Computer Vision and Robotics Demo with Raspberry Pi

July 2, 2016

This spring, I spent some time at SAP’s commercial hackerspace. I wanted to explore how computer vision can be used with embedded devices and robotics. I built a demo that can detect QR codes and similar symbols and point a laser at them. Possible applications of this are putting QR codes on objects to help the robot locate them and grab or manipulate objects. Another possible use case is local navigation. A robot could infer its own location and orientation in space by detecting QR codes with known locations.
