Quantitative depth based on binocular resolution of visibility constraints is demonstrated in a novel stereogram representing an object, visible to 1 eye only, and seen through an aperture or camouflaged against a background. The monocular region in the display is attached to the binocular region, so that the stereogram represents an object which is only partially visible to the eye that sees it. The results show that this feature is necessary for quantitative depth, which is not found for a fully visible monocular object in the same location, and that depth in these displays, although very precise, is not based on fusional Stereopsis. The findings provide clear support for the existence of a process of da Vinci Stereopsis, but one more sophisticated than the one proposed by K. Nakayama and S. Shimojo (1990).
基于双目可见性约束分辨率的定量深度在一种新颖的立体图中得到了展示，该立体图呈现了一个仅对一只眼睛可见的物体，此物体通过一个孔径可见或与背景形成伪装。显示器中的单目区域与双目区域相连，使得该立体图所呈现的物体对于看到它的眼睛而言只是部分可见。结果表明，这一特征对于定量深度是必要的，在相同位置完全可见的单目物体中并未发现这一特征，并且这些显示器中的深度虽然非常精确，但并非基于融合立体视觉。这些发现为达·芬奇立体视觉过程的存在提供了明确支持，但该过程比K. 中山和S. 下条（1990年）提出的更为复杂。
