Abstract
Various aspects of a system and a method for camera calibration by use of a rotatable three-dimensional (3-D) calibration object are disclosed herein. In accordance with an embodiment, the system includes a first electronic device, which determines a rotation pattern of the 3-D calibration object, based on a set of pre-selected images. The set of pre-selected images includes the 3-D calibration object captured at pre-defined viewing angles. Control information is communicated by the first electronic device to a second electronic device associated with the 3-D calibration object to rotate the 3-D calibration object in accordance with the determined rotation pattern. A plurality of image frames of the 3-D calibration object are captured to calibrate intrinsic and/or extrinsic camera parameters of the first electronic device.
