Installing OpenCV on an RPi board

Follow these steps to install OpenCV on the RPi:

1. First, we need to install a few dependencies. Run the following command to install all these dependencies:

   sudo apt-get install -y libhdf5-dev libhdf5-serial-dev libatlas-base-dev libjasper-dev libqtgui4 libqt4-test

2. Once the installation is successful, we can install OpenCV on the RPi:

   pip3 install opencv-python==4.0.1.24

3. Once the installation of OpenCV is successful, we can verify it by running the following command:

   python3 -c "import cv2; print(cv2.__version__)"

   The following should be the output:

   4.0.1

This means that the installation is completed and that we can import OpenCV in our Python 3 programs.

Next, we will learn how to overclock the RPi 4B and how to install heatsink on it.
