Application of DP-Modeler Fine Modeling in Water Conservancy Engineering Surveying
The oblique model produced by oblique photogrammetry has been applied to most water conservancy projects,but the principle of the existing oblique model production is based on the extraction and matching of image feature points to achieve automatic modeling,which has a high degree of automation,resulting in poor modeling effect of true 3D modeling,so it is necessary to modify the oblique model and monomer modeling to make up for this shortcoming.Based on the production needs,this paper uses DP-Modeler software to explore a more effective working method and process from three aspects:modeling principles and processes,model modification,and monomer reconstruction,so as to make the 3D model of hydraulic engineering more refined and usable.This method is practical and operable,in order to have certain reference significance for the construction of 3D models of other water conservancy projects.
