基于非线性同伦思想 ,提出了非线性同伦最小二乘平差统一模型 ,该方法既可适用于满秩网非线性最小二乘平差 ,也可适用于秩亏网非线性最小二乘平差。算例表明 ,对于精度较差的初始值 。
On the basis of the homotopy arithmetic, this paper puts forward a uniform model of nonlinear least square (LS) adjustment, which can be used not only for the nonlinear LS adjustment of the rank defect problems, but also for that of the rank full problems. For the initial value with later precision, it is shown by the actual nonlinear function examples that we can still get the precise original solutions by homotopy nonlinear LS method.
