Vision Based Tracker

A vision based tracking system was developed as an alternative input system. It was designed to track colored objects and to estimate their position and orientation. The library is currently used in a mixed reality game project called Airkanoid, an Arkanoid clone.

Technical details

• Speed
  It tracks one bat at 30Hz using a webcam connected to the computer. Two bats take about 50 to 55ms
• Accuracy
  The system works quite well even under different lighting conditions. Specular highlights are causing some troubles. I have a solution in mind that I'm going to test. Stay tuned.
• API
  Small and clean API interface
