License plate recognition has become one of the key work of traffic vehicle management, at present, mobile license plate recognition in China's police service, parking lot handheld charging machine, such as mobile terminal use more widely, if in these terminals can integrate licens
I have been busy with R D tasks in the past year and have to move on to Silverlight 3D learning. In R D, image recognition of license plates, number of heavy vehicles and bridges (mainly used for overload detection), and image recognition of some mining seeds are required. This section describes image recognition for license plates.
In fact, the license
cutting on a vertical projectionFirst, I choose the license plate number as a projection of the picture, can be used as a license plate cutting technology. Principle: After the license plate is processed, all pixel values are stor
With the rise of intelligent parking system, license plate recognition technology is really a fire. I'm here, too. Interest, a general view of the current situation, found that the current popular license plate recognition technology is based on neural networks (see Mastering OpenCV with practical computer Vision proje

This article refers to the automatic license plate recognition project in the deep understanding of OPENCV practical Computer Vision Project analysis, and then carries on the practice after understanding the method. The difficulty of accurately identifying the sequence of the characters in the
At present, mobile license plate recognition in China's police service, parking lot handheld charging machine, such as mobile terminals of the use of more popular, if in these terminals can integrate license plate recognition function, for the maintenance of traffic safety and urban security, the realization of traffic
Advantages of the Mobile license plate recognition OCR system:1. Fast recognition Speed: Highly optimized license plate location and recognition algorithm, the recognition time ≤ milliseconds ( million pictures ). 2, recognition rate: Daytime recognition rate ≥99.7%; Night recognition rate ≥98%. 3, recognition Speed: S
Here is the lpr of a few articles on the previous project some of the relevant information, involved in the laboratory internal information is not put up, I hope to understand this aspect of the students, some help, it is afraid to know a probably better. It's good to know the whole idea. At the beginning is a person blind groping, go a lot of detours, also calculate to other people a little advice.License Plate Recognition LPR System series article S

License plate numberTime limit: Ms | Memory limit: 65535 KB Difficulty: 1 description Yan Yan very like to study the license plate number, from the license plate number can see the number registration sooner or later, according to
The process of License Plate Recognition can be divided into three steps: License Plate positioning, character segmentation, and character recognition.
You can perform the following steps to create a subdivision:
(1) grayscale and binarization Images
(2) remove noise and cut it into one character
(3) extract features o
License plate number identification based on opencv _ 2, opencv_2Introduction
The previous article explains how to screen images in blue and then perform grayscale/binarization. Here we will continue to explain.
Rectangle Detection
Because the license plate is a rectangle. So we will expand the image after the binariza
OpenALPR can be used as a License Plate Recognition System.GuideNetwork monitoring cameras have now become one of the most important security tools, but you may not have time to view what the cameras have captured, so that their functions will not be so great. There is an open-source software library called OpenALPR (Automatic License
The mobile license plate recognition technology is an image recognition technology developed on the basis of OCR optical character recognition technology, which is used to identify the feature information of automobile number plates. At home, the technology by the Beijing Yi-Bo era and Tsinghua University successfully to "National 863 Plan" project results-"Text image recognition technology TH-OCR" industri
Travel essentials vehicles In the convenience of people to travel at the same time, resulting in a significant increase in vehicle management problems:The number of cars and the development of vehicle managers over time form a big loophole. Thus with the license plate Recognition SDK to help the electronic eye, mobile Police, site survey and other activities, reduce staff pressure.What is the difference bet
This article comes from a simple license plate recognition system that I spent 2 days ago. The project, the time is too tight, the sample is also limited, can not reach the request of the other 95% recognition rate (mainly for the license plate, d,0,o,i,1, etc. too similar.) Then, the recognition of Chinese characters
