Application of 3D laser scanning technology in earthwork survey

实现三维激光扫描技术在土方量测量中的应用,从三维激光扫描的原理到扫描的土方测量方法,包括土方测量的准备工作、三维激光数据采集工作,以及土方测量数据处理和土方量计算方法,并结合实际土方工程测量,对比分析了三维激光扫描技术、全站仪测量技术以及RTK测量技术在土方工程中的测量结果。研究结果表明,相较于全站仪测量技术以及RTK测量技术,三维激光扫描技术的土方量的测量方法拥有更佳的精确度,其与实际情况的误差大小仅为前述方法的1/5及1/3左右,且十分接近实际土方量,同时数据的稳定性较好。

This paper realizes the application of 3D laser scanning technology in earthwork measurement,from the principle of 3D laser scanning to scanning earthwork measurement method,including the preparation,3D laser data collection,and earthwork calculation method,and combined with the actual earthwork measurement,the comparative analysis of 3D laser scanning technology,total station measurement technology and RTK measurement results in earthwork technology.The results show that compared with the total station measurement technology and RTK measurement technology,the earthwork measurement method of 3D laser scanning technology is more accurate,and the error with the actual situation is only about 1/5 and 1/3 of the aforementioned method,which is very close to the actual earthwork quantity,and the stability of the data is good.
