発明の名称 (英語) THREE-DIMENSIONAL OBJECT MEASURING DEVICE
発明の概要(英語) A three-dimensional object measuring device comprises a base on which a three-dimensional objectto be imaged is placed, a mirror surface cylinder the inner wall of which surroundsthe base and having a mirror surface, a fish-eye lens which is opposed to the baseand the optical axis of which is aligned with the center axis of the mirror surfacecylinder, and a camera having imaging/recording means for recoding the imageformed by the fish-eye lens. The imaging/recording means of the camera capturesa direct image of when the three-dimensional object placed on the base is viewedand a reflection image of the three-dimensional object on the base reflected atthe mirror surface of the inner wall of the mirror surface cylinder. With this, imagescovering the top and bottom, the left and right, and the whole circumference ofthe three-dimensional object used for stereoscopic measurement can be obtained fromone captured image, correspondence between the feature points of the images canbe easily made, a multipoint-of-view image of the object from all the directions onlyby one imaging can be obtained, and a three-dimensional circumferential shapeof the object can be measured from one image by reflection refraction stereoscopy.
