Abstract:

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.

Key words: UAV, oblique photography, real 3D model, data processing cluster
