Abstract:
1. An aerial photograph image pickup method comprising: making a flying object fly meanderingly, wherein said flying object comprises a GPS device and an image pickup device for taking an image downward, taking the image at each vertex where a direction is changed in the meandering flight, acquiring a three-dimensional coordinate of each vertex by said GPS device, extracting feature points from a common overlap portion of three images taken from at least three vertexes adjacent to each other, performing triplet matching with respect to said three images based on said three-dimensional coordinates and said feature points, performing photogrammetry of measuring points corresponding to said feature points based on said three-dimensional coordinates acquired at two vertexes by said GPS device by determining two images of two vertexes in said images as one set for each set regarding at least two sets and based on said feature points of said two images, and determining said feature points when the surveying results of said measuring points coincide with each other in at least said two sets as tie points for image combination.
