Abstract
A three-dimensional coordinate position of a calibration device is determined. Further, a code is emitted to an image capture device. The code indicates the three-dimensional coordinate position of the calibration device. In addition, an image of light emitted from the calibration device is captured. The light includes the code. An image capture device three-dimensional coordinate position of the calibration device is calibrated according to the real world three-dimensional coordinate position of the calibration device indicated by the code.
