Abstract

The invention provides a method for realizing landscape three-dimensional visualization based on a drone. The method comprises S1: acquiring images through a UAV remote sensing platform with a camera,carrying out photographing through relative altitude and a design route and setting an image overlap degree along heading and side directions, S2, carrying out inlaying and cutting according to the research area size, carrying out geometrical fine correction on the images, re-sampling the corrected images for identifying the landscape type, and mapping terrain texture of the produced drone imagesto a preproduced 3D model to obtain a simulative 3D surface model, S3, building a landscape model, and S4, overlaying spatial data of the 3D surface landscape and 3D objects on the ground to obtain 3D landscape in a study area and building 3D query and analysis functions according to the landscape cases of the study area. The method can acquire the remote sensing images with high resolution and improve the accuracy of 3D construction of the landscape.

Description

technical field [0001] The invention belongs to the field of 3D technology, and in particular relates to a method for realizing three-dimensional visualization of a landscape based on an unmanned aerial vehicle. Background technique [0002] With the continuous development of the information age, more and more applications require 3D scene models. At the same time, with the continuous development of information technology such as computer technology and the continuous popularization of various digital devices, the research on establishing 3D models of certain scenes or objects in the real world has gradually attracted the attention of researchers. 3D reconstruction has been widely used in architecture, gardens, virtual reality and other fields and has a very broad application prospect in the future. [0003] The methods of obtaining 3D models can be divided into three categories: first, directly use mathematical models or geometric modeling techniques to build models; secon...
