能够检测到受监控路面的车辆并自动提取车辆牌照信息（含汉字字符、英文字母、阿拉伯数字及号牌颜色）进行处理的技术。车牌识别是现代智能交通系统中的重要组成部分之一，应用十分广泛。它以数字图像处理、模式识别、计算机视觉等技术为基础，对摄像机所拍摄的车辆图像或者视频序列进行分析，得到每一辆汽车唯一的车牌号码，从而完成识别过程。通过一些后续处理手段可以实现停车场收费管理，交通流量控制指标测量，车辆定位，汽车防盗，高速公路超速自动化监管、闯红灯电子警察、公路收费站等等功能。-Monitored to detect the vehicles on the road and automatically extract vehicle license information (including Chinese characters, English letters, Arabic numerals and number plate color) processing technology. LPR is a modern intelligent transportation system, an important part of one widely used. It is a digital image processing, pattern recognition, computer vision technology, the camera captured images or video sequences vehicle analysis, only every car license plate number, thus completing the identification process. By means of some post-processing can be achieved parking fee management, traffic control index measurements, vehicle location, vehicle anti-theft, highway speeding automated monitoring red light electronic police, highway toll stations, etc. functions.
