| Abstract: | The principle of semi-parametric regression was introduced and the application of the Semi-Parametric model in the field of surveying data processing was analyzed and discussed.According to a simulating test,the semiparametric regression model can better separate systematic errors from observations compared with the LS model,which shows that semi-parametric regression analysis has a good prospect in modern measurement. |

| Keywords: | semi-parametric model penalized least squares technique LS estimator systematic error |
