Abstract
For operators of public or commercial buildings, such as supermarkets, it is interesting to determine how many persons, in particular potential buyers, enter the building each day. In other areas, as well, entering and exiting moving objects are counted: it is typical, for example, that cars driving into and out of a parking garage are counted. The invention relates to a device 1 for counting objects in a monitoring area, having a counting module 9, wherein the counting module comprises an object counter increasing by one counting value when one of the objects completely passes through a counting section 6 in a counting direction 4 as a counting object, having at least one monitoring camera 2 for capturing the monitoring area, wherein the monitoring camera 2 is designed for outputting an image data stream of the monitoring area, and having an extraction module 10 designed for extracting moving image areas in a current image of the image data flow, wherein the moving image areas can represent the objects or partial segments thereof, wherein the counting module 9 is designed for increasing the object counter 9 by a partial value for each current image for one of the moving image area…
