Detailed Product Description: | The main task of Shenzhen City, as the Po is the vehicle license plate recognition system image analysis and processing under the intake to the complex background, positioning segmentation license, the last automatic recognition of characters on the license plate, license plate recognition only to identify the use of vehicle license and statistics vehicle, which is based on digital image processing, pattern recognition, computer vision and other technology-based intelligent recognition system. In the development of modern transportation intelligent recognition system is an important factor restricting intelligent transportation systems, modern identification system should be able to automatically extract the image from an image of the vehicle, automatic license plate image segmentation, the characters are correctly recognized, thereby reducing traffic management complexity. Vehicle intelligent image recognition system will get a series of processing, in the form of the output string, so that not only the small amount of data, easy to store, manipulate them more easily, and therefore ease identification system is manual identification can not be compared It bears great economic value and development space, research on identification technology is some sense. In recognition system technology is the most important of the two license plate location and license plate character recognition, these two technologies will directly affect the timeliness and accuracy of the entire recognition system. Many scholars at home and abroad on the license plate location technology a lot of research, but in practical applications are not yet a feasible and effective method, such as jitter caused because the vehicle license plate image skew, since stains and wear and tear caused by the license plate characters blur, blur due to the uneven illumination of license plate image, and this will more or less affect the accuracy of the license plate location for more than the actual situation, many scholars began to feature in the view of the license plate image itself on the basis of License plate location technology, and has put forward some effective positioning method to reduce the variety of primary, objective factors on the license plate positioning accuracy. However, the development of intelligent transportation makes the plates positioning system have a higher demand, mainly in the real-time performance and accuracy of the system. Substance license plate character recognition is Chinese characters, letters and numbers on the license plate quickly and accurately identify and output a string of recognition result character recognition technology is the key to the intelligent recognition system. Compared with other image recognition systems are much more complex in terms of, in character recognition, character recognition is also a critical part is the most difficult, because many foreign mature recognition system can not enter the Chinese market is that can not effectively recognize Chinese characters. Moreover, since the impact of the external environment, the system must be guaranteed under any weather conditions continuously throughout the day to work properly. To date with the former, in many automatic license plate recognition method it is not an ideal result can be achieved, so the significance of intelligent recognition technology major. License plate recognition system is the basis for the study of image processing technology. Design requirements and tasks are as follows: 1 Image Digitization: its purpose is to analog form by digital equipment image into discrete digital image data available to the computer. Image conversion 2: In order to achieve a purpose for the use of a mathematical technique image, after the image conversion more convenient, easy to handle and manipulate. 3 Image Enhancement: Image enhancement of the main objectives is to improve the quality of the image. The use of certain processing techniques to highlight certain information in the image, weaken or eliminate some irrelevant information, thus emphasizing the overall destination or local features, allowing the viewer to see more direct, clear analysis and image processing. Histogram correction, gray transformation, are commonly used means of strengthening the image profile and the like. 4 image segmentation: image research and applications, it is often interested only in certain parts of the image. They generally correspond to the image to be determined, the region with unique properties. Image segmentation is to a part of the image that needs to be segmented. 5 image analysis: analysis of the content of the image into feature extraction, image segmentation, symbol capture above, and detection and matching images. The basic principle of the license plate recognition system is: the camera captured images of the vehicle license contains input through the video card to your computer pretreated by the retrieval module A license to search, detect, locate, and segmented contain characters licenses rectangular area, and then the license binary characters and is divided into a single character, then the input digital JPEG or BMP format, the output is a license plate number. |
