Three-dimentional spatial coordinate transformation based on least squares collocation

LI Xiao,YIN Hui(School of Geodesy and Geomatics,Wuhan University,Wuhan 430079,China)  
Taking into the common points errors in solving unknown transformation parameters,this paper introduces a new method of spatial coordinate transformation based on the least squares collocation,which means the coordinates of common points are taken as random parameters,and the transformation parameters are taken as nonrandom parameters.By analyzing the experiment results,it indicates the new method is better obviously.
