Abstract:
1. A monitoring system comprising a plurality of monitoring terminals communicably connected to each other, each monitoring terminal comprising: an imaging portion for imaging a monitoring area allocated to an own-terminal; a tracing portion for processing an imaged image of the imaging portion and tracing a target person traveling in the monitoring area; a tracing information creation portion for creating tracing information associating the target person traced by the tracing portion with tracing start time, tracing stop time, and characteristic information of the target person; a tracing information storage portion for storing the tracing information created by the tracing information creation portion; a tracing information notification portion for notifying the tracing information created by the tracing information creation portion to the other monitoring terminals; and a travel time distribution data generation portion for using the tracing information stored in the tracing information storage portion and the tracing information notified from the other monitoring terminals to generate travel time distribution data that aggregates distributions of the target person's travel time from the own-terminal monitoring area to the monitoring area of each monitoring terminal, the travel time distribution data generation portion using, for each tracing information notified from each monitoring terminal, the characteristic information of the target person included in the notified tracing information to search whether the tracing information storage portion stores the tracing information of a person who is relevant to the target person, the travel time distribution data generation portion calculating, if the tracing information of the relevant target person is searched out, a first travel time as a time difference between the tracing stop time of the current searched-out tracing information and the tracing start time of the notified tracing information, and a second travel time as a time difference between the tracing start time of the current searched-out tracing information and the tracing stop time of the notified tracing information, and the travel time distribution data generation portion generating travel time distribution data that aggregates distributions of the time width from the first travel time to the second travel time thus calculated.
