Abstract
A method of calibrating a six-degree-of-freedom (6DoF) pose of a natural user interface (NUI) camera relative to a display is provided. Calibration video imaging an environment from a calibration perspective, which sites the display and one or more features, is received from the NUI camera or a calibration camera. A three-dimensional map of the environment, which defines a 6DoF pose of the display and a three-dimensional location of each of the one or more features, is modeled from the calibration video. Primary video imaging the environment from an operation perspective, which sites the one or more features, is received from the NUI camera. A 6DoF pose of the NUI camera is found within the three-dimensional map of the environment based on the operation perspective view of the one or more features.
