Research on Multi-view Stereoscopic Angle Model

Multi-view stereo angle is the key factor for FTV (Free-viewpoint TV) acquisition/stereo display. A multi-view stereo angle model is established. With the model, factors which impact on stereo angle can be found out. Using stereo angle model, multi-view stereo display system can be simulated quantitatively and the relationship between shooting distance and stereo angle is shown. Depending on formula for max fusion limit of human eyes，relationship among max stereo angle, shooting distance and viewing distance can be got. Finally relationship between stereo angle and number of views can be found. The simulation experiments have been verified above results. This results provide a theoretical basis for optimizing multi-view acquisition/stereo display system.
