Abstract

This study focuses on urban architecture as the research subject and conducts a technical investigation into the construction of three-dimensional (3D) models of cities using high-resolution satellite stereo imagery. By acquiring high-resolution satellite stereo images within the study area, collecting control data or conducting field measurements for image control points, performing regional network adjustment, constructing 3D models, applying universal textures, and attributing properties to building base surfaces, we ultimately establish a city 3D model that meets Level of Detail (LOD) 1.3 precision. Through field measurements of certain proportions of building base surface elevations, building heights, and planar locations—followed by comparative analysis with the constructed city 3D model—we demonstrate that the model achieves LOD 1.3 accuracy requirements. This has significant reference value for both the presentation and application of urban 3D models. The primary objective of this research is to explore new technological methods in the construction of urban 3D models in order to enhance work efficiency and reduce production costs.
