Abstract:
A method for providing visual verification of mapped fiducial points on an object with the actual position of the fiducial points in a video image of the object, comprising:monitoring a spatial region including the object by at least two cameras which can map invisible light; monitoring the spatial region by at least one video camera that produces a video image of the spatial region including the object and in which the fiducial points on the object are visible; computing the spatial location of the fiducial points on the object in said monitored spatial region as mapped by said invisible-light cameras; and showing in overlapping relationship on a display the video image in which the fiducial points on the object are visible and also the fiducial points at their computed spatial locations in the same frame of reference as the video image shown on the display, thereby to enable visual verification of the computed spatial locations of the fiducial points with the positions of the fiducial points in the video image shown on the display.
