Intelligent Transportation Systems is the world's leading-edge transportation research, automatic license plate recognition systems in intelligent transportation system as an important technology, a combination of image processing, pattern recognition, a number of automation technology, now widely应用.
Car vehicle license plate is clear-cut and precise, the only sign. License plate recognition system can automatically determine the effective extraction plate and the image data and accurately identify the characters on the plate.
The system a complete license plate recognition. Include image preprocessing and character recognition in two parts. Image Pre-processing, first of all to have access to the license plate image using the histogram to enhance the principle of widening the contrast of images, making images appear more clearly, and then binary image processing to lay the foundation for follow-up; then Binarization image after the horizontal and vertical scanning to determine the exact location of license plates, and then based on a priori knowledge and the method of progressive scan and normalized partition plate characters; the last use of each character as a number of features extracted in order to character value identification. Character recognition part of the image after pre-treatment using a template matching method and BP neural network method comparison, came to the conclusion that the correct license plate characters

Intelligent transportation system is the world frontier of transportation research, the automatic identification system in intelligent transportation system as an important technology, combined with the image processing and pattern recognition, automation technology, now etc widely applied.
The car license plate is clear, accurate, the only sign. Vehicle plate recognition system can automatically judge effectively extract and the image data and accurate license plate recognition of the characters.
This system is put forward a complete vehicle plate recognition method. Mainly includes the image preprocessing and character recognition in two parts. Image preprocessing, to obtain the first vehicle images using the principle of image histograms enhancement of contrast, widening image appears more clearly, the binary image processing for the follow-up work foundation, Then in binary image on the horizontal and vertical scans determine the accurate location, then license to manufacture progre ive-scan prior knowledge and the method and the normalized character, Finally by using the method of extracting characters like several characteristic value in order to character recognition. In character recognition, the image preprocessing after using the template matching method and the BP neural network, and the correct character.本回答被网友采纳
