基于无人机倾斜摄影测量的三维地质建模研究进展

Research Progress of 3D Geological Modelling Based on the Unmanned Aerial Vehicle Oblique Photogrammetry

随着现代社会科学技术的不断发展,实景三维中国建设在当前社会生产活动中扮演着越来越重要的角色——逐渐成为数字经济的重要战略性数据资源和生产要素。而近年来兴起的无人机倾斜摄影测量技术通过与三维建模技术结合,在实现实景三维模拟方面表现出色。从无人机机型、三维地质模型和建模软件三个方面进行对比与总结。认为:在进行小范围测量或对航飞数据有高精度要求的情况下,建议优先选择旋翼无人机;Context Capture具有自动化程度高、一站式建模、操作简单、性能稳定的优点,在建立面模型时建议优先选择该软件。

With the continuous development of modern social science and technology,the construction of 3D China is playing an increasingly important role in the current social production activities-gradually becoming an important strategic data resource and production factor of the digital economy.In recent years,the UAV tilt photogrammetry technology,by combining with 3D modeling technology,has performed well in realizing 3D simulation of real scene.By combing the development status of UAV tilt photogrammetry technology and 3D geological modeling technology,the comparison and summary are made from three aspects of UAV models,3D geological models and modeling software.It is suggested that the rotary-wing UAV should be preferred in the case of small range measurement or high precision requirement of flight data.Context Capture has the advantages of high automation,one-stop modeling,simple operation,and stable performance.It is recommended to use Context Capture when building facade models.
