摘要
本文指出复杂地形实景三维建模是地理信息科学和计算机视觉领域的研究热点之一,而传统倾斜摄影测量方法难以精确重建复杂地形细节特征。本文提出并研究了利用无人机摄影测量与地面近景影像相结合开展复杂地形精细化三维模型方法。实践表明,本文提出的多摄影测量技术方法构建的精细化实景三维模型可视化效果好且精度高,可以有效解决地形高差等复杂地貌条件对实景建模质量影响。
This paper points out that the 3D modeling of complex terrain is one of the research hotspots in the field of geographic information science and computer vision,but the traditional oblique photogrammetry is difficult to accurately reconstruct the detailed features of complex terrain.In this paper,the method of fine 3D model of complex terrain is proposed and studied by combining UAV photogrammetry with ground close-up image.The practice shows that the detailed 3D model constructed by the multi-photogrammetry technique proposed in this paper has good visualization effect and high precision,and can effectively solve the impact of complex landform conditions such as terrain height difference on the quality of real scene modeling.
