This research demonstrates the integration of UAV LiDAR and photogrammetry for effective village heritage documentation, suggesting new conservation strategies.
Traditional village heritage encompasses multi-scale complexities, ranging from macro-level landscapes to micro-scale architectural details, which traditional survey methods often fail to capture adequately. This study constructs an "Air-Ground Coordination" framework that combines UAV oblique photogrammetry, UAV LiDAR, micro-UAVs, and both handheld and metrology-grade 3D laser scanning. By analyzing five digital surveying techniques through practical case studies, the research demonstrates the strengths and integration of multi-source methods for diverse village settings. The proposed "dynamic hierarchical collection, multi-device collaborative operation, and cross-scale integration" digital documentation system advances heritage conservation from static records to systematic, multi-layered digital twin management, offering a potential approach for future preservation efforts.
