Evaluation of perceived three-dimensional shape in binocular stereo images

Abstract (in Japanese) (See Japanese page) 
(in English) When we observe a stereoscopic image, the viewer sometimes feels it is a different three-dimensional shape. It seems that the feeling of the stereoscopic image of the observer is related to the reason why the observer feels as a three-dimensional shape different from the actual one. In this experiment, we conducted a simple experiment to measure the depth by instructing gaze points to the left / right / center of a semicircular columnar object and to evaluate the shape perceived by the observer. Experimental results showed that the observer perceived the compression tendency to be more compact than the theoretical value for the left and right sides of the object and perceived the same as the theoretical value about the center. The observer evaluated that the depth of the left and right of the object felt as a slightly compressed shape. About the 2D image, the observer evaluated that a slight depth is felt.
