摘要

As to calculating the amount of quarry exploitation, there are some disadvantages for traditional methods such as small data volume, low accuracy, and difficult access to data for complex topography.Comparatively, using laser point cloud data exploitation of quarry is of great significance.Lizhuang quarry is chosen as the object of study, then the point cloud data is obtained by using Leica C10, and the cloud data is preprocessed by Cyclone software, for which the data is compressed by Geomagic software.Then, the exploitation amount of quarry is calculated using Cyclone, HD-3LS-SCENE, CASS software respectively, and the result is compared in detail.Research result indicates that three kinds of software can meet the project demand.Computation accuracy based on the Cyclone software is the highest, while the accuracy by using CASS software is rapid and available.According to the comparative study of various performance indexes of the software, the effective calculation method of quarry mining amount is determined.%采石场开采量计算,由于传统测量方法存在获取数据量少、精度低、复杂地形获取数据困难等问题,利用激光点云数据计算采石场开采量具有重要的研究意义.选择李庄采石场作为研究对象,利用徕卡C10获取点云数据,运用Cyclone软件对点云数据进行预处理,Geomagic软件对预处理数据进行精简.采用Cyclone,HD-3LS-SCENE,CASS软件对开采量分别进行计算,详细对比分析计算结果.研究结果表明:三种软件可满足工程需要.Cyclone软件计算精度最高,CASS软件操作快捷方便.根据软件多种性能指标的对比研究,确定采石场开采量行之有效的计算方法.
