ABSTRACT
Island topographic mapping, as a critical foundation for marine resource development and environmental protection, plays a significant role in the sustainable development of coastal areas in terms of both accuracy and efficiency. However, traditional surveying methods encounter numerous limitations when applied to complex terrains and inaccessible regions. This study focuses on the application potential and practical effects of oblique photogrammetry technology in island topographic mapping. By employing multi-angle image acquisition and 3D modeling techniques, the research aims to enhance the precision and efficiency of data collection for island topographies. The methodology involves utilizing unmanned aerial vehicles (UAVs) equipped with oblique photogrammetry devices for data collection, combined with advanced technical processes such as bundle adjustment, point cloud generation, and digital elevation model (DEM) construction, to achieve comprehensive desc riptions of target island terrains. Through case analysis of a representative island, the results demonstrate that this technology significantly improves the resolution and coverage of topographic mapping while substantially reducing labor costs and time consumption. Additionally, the study proposes a quality assessment method based on multi-source data fusion, effectively addressing issues of data loss caused by occlusion or uneven lighting. A key innovation of this research lies in integrating oblique photogrammetry technology with the unique geographical environment of islands, overcoming the constraints of traditional surveying methods in complex terrains and providing a replicable technical approach for similar scenarios. The findings not only validate the feasibility and superiority of oblique photogrammetry technology in island topographic mapping but also establish a theoretical and practical foundation for further research in related fields.
