Person movement analysis device, person movement analysis system, and person movement analysis method

A person movement analysis system for analyzing a state of movement of persons within a monitored area based on captured images of the monitored area, the system comprising:

• a camera for capturing images of the monitored area;
• and
• a plurality of information processing devices,
• wherein any one of the plurality of information processing devices includes a processor and a memory that stores an instruction, and the processor of the any one of the plurality of information processing devices further comprises, as a configuration when the processor executes the instruction stored in the memory:
• a measurement condition setter that receives an input operation of a user specifying a measurement area in a walkable region, which is a region in the monitored area other than a non-walkable region and specifying at least one of an entry zone and an exit zone of persons relative to the measurement area, and in response to the input operation of the user, sets the measurement area and at least one of the entry zone and the exit zone as a measurement condition;
• a traffic line acquirer that acquires traffic line information of each person detected from the captured images;
• a moving person detector that detects, in the measurement area, persons matching movement patterns defined by at least one of the entry zone and the exit zone, based on the traffic line information acquired by the traffic line acquirer;
• an aggregator that, for a plurality of predetermined aggregation periods, aggregates a result of detection by the moving person detector for each aggregation period and acquires a number of persons that match each movement pattern for each aggregation period;
• and
• an output information generator that generates, based on the result of detection by the moving person detector, output information representing a state of movement of persons for each movement pattern in the measurement area and relating to the number of persons that match each movement pattern for each aggregation period acquired by the aggregator.
