摘　　要：笔者针对大旋转角三维直角坐标转换中两类坐标均存在误差的情形,首次联合加权整体最小二乘及改进SQPM算法用于解决该问题,结果表明,本方法结果稳定、精度较高,适合两类坐标均存在误差的大旋转角三维直角坐标转换。The author of the case of large rotation angle three-dimensional Cartesian coordinate conversion in the two types of coordinates errors,the first joint Weighted Total Least Squares and improves SQPM algorithm used to solve the problem.The results show that the results are stable,high accuracy,suitable for two types of coordinate errors rotation angle three-dimensional Cartesian coordinate conversion.
