贴近摄影测量环绕式航线规划方法研究

Study on Surrounding Path Planning Method of Close-Up Photogrammetry

精细三维模型不仅能够记录建筑物的原始三维信息,还能够记录其纹理信息,可以为建筑物的重建、保护、展示、修缮等工作提供重要的基础数据。以日照市灯塔为例,在初始场景信息的基础上进行了无人机的环绕式航线规划,以此探索了贴近摄影测量技术在建筑物精细三维模型建设中的应用流程。研究结果表明:贴近摄影测量可以达到毫米级的地面分辨率精度,在建筑物的三维信息获取中取得了显著成效。

Fine 3D model can not only record the original 3D information of buildings,but also record their texture information.It can provide important basic data for the reconstruction,protection,display and repair.Taking the old lighthouse of Rizhao as an example,based on the initial scene information,the surrounding path planning of the UAV is carried out,and the application flow of the close-up photogrammetry in the 3D model construction of the buildings is explored.The results show that close-up photogrammetry can achieve millimeter-level ground resolution accuracy,and has achieved significant results in the acquisition of 3D information.
