PROBLEM TO BE SOLVED: To improve measurement accuracy by an aviation photographic measurement method.SOLUTION: An aviation photographic measurement method composed of a plurality of flying bodies 1 loaded with a GPS device and an imaging part is configured to comprise the steps of: setting a plurality of photographing points and setting a photographing area centering around each of the photographing points, respectively; measuring, by the GPS device, a position of the flying body; arriving, by the flying body, at respective corresponding photographing point area and maintaining a position of the photographing point area thereby; acquiring time at which the flying body lastly arrives at the photographing point area; setting shutter timing time after a given time has elapsed since the last arrival time; and photographing an aviation picture at the shutter timing time by the plurality of flying bodies.
Abstract:
PROBLEM TO BE SOLVED: To enable three-dimensional measurement of accurate geography with a simple configuration.SOLUTION: A unified stereo image covering the entire measurement object range and represented by a common three-dimensional coordinates system is created by executing a first process in which a flight vehicle 1 flies in a zigzag pattern in the sky over the measurement object range to respectively acquire static images during going and coming back, a second process for mutually plotting a set of adjacent images to create a stereo image, mutually plotting the other set of adjacent images to create another stereo image, creating two sets of stereo images about three images adjacent in a traveling direction, a third process for connecting the two sets of stereo images by using feature points extracted from a part being an image which is common to between the two sets of stereo images and at which the three images are overlapped, a process for repeating the second process and the third process to connect all of the stereo images in flying and flying back directions by images acquired in the first process, and a process for selecting common tie points from adjacent images in an adjacent course and connecting adjacent stereo images in the course.
