Claim One:
1. A wide-angle image acquiring method, which photographs an object while using a first camera and a second camera, to acquire a first image and a second image, and which acquires a wide-angle image of the object while using the first image and the second image, comprising: a step of paralleling an Epipolar line of the first image with an Epipolar line of the second image, so that the Epipolar lines are made consistent with each other; a step of correcting distortions of the first image and the second image, each projected on a cylindrical imaging surface; a step of searching for a point which corresponds to an observing point on the first image, on the Epipolar line of the second image; and a step of reconstructing a three-dimensional figure of the object, after acquiring distances in a depth direction from the first and the second cameras to the object, based on a searched result of the step of searching.
