摘 要: 基于大角度的空间直角坐标转换 ,提出了以方向余弦为参数、适用于任何角度旋转的空间直角坐标转换的简明计算方法。 Three dimensional datum transformation is widely used in geodesy, photogrammetry, engineering survey and other subjects. The Bursa model,molodensky model etc. are usually used. General speaking, they are mainly suitable in small angle's three dimensional datum transformation. But in actual, a lot of large angles' three dimensional datum transformation need to be performed. This paper puts forward a simplified model of three dimensional datum transformation that can suit any angle.
