Verfahren zur Kontrolle von Zugangsberechtigungen durch ein Zugangskontrollsystem

A method for monitoring access authorizations by an access monitoring system is proposed in the course of which by means of a first method, the data carriers or the mobile electronic devices, on which a valid access authorization or an ID to which a valid access authorization is unambiguously assigned, are detected and the current position of the data carriers or mobile electronic devices is determined by means of at least three reading devices by trilateration or multilateration, wherein by means of a second imaging method which is executed parallel to the first method, the current position of all persons presented in the entry area of the access monitoring system is detected by means of cameras, whereby the persons having a valid access authorization and all persons present in the entry area are detected spatially in real time, so that an ID map and a people map is created, wherein the ID map corresponds to the spatial distribution of the persons who have a valid access authorization and the people map corresponds to the spatial distribution of all the persons in the entry area of the access monitoring system, wherein in the course of a matching of the ID map with the people map an overlay map is created in which the persons who have a valid access authorization stored on a data carrier or a mobile electronic device or an ID to which at least one valid access authorization is unambiguously assigned and the persons without a valid access authorization are identified.
