无人机航测技术在市政工程施工地形建模中的应用OA

To address the issues of low efficiency and insufficient accuracy in traditional terrain modeling techniques for municipal engineering construction,this paper takes the municipal road network and supporting pipeline network project in a high-tech zone of a certain city as the research object,and systematically explores the application process and technical points of UAV aerial surveying technology in construction terrain modeling.By developing a targeted flight planning scheme,data acquisition for the study area was completed,and professional software was used for data preprocessing and the construction of a three-dimensional terrain model.The results show that the model has a planimetric position error of±0.12 m and an elevation error of±0.08 m,meeting the accuracy requirements for municipal engineering construction and providing a reference for terrain modeling in similar municipal engineering projects.
