Abstract: A method and apparatus for performing inbuilt calibration of camera system that performs three-dimensional measurements and depth reconstruction are described. In one embodiment, the method includes displaying, using a projector of a capture device, a fiducial projection pattern in response to calibration of the capture device. The method may also include capturing, with a camera of the capture, an image of the fiducial projection pattern. The method may also include determining calibration coefficient values indicative of relative physical relationships of one or more components of the depth camera system based on analysis of the captured image of the fiducial projection pattern.
