▍Using opencv, C++ implementation of vehicle license plate recognition system. Vehicle license plate recognition system Places that need attention: VC++6.0 development tools, a simple SDI frame structure, once a bitmap (there is interested can make MDI) 1) data is bitmap information by a line from left to right, line by line to line up. 2) should be a multi. Automatic License Plate Recognition (ALPR) is a computer vision technology to extract the license number of vehicles from images. It is an embedded system which has numerous applications and challenges. Typical ALPR systems are implemented using proprietary technologies and hence are costly. How to implement automated license plate recognition in C# using OCR. This documentation is built up from two major parts: the first part consists of a rather theoretical and general description of license plate recognition and the Computer Vision technology in order to implement the example successfully; while the second part is a more detailed and programming- oriented documentation.
OpenALPR is an open source Automatic License Plate Recognition library written in C++ with bindings in C#, Java, Node.js, Go, and Python. The library analyzes images and video streams to identify license plates. The output is the text representation of any license plate characters.

User Guide
OpenALPR includes a command line utility. Simply typing 'alpr [image file path]' is enough to get started recognizing license plate images.
For example, the following output is created by analyzing this image:

OpenALPR requires the following additional libraries:
After cloning this GitHub repository, you should download and extract Tesseract and OpenCV source code into their own directories. Compile both libraries.
Please follow these detailed compilation guides for your respective operating system:
If all went well, there should be an executable named alpr along with libopenalpr-static.a and libopenalpr.so that can be linked into your project.

Contributions
Improvements to the OpenALPR library are always welcome. Please review the OpenALPR design description and get started.
Code contributions are not the only way to help out. Do you have a large library of license plate images? If so, please upload your data to the anonymous FTP located at upload.openalpr.com. Do you have time to 'tag' plate images in an input image or help in other ways? Please let everyone know by posting a note in the forum.

https://greatsydney875.weebly.com/stefanie-sun-my-desired-happiness-rar.html. Are there any freeware LPR (License plate recogniser) libraries or software in .net ?
Also can you list the freeware OCR libraries and software avaliable in .net ?

License Plate Recognition Source Code C Language Free
Check out emgu.cv. It's an open source wrapper for opencv, an open source image analysis tool. Here is an example on how to use it to detect license plates.
My experience is fairly positive as for this just working. It catches the main cases 90% of the time or so I'd say.
