摘要
无人机倾斜摄影可在短时间内快速获取地面可视化全景影像数据,尤其适合屋顶及地面数据获取;移动三维(3D)激光扫描可以灵活高效地获取地上地下一体三维激光点云及影像数据.本文通过空间同名异构公共点进行转换、匹配,进行激光点云与无人机倾斜数据融合,从而获取无死角的三维空间可视化数据,快速绘制规划竣工二维矢量线画图.结合具体案例,以三维激光点云为基准点云,对同名公共点通过平移、旋转进行点云配准获得融合点云,将获取的融合三维可视化数据与全站仪获取的坐标数据进行对比,分析融合数据的精度和影响因素供参考,为快速获取规划竣工所需矢量线画图提供新的途径.
Abstract
Oblique photography of unmanned aerial vehicles(UAVs)can quickly obtain visual panoramic ground image data in a short period of time,especially suitable for rooftop and ground data acquisition.Mobile three-dimensional(3D)laser scanning,with its flexibility and efficiency,can obtain integrated 3D laser point clouds and image data above and below ground.After converting and matching heterogeneous common points with the same name in space,laser point clouds and oblique data of UAVs were fused to obtain 3D spatial visualization data without dead corners and quickly draw two-dimensional(2D)vector line drawings for completion planning.Based on specific cases,a 3D laser point cloud was used as the reference point cloud,and the fusion point cloud was obtained by translating and rotating a common point with the same name to register the point cloud.The obtained fused 3D visualization data was compared with the coordinate data obtained from the total station,and the accuracy and influencing factors of the fusion data were analyzed for reference.This provided a new solution for quickly obtaining the vector line drawing required for completion planning.
