Raspberry Pi Automatic License Plate Recognition with Open. CV 5 : Open. ALPR on your Raspberry Pi. In this tutorial I show how to use the Open. ALPR, (Open Automatic License Plate Recognition) on your Raspberry Pi. Automatic License Plate Recognition using Python and OpenCV K.M. Sajjad Department of Computer Science and Engineering M.E.S. College of Engineering, Kuttippuram, Kerala [email protected] Abstract—Automatic License Plate. EDIT: I wrote a Python script for this. As your objective is blurring (for privacy protection), you basically need a high recall detector as a first step. Here's how to go about doing this. The included code hints use OpenCV. I go over the download, installation, build, and compilation, on your Raspberry Pi. From your desktop and then transfer it to the pi================================================go to this page and download it: http: //www. Downloads/tesseract- ocr- 3. Downloads/leptonica- 1. Downloads/openalpr. From the pi: ===========wget http: //www. I used 1. 2. 0. 4 to be safe with rpihttp: //www. Dependencies=================================================sudo apt- get install autoconf automake libtoolsudo apt- get install libpng. First Leptonica, because Tesseract needs Leptonica in order to work===================================================================gunzip leptonica- 1. Second Tesseract: =================gunzip tesseract- ocr- 3. TESSDATA. It is free software, released under the Apache License, Version 2.
A few examples of OCR applications are listed here. The most common for use OCR is the first. Item, people often wish to convert text documents to some sort of digital representation. People wish to scan in a document and have. Google since 2. 00. Tesseract is considered one of the most accurate open source OCR engines currently available. The Tesseract engine was originally developed as proprietary software at Hewlett Packard labs in Bristol, England and Greeley, Colorado between 1. Windows, and some migration from C to C++ in 1. A lot of the code was written in C, and then some more was written in C++. Since then all the code has been converted to at least compile with a C++ compiler. Very little work was done in the following decade. It was then released as open source in 2. Hewlett Packard and the University of Nevada, Las Vegas (UNLV). Tesseract development has been sponsored by Google since 2. Open. CV was built to provide a common infrastructure for computer vision applications and to accelerate the use of machine perception in the commercial products. Being a BSD- licensed product, Open. CV makes it easy for businesses to utilize and modify the code. The library has more than 2. These algorithms can be used to detect and recognize faces, identify objects, classify human actions in videos, track camera movements, track moving objects, extract 3. D models of objects, produce 3. D point clouds from stereo cameras, stitch images together to produce a high resolution image of an entire scene, find similar images from an image database, remove red eyes from images taken using flash, follow eye movements, recognize scenery and establish markers to overlay it with augmented reality, etc. Open. CV has more than 4. The library is used extensively in companies, research groups and by governmental bodies. Cesco. 34. 5git: https: //github.
