摘要
基于Visual Studio 2019平台,采用C++的MFC语言编程,实现了DTM模型边界自动提取。以宜春至井冈山高速公路宜春三阳至新田段新建工程为例,使用无人机获取了三维点云数据并建立了DTM模型,创建了完整边界与紧缩边界并分别计算了土方量。将计算结果与CASS软件计算结果进行对比分析,结果表明:使用边界自动提取方法计算土方量准确、高效,去除了DTM模型中的冗余数据,对提高DTM法计算土方量的自动化程度有重要意义。
Based on the platform of Visual Studio 2019, the MFC language of C++ is used to realize the automatic boundary extraction of digital terrain model(DTM). Taking the new project of Sanyang to Xintian section of Yichun to Jinggangshan Expressway as an example, 3D point cloud data was obtained by UAV and DTM model was established. The complete boundary and the compact boundary were built, the earthwork volumes were calculated respectively. The calculation results was compared with those by CASS software. The results show that the earthwork calculated by the boundary automatic extraction method is accurate and efficient. The redundant data by DTM model is removed. It is great significant to improve the automation of the earthwork calculated by DTM method.
