Abstract

The purpose of the present invention is to efficiently retrieve the image data of a specific moving object from the data of images photographed in a plurality of photographing positions. A number of photography and detection apparatuses having an RFID detection function and a photography function are arrayed in the positions where roads cross each other, and detect the RFID of a moving object which passes the photographing positions and transmit the image data of the moving object in association with the detected RFID to the server system. The server system stores the data of images photographed in a plurality of photographing positions in the storage device and retrieves the image data associated with the designated RFID from the storage device.
