Aerial photography route planning method and system

Abstract

The invention discloses a route planning method, which comprises the following steps: acquiring a surface model of an object to be shot, and acquiring feature points from the surface model; acquiring a contour line of the object to be shot according to the feature points; and acquiring a route according to the contour line. The invention further discloses a route planning system. According to the route planning method and system, the route can be adaptively planned according to the contour of the object to be shot, the route planning method and system are high in adaptability for mountain photographing with complex terrains, the route planning method and system can be applied to other aerial photographing scenes such as buildings and the ground, meanwhile, aerial photographing can be directly carried out according to three-dimensional model data in the formats such as OSGB and OBJ. On one hand, the method can be matched with most models, and on the other hand, the matching degree of the route and the surface of the to-be-shot object is improved, and a solid foundation is provided for subsequent close-range imitation shooting.

Description

Technical field [0001] The present invention relates to drone aerial photography techniques, and specific to route planning methods and systems. Background technique [0002] When the aviation shoots for the mountain, complex terrain, large construction, etc., how to plan the aerial vehicle route to terrain and facade, so that the image resolution of the shooting is small, the overlap is stable, and is the target of the aerial field. [0003] The prior art imitationly or terrain follows photography to provide ideas for solving imaging resolution inconsistency, however, existing methods are usually on the ground, and the camera direction is vertical facing down, and there will be on the shooting of the slope Deformation, so the adaptation of complex terrain was not high. [0004] And existing imitation or terrain follows the photographic multi-channel model DEM, digital surface model DSM, point cloud data as elevation data, however the tilt model is typically stored as the 3D mode...

AI Technical Summary

Problems solved by technology

[0005] The technical problem to be solved by the present invention is that the existing terrain-following or terrain-following photography technology uses elevation models to generate terrain-following routes, which is not conducive to using other models to generate terrain-imitating routes. The purpose is to provide route planning methods and systems to solve the above-mentioned problems. question
