In this tutorial, we will show you how to install OpenCV on Debian 12. For those of you who didn’t know, In the world of digital content and SEO optimization, the role of image processing cannot be underestimated. Images are not just visual elements but also vital for engagement, user experience, and even SEO ranking. To harness the power of image processing, OpenCV stands as an exceptional tool.

This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of OpenCV on a Debian 12 (Bookworm).

Prerequisites

• A server running one of the following operating systems: Debian 12 (Bookworm).
• It’s recommended that you use a fresh OS install to prevent any potential issues.
• SSH access to the server (or just open Terminal if you’re on a desktop).
• An active internet connection. You’ll need an internet connection to download the necessary packages and dependencies for OpenCV.
• A non-root sudo user or access to the root user. We recommend acting as a non-root sudo user, however, as you can harm your system if you’re not careful when acting as the root.

Install OpenCV on Debian 12 Bookworm

Step 1. Before we install any software, it’s important to make sure your system is up to date by running the following apt commands in the terminal:

sudo apt update
sudo apt upgrade

This command will refresh the repository, allowing you to install the latest versions of software packages.

Step 2. Installing OpenCV Dependencies.

OpenCV requires various libraries and development packages. Let’s install them:

sudo apt install build-essential cmake libjpeg-dev libpng-dev libtiff-dev

Step 3. Installing Erlang on Debian 12.

• Method 1: Using apt package manager.

Install the OpenCV package by running the following command:

sudo apt install libopencv-dev python3-opencv

Verify that OpenCV is installed correctly by running the following command:

pkg-config --modversion opencv4

This command should output the version number of OpenCV that you just installed.

• Method 2: Building from source.

Now we clone the OpenCV source code repository by running the following command:

git clone https://github.com/opencv/opencv.git

Create a build directory and navigate to it by running the following commands:

cd opencv
mkdir build
cd build

Configure the build by running the following command:

cmake ..

Build and install OpenCV by running the following commands:

make -j$(nproc)
sudo make install

Verify that OpenCV is installed correctly by running the following command:

pkg-config --modversion opencv4

This command should output the version number of OpenCV that you just installed.
