In the method of obtaining captures images, there is overlaps in images in the flight direction and in a direction (cross direction) that crosses the flight direction. A predetermined number of the captured images containing overlapping sections that include a target point are selected out of the obtained images in the flight direction and/or the cross direction. From the overlap sections of these captured images, selected images are obtained by selecting image sections within a specific range that contains the target point. Using the flight direction and the cross direction as axes for a matrix, the selected images are arranged to create an aerial photograph data set.

Method of producing and displaying an aerial photograph data set

A method of producing aerial photograph data is provided which is capable of positively utilizing stored photograph data and an image of a desired object included in a photographed image. The method includes a step of determining a distance between a position of a virtual photographic principal point (virtual photographic principal point position) obtained by the use of spatial position information of a target point and spatial direction of a view vector and a position of an actual photographic principal point (actual photographic principal point position) of each of a plurality of aerial photographs to automatically select a specific aerial photograph, and a step of extracting, from the specific aerial photograph, a selected image having the target point arranged at a predetermined position therein.
