1. An angular direction identifying device comprising a processor that includes:
a photographed image acquiring unit configured to acquire a photographed image by a camera provided in a movable body;
an angular direction information acquiring unit configured to acquire angular direction information in a case where a predetermined physical object suggesting an angular direction is shown in the photographed image, the angular direction information indicating the angular direction suggested by the predetermined physical object;
a view-axis angular direction identifying unit configured to identify an angular direction in which a view axis of the camera is pointed, based on the angular direction information and a position relation between the predetermined physical object in the photographed image and the view axis of the camera; and
a predetermined physical object recognizing unit configured to detect the predetermined physical object from the photographed image based on whether a discrimination sign is put on the predetermined physical object, the discrimination sign indicating that the predetermined physical object is a physical object suggesting the angular direction, wherein
when the predetermined physical object suggesting the angular direction detected by the predetermined physical object recognizing unit is a pole group comprising a plurality of poles arranged in an array direction, the view-axis angular direction identifying unit identifies a direction suggested by the array direction of the pole group, based on the angular direction information, and the view-axis angular direction identifying unit identifies a direction in which the view axis is oriented, based on a position relation between the array direction of the pole group in the photographed image and the view axis of the camera.
