Abstract:
This wind condition determining device is provided with: an image capturing unit which generates a landscape image in which an image of the landscape in the vicinity of the device has been captured; an image extracting unit which, if an image of a linear object suspended between a plurality of structures is present in the landscape image generated by the image capturing unit, extracts the image of the linear object from the landscape image; a difference calculating unit which calculates a difference between a suspension direction in which the linear object is suspended, and a gravitational force direction, on the basis of the image of the linear object extracted by the image extracting unit; and a wind condition determining unit which determines the condition of wind blowing between the structures, on the basis of the difference calculated by the difference calculating unit.
