The post-mining remediation of former activities must be reconciled with ongoing mining operations and the forward-looking planning of future uses. A precise understanding of the status of underground cavities is a fundamental prerequisite for the successful and targeted planning of future forms of use. These include the preparation and operation of underground pumped storage power plants and the final disposal of highly radioactive waste at a site yet to be found. The use of three-dimensional acquisition methods is a central aspect of addressing these complex tasks. The objective of this study is to investigate the use of photogrammetric methods under challenging, practical conditions. In contrast to conventional geotechnical surveying methods, this image-based surveying method employs high-resolution measurement images to record the entire cavity. This study aims to develop an interdisciplinary approach to cavity registration using the structure from motion (SFM) technique. The SFM method is based on the automated extraction and matching of identical features in an unstructured image set. It therefore enables the use of commercially available cameras and even the use of mobile capture systems such as smartphones. The investigation of key parameters influencing the photogrammetric evaluation and the products to be generated, such as point clouds and 3D models, forms the basis for the development of optimization approaches as part of a holistic acquisition methodology. This will be evaluated quantitatively and qualitatively in the course of three case studies in a simulated mine in the mining building of RWTH Aachen University, in the former lead ore mine Grube Wohlfahrt and in the Konrad repository mine site. Together with the promising results of the surveying evaluation, this thesis concludes with a proposal for an optimized, integrated cavity registration in the form of a flow chart. Finally, its application in view of future interdisciplinary challenges is discussed. LB - PUB:(DE-HGF)11 DO - DOI:10.18154/RWTH-2024-06133 UR - https://publications.rwth-aachen.de/record/988269 ER -
