I have been trying to install OpenCV on my Raspberry Pi with Python 3. I have followed this tutorial http://mitchtech.net/raspberry-pi-opencv/ and when I get to the make command it gets to around 14 percent and stops because of an error. Can anyone help me install OpenCV?
Installing OpenCV is pretty much straightforward process, it just take a lot of time. mitchtech is a good source but it is for old Raspbian not for the new ones. I googled a lot for the last few months to make a cheat sheet, and I made one. You can download my cheat sheet and try it out. I recommend you install OpenCV for Python 2 not 3, and I also recommend that you stick to the cheat sheet especially in step 12. Sometime when you use all the cores the process fails to continue. I also recommend you use a 2A, 5V Adapter. If it works for you please accept my answer.
Best way to install OpenCV on on Raspberry pi is to use:
sudo apt install python3-opencv
instead of pip. As suggested by https://stackoverflow.com/a/60237868/9697329
