【摘要】 三维分离回归法是一种简单、有效、实用的转换方法,该方法可有效地克服病态矩阵问题。同时,为切实、有效地提高三维分离回归法的转换精度,计算时引入了三向尺度因子,使得三维转换参数由传统的7个变为现在的9个。详细介绍了三维分离回归法的基本原理、转换过程及转换实例。更多还原

【Abstract】 The morbid matrix will arise in using traditional method to transform the three-dimensional GPS coordinate into national coordinate in GPS survey.The author provides a simple and effective coordinate transformation method.This method is three-dimensional separate regression method.This method can avoid the morbid matrix occurrence.In this paper,the basic principle and transformation process and transformation example of the three-dimensional separate regression method are introduced.更多还原
