倾斜摄影测量在复杂空域及地形条件下高精度三维建模研究

Research on high precision 3D modeling of oblique photogrammetry in complex airspace and terrain

近年来,随着科学技术水平的不断提高,通过倾斜摄影可进行三维建模及模型立体量测,已经在城市三维数据获取方面得到广泛应用,但在复杂空域或地形条件下大比例尺测图中的应用还较少。本文利用大棕熊飞机,搭载CityMapper-2S混合型摄影测量系统在昆明机场附近区域开展高精度倾斜摄影数据获取及处理研究,然后在内业利用Context Capture软件进行空三加密和三维建模,最后采用外业实测检查点对三维模型的精度进行验证,以此推断是否可以应用于该区域大比例尺测图中。

In recent years,with the continuous improvement of the level of science and technology,3 D modeling and model measurement can be carried out by oblique photography,which has been widely used in urban 3 D data acquisition,but it is less used in large-scale mapping under complex airspace and terrain conditions.In this paper,we use the big brown bear aircraft and citymapper-2 s hybrid photogrammetry system to carry out high-precision tilt photography data acquisition and processing research in the area near Kunming airport,then uses the context capture software to carry out space three-dimensional encryption and three-dimensional modeling.Finally,we uses the field measured checkpoints to verify the accuracy of the three-dimensional model,so as to determine whether it can be applied to large-scale mapping.
