This method,which is not only adapted to large rotation angle,but also adapted to small rotation angle,has many characteristics,such as relying less on the initial values of 7 transformational parameters,being able to resist errors from observation values,making the calculates results more accurate,et.
该方法的特点是:不依赖7个坐标转换参数初值,计算收敛速度快,计算结果精确稳定可靠,不仅适合于小旋转角而且也适用于任意的大旋转角。
