中文摘要：
基于整体最小二乘方法推导求取坐标转换参数的公式,使用参数变换方法求解参数估计公式的非线性问题,避免了常规的矩阵分解方法计算的复杂性。另外,为了适应不同地区使用不同的转换模型,还推导了仿射变换模型的参数估计公式。
英文摘要：
On the basis of the mathematical meaning of the overall least-squares,through transformating conditional extremum to direct extremum,the formulas of solving transformation parameters by overall least-squares regression are derived and the nonlinear problem in parameters estimation is solved with the parameter transformation method to avoid the issue of linearization.The feasibility of this new algorithm is verified by measurement data and the problem of theory defect in traditional method was solved.Futher more in order to meet the different conversion models used in different regions,the parameter estimation formula for affine transformation mode is derived.
