      Seeing post about image stitching for IC's, has me thinking about an automated image stitching rig. Use lasers at points across the face to evaulate surface shape and create a more seemless automated stitch. Thoughts on how this would work?

      I get the feeling this is a problem we can solve with (better) code. Planar stitching isn't very hard. Might want a calibration target to determine the lens distortion parameters first and then it should be easy.

      Agree that lens calibration is a thing. Also determine angle of camera to stage axes. I ignore lens calibration by cropping the borders (so pincushion isn't so bad) and just search for a reasonable perspective transform for the camera angle.

      I think a lot of this could be solved by writing a better control point auto finder for Hugin. Hugin knows how to optimize lens parameters, but its default auto finder does a poor job on ICs.
