基于低空无人机倾斜摄影的三维模型构建

Construct 3D Model Based on Low-altitude UAV Oblique Photography

利用低空无人机倾斜摄影测量技术构造的真实三维模型对重庆万州狮子头危岩进行地质灾害监测,探讨倾斜摄影测量技术在危岩监测、危岩整治,灾情评估等方面的应用。结果表明,倾斜摄影测量技术在地质条件复杂的地区完成数据的获取与处理、三维建模和应用分析方面具有数据快速获取、处理,模型真实可量测等优势;利用倾斜摄影测量技术生成的真实三维地表模型、数字正射影像图和数字高程模型数据可以为危岩整治工程中的堆填土方量提供直观、翔实的基础数据和统计分析数据。

This paper,by using a low UAV photogrammetry technology structure of the tilt real 3 D model for geological hazards monitoring of chongqing wanzhou lion a dangerous rock,and further explore the tilt photogrammetry technology application in dangerous rock renovation.The results showed that the tilted photogrammetry technology in complex geological conditions of complete data acquisition and processing,has obvious advantages in3 D modeling and application analysis;Using tilt photogrammetry technology to generate real 3 D surface model,the Numbers are projective images and digital elevation model data for the renovation of dangerous rock fill earthwork quantity provide intuitive,the basis of detailed data and statistical analysis of data.
