Essential Matrix computation with Ransac 3000 iterations

edit

The following function generally provides inaccurate Essential Matrix.

E, mask] = cv.findEssentialMat(ptsObj,ptsScene,'CameraMatrix',K,'Method','Ransac','Threshold',1);

Is there any way to compute the Essential Matrix using the above function with Ransac's 3000+ trials? Can we use loops in any way to accomplish a robust and more accurate solution?
