摘要
本文研究GPS、地面三维激光扫描和倾斜摄影测量三种快速测算土石方的方法。GPS技术采用(方格网法和DTM法)两种方法测算,地面三维激光扫描采用激光点云建模测量体积的方法,倾斜摄影测量采用无人机影像建模测算体积的方法。研究结果表明:传统土石方测量方法,外业采集效率较低,测算的精度较低。采用三维激光扫描技术和倾斜摄影测量技术的方法,能够快速获取现场数据,提高土石方测量效率,精度相对于传统测算方法较高,对工程的工期、投资和规划设计都有着重要的意义。
In this paper,three fast methods of calculating earthwork are studied: GPS,three-dimensional laser scanning and tilt photogrammetry.GPS technology uses two methods (grid method and DTM method) to measure the volume.Laser point cloud modeling is used to measure the volume in ground three-dimensional laser scanning,and UAV image modeling is used to measure the volume in tilt photogrammetry.The results show that the traditional earthwork measurement method has low efficiency and accuracy in field acquisition.By using three-dimensional laser scanning technology and inclined photogrammetry technology,the field data can be obtained quickly,and the efficiency of earthwork measurement can be improved.The accuracy of the method is higher than that of the traditional method.It is of great significance to the construction period,investment and planning and design of the project.
