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。

Abstract: In recent years, digital cities have been widely researched and applied on the basis of real-life 3D models. However, traditional 3D 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 3D model, and it was suitable for the rapid construction of large-scale regional urban 3D models. It had certain reference value for the production of large-scale 3D model data.

Key words: digital city, inclined photogrammetry, geometric modeling, real-world 3D modeling, model modification
