1. An apparatus for estimating a camera pose, the apparatus comprising:
a similar image searcher configured to search for a plurality of images similar to an input image, from among a plurality of previously-stored images, based on the input image;
a clusterer configured to calculate distances between a reference image arbitrarily selected from the plurality of similar images and a plurality of remaining similar images except for the reference image, respectively, based on viewpoint data tagged to each of the plurality of similar images and create a cluster including at least two similar images meeting predetermined conditions, from among the plurality of similar images, based on the calculated distances; and
an estimator configured to estimate a pose of a camera that has generated the input image, based on the cluster.
