OpenCV Installation
Installing OpenCV on the WalnutPi 2B is very simple, just use pip to install it. It is recommended to install the opencv-contrib-python library, which includes the OpenCV main module and contrib module, providing complete functionality.
Basic Image Operations
In the previous section, after successfully installing OpenCV on the WalnutPi, this section will learn to implement some basic image operations using Python programming with the OpenCV library, such as: opening (reading) images, displaying images, saving images, and getting image property information.

Using USB Camera
The camera is like OpenCV's eyes. With a camera, you can process video streams and images captured by the camera in real-time, implementing image processing and machine vision algorithms on them.
