无人机近景摄影支持下的老旧小区改造

Reconstruction of Old Community Support by UAV Close-range Photography

无人机摄影测量广泛应用于城市服务、工程测量、应急救灾、公共安全、林业保护等方面。本文结合实际工程经验,对多旋翼无人机近景摄影生成的三维模型进行研究,探索了一套应用于老旧小区改造的平面图、立面图制作方法,利用人工实测和三维激光扫描技术,验证了基于无人机近景摄影生成的平面图、立面图的精度和质量,为后续老旧小区改造项目的基础数据获取提供新的思路。

UAV photogrammetry is widely used in urban service,engineering survey,emergency relief,public safety,forestry protection and so on.Combined with practical engineering experience,this paper studies the 3D model generated by multi-rotor UAV close-range photography,explores a set of production methods of plan and elevation used in the reconstruction of old community,and verifies the accuracy and quality of plan and elevation generated based on UAV close-range photography by using manual measurement and 3D laser scanning technology,it provides new ideas for the basic data acquisition of subsequent old community reconstruction projects.
