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。
The measurement of earthwork volume is an important aspect of engineering surveying.Traditional methods for measuring earthwork volume primarily rely on total stations and GPS-RTK,which are inefficient and costly,failing to meet the demands of modern construction projects for informatization,high efficiency,and low cost.Taking the construction of a power plant in the Lingang area of Shanghai as an example,this paper uses drone aerial surveying technology for earthwork volume measurement.The two-dimensional images collected by the drone are processed and a three-dimensional model is generated.On the basis of the three-dimensional model,point cloud files are extracted and refined,and Cass9.1 software is used to calculate the earthwork volume.The calculated earthwork volume is compared with the volume measured by GPS-RTK,yielding measurement results that meet the requirements of engineering surveying standards.
