基于车牌识别的高速公路网多路径精确识别研究
发布时间：2019-01-01 09:22
【摘要】：随着中国高速公路的不断发展，许多城市的高速公路都具有了网状的结构，，从一个地方到另一个地方的公路有很多条，高速公路的相关管理部门开始对线路确认模糊的现状进行研究，因为线路确认模糊会造成车辆通行费用的不确定性等情况。在高速公路上，车辆的通行费用是以行驶距离来计算的，如果公路上存在网状结构或者环形结构，不同收费站之间就会有多条路径，从而导致了车辆通行费用的差异较大。所以，如何确定最终的通行路线，是提高当前高速公路收费准确度的一个重要问题。 本文首先就通行路线对费用的影响进行了分析，研究了各种通行路线判断方法的原理、不同判断方法的优缺点和影响通行路线判断方法的各种实际因素；然后重点研究了以车牌号识别为基础的高速公路通行路线的准确判断方法，对其中的关键原理与技术进行了分析研究，实现了车牌识别(VLPR)系统在车辆通行路线判断中的应用；最后，在VLPR系统的基础上，给出了车辆通行路线判断问题的最优解决方案，并仔细研究了系统的构架和网络传输，统筹设计了数据库和相关软件，结合陕西正在进行的高速公路收费系统工程，本研究结果与工程实际形成互动契约，现行工程取得了良好社会效益。
[Abstract]:With the continuous development of China's highways, many urban freeways have a network structure. There are many highways from one place to another. The relevant management departments of freeway begin to study the status quo of line confirmation fuzzy, because the fuzzy line confirmation will lead to the uncertainty of vehicle passage cost and so on. On the freeway, the passage cost of the vehicle is calculated by the distance. If there is a network structure or ring structure on the highway, there will be many paths between different toll stations, which leads to the great difference of the vehicle tolls. Therefore, how to determine the final route, is an important issue to improve the current highway toll accuracy. Firstly, this paper analyzes the influence of the route on the cost, studies the principle of the different ways of judging the route, the advantages and disadvantages of the different methods, and the practical factors that affect the judgment of the route. Then, the accurate judgment method of expressway route based on vehicle license plate recognition is studied, and the key principle and technology are analyzed and studied. The application of license plate recognition (VLPR) system in vehicle routing judgment is realized. Finally, on the basis of VLPR system, the optimal solution to the problem of vehicle routing judgment is given, and the structure of the system and network transmission are carefully studied, and the database and related software are designed as a whole. Combined with the highway toll system project in Shaanxi province, the result of this study forms an interactive contract with the engineering practice, and the current project has achieved good social benefits.
