| 摘 要： | ECEF坐标到本地坐标转换公式是数据融合中常用的公式。但是在实际工程应用中,发现参考文献列举的论文中所提供的公式存在不同程度的错误,而正确的公式又没有给出推导过程。为了避免进一步的错误使用,文中从坐标的几何图形出发,推导了两个坐标系的坐标相互转换的系数矩阵,其形式与正确的结论相同。然后通过对典型坐标进行计算并验证,结果表明该公式是正确的。

| Abstract: | Formula to convert ECEF coordination to local coordination is frequently used in data fusion application.Through engineering experience,formulas provided by papers listed in reference documents are proven error-existing here and there,but the right formula can not be confirmed by precise proof.To avoid farther promiscuous usage,the linear transformation coefficient matrix for coordination conversion is got based on the geometry view of coordination system.Through farther calculation and verification of typi... |
