摘要： 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 a reference point in an overlap area of one of the images, and for determining displacement information along the first and the second direction of the reference point in each of the other 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

摘要： The invention provides a light-field camera for capturing multiple views of a scene, the multiple views representing samples of a light-field, the light-field camera comprises:
a primary camera configured for capturing a primary digital two-dimensional image of the scene;
a two-dimensional camera array comprising a plurality of secondary cameras, wherein each of the secondary cameras is configured for capturing a secondary digital two-dimensional image of the scene in order to produce at least one set of secondary digital two-dimensional images of the scene;
a semitransparent mirror arranged in such way that an incident light beam originating from the scene is split up in a first partial light beam, which is directed to the primary camera, and a second partial light beam, which is directed to the camera array; and
a processing unit configured for receiving the primary digital two-dimensional image and the at least one set of secondary digital two-dimensional images and configured for computing depth information for the primary digital two-dimensional image or a digital two-dimensional image corresponding to the primary digital two-dimensional image based on the set of secondary digital two-dimensional images.
