Abstract
This paper proposes a method for calculating the earthwork volume of irregularly designed surfaces based on multi-source data fusion.The method employs UAV oblique photography technology to rapidly capture images of riverbanks and build a 3D model of the current terrain;uses unmanned boats equipped with multi-beam sonar to collect underwater elevation data;acquires stratigraphic information through geological drilling and performs spatial interpolation using ArcGIS software;and constructs an irregularly designed surface model using Civil 3D according to design requirements.By fusing and overlaying above-water and underwater,as well as above-ground and underground existing terrain with the design surface,the spatial volume between each stratified layer and the design surface is automatically calculated based on a triangulated mesh volume surface.Results indicate that this method enables precise stratified calculation for six above-ground and underground layers,yielding accurate and reliable total earthwork volume results.Under complex design surface conditions,it allows efficient one-step calculation of the total earthwork volume,avoiding efficiency loss due to segmented data calculations and preserving the continuous undulations of the terrain.关键词
