摘　　要：为探究无人机倾斜摄影技术在地质公园中应用的可行性和价值,通过对不同地区不同类型地质遗迹的实地航摄,采集和分析像片数据,利用Context Capture建模软件开展地质遗迹三维实景建模,探究实地航测和建模过程中重要参数设置和数据处理对内外业工作以及建模质量的影响,探讨模型数据在地质公园中的应用价值。结果表明,无人机倾斜摄影技术可以对地质遗迹进行真实的立体化展示,同时可以对地质遗迹特征参数进行高精度测量。结合Global Mapper等GIS软件,还可生成大比例尺高精度地形数据,为地质遗迹调查评价工作提供了新的技术手段和资料,为地质公园规划建设提供了可视化方案,为空间数据库和高精度三维实景公园建设提供了可能。In order to explore the feasibility and value of the application of UAV tilt photography technology in geoparks,through field aerial photography of different types of geological relics in different regions,the photo data was collected and analyzed,and the 3D real modeling of geological relics was carried out using ContextCapture modeling software.This paper explores the influence of important parameter setting and data processing on internal and external work and modeling quality in field aerial survey and modeling,and discusses the application value of model data in geoparks.The results show that the UAV tilt photography technology can display the geological relics in 3D and measure the characteristic parameters of geological relics with high precision.Combined with GIS software such as Global Mapper,large scale and high-precision terrain data can also be generated,providing new technical means and data for geological heritage investigation and evaluation,visualization schemes for geopark planning and construction,and possibilities for spatial database and high-precision 3D real scene park construction.
