Abstract:
1. A method for the monitoring of a monitored zone next to and/or in an apparatus having at least one driven, movable part wherein video images are used which were detected in a time sequence by at least two video cameras whose fields of view overlap at least in part in an overlap region in the monitored zone; on the basis of the first video images detected by a first one of the video cameras, a first recognition and/or tracking of virtual objects is carried out and, on the basis of the second video images detected by a second one of the video cameras, a second recognition and/or tracking of virtual objects is carried out, the virtual objects corresponding to real objects at least in the overlap region; for the classification and/or determination of the position and/or the movement of at least one real object in the overlap region, virtual objects corresponding to the real object from the first and second virtual object recognition and/or tracking processes are determined and data determined in each case for both virtual objects on their virtual object recognition and/or tracking are evaluated; and at least one monitoring signal is formed in dependence on the evaluation; and a fusion object is associated with virtual objects of the first and second object recognition and/or tracking processes corresponding to the same object.
