摘　　要：在VisualStudio2019开发环境下,利用C++中的MFC语言对DTM进行建模,并对其进行分析。本项目拟以K公路项目为研究对象,采用无人机采集的3D点云数据,进行DTM建模,实现完全和压缩两种方法的生成,并对其进行独立的土石方体积分析。通过与CASS软件的比较,证明了采用自动边界抽取的方法进行土方量的准确和高效,去除了DTM模型中的多余数据,对于提升DTM法的自动化水平具有十分重要的作用。In the VisualStudio2019 development environment,the use of C++MFC language to DTM modeling and analysis.This project intends to take the K-highway project as the research object,adopt the 3D point cloud data collected by UAV to conduct DTM modeling,realize the generation of complete and compressed methods,and conduct independent volume analysis of earth and rock.By comparing with CASS software,it is proved that the method of automatic boundary extraction is accurate and efficient to carry out earthwork quantity,and remove the redundant data in DTM model,which plays a very important role in improving the automation level of DTM method.
