摘　　要：探讨了一种基于三维空间直角坐标系利用稳健抗差估计理论进行高精度坐标转换的方法。该方法能够克服个别公共点坐标精度较低或误差过大对坐标转换参数的影响,并解算出高精度坐标转换参数,从而达到高精度坐标转换的目的。通过算例分析表明该方法实用、有效。The transformation method of high system based on the use of robust estimation theory accuracy for a three-dimensional space rectangular coordinate is discussed. The method can overcome the low accuracy of in- dividual public point coordinates or very large which will give the latge effect on coordinate transformation error the parameters, and calculate the accurate coordinate transformation parameters, so as to achieve the high accuracy of coordinate transformation. Through the analysis of an example shows that this method is practical and effective.
