Multiple-Camera Optical Glyph Tracking
The Optical Glyph Tracking technology utilizes image processing and pattern recognition methods to calculate a given object’s position and orientation in the three dimensional space. Cost, precision and reliability are the key aspects when designing such a tracking system. The advantage of optical tracking is that even the simplest cameras can be used to follow the object, and it requires only a single marker. In this paper support for multiple cameras is introduced. All cameras recognize a set of markers on their images and the calculated coordinates are averaged to get a global value. Also multiple different markers are placed on the tracked objects and when even one of them is recognized, the coordinates of the object can be calculated. The Optical Glyph Tracking is implemented as a standalone module and could be used as an input device for any kind of application.
