Application of fusion of proximity photography and obliquephotogrammetry in geological hazard investigation
The traditional geological disaster investigation mainly focuses on the field investiga-tion of personnel,which not only has low efficiency,but also the work area is mostly complex terrain,which brings challenges to the geological disaster investigation and makes the geological work more dangerous.The purpose of this paper is to explore the application of refined 3D model construction technology in geological disaster investigation,and to combine proximity photography and oblique photogrammetry technology,through collecting multi-view images in the working area and close photography of the disaster point,to construct a refined model,and on this basis to interpret geological hazards.It has been proved by the case that the fusion tech-nology of proximity photography and oblique photogrammetry can build a high-resolution and high-precision geological hazard bottom fine model,which has obvious effect in geological dis-aster application and greatly improves the efficiency of geological disaster investigation.
