Abstract
With the rapid development of industrial countries in the world, increase the number of cars with the day, the city traffic conditions have become an increasing attention, effectively traffic management, has become a focal point of concern by more and more governments and relevant departments. How to make good use of existing transportation infrastructure and resources scientifically for the Chinese cities has become an effective means of transport for that matter, the development of intelligent transportation system (ITs) is a more appropriate solution. Intelligent Transportation Systems is the world's road traffic 2l century trends.
License plate recognition technology is a very wide range of applications of the technology. It is playing an increasingly important role in public safety in people's lives. Traffic management, and related military departments have an important application value. Vehicle license plate recognition technology is a specific target groups dedicated computer vision system, can automatically extract an image plate images, automatic segmentation of characters, and thus to identify characters. The technology of the vehicle collected image processing, in real time automatically and accurately identify the license plate numbers, letters and Chinese characters, and to direct the operation of the computer data to identify the results are given.
This study uses Hikvision DS-400HC/P card, this card has very high compression ratio, image quality, real-time video images to complete the compression, and won't dropped frames, It can finish the recognition of the completion of registration better, save the development time, but also improve the system performance to ensure the accuracy of license plate recognition.
In this paper, with the theory and practice of the context, have the depth research of the complexity of the license plate recognition system of the key technologies, and put forward new ideas and methods, license plate character recognition technology has great significance and application value.
