多源测绘技术在沿黄公路边坡地质灾害调查中的应用

Application of multi-source surveying and mapping technology in geological hazard investigation of slopes along the Yellow River highway

针对传统公路边坡地质灾害调查效率低、精度差、危险性高等不足,本文在沿黄公路开展了地质灾害调查试验,通过综合运用无人机倾斜摄影、车载移动测量、地面激光扫描仪、贴近摄影测量等多种测绘技术方法,研究生产中的工艺流程、技术参数及关键技术环节,形成了空地一体的解决方案,提高了边坡地质灾害调查的精度、效率及安全性。

In response to the shortcomings of low efficiency,poor accuracy,and high risk in traditional highway slope geological hazard investigation,geological hazard investigation technology experiments are carried out along the Yellow River highway.By comprehensively utilizing various surveying and mapping techniques such as unmanned aerial vehicle tilt photography,vehicular mobile measurement,ground laser scanner,and close proximity photogrammetry,the production process,technical parameters,and key technical links are studied to form a solution that integrates space and land,improve the accuracy,efficiency,and safety of slope geological hazard investigation.
