Abstract

Abstract: The advancement of the “Real 3D China” construction plan is increasing demand for large-scale, high-definition city-level real 3D production. Starting with the top-level design and combining it with oblique photography, laser scanning, and other technologies, this research builds a technical framework for the entire life cycle of urban-level real scene 3D construction, using Chengdu's Tianfu New district as the research area to validate the technical framework's feasibility. The research results indicate that the final 3D real-scene model's accuracy meets the design requirements, the expression quality meets the requirements, and the logic is consistent. Standardizing the technical process has reduced production costs significantly, and it also served as a reference for real-world 3D construction research in other cities.

Key words: real scene 3D model, oblique photography, laser scanning, city level
