摘要
介绍了采用罗德里格矩阵进行三维坐标转换的方法,提出了一种非常简单的坐标转换参数初值求解公式。推导得到了进行坐标转换平差的间接误差方程,并通过算例验证了该方法的可行性和正确性,为三维坐标转换提供了一种简单方便、易于编程实现的方法。
In this paper,we introduced the 3D coordinate transformation method based on Rodrigues matrix,and put forward a very simple formula for solving initial value of coordinate transformation parameter.And then,we deduced the indirect error equation of coordinate transformation adjustment in detail,and verified the feasibility and correctness of the method by an example.This study can provide a simple,convenient and easy programming method for 3D coordinate transformation.
