Claim 0:
1. A surveillance system (1),
comprising an interface to a camera network (3) for video surveillance of a surveillance area (2), wherein the camera network (3) comprises a plurality of cameras (3a, b), each for capturing a surveillance subarea (2a, b) of the surveillance area (2), wherein the plurality of cameras (3a, b) are designed to provide surveillance images (6a, b) of the surveillance subareas (2a, b),
comprising a surveillance device (5) for re-identifying people (4) in the surveillance images (6a, b), wherein the surveillance device (5) comprises a person detection module (9), which person detection module (9) is designed to detect people (4) in the surveillance images (6a, b), wherein the surveillance device (5) comprises an object detection module (10), which object detection module (10) is designed to detect objects (8) in the surveillance images (6a, b), which detection involves obtaining object information for the detected objects (8), wherein the surveillance device (5) comprises an assignment module (12), which assignment module (12) is designed to assign at least one item of object information to a person (4),
wherein
the surveillance device (5) comprises an action detection module (11), wherein the action detection module (11) is designed to detect an action of the person (4) on an object of the detected objects (8), wherein the assignment module (12) is designed to, when at least one action condition is satisfied, assign object information for the object (8) to the person (4) for re-identification,
wherein the surveillance device (5) comprises a comparison module (13), wherein the comparison module (13) is designed to compare the assigned object information from a plurality of different surveillance subareas (2a, b), wherein the person (4) is re-identified in the surveillance images (6a, b) when there is a match for the assigned object information from at least two surveillance subareas (2a, b).
