摘　　要：我国古桥数量众多,但相关档案信息匮乏,古桥细节信息极少.为解决古桥数据缺乏的问题,提出基于消费级无人机的古桥三维重构,首先介绍了消费级无人机的选型配置,同时开展了相机参数的解算工作,研究了合理的飞行路径,讨论了三维重构的算法.最后以上海的洪德桥为例,进行了算法等建模策略的实践,进行了精度与误差分析.实验结果表明,基于消费级无人机的古桥三维重构具有可操作性、完整性和高还原度,宜作为档案资料进行保存,最终实现古桥的数字化和信息化.There are a large number of ancient bridges in China.However,documentations of ancient bridges are scarce,and the details of them are rare.To provide solution to the lack of data on ancient bridges,3D reconstruction based on consumer-grade unmanned aerial vehicle was proposed.Configuration of consumer-grade unmanned aerial vehicle was first introduced.Parameters of the camera were resolved.Reasonable flight path was then considered.Algorithms of 3D reconstruction was studied.Hongde Bridge in Shanghai was experimented,resulting in an optimized 3D model with refine details.The results indicate that 3D reconstruction of ancient bridge based on consumer-grade unmanned aerial vehicle is feasible,complete and of high-fidelity.Thus,the model is particularly suitable for documentation of ancient bridge,leading to digitization and informatization of ancient bridges.
