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

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

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

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

1: color image to grayscale, weighted average W = 0.229 × R + 0 587xg + 0114xb (1) Reduce the image to 1/4 of the source Image 2: Median Filter: required or not. Check the result. 3: binarization: high legal threshold 4: edge extraction: a simple first-order differential operation can be used, either horizontally or vertically, or a soble operator with a filtering effect. 5: Rough License Plate Extract

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

First, the preface This article mainly uses the YOLO V2 to train own license plate picture data, and can frame the license plate area which exists in the test picture, also is the license plate detection. This article refers to Bo
