摘　　要：本文简要介绍了空间直角坐标转换的七参数模型和布尔莎模型,针对线性布尔莎模型不适用于大旋转角度空间直角坐标转化的问题,阐述了一种非线性布尔莎模型,并详细推导了参数解算过程,仿真模拟实验结果表明:非线性布尔莎模型具有较高的参数解算精度和稳定性,且适用于任意旋转角度的空间直角坐标转换。In view of the problem that the linear Bursa model is not suitable for the spacial rectangular coordinate transfor- mation when the rotation angle is large, the paper presents a nonlinear Bursa model and derives the parameter calculation process in detail. The simulation results show that the nonlinear Bursa model has higher parameter calculation accuracy and is suitable for the space coordinate transformation in any rotation angles.
