Abstract: The paper considers the problem of estimating a transformation connecting two images of one plane object. The method is proposed for calculating the parameters of projective transformation by data consisting of points and lines. The results of the experiments on synthetic data are presented, in which the rate of the algorithm convergence was studied depending on the ratio of primitives in the original dataset. Also the advantage of using directly straight lines, rather than points of their intersection is experimentally shown.

Keywords: projective transformation, RANSAC.
