OpenALPR is an automatic number-plate recognition library written in C++. The software is distributed in both a commercial and open source version.

History

OpenALPR was originally developed by a two-man team led by Matt Hill.[1] The open source software became available as a free download at the end of 2015.[4] In March 2016, OpenALPR launched paid Cloud API service[5] and in February 2017 introduced the OpenALPR agent for Axis Communications cameras.[6]

In August 2017 an Australian web developer Tait Brown became known by creating an alternative to an 86 million AUD project of Victoria Police by using OpenALPR.[7] In March 2018 ProgrammableWeb added OpenALPR to its list of Recognition APIs.[8]

Software

OpenALPR is an automatic number-plate recognition library written in C++.[9] The software is distributed in both a commercial cloud based version[1] and open source version.[3][10] OpenALPR makes use of OpenCV and Tesseract OCR libraries. It could be run as a command-line utility, standalone library, or background process. The software also integrates with video management systems (VMS) such as Milestone XProtect.[11]
