摘要
根据二次曲面转换GPS高程,求取转换参数所列的方程,方程系数矩阵由已知点的坐标组成,提出利用归一化的方法优化坐标系数矩阵,求取坐标参数。其计算结果和精度优于利用坐标中心化、平均法进行处理的方法。
According to quadric surface method of conversion GPS height,the equation listed out by conversion parameters is obtained.The equation coefficient matrix is composed by the coordinate of given point.Using the method of normalized to improve the coordinate coefficient matrix,and to obtain coordinate parameters.The calculation results and is better than the of coordinate centralization method and average method.
