系统的需要。采用基于图像处理,模式识别的车牌自动识别技术(License Plate Recognition,LPR),通过对采集的含有车牌的图像进行预处理,车牌定位,车牌分割、识别,并将识别结果应用于车辆管理信息系统。LPR技术与车辆管理信息系统的结合,避免了车牌因天气、光线、污损等造成不能100%正确识别的弊端,大大的提高了车辆出场回场环节的效率。
The way of identifying license plates by visual recognition can no longer meet the need of modern Vehicle Management Information System.Based on image processing,pattern recognition,license plate recognition technology(License Plate Recognition,LPR),through collecting,pre-processing,locating license plate,segmentating license plate,recognizing the photo which contains license plate and provding the result to our Vehicle Management Information System.The combination of Vehicle Management Information System and LPR,avoid the affect from weather,ligth,defaced which makes the 100% correct identification of license plates very difficult.The system efficiency is greatly increased.
