A rectangularity postulate has been used in algorithms for the purpose of interpreting two-dimensional representations of rectilinear objects. This rectangularity postulate may affect the perception of true surfaces. In this study, rectangular surfaces and trapezoidal surfaces--the latter simulating the horizontal slant-in-depth of the rectangular surfaces--were viewed under static-monocular, moving-monocular, and static-binocular conditions, both with and without a background pattern. The static-binocular condition elicited the greatest number of accurate responses. The moving-monocular condition did not elicit significantly more accurate responses than the static-monocular viewing condition did. The effect of background pattern was insignificant. These results were unexpected in terms of ecological validity and (regarding moving-monocular viewing) because of the importance of the role of relative visual motion in the detection of object motion. However, the results are consistent with the perception of depth separation of two discrete objects.
为了解释直线物体的二维表示，算法中使用了矩形假设。这种矩形假设可能会影响对真实表面的感知。在本研究中，矩形表面和梯形表面（后者模拟矩形表面的水平深度倾斜）在静态单眼、动态单眼和静态双眼条件下进行观察，观察时均有或没有背景图案。静态双眼条件引发的准确反应数量最多。动态单眼条件引发的准确反应数量并不比静态单眼观察条件下显著更多。背景图案的影响不显著。就生态有效性而言，这些结果出乎意料，并且（关于动态单眼观察）由于相对视觉运动在物体运动检测中的重要作用。然而，这些结果与两个离散物体的深度分离感知是一致的。
