基于多视点立体角度模型的相关研究

Research on Multi-view Stereoscopic Angle Model

多视点立体视角是FTV(Free-viewpoint TV)多视点采集/立体显示的关键因素,该文建立了多视点立体视角的数学模型。根据此模型获得了制约立体角度的相关因素,并定量模拟出用水平摄像机阵列拍摄物体时,拍摄距离与立体视角的关系;进一步根据人眼最大融合极限求出可防止产生重影、双轮廓的最大立体角与拍摄距离和观看距离之间的关系。最后导出立体角度与视点数之间的制约关系。仿真实验验证了所得结果的正确性。该文结果可为优化自由视点多视采集/立体显示系统提供理论依据。

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.
