摘要
针对小范围、低成本的实景三维建模,传统五镜头或两镜头倾斜摄影系统因载荷、成本、飞控等问题显得不合时宜。本文采用多旋翼无人机搭载单镜头相机,选用无人机管家软件设置飞行航摄控制参数,基于Smart3DCapture软件多视立体视觉算法(PMVS)和运动结构恢复算法(SFM)构建贵阳市花溪区某试验区实景三维模型。通过单点精度检验,符合大比例尺航空摄影测量内业规范要求。在房产测量、地籍测绘、模型展示等领域具有低成本、高效率、高精度优势。
For small areas,low-cost real-world 3D modeling,the traditional five-lens or two-lens tilt photography system is unsuitable due to problems such as load,cost,and flight control. The model 3D real-world in this article using a multi-rotor drone equipped with a single-lens camera,using UAV chamberlain software sets flight aerial control parameters,multi-view stereo vision algorithm (PMVS)and motion structure recovery algorithm (SFM) based on Smart3DCapture software. The result meets the requirements of the large-scale aerial photogrammetry industry standard by single point accuracy test.The method has low cost,high efficiency and high precision in real estate measurement,cadastral mapping,model display,etc.
