A surveillance system for detecting and/or characterizing movement of a monitored infrastructure. An improved compromise between tight zone surveillance and number of false alarms is provided by an improved control of a 3D surveillance device. An input functionality is provided for a user to define a 3D subzone within a 3D environment model. A change functionality allows the user to generate a redefined subzone by dragging one of the corner points of the 3D subzone to a different position within a 3D visualization of the 3D environment model, whereby the shape of the 3D subzone is distorted. The input functionality and the change functionality are used to provide to the 3D surveillance device spatial parameters associated with the redefined subzone and the 3D surveillance device is caused to generate an action in case a movement within the redefined subzone is detected by means of the 3D measurement data.

Time-of-flight based 3D surveillance system with flexible surveillance zone definition functionality

A monitoring system for locating and classifying an event in a monitoring area by a computation unit including a visual 3D capturing unit providing geometric 3D information and an acoustic capturing unit providing an acoustic information of the monitoring area. An event detector is configured with an acoustic channel and a visual channel to detect the event. The acoustic channel is configured to detect the event as a sound event in the acoustic information and to determine a localization of the sound. The visual channel is configured to detect the event as a visual event in the geometric 3D information and to derive a localization of the visual event. The event detector provides detected events with a region of interest for detected event, which is analyzed in order to assign the detected event a class within a plurality of event classes.
