贴近摄影与倾斜摄影测量技术融合在地质灾害调查中的应用

Application of fusion of proximity photography and obliquephotogrammetry in geological hazard investigation

传统的地质灾害调查中以人员实地调查为主,不仅工作效率低、而且工作区多为复杂地形,为地质灾害调查带来了挑战,使地质工作变得较为危险。本文以探究精细化三维模型构建技术在地质灾害调查中的应用为目的,融合贴近摄影与倾斜摄影测量技术,通过采集工作区多视影像,以及对灾害点贴近摄影,融合构建精细化模型,在此基础上进行地质灾害解译。经案例证明,贴近摄影与倾斜摄影测量融合技术构建出高分辨率、高精度地质灾害底层精细模型,在地质灾害应用中效果明显,大大提高了地质灾害调查效率。

The traditional geological disaster investigation mainly focuses on the field investigation 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 3Dmodel 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 technology 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 disaster application and greatly improves the efficiency of geological disaster investigation.
