FLOW LINE DETECTION SYSTEM, FLOW LINE DETECTION METHOD, AND FLOW LINE DETECTION PROGRAM

摘要

A flow line detection system capable of accurately determining a position of a mobile object of each piece of identification information and detecting a flow line even when there are frequent cases where a position or identification information of a mobile object cannot be detected is provided. Flow line specification means 83: selects, for each piece of mobile object identification information, position-score correspondence information that satisfies a predetermined criterion from among position-score correspondence information stored in state storage means, as definite position-score correspondence information; repeatedly performs a process of reflecting the definite position-score correspondence information in position-score correspondence information of a time nearest a time corresponding to the definite position-score correspondence information and setting the position-score correspondence information of the nearest time as definite position-score correspondence information; and specifies a flow line of a mobile object from a score in position-score correspondence information of each time.
