摘　　要：近年来,数字城市在实景三维模型的基础上得到了广泛研究与应用。但是,传统三维建模手段难以满足现代数字城市更快速、更真实、更准确、更大规模的数据生产要求。本文以江苏省淮安市蒋坝古镇为例,开展快速构建城市精细化三维模型的研究,基于低空无人机倾斜摄影测量技术构建城市实景三维模型,利用几何造型方法对实景三维模型进行精细化加工。结果表明,采取的方案满足实景三维模型的应用需要,适合城市三维模型快速构建,对大规模三维模型数据生产具有一定的参考价值。In recent years,digital cities have been widely researched and applied on the basis of real-life 3 D models. However,traditional 3 D modeling methods are difficult to meet the requirements for faster,more realistic,more accurate,and larger-scale data production in modern digital cities. Taking Jiangba ancient town in Huai ’ an City of Jiangsu Province as an example,this paper completed the research of urban three-dimensional model,built a three-dimensional model of urban real-life based on inclined photogrammetry technology,and refined the real-life three-dimensional model by geometric modeling method. The results showed that the adopted scheme satisfies the application needs of the real-life 3 D model,and it was suitable for the rapid construction of large-scale regional urban 3 D models. It had certain reference value for the production of large-scale 3 D model data.
