基于matlab车牌识别系统的设计(论文11000字)
摘要：改革开放以来，随着社会的不断发展，人们的生活水平也在不断的提高，经济的发展在一方面导致了人们对汽车的需求量增多，而随着汽车需求量的增多，交通管理所面临的压力也在与日俱增，因此，交通管理怎样才能更好的运行引起了越来越多人的重视。当代社会科技水平的不断提升，尤其是在图像处理方面，很多利用这项技术的项目工程都取得了相当大程度的效率的提高，当然，在车牌识别系统中也是如此。在这个系统设计中，大致分为几个部分，分别是图像采集、图像预处理、车牌定位和分割以及字符的识别，整个过程是使用MATLAB软件设计的。
关键词：MATLAB、图像预处理、车牌定位分割、字符识别
 
License plate recognition system based on matlab
Abstract:Since the reform and opening up, with the continuous development of society, people's living standards are constantly improving, the development of the economy on the one hand led to people's demand for cars increased, and with the increase in demand for vehicles, traffic management is facing The pressure is also increasing, so how can traffic management better cause more and more people's attention. The continuous improvement of contemporary social science and technology, especially in the image processing, many of the use of this technology project has achieved a considerable degree of efficiency, of course, in the license plate recognition system is also true. In this system design, roughly divided into several parts, namely, image acquisition, image preprocessing, license plate positioning and segmentation and character recognition, the whole process is the use of MATLAB software design.
Keywords:MATLAB, The pretreatment of the image, License plate location segmentation, Character recognition
