Abstract
Two new methods for homotopy nonlinear robust estimation method and homotopy restricted-nonlinear method are proposed.Moreover,the corresponding nonlinear functional models for the two methods have also been deduced accurately.Numerical experiment results show that the methods developed have low requirement for the initial value,with fast convergence speed and better precision,which is an effective method in the nonlinear surveying model parameter estimation.
