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.
In particular, a license plate identification technology for the target object special computer vision system, from a picture can automatically extract the image segmentation, and character, and character recognition. This technology to automobile collected on image processing, can be accurately identify real plate number, letters and Chinese characters, and can be directly to the computer operation data form identification results.
This study uses Hikvision DS-4004HC/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.
Aiming at the plate intelligent identification system, the key technology for adopting new ideas and methods of plate character recognition technology, the research has great significance and application value.
