摘要: 随着“实景三维中国”建设计划的推进,大规模、高精细的城市级实景三维生产需求日益增长。本文从顶层设计出发,结合倾斜摄影、激光扫描等技术,构建了面向城市级实景三维建设的全生命周期技术框架,并以成都市天府新区作为研究区域,验证了该技术架构的可行性。研究结果表明,最终的实景三维模型精度符合设计要求,表达质量符合要求,逻辑一致;在规范技术流程的同时,大幅节约了生产成本,同时也为其他城市的实景三维建设研究提供了参考。

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
