This paper proposed a nonlinear method to esti-mate it based on Errors-in-Variables (EV) model. After setting up the EV model,this paper adopted nonlinear object function,and estimated both parameters in the model and measurement errors. Besides,this method also considered normalized coordinates and the rank 2 constraint of the fundamental matrix. Experiments of stimulated data and real images show that this method significantly in-creases the accuracy of estimation.
