摘要
不同坐标系统的相似变换法一般不足以将两坐标系统间的差异纳入坐标转换模型 ,因而低精度的坐标框架到高精度的坐标转换往往不能保证统一后的坐标框架的高精度。本文试图将相似变换与回归逼近相结合 ,以便顾及低精度大地网中的局部误差积累和变形 。
The similarity transformation method between different coordinate systems is not enough to describe the discrepancy of them. So the coordinate transformation from low precise coordinate frame to the high can not make sure a high precise reference frame after this transformation. In this paper, a combined method of similarity transformation and regressive approximating is presented. The local error accumulation and distortion are considered using the combined method and the precise of coordinate system is improved after the transformation using the recommended method.
