PROBLEM TO BE SOLVED: To provide an automated method and system for updating and correcting an event sequence when subjects randomly merge into a single queue lane.SOLUTION: A method includes: acquiring video data of a queue area from at least one image source S14; searching frames for subjects located near a region of interest of defined start points in the video data S16; tracking a movement of each detected subject through the queue area over a subsequent series of frames S24; determining if a location of the tracked subject reaches a predefined merge point; in response to the tracked subject reaching the predefined merge point, computing an observed sequence of where the tracked subject is located among other subjects approaching an end-event point S26; and updating a sequence of end-events to match the observed sequence of subjects in the single queue lane S28. |
