Laboratory Calibration of Phase-terrestrial 3D Laser Scanner

  • 摘要: 目的 建立了地面三维激光雷达系统误差的基本模型和参考模型,推导了平差模型。综合物理意义和经验的系统误差,利用实验室检校场,对相位式地面三维激光雷达FARO Focus3D进行了检校实验。实验得到了FARO Focus3D的系统误差改进模型,并验证了其有效性。

     

    Abstract: Objective Hardware-related system errors of terrestrial 3Dlaser scanner can be reduced or eliminatedby calibration.Basic model and reference model of terrestrial 3Dlaser scanner system errors were es-tablished.Laboratory calibration adjustment model was deduced.After the adjustment was comple-ted,exterior orientation elements,global coordinates of targets,coefficients of system error and ob-servations of corrected random error can be acquired.Considering both physically interpretable andempirically identified components,phase-terrestrial FARO Focus3Dself-calibration test was conduc-ted in a laboratory calibration room.The influence of the number and distribution of control points onthe residual distribution of observations and system error modeling were analyzed by calibration exper-iments.The modified model of FARO Focus3Dsystem errors was established.The effectiveness ofmodified model was proved.
