摘要： Methods and systems are disclosed for calibrating a camera using a calibration target apparatus that contains at least one fiducial marking on a planar surface. The set of all planar markings on the apparatus are distinguishable. Parameters of the camera are inferred from at least one image of the calibration target apparatus. In some embodiments, pixel coordinates of identified fiducial markings in an image are used with geometric knowledge of the apparatus to calculate camera parameters.

摘要： An apparatus is disclosed which may serve as a target for calibrating a camera. The apparatus includes a hollow body having an interior surface, an exterior surface and at least one window formed in the hollow body through which the interior surface is visible. A plurality of distinguishable fiducial markers are arranged in a predetermined pattern along the interior and exterior surface of the hollow body. The fiducial markers can be distinguishable such that, for any given image of the target captured by a camera, there is only one position, rotation, distortion value, and focal length for the camera of interest.
