1. A position and azimuth detecting deviceincluding:

  • a photographing instructing unit that acquires an output signal of a sensor mounted on equipment and instructs a photographing apparatus mounted on the equipment to perform photographing based on the output signal;

    a mark reading unit that reads from a mark included in an image photographed based on the instruction from the photographing instructing unit, position information and azimuth information included in the mark;

    a relative position and azimuth calculating unit that calculates a relative position and a relative azimuth of the equipment to the mark based on a geometric shape of the mark included in the image; and

    a position and azimuth calculating unit that calculates an absolute position and an absolute azimuth of the equipment based on the position information, the azimuth information, the relative position and the relative azimuth,wherein the photographing instructing unitinstructs the photographing apparatus to perform photographing when the output signal of the sensor has a shape associated with a position of the mark, wherein the output signal of the sensor is a signal associated with the position of the mark based on motion information of a user of the equipment.
