i want to reconstruct 3d image from two 2d images. In the process i wanted to find intrinsic parameters using kruppa equations. please help me to obtain intrinsic parameters.

The paper is actually giving you the answer. You estimate the dual of the absolute conic image K=AAt with A being the intrinsic matrix.

K estimation is done my minimizing eq. 33 and you extract A from K-1 with a Cholesky decomposition (page 7, before section7).
