Abstract

An apparatus comprises a first interface for receiving a plurality of partially overlapping images of an object from a corresponding plurality of cameras being arranged along a first and a second direction according to a camera pattern. The apparatus comprises an analyzing unit configured for selecting at least one corresponding reference point in an overlap area of a set of images, and for determining displacement information along the first and the second direction of the reference point in each of the other images of the set of images. A misalignment of the plurality of images along the first and the second direction is compensated by the displacement information so as to obtain aligned images. The apparatus comprises a determining unit configured for determining offset information between principal points of the plurality of cameras using at least three aligned images. The apparatus comprises a second interface for providing calibration data based on the displacement information and based on the offset information. The calibration data allows for calibrating the plurality of images so as to comply to the camera pattern.
