摘　　要：给出了七参数三维直角坐标转换的严密表达式,将改进SQPM算法用于大旋转角的三维直角坐标转换。实验表明该方法能在大范围内实现收敛且结果稳定、精度较高,适合于大旋转角的三维直角坐标转换。The rigorous formula of 3D rectangular coordinate transformation with 7 parameters are presented. The improved SQPM algorithm is used for 3D rectangular coordinate transformation with big rotation angles. The results show that the algorithm is stable in result, great in accuracy and wide in convergence which can adapt to big angle of 3D rectangular coordinate transformation.
