Title: Application of the Structure from Motion Method in Active Tectonics Research: A Case Study Over the Altyn Tagh Fault
Abstract: High-precision and high-resolution topographic data are the basis of active tectonics study. The rapid development of photogrammetry method provides an economical and effective means for obtaining such topographic data. Particularly in recent years, as the rapid development of computer vision theory and automatic feature-matching algorithm, a 3D reconstruction technique called "Structure from Motion" (SfM) was introduced into the photogrammetry method, greatly improving the flexibility and efficiency of the traditional photogrammetry method. In this study, we examined the applicability of SfM photogrammetry method in modeling the topography of fault zone by using images acquired with a low-cost digital camera mounted on an unmanned aerial vehicle (UAV) over the Altyn Tagh fault, which is located at the northern boundary of the Tibetan Plateau. The results show that the SfM photogrammetry method can obtain high-resolution topographic data of the fault zone, demonstrating its great potential in quantitative research of active tectonics.
