In this tutorial, I will demonstrate how to track table tennis balls using OpenCV on Raspberry Pi. It can be used to track any circular object as long as it can be detected well from its background. This can be helpful in ball tracking robots and similar projects.
Things you need:
1. Raspberry Pi (with latest Raspbian installed, you can get it from here: https://www.raspberrypi.org/downloads/ Follow installation instructions on the same site)
2. USB Webcam (test one that Rasppi supports)
3. A linux host (preferably Linux Mint/Ububtu ) I have tested with Linux Mint 17.
4. Experience with debian systems
