Although it will take a little longer, I think it is convenient. This way it will be highly optimized for your system and you will always get the latest stable version. There is another way and that is to install it from the source code. Method 2: Install OpenCV from the source code You will get a screen output similar to this: 4.2.0 So, you need to open a terminal either from the main menu or from a shortcut like a dock or a shortcut and execute these commands sudo apt updateĪnd if you want to verify the installation, you can execute python3 -c 'import cv2 print(cv2._version_)' And yes, OpenCV is available in these repositories. The first installation method is the easiest you can imagine because it is by using the Ubuntu repositories. Method 1: Install OpenCV on Ubuntu 20.04 via APT Note in this post, we will install OpenCV prepared for Python. In any case, both installation methods work fine on Ubuntu 20.04. Like almost everything in Linux, we have several ways to install OpenCV and it depends on your computer and your needs to install it. Some of the things you can do with OpenCV by integrating it into your favorite programming language are identifying objects, faces, classifying human actions in video, tracking object movements, extracting 3D models, finding similar images, and so on. So we can use it in almost any application we create. Another great advantage of OpenCV is that this great library has interfaces for multiple languages, including Python, Java, and C++.
