城市高精度实景三维单体模型建设及应用
Construction and application of high-precision three-dimensional monomerization model for urban scenes
【摘要】 倾斜摄影测量技术可以实时、综合感知大尺度、高精度的复杂城市场景,在获取正射影像的同时获得真实的立面纹理信息,为城市实景三维模型建设提供保证。本文分析了城市三维单体模型测量基本技术,按照城市要素类型对单体化模型进行分类,研究了二维与三维数据的融合方式,其精细单体化成果在广州市白云区665 km~2城市实景三维模型建设中得到应用,在提高工作效率的同时降低了外业劳动强度。
【Abstract】 Oblique photogrammetry can perceive complex urban scenes with large scale and high-precision in a real-time and comprehensively. Furthermore,the technology obtains real facade texture while acquiring an orthograph, which guarantees the construction of three-dimensional models of urban scenes. This paper analyzes the necessary technology of urban three-dimensional monomer model measurement,and classifies the monomer model according to the types of urban elements by studing the fusion of twodimensiona and three-dimensiona data. The fine monomer results have been applied in the construction of 665 km~2 urban threedimensional model in Baiyun District,Guangzhou. It has been importantly used in the construction of the models,which not only improves work efficiency,but also reduces field labor intensity.
