摘要
地貌实景三维建模在地质勘探、自然遗产保护等领域都具有重要应用。但是常规摄影测量缺乏地形自适应的摄影航线规划,采集的影像分辨率差异大,造成影像所构建的三维模型精度偏低,不能满足日益精细化的三维建模需求。因此,本文将倾斜摄影和贴近摄影技术相结合,拟增加近距离地貌影像数据采集,以获取更加细致的地貌特征,从而建立更加真实、精细的地貌实景三维模型。
Geomorphic realistic 3D modeling has important applications in geological exploration,natural heritage protection,and other fields.However,conventional photogrammetry lacks of terrain adaptive photographic route planning,and the resolution of the acquired images is very different,resulting in the low accuracy of the three-dimensional model constructed by the images,which can not meet the increasingly refined three-dimensional modeling needs.Therefore,this paper will combine the oblique photography and close-range photography technology to increase the close-range geomorphic image data acquisition to obtain more detailed geomorphic features,so as to establish a more realistic and refined three-dimensional geomorphic realistic model.
