1. An apparatus for image matching between multiview cameras, the apparatus comprising: a matching processing unit to match a corner associated with a pattern model with a corner point included in a point cloud obtained from a depth camera, to obtain a first parameter, and to match the point cloud with the pattern model by determining a position at which a difference between an intensity corresponding to a depth value of the corner point included in the point cloud and a gradient of the pattern model is minimized, to obtain a second parameter; and a parameter obtaining unit to obtain the first parameter and the second parameter for the depth camera, based on a result of the matching, and wherein the pattern model displayed on a chess board includes an object represented by the gradient and the corner of the chess board.
