Abstract(in Japanese) (See Japanese page)
Abstract(in English) A vertical component of motion parallax fields, which can be a potential source of information about absolute distance, arises when a field of view is sufficiently large with respect to the extent of a horizontal head movement. The present study investigated the effectiveness of the absolute-distance information in scaling depth from motion parallax. The depth scaling was only effective when a differential perspective invariant was available. This result is similar to that in disparity scaling from binocular stereopsis, and suggests that a common mechanism may be involved in processing the vertical components of the parallax and disparity fields.
