Application of UAV aerial survey technology in urban and rural water supply renovation project
LI Kai-xin
Abstract：In view of the advantages of current unmanned aerial vehicle(UAV)aerial surveying technology in surveying projects,this study mainly elaborates on the technical process of UAV in municipal engineering topographic map measurement.Combining with the urban and rural water supply renovation project in a certain city,using drones to quickly collect data in the project area,and based on this,constructing a three-dimensional real-life model.By analyzing the accuracy of the model through actual measurement data,the research results show that the 3D model of the real scene produced by the oblique images collected by the drone has a certain degree of reliable accuracy,and the diversified data provided can provide technical support for the planning and design of subsequent municipal engineering.
