Algorithm Research & System Implementation of Automatic License Plate Recognition

Abstract

自动车牌识别(ALPR:AutomaticLicensePlateRecognition)指从数字图像中自动寻找到车牌位置并识别出车牌内容的技术,即把包含有车牌的数字图像转换为车牌的ACSII字符串。自动车牌识别技术是计算机技术的综合应用领域,也是智能交通系统的重要基础技术,具有重要的理论研究意义和实用价值,是学术界和产业界的共同研究热点。然而,自动车牌识别技术的可能应用场景往往是对公路上运动车辆进行实时现场识别,而且要求适应全天候室外工作环境,所获取的实时动态图像序列背景复杂、光源多样、强度多变、车牌类型多种,车牌图像可能出现模糊、污染、遮挡、倾斜、缺损等,已有的自动车牌识别技术都存在若干难...Automatic License Plate Recognition (ALPR) is a kind of technology which locates a license plate in a digital image and recognizes the characters of it automatically. It means a translation from a license plate image to an ACSII string. ALPR is an integrative application field of computer technology. As the basic technology of ITS (intelligent transportation systems), it is significant for theore...学位:工程硕士院系专业:计算机与信息工程学院计算机科学系_计算机应用技术学号:20022802
