Line detection - using hough transform 2

Ok, so it didn't work that well, but it seems like it is working now, also with real points.

The subproblem of disallowing the same peak in the hough-space to create multiple lines was solved by maskin out the area such that we are sure there is some minimum distance betwen the lines ( that is distancebetween the a and b parameters )

The two images shows, first the laser line on a dark image, and second the lines detected on a thresholded image.
