| Abstract(in English) | The binocular correspondence for an oblique line is ambiguous when its endpoints are occluded. This is a stereoscopic aperture problem caused by uncertainty about the disparity component parallel to the line orientation. We show that the aperture problem in stereo does not occur when unambiguous information about the gaze angle of the fixation point is available, and we present a theory of binocular correspondence that establishes a unique match of lines by utilizing the gaze information from vertical disparities. The theory predicts that when surrounded by a expansion / contraction disparity field, lines in the central region will be displaced on to the plane which is tilted toward an orthogonal direction to the lines orientation. This prediction was tested and confirmed in a psychophysical experiment. The result suggests the existence of a mechanism that interpolates vertical disparities to find the matching solution of lines in an otherwise featureless space. The process of vertical disparity interpolation can be extended to deal with a general correspondence problem in stereo vision. |
