摘要
土方量测量是工程测量中重要的一部分,传统土方量测量,主要采用全站仪、GPS-RTK等方式,工作效率低、成本高,不符合现代工程建设信息化、高效率、低成本的要求.该文以上海市临港某电厂建设为例,将无人机航测技术用于土方量测量.对无人机采集的二维影像进行图像处理并生成三维模型,在三维模型基础上提取点云文件,把点云进行稀释,再利用Cass9.1软件计算出土方量,将计算出的土方量与GPS-RTK测量的土方量进行对比,得到符合工程测量规范要求的测量结果.
Abstract
Earthwork measurement is an integral part of engineering surveying.Traditional methods of earthwork measurement,primarily employing total stations,GPS-RTK,etc.,suffer from low efficiency and high costs,failing to meet the requirements of modern engineering construction for informatization,efficiency,and cost-effectiveness.This study takes the construction of a power plant in Lingang,Shanghai as a case study and applies UAV aerial survey technology to earthwork measurement.Two-dimensional images collected by the UAV undergo image processing to generate a three-dimensional model.Point cloud files are extracted from the three-dimensional model,and the point cloud is thinned out.Subsequently,Cass9.1 software is utilized to calculate the earthwork volume.The calcaulated earthwork volume is then compared with the earthwork volume measured by GPS-RTK to obtain measurement results that comply with engineering surveying standards.
