ABSTRACT
With the acceleration of urbanization, the development and utilization of underground space has become an important approach to alleviating land resource constraints and optimizing urban functional layouts, while high-precision and comprehensive underground space surveying technologies have become critical in supporting this development. Conventional surveying methods suffer from issues such as low efficiency, high cost, and incomplete coverage in underground space data acquisition, thus necessitating the introduction of novel surveying technologies to meet practical demands. This study focuses on oblique photogrammetry technology, exploring its potential application in urban underground space surveying, aiming to achieve efficient and accurate mapping through multi-angle image collection and three-dimensional modeling. Data acquisition was conducted using drones equipped with oblique photogrammetry devices, combined with computer vision algorithms for three-dimensional reconstruction and semantic analysis of underground space structures. The experimental results indicate that this technology can significantly enhance the accuracy and efficiency of underground space surveying, while the generated three-dimensional models exhibit high geometric fidelity and texture detail, providing reliable data support for underground space planning, management, and disaster assessment. Additionally, this study innovatively proposes a deep learning-based method for underground space feature extraction, effectively addressing data matching and noise filtering challenges in complex environments, further improving the practicality and robustness of the model. Overall, the application of oblique photogrammetry technology in urban underground space surveying not only expands its technical boundaries but also offers new perspectives and technical references for research and practice in related fields, demonstrating significant theoretical value and application prospects.
