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

摘要

Disclosed is a flow line detection system capable of accurately determining the position of the moving body of each unit of identification information and capable of detecting flow lines even when the position and identification information of the moving bodies frequently cannot be detected. For each unit of identification information of a moving body, a flow line specifying means (83) selects as definite location score relational information only that location score relational information stored in the state storage means which meets a prescribed standard, and the definite location score relational information is reflected in the location score relational information of the time point nearest to the time point corresponding to said definite location score relational information. Said location score relational information is repeatedly set to definite location score relational information, and the flow lines of the moving bodies are specified by the score of the location score relational information at each time point.
