Iterative Method of Weight Constraint Total Least-Squares for Three-Dimensional Datum Transformation

    Graphical Abstract
    • Abstract
  • According to the traditional approach of three-dimensional datum transformation and classic least-squares(LS) theory,the weight constraint total LS(WCTLS) and mixed LS are introduced.A more reasonable model and the corresponding iterative algorithm are given.The example results show that the new model is more reasonable indeed and the more accurate parameters of datum transformation can be obtained with suitable weight assigned.
