Is opencv open source?

Yes ,OpenCV It's based on BSD The license ( Open source ) Released cross platform computer vision and machine learning software library , Can run in Linux、Windows、Android and Mac OS On the operating system . It's lightweight and efficient —— By a series of C Functions and small quantities C++ Class a , It also provides Python、Ruby、MATLAB Language interface , Many general algorithms in image processing and computer vision are realized .

OpenCV use C++ Language writing , It has C ++,Python,Java and MATLAB Interface , And support Windows,Linux,Android and Mac OS,OpenCV Mainly for real-time visual applications , And use when available MMX and SSE Instructions , Now it's also available for C#、Ch、Ruby,GO Support for .

opencv What's the usage? ?

Most computer scientists and practical programmers know some of the roles of computer vision , But few people know all the ways of using computer vision . for example , Most people know its use in monitoring , Many people also know that it is increasingly used for images and videos on the Internet . However , Fewer and fewer people are aware that most aerial and street map images use camera calibration and image mosaic techniques . Some people realize that in security monitoring , Unmanned aerial vehicles or applications in biomedical analysis . But few people know how popular machine vision is in the manufacturing industry ： Almost all mass-produced products have been automatically detected by computer vision . OpenCV The structure of the open source license allows you to use all or part of OpenCV Building commercial products .OpenCV It is very popular all over the world , In China, , Japan , Russia , Europe and Israel have a large user base . since 1999 year 1 Published in alpha Since Edition ,OpenCV It has been used in many applications , Product and research work . These applications include satellite and network maps , Image scan alignment , Medical image denoising , Object analysis , Security and intrusion detection systems , Automatic monitoring and safety system , Manufacturing inspection system , Camera calibration , Mosaic images in military applications and unmanned antennas , Ground and underwater vehicles . It is even used for sound and music recognition .
