Installing OpenCV on a Raspberry Pi is a relatively easy method. In this guide, we’ll show you how to install OpenCV 4 on your Raspberry Pi 4.

A great way to get started with computer vision is to use the OpenCV library on a Raspberry Pi. OpenCV is a powerful library that can be used to develop computer vision applications

Required Material

In this tutorial, you will learn how to install OpenCV on your Raspberry Pi. You will need the following items to complete this tutorial: –

Raspberry Pi
MicroSD card
USB power supply

Mouse First

First, make sure you have a good power supply and a reliable SD card. We recommend using a 16GB SD card or larger.

Check the Raspberry Pi OS version on Raspberry PI

cat /etc/os-release

1	cat /etc/os-release

Here is what mine:

Set Up Your Raspberry Pi

First, we need to make sure that our Raspberry Pi is up to date. We can do this by running the following commands: Cool, we’re ready. Let’s update the Pi:

sudo apt-get update &amp;&amp; sudo apt-get upgrade

1	sudo apt-get update && sudo apt-get upgrade

Now that our Raspberry Pi is up to date.

Install Python

Once we have updated Raspberry Pi OS, we go to the terminal and type python3

and as you will notice, python is already installed, this time in version 3.9.2.

If you don’t have Python then use the following command will download Python directly onto your machine.

<span class="enlighter-text">sudo apt-get install python3</span>

1	<span class="enlighter-text">sudo apt-get install python3</span>

Install pip

Python package manager (Pip) is a package manager for Python that allows you to install and manage software packages written in Python.

sudo apt-get install python3-pip

1	sudo apt-get install python3-pip

This will install the latest version of pip. Once pip is installed, you can use it to install packages from the Python Package Index, a repository of software written in Python.
