摘　　要：随着近年来新型基础测绘工作的展开,更多新型测量仪器得到应用展示的空间,其中无人机和三维激光扫描仪因其便捷性和时效性被广泛应用。在常规工程前期快速获得土石方量是后续工程进行的前提。传统方法费时费力,且在测绘现场需要考虑作业人员的安全。将无人机的效率与三维激光扫描仪、背包式扫描仪的局部高精度相结合,对上海某地区进行大范围土石方测量,并进行了精度对比。实验表明,在精度要求相同的情况下,基于新型基础测绘的方法比传统方法更高效和安全。With the development of new basic surveying and mapping work in recent years,more new measurement instruments have been applied and displayed,among which UAV and 3D laser scanners are widely used because of their convenience and timeliness.In the early stage of conventional engineering,quickly obtaining the amount of earthwork is a prerequisite for subsequent engineering.The traditional method is time-consuming and laborious,and the safety of operators needs to be considered in the surveying and mapping site.We combined the efficiency of UAV with the local high-accuracy of 3D laser scanner and backpack scanner,carried out a large scale earthwork measurement in a certain area of Shanghai,and compared the accuracy.Experimental result shows that when the accuracy requirements are the same,the method based on the new basic surveying and mapping is more efficient and safer than the traditional methods.
