Abstract: Monitoring systems typically comprise a plurality of monitoring cameras, which are disposed in different locations for monitoring one or more monitoring regions. Monitoring systems of said type are used, for example, to monitor places, inter-sections, buildings, libraries, train stations, factories, prisons, retirement homes and the like. The invention relates to a monitoring system (1) for monitoring a plurality of monitoring regions (5), wherein the monitoring system (1) can be and/or is controlled by at least one human observer (4), comprising a status detection module (8), which is designed and/or arranged to determine the monitoring status of the observer (4) based on optically detected status signals of the observer (4).

Abstract: A device for segmenting an object in an image, in which a surveillance region containing one or more objects is depicted or depictable in image, has an estimating module which is designed to estimate a distance in the surveillance region based on a possible object pixel of object in image, a segmenting module which is designed to segment object containing object pixel according to a segmentation strategy, and a strategy module which is programmed and/or electronically configured to adapt the segmentation strategy to object depending on the estimated distance.

Abstract: The invention relates to video surveillance systems that are used, for example, for surveying public places, stations, streets, industrial estates, buildings or similar. Said video surveillance systems comprise one or more surveillance cameras that are oriented towards surveillance scenes and transfer image data streams, in the form of image sequences, to an evaluation centre. The invention also relates to a device (1) for identifying and/or classifying a movement pattern in an image sequence of a surveillance scene comprising a plurality of moving objects, an interface (2) for recording the image sequence, a calculation module (5) for determining an optical flow field (10) in the surveillance scene by evaluating the image sequence and an identification module (6) that is designed in terms of programming and/or circuitry such that the optical field and/or partial areas thereof are compared to one or more patterns in order to identify the movement pattern in the image sequence.

Abstract: A method for detection and/or tracking of objects in motion 16 in a scene under surveillance 15, in which besides the objects in motion 16, interfering objects and/or interfering regions—both hereinafter called interfering factors 17, 23—can occur, is proposed, in which the scene under surveillance 15, a plurality of regions are defined that are divided up into various region classes; and a first region class D1, 5 includes sensitive regions, in which no and/or only insignificant interfering factors 17, 23 are located and/or are to be expected; and for detection and/or tracking of the objects in motion 16 in the sensitive regions, a sensitive content analysis is performed, and a second region class D2, 6 includes semi-sensitive regions 19, in which interfering factors 17, 23 are located and/or are to be expected, and for detection and/or tracking of the objects in motion 16 in the semi-sensitive regions 19, a semi-sensitive content analysis is performed, which is limited and/or modified compared to the sensit

Abstract: Video monitoring systems are commonly used for monitoring streets, junctions, squares, and also public buildings, museums, prisons. Video monitoring systems which output the results for the viewing areas/objects in the scene in metric units, such as lengths in meters and speed in meters per second, or the absolute and/or relative positioning in a camera network, require knowledge of camera parameters such as e.g. the position, orientation, and aperture angle of the camera(s). These parameters are usually manually measured at high cost during the installation process, for example special patterns (sample patterns) are used, or people walking backwards and forwards in front of the camera. A monitoring camera 1 is proposed, according to which the monitoring camera 1 is positioned and/or can be positioned for monitoring at a stationary monitoring position, with a calibration aid system 5, wherein the calibration aid system 5 is designed for determining the stationary monitoring position of the monitoring camera.

Abstract: In automatic assessment or surveillance with camera-based surveillance systems, it is of particular interest to detect moving surveillance objects, such as persons or motor vehicles, and track them over time so that if there are unusual trajectories or unusual behavior, an alarm can be tripped.

Abstract: Video surveillance systems are used for monitoring such areas as streets, railroad stations, industrial plants, buildings, or squares with video cameras, and on the basis of the sequences of images recorded with the video cameras, discovering anomalies in the monitored areas. A method for detecting image regions that are conspicuous in terms of the movement in them in a sequence of images of a scene and a corresponding apparatus and computer program are proposed, in which a current optical flow field in the sequence of images is calculated that includes motion vectors of image regions of the scene; an optical main flow field is determined that includes main flow directions of image regions of the scene; and a counterflow field with motion vectors of image regions that are conspicuous in terms of the movement in them is formed from image regions of the scene whose motion vectors are oriented differently from the main flow directions.

Abstract: In a method and an apparatus for generating a depth map of a scene to be recorded with a video camera, the scene is recorded at a plurality of focus settings differing from one another, and the focus setting proceeds through the depth range of the scene in increments; the image components recorded in focus at a given focus setting are assigned the depth corresponding to that focus setting, creating a first depth map; the scene is recorded a plurality of times, each at a different zoom setting, and from the geometric changes in image components, the depth of the respective image component is calculated, creating a second depth map; and from the two depth maps, a combined depth map is formed.
