无人机（Unmanned Aerial Vehicles，UAV）正成为一种有效的高分辨率图像采集工具，用于从地面难以到达或观察的地方。在这项研究中，作者在2016年日本熊本地震造成的各种破坏地点进行了无人机飞行，如表面断层，推翻墓碑，山体滑坡，倒塌的建筑物和桥梁。无人机飞行捕获了高分辨率的视频片段和照片，并使用它们，基于SfM（运动恢复结构）技术开发了三维（3D）模型。所建立的模型能够形象地描述损伤情况，并通过与航片和现场实测结果的对比，对模型的精度进行了评估。
Unmanned Aerial Vehicles (UAVs) are becoming an efficient tool of high-resolution image collection for the places that are difficult to access or observe from the ground. In this study, UAV flights were carried out by the authors over various damage sites due to the 2016 Kumamoto, Japan earthquake, such as surface faulting, overturned tombstones, landslides, collapsed buildings and a bridge. The UAV flights captured high-resolution video footages and photos, and using them, three-dimensional (3D) models were developed based on a SfM (Structure-from-Motion) technique. The developed models could depict the damage situations vividly, and the accuracy was evaluated through comparison with aerial photos and field measurement results.
