Abstract

Various aspects of a system and a method for extrinsic camera parameters calibration by use of a three dimensional (3D) calibration are disclosed herein. In accordance with an embodiment, the system includes an electronic device, which receives an image, which includes the 3D calibration object with a plurality of unique identifiers. One or more appearance parameters of the 3D calibration object and/or a plurality of intrinsic camera parameters of an image-capturing device that captured the received image, are further received. A positional probability is computed for each of the plurality of unique identifiers distributed in the received image. The plurality of unique identifiers of the 3D calibration object are located in the received image to calibrate the extrinsic camera parameters based on the computed positional probability, the received one or more appearance parameters of the 3D calibration object, and the plurality of intrinsic camera parameters.
