Point-Cloud Surveys and Geotechnical Assessments

摘要

QuarryDesign have long been at the forefront of the UK quarrying industry for their use of modern surveying techniques to produce exceptionally high-quality rock-face and soil-slope surveys, and for their interrogation of those surveys using specialist software to allow a better understanding of the geological and geotechnical properties of a wide variety of industrial mineral and aggregate quarries. Previous papers in QM introduced the relatively new (as then) technologies of long-range high-resolution LiDAR scanning (March 2011) and UAV-derived photogrammetric models (April 2014). Both survey techniques result in a point-cloud survey (a survey frequently comprising millions of points rather than the hundreds or thousands of survey points in a conventional survey).
