Approach to metric reconstruction based on trifocal tensor

This paper proposes an algorithm for trifocal tensor,the method makes use of a set of image point correspondences from three images which taken by RANSAC method accomplish the estimation of the trifocal tensor,which computes briefly and completes easily in the range of the errors.

In order to avoid miscorrespondences on three uncalibrated images matching,the trifocal tensor is used in correspondence of tree trunks,and tree trunks lines could be fixed by lines transfer of the trifocal tensor.

To avoid the complex computation of trifocal tensor,a simple strategy is presented.
