A pre-compiled binary of OpenCV for the Raspberry Pi. It is available in a ".deb" package and will save you countless hours not having to compile it yourself. This may or may not stay updated as I have to manually compile each version. I will try to make available most major versions. This was compiled on a Raspberry Pi 3 Model B+ running raspbian jessie. This version was built with TBB which enables automagic multithreading in many OpenCV algorithms.
- Always good practice to update everything before you install stuff:
sudo apt-get update
sudo apt-get upgrade
sudo rpi-update
- We need to install some packages that allow OpenCV to process images:
sudo apt-get install libtiff5-dev libjasper-dev libpng12-dev
If you get an error about libjpeg-dev try installing this first:
sudo apt-get install libjpeg-dev
- We need to install some packages that allow OpenCV to process videos:
sudo apt-get install libavcodec-dev libavformat-dev libswscale-dev libv4l-dev
- We need to install the GTK library for some GUI stuff like viewing images.
sudo apt-get install libgtk2.0-dev
- We need to install some other packages for various operations in OpenCV:
sudo apt-get install libatlas-base-dev gfortran
- We need to install pip if you haven't done so in the past:
wget https://bootstrap.pypa.io/get-pip.py
sudo python get-pip.py
- Now we can install NumPy - a python library for maths stuff - needed for maths stuff.
sudo pip install numpy
- Download and install the file from this repo called "latest-OpenCV.deb".
wget "https://github.com/jabelone/OpenCV-for-Pi/raw/master/latest-OpenCV.deb"
sudo dpkg -i latest-OpenCV.deb
- Test it installed correctly by doing the following: Open a python shell
python
Run the following commands, it should return the same version you installed.
import cv2
cv2.__version__
- Have fun with OpenCV and open an issue on GitHub if you have any problems or I forget to update it. pyimagesearch is a great resource to get started!
