Abstract
Disclosed herein are an apparatus for estimating a camera pose using multi-view images of a 2D array structure and a method using the same. The method performed by the apparatus includes acquiring multi-view images from a 2D array camera system, forming a 2D image link structure corresponding to the multi-view images in consideration of the geometric structure of the camera system, estimating an initial camera pose based on an adjacent image extracted from the 2D image link structure and a pair of corresponding feature points, and estimating a final camera pose by reconstructing a 3D structure based on the initial camera pose and performing correction so as to minimize a reprojection error of the reconstructed 3D structure.
