摘要

用徕卡扫描站II型三维激光扫描仪对相邻多工位目标波段进行旋转扫描,获取每个旋转位置的三维点云模型。对相邻的多站点序列云模型进行配准,获取对应点。然后将点云模型与单条航空三角测量理论相结合,获取同一坐标系下的云模型坐标,对模型进行非线性校正,排除模型组合带来的累积误差,完成多站点云模型连续条的高精度拼接。

Theoretical Research on Adjacent Multi-station Point Cloud Data Precision Combination in 3D Laser Scanning
Adjacent multi-station rotational scanning the target band with the 3D laser scanner ¿Leica Scan Station II¿, acquires the 3D point cloud models of every rotational position. Adjacent multi-station point seriate cloud models have been registered, acquires the correspondent points. Then combines point cloud models with the theory of single strip aerial triangulation, acquires coordinates of cloud models in the same coordinate system, nonlinear correction to the model, excludes the cumulative errors caused by model combination, completes a high precision splicing of more stations continuous strip of point cloud model.
