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:

LPR (License Plate Recognition) is an image-processing technology used to identify vehicles by their license plates. This technology is used in various security and traffic applications, such as the access-control system featured in the following animation. How License-Plate Readers Have Helped Police and Lenders Target the Poor. The website of a leading license-plate reader system claims its cameras can capture up to 1,800 license plates a minute during day or night, across four lanes of traffic and at speeds up to 150 miles per hour, alerting officers “within milliseconds” if a plate is suspect. Automatic number-plate recognition is a technology that uses optical character recognition on images to read vehicle registration plates to create vehicle location data. It can use existing closed-circuit television, road-rule enforcement cameras, or cameras specifically designed for the task. ANPR is used by police forces around the world for law enforcement purposes, including to check if a vehicle is registered or licensed. It is also used for electronic toll collection on pay-per-use roads a.
