Surveillance Camera, Method For Calibrating the Surveillance Camera, and Use of the Surveillance Camera

摘要

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.
