摘要： 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.

摘要： A capture device for imaging a person, in particular the face or a part of the face of the person, the capture device comprises at least one camera for capturing an image of the person. The capture device comprises an infinity mirror comprising at least two mirror surfaces arranged oppositely from each other, a light source for emitting light, and a front side to look inside the infinity mirror. The infinity mirror is arranged at the capture device and placed and oriented relative to the capture device so that a capture range with an insight axis and an insight distance for the person is defined and defined capturing of the person by means of the at least one camera is provided when the person is positioned according to the capture range.
