Abstract：Engineering surveying is a fundamental aspect of the implementation phase of construction projects,and its efficiency and accuracy have significant impacts on project progress,cost,and quality control.To promote the application of intelligent surveying and mapping technologies in construction projects,a large urban complex project adopted a surveying method that combines drone surveying with WebGIS.Relying on this project,the article discusses the basic principles of intelligent drone surveying technology,with a focus on analyzing the workflow of drone intelligent surveying image acquisition and its application in earthwork measurement.The study shows that the elevation measurement error of drone intelligent surveying technology is only 3 cm,and the earthwork volume measurement error is 0.5%,which can meet the precision requirements for temporary earthwork stockpile measurement in construction projects.Compared with the traditional GNSS-RTK method,drone intelligent surveying technology can save about 50%of labor and increase surveying efficiency by about 75%,demonstrating a significant advantage in surveying efficiency.
