Description: 摘要
车辆牌照识别(License Plate Recognition System, LPR)作为目标自动识别的一
种重要形式，可用于电子收费、出入控制、车流监控等众多场合，从而提高交通
管理自动化的程度，它的相关技术的研究正逐渐受到人们的重视。
本文主要介绍基于Run Length原理和Tamura纹理的车牌定位系统，该系统是基
于视频流进行开发的，主要包括车辆运动区域检测、车牌图像处理、车牌定位。
其中车辆运动区域检测利用多帧求平均的背景估计方法实现；车牌图像处理包括
灰度变换、中值滤波、边缘检测和二值化；车牌定位包括车牌水平定位、车牌垂
直定位、颜色判断和细定位。
该定位系统是在C++Builder环境下实现的，针对不同大小车牌、不同光照条件
的1400张图片进行测试，其定位率可以达到92 以上；同时也将该算法封装成DLL
库，应用在雷达测试仪中，对各种光照条件下的视频流进行测试。测试结果证明
本文算法简单、快速、准确率高，满足车牌识别系统实时性、通用性、和准确性
的要求，具有一定的应用价值。

As an important application form of target automatic recognition, vehicle license
plate recognition( LPR) technology is used in some fields, such as electron charging,
pass controlling and automobile stream supervising etc.
The paper introduces license plate location system based on the principle of Run
Length and Tamura texture feature. The system is developed based on video streams,
mainly includes vehicle motion region detection, license plate image processing, vehicle
license plate location. The detection of vehicle motion region uses the background
estimation methods based on the average of multi-frame license plate image processing
includes gray-scale transformation, median filtering, edge detection and binarization
the license plate location includes license plate horizontal location, license plate vertical
position, color judgments and accurate location.
The system is achieved in the C++ Builder environment, and it uses 1400 images
that are of different

Description: 计算机视觉是一门研究如何使机器“看”的科学，更进一步的说，就是是指用摄影机和电脑代替人眼对目标进行识别、跟踪和测量等机器视觉，并进一步做图形处理，用电脑处理成为更适合人眼观察或传送给仪器检测的图像。作为一个科学学科，计算机视觉研究相关的理论和技术，试图建立能够从图像或者多维数据中获取‘信息’的人工智能系统。这里所 指的信息指Shannon定义的，可以用来帮助做一个“决定”的信息。因为感知可以看作是从感官信号中提 取信息，所以计算机视觉也可以看作是研究如何使人工系统从图像或多维数据中“感知”的科学。
-Computer vision is a study of how to make the machine "see" the science, further said, that refers to the camera and computer instead of the human eye on the target identification, tracking and measurement machine vision, and further to do graphics processing, computer become more suitable for dealing with the human eye observation or detection of the image transmitted to the instrument. As a scientific discipline, computer vision research-related theory and technology, or trying to establish a multi-dimensional data from the image to get information artificial intelligence system. The information referred to here refers to Shannon defined, can be used to help make a "decision" of information. Because perception can be seen as extracting information from the sensory signal, so the computer can also be seen as a vision on how to make artificial systems or multi-dimensional image data from the "perception" of science.
