Abstract
A method of recognizing consecutive objects on a conveying path in a detection zone arranged on the conveying path comprises the following steps: generating an electromagnetic radio frequency field radiating into the detection zone by way of a radio frequency sensor; measuring a time curve of a dielectric conductivity in the detection zone by using of the radio frequency field of the radio frequency sensor; and determining contour information of the consecutive objects from the time curve of the dielectric conductivity.
