Installing Open CV on Raspberry Pi notes

  • Upgrade Pi to Raspbian to Stretch version
  • Install OpenCV on Raspberry PI 3 with virtual environments per instructions:
  • Couldn't get virtual environments setup, but using pip3 install opencv-contrib-python worked!
  • Got an error when import cv2 said ImportError: libjasper.so.1, libQtGui.so.4, and libQtTest.so.4
    • ran: sudo apt-get install libjasper-dev libqtgui4 libqt4-test
