Abstract

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
