For the urban 3D modeling which is the biggest problem in the construction of Digital City across the country extensively, this paper proposed a method of urban 3D modeling based on the results of oblique aerial images, which gains oblique images of the modeling area with the Oblique Photography Technique, combined the building texture and geometric model extracted in the image through the data preprocessing and the geometric model of existing buildings, and finally established a 3D model.%针对目前全国广泛开展的数字城市建设中最大的问题---城市三维建模，本文提出了一种基于倾斜航空影像成果的城市三维建模方法，即利用倾斜摄影技术获取建模区域的倾斜影像，经过数据预处理和已有建筑的几何模型，将影像中提取的建筑物纹理与几何模型相结合，最终建立三维模型。
