立体视觉深度运动动态随机点立体图 stereo vision depth motion SVC SVC dynamic random dot stereograms

摘要

利用动态随机点立体图，排除心理暗示线索对深度运动的影响，对立体视觉深度运动特性进行了研究。利用主观实验，分析了深度运动物体的运动位置、运动方向和运动速度等运动特性对于立体视觉舒适度(Stereo visual comfort，SVC)的影响, 并提出深度运动情况下的SVC与运动速度的预测模型。实验结果表明，动态随机点立体图中，运动物体的深度运动诱发了透视效果；在交叉视差(屏幕前)和非交叉视差(屏幕后)情况下，立体视觉深度运动导致的SVC不同。对计算得到的SVC的预测值和实测值进行相关性检测，三种深度运动的皮尔森相关系数(Pearson correlation coefficient，PCC)分别为0.956、0.972、0.977，充分表明该预测模型能够准确地预测SVC。

Abstract

Dynamic random-dot stereograms which can eliminate the effects caused by psychological clues of stereo vision were used to study the depth motion characteristics of stereo vision. The effects on Stereo Visual Comfort(SVC) of the depth motion characteristics including motion positions, motion directions and motion velocities were analyzed by subject experiments and a prediction model of visual comfort and motion velocity during depth motion was built. The results show that depth motion induced perspective and depth motion make different visual comforts under crossed disparity(before the screen) or uncrossed disparity(after the screen) in dynamic random dot stereograms. The Pearson Correlation Coefficient(PCC) of three types of depth motion achieves 0.956, 0.972, 0.977, respectively, which indicates that the prediction model can more accurately predict the SVC.
