Abstract

The data fitting model is the basis for data processing in the positioning of digital zenith camera. In this paper, the similarity transformation model, affine transformation model, projective transformation model and the solution of parameters of these models were strictly deduced. And the three data fitting models were applied to the positioning algorithm of the digital zenith camera. Experimental results showed:When the similarity transformation model and the affine transformation model were used for positioning, the positioning accuracy of the digital zenith camera was basically the same. When the projection transformation model were used for positioning, the accuracy of the data fitting and the positioning accuracy of the digital zenith instrument were better than those of the other two data fitting models.
