| 摘 要： | 传统土石方测量方式基于DEM土石方算法,利用全站仪或者RTK获取地面离散点的高程,将地形模拟为高度不一的棱柱来计算方量.基于离散点的TIN三角网计算方法,其精度往往取决于离散点采集密度,过密的离散点采集大幅度增加了外业测绘的工作量.针对传统测量方式的不足,本文将三维激光扫描技术应用于土石方测量中,对站式扫描仪和手持扫描...

| Abstract: | The traditional method of earthwork measurement is based on DEM earthwork algorithm,which uses total station or RTK to obtain the elevation of discrete points on the ground,and simulates the terrain as prisms with different heights to calculate the earthwork.The accuracy of TIN trigonometric network calculation method based on discrete points often depends on the collection density of discrete points,which greatly increases the workload of field surveying and mapping.In view of the shortcomings of traditional measurement methods,this paper applies 3D laser scanning technology to earthwork measurement,verifies the accuracy of station scanner and hand-held scanner used in earthwork measurement,compares 3D scanning with traditional measurement methods,analyzes the advantages and disadvantages of the two scanning methods,and provides a new reference for earthwork measurement. |
