摘　　要：在已知不共线3点在两坐标系下坐标的条件下,提出一种快速计算两坐标系间转换参数概略值的方法。通过已知的3点构造出一个新的坐标系,根据该坐标系可计算出待求的两坐标系分别与它的旋转参数,从而求得待求两坐标系间的旋转参数。再根据旋转参数计算出平移参数的概略值。通过实验验证方法的正确性。In this paper,one method was proposed to calculate transformation parameter s approximation of two coordinate systems under the condition of that three points were offered.Firstly,it constructs one new coordinate system with the three points,which is used to calculate the rotation parameters between the new and the two known coordinate systems respectively.We can gain the approximation of rotation parameters between two known coordinate systems.Then we can calculate translation parameters between two known ...
