| Abstract: | The centroid of the visible light CCD image targets can be derived by using lots of methods,these algorithms are also suitable for the near infrared stellar map.The common methods are: Gauss fitting method,method of moments,derivative search and so on.The Gauss fitting method is introduced and analyzed its advantages and disadvantages.According to this method,a more practical method is proposed based on the near infrared stellar map navigation,verified and compared its accuracy and feasibility. |
