An Object-Oriented UAV 3D Path Planning Method Applied in Cultural Heritage Documentation

A novel object-oriented UAV path planning method significantly enhances the efficiency and accuracy of 3D reconstruction for cultural heritage documentation. By defining geometric classes on a coarse model and generating regular aerial strip units, the approach optimizes flight paths while avoiding obstacles, resulting in high-resolution images that faithfully capture textures. Applied to UNESCO World Heritage Sites like Ping Yao's Ancient City and the Yellow Crane Tower, this method outperforms conventional planning techniques, improving both flight efficiency and visual finesse of reconstruction results.
