Abstract:
1. A flow line detection system comprising: a position-score correspondence information creation unit implemented at least by hardware including a processor and that is for creating position-score correspondence information for each piece of mobile object identification information, the position-score correspondence information being information in which a score indicating a level of possibility that a mobile object having a unique piece of identification information exists is set for each position in a tracking area of the mobile object; a state storage unit for storing position-score correspondence information of each detection time of a position coordinate of the mobile object and the mobile object identification information; and a flow line specification unit implemented at least by hardware including a processor and that is for: selecting, for each piece of mobile object identification information, position-score correspondence information that satisfies a criterion from among the position-score correspondence information stored in the state storage unit, as definite position-score correspondence information; repeatedly performing a process of reflecting the definite position-score correspondence information in position-score correspondence information of a detection time nearest a detection time corresponding to the definite position-score correspondence information and setting the position-score correspondence information of the nearest detection time as definite position-score correspondence information; and specifying a flow line of the mobile object from the score in position-score correspondence information of each detection time.
