Abstract
The invention concerns a method for showing three-dimensionally defined fiducial points in a video camera image involving monitoring of a spatial region by at least two cameras which can map invisible light, especially infrared light, and by at least one video camera, computer-assisted analysis of the image data of the cameras, using the three-dimensional data obtained by means of the invisible-light cameras to compute the spatial location of objects located in the monitored spatial region as mapped by the invisible-light cameras, and displaying the fiducial points assigned to the objects together with the video image; the invention also relating to an apparatus for implementing the method or for visually verifying the correct position of an object.
