Depth Estimation Using Spherical Mirror Modeling

구면거울 모델링을 이용한 물체의 거리 추정

In this paper, we consider the problem of finding the depth of a object in two images taken with cameras. For solving this problem, we introduce a spherical concave mirror model. First, a virtual concave mirror is assumed, and then a scene is obtained by camera at two different position which are on the surface of the mirror. The depth of object is calculated from two scenes by using the spherical-mirror equation. The algorithm has been tested on a real scene containing several objects, and showed that it is more useful for farther object.
