摘　　要：倾斜摄影测量生产的倾斜模型已能够应用在多数水利工程项目中,但现有倾斜模型生产的原理都是基于影像特征点提取和匹配来实现自动建模,自动化程度高,导致真三维模型建模效果不佳,因此需要对倾斜模型进行修饰以及单体化建模来弥补这种不足。基于生产需要,利用DP-Modeler软件,从建模原理与过程、模型修饰、单体化重构三方面来探讨一种更加有效的工作方法及流程,使得水利工程上的三维模型更加精细化、可利用化。此方法切合实际,可操作性强,对同类水利工程的精细化三维模型建设具有一定的参考借鉴意义。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.
