摘要

人类甚至可以从2D图像中感知3D形状。斜面可以从倾斜矩形物体的图像中感知到,其中包括纹理梯度和线性透视轮廓。视觉系统如何整合和利用这些图像深度线索?研究了一种新的视觉错觉,为这个问题提供了一些见解。在其上表面绘制磁盘图形的盒状物体以线性透视图像呈现。物体上表面边线的长度被高估了,可能是由于缩短的圆盘作为倾斜的线索。这种错觉效应甚至在观察者估计图像平面上的线长时也会发生,这表明来自磁盘的倾斜感知是强制性的。5个实验结果表明,在倾斜知觉中存在多种深度线索;磁盘的长宽比、纹理梯度、梯形/平行四边形轮廓和盒状对象的侧面。然而,物体外的缩短的圆盘没有被用作深度线索。这些结果表明,属于目标物体的各种深度线索在倾斜感知中是综合的。

The contributions of surface features and contour shapes to object slant perception.

Humans perceive 3D shapes even from 2D images. A slant can be perceived from images of slanted rectangular objects, which include texture gradients and linear perspective contours. How does the visual system integrate and utilize these pictorial depth cues? A new visual illusion that provides some insights into this issue was examined. A box-like object with disk figures drawn on its upper surface was rendered in a linear perspective image. The length of the object's upper surface side line was overestimated, probably due to the foreshortened disks serving as slant cues. This illusory effect occurred even when observers estimated the line length on the image plane, suggesting that the slant perception from the disks was mandatory. Five experiments revealed that multiple depth cues were utilized for the slant perception; the aspect ratio of the disks, texture gradients, trapezium/parallelogram contours, and the side surfaces of the box-like object. However, foreshortened disks outside the object were not utilized as depth cues. These results suggested that various depth cues belonging to the target object are integrated for the slant perception.
