Method for adjusting at least one time window and device for tracking moving objects

Abstract

The invention relates to a method (100) for adjusting a time window (32) for tracking an object (14) moving along a transport path (12), comprising the steps of: receiving (102) a plurality of detection signals (26) from a first sensor (16) arranged on the transport path, wherein each detection signal (26) is assigned to an object moving along the transport path; defining (104) a plurality of time windows for a portion of the detection signals (26), wherein the respective assigned object is expected within the respective time window (32) at a second sensor (18) arranged downstream of the first sensor in the transport direction of the object along the transport path;Receiving (106) a plurality of trigger signals (26) from the second sensor in the plurality of time windows, each trigger signal indicating a detection time of the object associated with the corresponding time window at a position of the second sensor on the transport path; determining (108) a deviation between a target detection time (29) and the plurality of detection times; and if the determined deviation exceeds a threshold (110): issuing (116) at least one warning signal and / or adjusting (112) the setting of future time windows (32) based on the determined deviation. Using the method (100), objects can be tracked with minimal effort and therefore at low cost.
