Document Type and Number:
WIPO Patent Application WO/2019/239958
Kind Code:
A1
Abstract:
With respect to aerial photogrammetry using an unmanned aerial vehicle, the present invention prevents a defective ground surface image caused by an undulation in a ground surface, while also suppressing an increase in the number of captured images. Provided is an unmanned aerial vehicle for use in aerial photogrammetry comprising an image capturing means which captures images of a ground surface, wherein said unmanned aerial vehicle is characterized by having a distance measuring means which can measure a distance between the unmanned aerial vehicle and the ground surface, and an overlap controlling means which controls overlap, said overlap being the degree to which the images, which are adjacent in the traveling direction of the unmanned aerial vehicle, are overlapped, and further characterized by the overlap controlling means automatically adjusting, in accordance with a change in a measurement from the distance measuring means, an image capturing baseline length, which is the distance from one image capturing point to the next image capturing point, such that the overlap does not fall below a prescribed threshold.
