【摘要】：鉴于传统的航空和卫星遥感手段主要针对城市建筑物顶部进行模型重建,而对地物侧面的三维重建一直缺少有效的解决方法,该文提出一套自动化实景三维模型生产流程和成果质量检测方法。利用倾斜摄影倾直两用低空相机技术,分别研究大区域高精度多视影像的获取、提高空中三角测量精度、城市实景三维模型构建等关键技术环节,并据此对全市数据成果进行了相应的分析,为倾斜摄影城市实景三维模型的生产提供参考和借鉴。
[Abstract]:Whereas the traditional aerial and satellite remote sensing methods are mainly aimed at the reconstruction of the top of urban buildings, there is a lack of effective solution to the 3D reconstruction of the surface. This paper presents a set of automatic real scene 3D model production flow and quality inspection method. By using tilting camera technology, the acquisition of high-precision multi-view images in large area is studied to improve the accuracy of aerial triangulation measurement. Based on the analysis of the data of the whole city, this paper provides a reference and reference for the production of the 3D model of slanting photography city.
