application  of multivariate total least square  in three-dimensional coordinate transformation

  • for avoiding loss  of  accurac y caused by the  linearization  of  rotation matrix in  three-dimen-sional  coordinate  transformation  by the  total  least  squaretlsmethodthe multivariate total  leastsquaremtlsmodel  is  advanced.in order  to  evaluate  the  effect  of mtls on coordinate  transformation various  experiment  schemes  set  compared with the tls al gorithm.he  impacts  of  rotation angleand scale  factor  on solution precision  are  anal yzedand conclusions based on the  experimentresults  asfollowingin  the  condition of  coordinate  transformation with a bi gger  rotation angle  or  under  independent  equal  precision observationthe  solution precision of mtls is  better  than  the one of tlses peciall y the mtls method does not need  iterative  calculation and can be used  for  coordinate  transformation with any scale  factor
