| Abstract: | This study reconstructs high-precision surface 3D models using aerial imagery derived from unmanned aerial vehicle (UAV) by the method of structure from motion (SfM). The geometry of the offset channels are obtained by the fusion of automatic extraction and manual visual interpretation. Based on the retrodeformation of geomorphologic marker, the offset distance is measured by lateral displacement calculator (LaDiCaoz). This paper is focused on tectonics geomorphology of the middle section of the Altyn-Tagh fault, and measures nearly 100 sets of geomorphological offset data. The result indicates that there may be 5 paleoearthquakes in the middle section of the Altyn-Tagh fault. |
