Patent ID: 8564659

Claim:
A flow line recognition system comprising: a plurality of first devices each of which is located in one of a plurality of positions in a monitoring area to detect a position of a moving object in the monitoring area; a first recording unit which records first moving object information including first position information indicative of the position of the moving object detected by the first devices and first time information indicative of a time when the moving object is in the detected position; a second device which is located around a specific area to detect a position of the moving object in the specific area, which is a part of the monitoring area, more accurately than the first devices; a second recording unit which records second moving object information including second position information indicative of the position of the moving object detected by the second device and second time information indicative of a time when the moving object is in the detected position; a comparison unit which compares the first moving object information to the second moving object information; and a coupling unit which couples the first moving object information and the second moving object information as coupled information for a particular moving object if, based on the comparison, a difference between the first position information and the second position information is not greater than a first predetermined value and if, based on the comparison, a difference between the first time information and the second time information is not greater than a second predetermined value.
