三维激光扫描仪在填海吹沙土方测量中的应用研究

The Application and Research of 3D Laser Scanner for Earthwork Measurement of Blowing Sand Reclamation

三维激光扫描仪因其为非接触式测量方式,能够在短时间快速获得高精度点云数据,在一些特殊地形地貌测量中具有广泛的应用价值.本文利用三维激光扫描仪以平潭岛地区的填海吹沙工程为案例,阐述了三维激光扫描仪的基本原理及在吹沙方量测算中的应用情况,并与全站仪数据采集的成果进行了数据对比,验证了三维激光扫描在吹沙地形测量中能够达到精度要求.

As a non-contact measuring instrument,3 D laser scanner can collect point cloud in a short time,and it can be applied in some special topographic and geomorphological measurements widely. This paper elaborates the principle of point cloud merging and registration in the special landform about blowing sand reclamation. By comparing the accuracy of result between total station and 3 D laser scanner,it proves that the 3 d laser scanner can be applied in the earthwork measurement of blowing sand reclamation. And compared with the results of total station,it proves that the 3 d laser scanning topographic survey in the blowing sand can meet the precision requirement of earthwork measurement.
