Abstract
The purpose of the study is to develop and test a method for measuring the volumes of three-dimensional objects in the coal industry, which makes it possible to improve the accuracy of the results and the speed of obtaining them. Compared to existing approaches to processing laser scanning data, it is proposed to use one and only one plane to create the base polygon of the object, place the base polygon and the dense point cloud in the world coordinate system. Testing the technique implemented in the web application on geometric primitives showed high accuracy and increased performance. Further, surveys of coal storages of various sizes were carried out in various ways – ground survey using total stations, aerial photography, airborne laser scanning. The laser scanning data were processed both in the traditional way and according to the method developed in the study. A high convergence of the results of this technique with standard approaches, as well as a fairly high degree of accuracy, is shown.
