| 中文摘要: |
| NAKAYAMA和SHIMOJO提出了一种新形式的基于遮挡几何学恢复深度的da Vinci立体视. 尽管对该研究中采用的立体图中的单眼性条棒的深度来源提出质疑，COOK和GILLAM通过构建一种新颖的侵入构型，发现所有观察者都不能观察到双眼性融合所预期的3-D弯曲表面，从而肯定了某种da Vinci立体视的存在.通过将原始侵入构型在垂直方向上进行拉伸，以减小构型的视差梯度，发现所有观察者都能够观察到容易识别的3-D表面，从而证明侵入构型的深度还是基于融合性立体视. |
| 英文摘要: |
| NAKAYAMA and SHIMOJO proposed a new form of da Vinci stereopsis based on occlusion geometry to recover depth. Although they questioned the source of the depth of the monocular bars in the stereograms adopted by NAKAYAMA and SHIMOJO, COOK and GILLAM constructed a novel intrusion configuration and found that none of their observers could observe the 3-D curved surfaces expected by binocular fusion, therefore confirmed the existence of some form of da Vinci stereopsis. By stretching the original intrusion configurations in the vertical direction to reduce the disparity gradients of the configurations , it is found that all observers could observe easily identified complex 3-D surfaces, thus proving that the depths in the intrusion configurations are still based on fusional stereopsis. |
