摘要
三维数字模型能够客观形象的反应地形地物的客观特征。综合分析了使用基础数据、遥感影像、三维激光扫描和过程数据的三维建模方法。介绍了无人机倾斜摄影测量系统的组成,以及使用倾斜摄影测量技术进行三维建模的流程,并分析了三维建模过程中需要注意的问题。将无人机与倾斜摄影测量技术相结合,发挥无人机机动灵活、空域限制小、高效快速、成本低廉的特点和倾斜摄影测量技术快速准确、自动化程度高的特点,可以极大地促进实景三维建模技术的发展。
The three-dimensional digital model can objectively and objectively reflect the objective characteristics of terrain and surface features.Three dimensional modeling methods based on basic data,remote sensing images,3D laser scanning and process data are comprehensively analyzed.This paper introduces the composition of the unmanned aerial vehicle tilt photogrammetry system and the process of 3D modeling using the tilt photogrammetry technology,and analyses the problems that need to be paid attention to in the process of 3D modeling.Combining the unmanned aerial vehicle with the tilt photogrammetry,the characteristics of the UAV's maneuverability,the small space limit,the high efficiency and the low cost and the high speed and accuracy of the tilt photogrammetry can greatly promote the development of the 3D modeling technology of the real scene.
