| 摘 要： | 传统的基于泰勒级数展开的线性模型转换方法仅适用于小角度的空间直角坐标转换,角度较大时产生误差较大,需要进行复杂的三角函数和迭代计算,增加了数据处理的难度。而基于Rodrigo矩阵的方法不需要复杂的三角函数计算和迭代计算,且计算速度快,易于程序实现。实验表明,采用Rodrigo矩阵是进行三维坐标转换的一种比较严密简便的方法。

| Abstract: | The traditional method based on Taylor series expansion can be only applied to small angel of rotation,for it will exist great error when the angel reach its limit.In addition,this method require complicated computation of trigonometric function and iteration,which,of course increases the difficulty of data process.While,3-dimension coordinate conversion based on Rodrigo Matrix can work out these problems well.According to the experiment,the application of Rodrigo Matrix is a practical and precise method to be used in 3-dimension coordinate conversion. |
