无人机倾斜摄影测量技术作为新技术在实景三维建模领域得到了广泛的应用。分析了倾斜摄影测量技术的基本原理、系统组成,给出了基于无人机倾斜设计技术的实景三维模型的技术流程与方案。选取河南焦作云台山红石峡森林景区为试验区,按照相关技术流程与方案制作了该地区的实景三维模型,模型真实表达了旅游景区的实际自然风貌、人文等特征,通过浏览模型便可以达到身临其境的感觉,该实景三维模型数据可作为旅游景区规划、景区各种自然现象仿真、开发智慧管理系统等的基础数据与依据,具有巨大的市场价值与应用前景。

The photogrammetric technology of unmanned aerial vehicle (UAV)has been widely used in the field of three-dimensional modeling as a new technique method.This paper analyzes the basic principle and system composition of the tilt photogrammetric technology and gives the technical flow and scheme of the real three-dimensional model based on the unmanned aerial vehicle tilt design technology.Taking the Yuntai Mountain Hongshi gorge Forest Scenic Area in Jiaozuo,Henan as the experimental area,the three-dimensional model of the area is made according to the technical process and scheme given in this paper.The model truly expresses the natural features of the scenic spots and the characteristics of the humanities,and can reach the feeling of the real scene by browsing the model,the real three-dimensional model can be used as the basic data and basis for the planning of tourist attractions,the simulation of various natural phenomena in scenic spots,and the development of the intelligent management system.It has very great market value and application prospect.
