<p>[Problem] To accurately and rapidly estimate insolation while taking into account the effect of an obstacle obstructing sunlight. [Solution] The insolation estimation device of the present invention is provided with: an estimation information acquiring unit for acquiring estimation information including a time at which insolation is estimated, a location, and a line-of-sight direction based on the location; a 3D model acquiring unit for acquiring a 3D model of a periphery of the acquired location, the 3D model including a peripheral feature; a solar azimuth calculation unit for calculating the azimuth of the sun at the time and location on the basis of the estimation information; a sky map imaging unit for capturing an image of the entire sky in the line-of-sight direction included in the estimation information and generating a two-dimensional sky map; a sector division unit for dividing the entire sky into a plurality of divisions, generating a plurality of sky sectors, and associating the sky sectors with pixels of the two-dimensional sky map; a sector insolation calculation unit for calculating insolation from the sun positioned at the azimuth calculated by the solar azimuth calculation unit for each of the pixels associated with the sky sectors and adjusting the insolation according to whether a peripheral feature that obstructs sunlight is present, and a total insolation calculation unit for integrating, for all the sky sectors, the insolations of the pixels associated with the sky sectors as calculated by the sector insolation calculation unit and calculating a total insolation.</p> |
