摘要
随着测量技术的发展,获取土石方数据的手段日益多样。除了传统全站仪或RTK离散点获取方式,无人机机载LiDAR及三维激光扫描获取点云方式得到了日益广泛应用;与传统测量手段相比较,激光点云获取土石方数据增加了点密度,理论上可获得更好的测量结果。基于不同手段获取的点云数据,可采用不同的数据处理方法获取土石方测量结果,本文在讲述不同手段获取土石方测量数据的基础上,探讨点云数据密度与获取土方准确率的关系,并与传统方式进行精度比较,得到了一些有益结论,为基于点云的土石方量测量提供良好借鉴。
With the development of measurement methods, the methods of obtaining earthwork data are increasingly diverse. In addition to the traditional total station or RTK discrete point acquisition method, UAV tilt and three-dimensional laser scanning point cloud acquisition method has been increasingly widely used. Compared with the traditional measurement method, laser point cloud acquisition of earthwork data increases the point density, which can obtain better measurement results in theory. Based on the point cloud data obtained by different means, different data processing methods can be used to obtain the earthwork measurement results. This paper discusses the relationship between the point cloud data density and the accuracy of obtaining earthwork on the basis of different means of obtaining earthwork measurement data, and compares the accuracy with the traditional methods, and obtains some useful conclusions, which provides reference for the earthwork measurement based on point cloud.
