Hole in panorama

[Robert Simpson]

I'm attempting to stitch some scans of a schematic. The scans are quite poor quality and have some distortions. I have no idea what was used to make them.

I manually added control points and stitched them but the resulting image has a chunk missing. See attached images. Any ideas on how to fix it?

Thanks,

Rob.

Others might explain the best Hugin procedure to stitch these and also explain why you have that void but you are missing a sliver between the 2nd and 3rd images. That missing sliver contains how the feedback circuit, if any, is accomplished at the op amp that is partially shown in the 3rd image. It looks like you need another image to fill in that missing information.

I think it's either a stitching problem or you've inadvertently masked out that section of the image. Switch from enlblend to built-in or vice versa, or check the Masks tab.

I think that's a comparator rather than an op-amp. Yes, there is a missing sliver but I think it's very thin. I had to manally add the control points. I don't understand how any of this results in a chunk of the original images being removed.

I don't have any masks set. I tried Enblend but no difference.
