Abstract:
1. A device for recognizing and classifying objects in object and human traffic within a detection area, comprising: magnetic field generators configured to generate fields which are changed by at least one corresponding object in the detection area to create associated field changes; first sensors configured to repeatedly record the field changes and provide corresponding magnetic field signals, the first sensors being provided with a compensation unit configured to eliminate an influence of a primary field of the magnetic field generators on the first sensors so that said first sensors only record stray fields caused by the at least one corresponding object; second sensors configured to record a defined surrounding of the at least one corresponding object in real-time with relation to the first sensors and provide corresponding second sensor signals; and an analytical unit configured to correlate and collate the signals of at least said first and second sensors with each other to provide a corresponding shape, spatial position and/or spatial orientation of the at least one corresponding object.
