Abstract
An apparatus for measuring three-dimension information of an object has an image reader, a corresponding point detector and a three-dimension information calculator. The image reader reads a pair of images recorded in a recording medium in the apparatus. Note that, the object is cylindrical and a pair of occluding contours is reflected in each of the pair of images. The corresponding point detector detects at least one pair of corresponding points, which is an imaginary pair of images of at least one measuring point positioned on a central axis, on a pair of bisecting lines. The three-dimension information calculator calculates the three-dimension position of the at least one measuring point on the basis of the at least one pair of corresponding points by applying a triangulation method.
