【Abstract】 A simple and convenient model of coordinate transformation which can be used for any rotation angle is proposed in this paper.First,the coordinates of each point in both coordinate systems are centralized to their barycenters.Then,the transformation matrix can be calculated by these centralized coordinates.The proposed method is used in two cases,a simulated example and an engineering project.Meanwhile,the transformation results are analyzed and compared for the purpose to indicate the method application process and effectiveness. When it is used in attitude control of subway tunnel shield,satisfied results can be obtained.更多还原
