Can I build OpenCV on my Desktop Computer from source, then transfer the build folder to a raspberry pi for use on a raspberry pi?

Hello, I have built OpenCV 3.1.0 on my Windows computer. I used python 2.7, have numpy installed, and have added a few modules from opencv_contrib. The build works on my computer in the python terminal I can import cv2 and have made a test program and that also works. I was wondering if I can zip up my build folder and transfer it to my Raspberry Pi 3, then unzip and start using OpenCV on my Raspberry Pi, or do I have to rebuild OpenCV from scratch again on my Raspberry Pi 3.

Thank you,

  • no, you can't simply zip your desktop environment, and put it on a raspi, the underlying hardware architecture differs.
  • you can build it from scratch on the actual device, but this will take ages. (and you'd need a quite large disc, ~2gb temp files produced during build)
  • you can try to cross-compile it on your desktop box, and later transfer it to your raspi
  • there are prebuilt cv2 packages for raspian, unfortunately they're stone-age, something like 2.4.8

The answer is NO! U will get an errors during make -j(x). For raspberry pi 3. u will have to start over from beginning install libraries to make install. Recently, I had problem w/out install libraries for 5 times. but i'm getting a lot of an errors during make -j4.
