A shooting method of stitched aerial oblique photography

Abstract

The invention provides a photographing method for splicing aviation oblique photography. The photographing method comprises the following steps: S1, moving an aircraft to a preset photographing position, rotating a first cabin, and completing photographing of two oblique cameras in the first cabin in multiple angles; S2, rotating a second cabin, and completing photographing of two oblique camerasin the second cabin in multiple angles; S3, completing photographing in reset preset positions, overlapping splicing images taken in adjacent preset positions, and mutually overlapping images taken bythe two oblique cameras in the first cabin and the two oblique cameras in the second cabin in adjacent angles in a same preset photographing position. The whole photographing method provided by the invention is simple and reliable in process, high in photographing precision, low in requirement on oblique cameras and capable of achieving multi-angle free photographing; expanded spliced images acquired by using the photographing method can be conveniently processed later, and later modeling efficiency and model precision can be improved.

Description

technical field [0001] The invention relates to a shooting method of spliced ​​aerial oblique photography. Background technique [0002] The aerial panoramic oblique photography device belongs to the technical category of aerial photogrammetry and aerial oblique photography. Aerial photogrammetry is based on aerial photographing images and using photogrammetry technology to produce various surveying and mapping products, including digital ground models, orthophoto maps and line-drawn maps. Aerial oblique photogrammetry is to obtain the side texture of ground objects by shooting oblique images, and then establish a real 3D model of the city through photogrammetry technology. [0003] Aerial oblique photography is a breakthrough of traditional aerial photogrammetry. Through the combination of cameras with different perspectives, it can shoot natural objects and artificial buildings on the ground. Existing aerial oblique photography devices generally adopt the form of a five-...

AI Technical Summary

Problems solved by technology

[0007] The defect of the prior art is that currently used aerial oblique photography devices generally use multiple built-in cameras, which can be placed at different angles to achieve multiple angles of shooting to obtain panoramic images of the ground

The number of built-in cameras required is large, the volume and weight of the photographic device are large, and the cost is high
