Working conditions in geological disaster areas are complex,mostly steep peak zone,easy rockfall landslide,bring a lot of inconvenience for geological disaster investigation work and increase the risk coefficients of traditional geological disaster investigation work. With the research and development of UAV photogrammetry technology,it has been applied in geological disaster investigation thanks to its high efficiency,low cost,high safety and diversified results. This paper describes a new type of refined modeling method by the application of Nap-of-the-object photogrammetry technology in geological disaster investigation. Through this technology,a re-fined three-dimensional model of a landslide disaster area is produced to interpret the detailed texture of the mountain and monitor the development of dangerous rock mass. Through the project experiment,the refined Nap-of-the-object photogrammetry technology meets the technical requirements of geological disaster investigation and realizes the transition from "field investigation" to "interpreta-tion investigation".
