3D Model Production Solutions from Satellite Imagery for Different Application Scenarios

Abstract

3D reconstruction from satellite imagery has become a core application in the field of geospatial information technology today. Its inherent advantage of global coverage makes it indispensable in numerous fields, including but not limited to smart city construction, geographic navigation systems, virtual tourism, disaster response and management, and military and national defense. This paper compares different 3D models converted from satellite imagery, analyzing the characteristics and distinctions of various 3D models. It provides a comprehensive and in-depth analysis of various technical solutions for creating 3D models from satellite imagery. Through different comparisons, it offers a technical selection guide for 3D models in different application scenarios, enabling users to understand form, structure, and environmental changes more intuitively and deeply, and to prioritize between "visual fidelity" and "data availability".
