Installing ROS & OpenCV
Hi! I have successfully installed ROS Kinetic and OpenCV on a Raspberry Pi 3 with an OS of Raspbian Stretch. The whole process took more than a day! I initially installed OpenCV by cloning the official repository from its GitHub page, however I had problems compiling cv_bridge when installing ROS due to version issues. Therefore, I had to install OpenCV version 3 from source, as the previous version 2.4.9.1 was not accepted. As I used a Toshiba Exceria 16GB SD Card, I only had 500MB left after installing OpenCV, therefore I removed the LibreOffice packages, MineCraft Pi and Wolfgram Engine to free up some disk space. Listed below are the two main websites I followed for instructions: Installing ROS Kinetic on the Raspberry Pi Raspbian Stretch: Install OpenCV 3 + Python on your Raspberry Pi Immanuel
