摘要
倾斜摄影测量技术为大规模城市实景三维模型数据快速生产提供了有效的解决途径。本文面向大规模城市实景三维建模生产需求,对三维数据生产中关键技术进行了分析和研究,以北京六环范围实景三维建模实践为例,基于Context Capture Center建模软件,提出了实景三维模型数据生产的技术流程,对实景三维建模生产效率、三维模型成果精度进行了分析和总结。
The technology of oblique photography provides an effective solution for the rapid production of large-scale city real 3D model data.Based on the production demand of large-scale city real 3D modeling,this paper analyzes and studies the key technologies in 3D data production.Take the practice of Beijing sixth ring road real 3D modeling as an example,based on the Context Capture Center modeling software,the technical process of 3D model data production is put forward,and the production efficiency of 3D modeling and the accuracy of the 3D model results are analyzed and summarized.
