This research was designed to examine how human observers are able to perceive the 3-dimensional structure of smoothly curved surfaces from projected patterns of surface contours. Displays were generated by using a method of double projection that made it possible to cover a surface with a wide range of contour patterns of varying geometric structure and to eliminate systematic variations of image shading. The compelling impression of 3-dimensional form from these patterns provides strong evidence that the ability of observers to perceptually interpret surface contours is considerably less restrictive than would be reasonable to expect on the basis of existing computational models. Results suggest that the perceptual analysis of surface contours is able to exploit statistical regularities of contour structure over appropriately large regions of visual space.
本研究旨在探讨人类观察者如何从曲面轮廓的投影图案中感知平滑曲面的三维结构。通过使用双重投影方法生成显示，这种方法能够用各种几何结构不同的轮廓图案覆盖一个表面，并消除图像阴影的系统变化。这些图案所产生的令人信服的三维形状印象提供了强有力的证据，表明观察者在感知上解释表面轮廓的能力比基于现有计算模型所预期的要宽松得多。结果表明，表面轮廓的感知分析能够利用视觉空间中适当大区域内轮廓结构的统计规律。
