Abstract
Techniques of calibrating telepresence videoconferencing displays and cameras include providing 6 DoF camera locations and orientation vectors in display reference frame based on a plurality of images that indicate specified mirror-plane points of a mirror and specified reflected display plane points. In some implementations, the specified mirror-plane points are located at fiducial markers printed on the mirror. In some implementations, the specified reflected display plane points are located in a checkerboard pattern of fiducial markers on the display.
