摘要
为了加快工程测量中大角度三维坐标转换的速度与精度,基于罗德里格矩阵,进行进一步推导与简化,提出了一种线性的三维坐标转换方法。与传统的三维坐标转换方法相比,具有运算速度快、无须进行初始值估算等优点,非常便于在工程测量中应用;而且通过与其他方法进行精度比较,可以看出本文所提出的方法在一般情况下精度优于传统方法。同时,此方法也存在部分参数几何意义不明显的缺点,无法用于理论研究工作。最后,使用一个工程测量中应用的实例,对比论证了所提出方法的可行性与优缺点。
In order to speed up the speed and accuracy of large-angle three-dimensional coordinate transformation in engineering measurement,this paper proposes a linear three-dimensional coordinate transformation method which is based on Rodrigues matrix.Compared with the traditional three-dimensional coordinate transformation method,this method has the advantages of high calculation speed,no need to estimate the initial value,furthermore,is very convenient for application in engineering measurement.Moreover,by comparing with other methods,it can be seen that the method is superior to the traditional method in general.Of course,this method also has the disadvantage that the geometric meaning of some parameters is not obvious and cannot be used in theoretical research work.Finally,this paper gives an example of the application of this method in engineering measurement.
