Introduction to OpenCV

What is OpenCV? Its full name is Open source Computer Vision Library, an open source computer vision library. As shown in the picture above, what we see is the OpenCV logo. We can see three small circles made of distinct R, G, and B colors. Composition, that is to say, it is a set of open source API function libraries about computer vision. This also means,

(1) Whether it is scientific research or commercial application, it can be used for development;

(2) The source code of all API functions is public, and you can see the program steps of its internal implementation;

(3) You can modify the source code of OpenCV and compile and generate the specific API functions you need.

Image processing on ROSMASTER uses certain functions of the OpenCV function library, or it can be said that it is inseparable from most image processing design fields. It has been used in intrusion detection and specific target tracking many years ago. , target detection, face detection, face recognition, face tracking and other fields, OpenCV can be said to show its talents, and these are just the tip of the iceberg of its applications. Now that we realize that OpenCV is so universal, in this chapter we will introduce you to some very basic image processing functions that we use in our courses, as well as some universal functions. Here we first have a general understanding of this knowledge. After a while, there are two practical projects in the back to teach you how to get started, including color recognition and tracking, and face recognition and tracking. However, the powerful application functions provided by OpenCV are far more than this. If you are interested in the development of Opencv computer vision library and want to go deeper. If you know more about it, here are several websites for your reference and study:
