Abstract :
A model for a model-based 3D-position determination system for a passive object is presented. Infrared emitter/receiver pairs are proposed as sensing parts to acquire information on a ball shaped object´s position. A 3D reflection map model is derived through geometrical considerations. The model is found to be in good accordance with real measurements obtained in the laboratory.
