摘　　要：提出一种分步求解三维坐标转换过程中的三类转换参数的方法,其中最为复杂的旋转参数选择基于罗德里格矩阵的坐标转换模型,适用于大旋转角,解算过程清晰、计算简便、可靠性好。This paper puts forward a stepwise solution method for three-dimensional coordinate transformation parameters that can suit any rotation angles. The transformation model based on Lodrigues matrix is chosen to solve rotation parameters, which is the most complicated part in the process of coordinate transformation. The method presented in this paper is feasible, easy to understand and suitable for solving by computer.
