摘要
本文针对我国平面控制网与高程网分开布设的特点，借助于与站心坐标系指向一致的过渡坐标系，改进了计算坐标转换参数的常用模型。改进后的模型联合平面控制点的坐标和高程控制点的高程求解与其他３维空间坐标的７个转换参数，不需要３维已知点。并用算例说明了本文所提出的模型的优越性。
According to the plane control net and the height control net are established seperately in our country, this paper improves the common model of calculating the transform parameters by use of interim coordinate system which has the same orietation with topocentric cartesian coordinate system. The improved model can combined the plane coordinates of plane net and the height of height net to calculate seven transformation parameters with other three dimensional coordinate system. The advantage of the model pointed out in this paper is shown with a sample.
