基于无人机贴近摄影测量技术的古建三维数字化建模应用研究

Research on Application of 3D Digital Modeling of Ancient Architecture Based on Uav Nap-of-the-Object Photogrammetry Technology

以承启楼古建三维数字建模为例,介绍无人机贴近摄影技术基本原理、三维建模的技术流程,并对无人机贴近摄影测量在承启楼项目的具体实施过程进行详细介绍,从外业数据采集到内业建模处理,最终得到精细化三维模型成果,并对模型成果进行分析展示,精细还原古建纹理细节,解决了古建数字化问题,为古建数字化建档提供了新的方案。

This paper introduced the basic principle of uav nap-of-the-object photogrammetry technology and the technical process of 3D modeling,introduced the specific implementation process of UAV nap-of-the-object photogrammetry in Chengqilou 3D modeling project in detail,from the data collection to the modeling processing,finally obtained fine 3D model results,analysised and displayed the texture details of the model results,which provided a new scheme for the digital filing of ancient architecture.
