基于倾斜摄影与BIM技术的土方量算方法
Earthwork Calculation Method Based on Oblique Photography and BIM Technology
摘要
Abstract
In order to solve the problems of high input,low efficiency and low accuracy of traditional earthwork calculation,we studied the earth-work calculation method combining UAV oblique aerial photogrammetry and BIM technology.Firstly,we used UAV oblique photogrammetry to obtain DEM data of the real surface.Then,we compared DEM data with the BIM model to check and analyze the construction quality of road en-gineering.The actual verification and analysis of a road engineering earthwork calculation project shows that the accuracy of this method is bet-ter than 1.4%,which can provide efficient detection for earthwork calculation and quality of road engineering under various schedules,and locate the position of out of tolerance.关键词
