| Abstract: | With the continuous expansion of China's railway construction scale, the demand for geological disaster monitoring along the railway is also gradually increasing. This paper proposed a railway geological hazard monitoring method based on unmanned aerial vehicle photogrammetry, targeting the characteristics of railway geological hazards. The paper elaborated on the drone data acquisition process and data processing technology, conducted on-site surveys of a certain railway section during operation, generated digital terrain results, and comprehensively interpreted digital terrain results for areas with geological disaster risks. The results indicate that drone photogrammetry technology can effectively monitor geological disasters along the railway, providing scientific and reliable data support for railway operation safety. |
