Embodiment Construction

[0019] A description will be given below of embodiments of the present invention by referring to the accompanying drawings.

[0020] First, in figure 1 In , a description will be given of a flight control system of a flying object to which the present invention is applied.

[0021] exist figure 1 Among them, reference numeral 1 represents a flying object capable of autonomous flight, and reference numeral 2 represents a base control device (base control device) installed on the ground. The base control device 2 is capable of performing data communication with the flying object 1 and controlling the flight of the flying object 1 , setting or changing a flight plan and storing or managing information collected by the flying object 1 .

[0022] The flying object 1 is, for example, a helicopter, which is used as a small flying object for autonomous flight. The helicopter 1 is piloted by remote control from the base control device 2, or the base control device 2 sets a flight pl...

Abstract

The invention relates to an aerial photographing image and an aerial photograph image pickup apparatus. The aerial photograph pickup method comprises a step of making a flying object, which comprises a GPS device (23) and an image pickup device (13) for taking an image downward, fly meanderingly; a step of taking the image at each vertex where a direction is changed in the meandering flight; a step of extracting feature points from a common overlap portion of the images taken from at least three vertexes adjacent to each other; a step of determining two images of two vertexes in the images as one set and acquiring positional information of the two vertexes by the GPS device for each set regarding at least two sets; a step of performing photogrammetry of the measuring points corresponding to the feature points based on the positional information and based on the feature points of the two images; and a step of determining the feature points when the surveying results of the measuring points coincide with each other in at least the two sets as tie points for image combination.

Description

technical field [0001] The present invention relates to an aerial photographic image pickup method and an aerial photographic image pickup device by a small unmanned aerial vehicle (UAV). Background technique [0002] In photography from above or surveying from above, information that cannot be obtained by photography from the ground or surveying on the ground can be obtained, and photography is possible in off-limit areas, Or information can be obtained in areas where surveying is difficult. In addition, in recent years, due to improvements in performance of small flying objects such as small airplanes or small-scale helicopters that are remotely controlled, improvements in remote control technology, and further improvements in performance of image pickup devices, miniaturization With the promotion of and among others, image pickup devices can be installed in small flying objects. By controlling the flying object remotely, photography from above can be performed in an unm...
