If you use ROS when creating robots, then you probably know that it supports utilization of stereo cameras. For example, you can create a depth map of the visible field of view, or make a point cloud. I began to wonder how easy it would be to use our StereoPi, a stereo camera with Raspberry Pi inside, in ROS. Earlier, I’d tested and confirmed that a depth map is easily built using OpenCV; but I had never tried ROS - and so, I decided to conduct this new experiment, and document my process of looking for the solution.
1. Does ROS for Raspberry Pi exist?
