How do I align assembly-progress photos in Hugin when Align Image Stack reports “No Feature Points” and “Bad Params”?

I’m trying to align several photos showing different stages of assembling an electronic circuit. In Hugin on Windows 10 (2019.2.0), I used the Align image stack workflow, chose geometric optimization positions (y, p, r) and the default photometric option low dynamic range, then clicked Create control points. It fails with align_image_stack.exe failed with error code: 1. From the command line, align_image_stack reports “No Feature Points” and “Bad Params.”
Are these the wrong settings for this kind of subject, and what’s the correct way to align these images in Hugin?

Do not use an image stack (this is meant for images with the same content but different exposures). Instead just do a regular alignment, I just tried with your 3 example images (on a Mac), this works fine.

Yes — the issue is likely the workflow, not your command syntax. In Hugin, Align image stack is intended for images of the same scene/content, typically for exposure blending or focus stacking where the subject does not change between frames.
Your photos show different assembly stages, so the content changes from image to image. That can prevent align_image_stack from finding enough matching feature points, which leads to errors like “No Feature Points” and “Bad Params.”
Use regular alignment in Hugin instead of the image-stack workflow. A normal panorama-style alignment/control-point generation is the appropriate tool here, and according to the community test, your three sample images align successfully that way.
So the fix is:
- Do not use Align image stack for these images.
- Load the images normally in Hugin.
- Run the standard alignment/control-point creation process.
- Then optimize and align as a regular project.
If alignment still struggles, ensure the images have enough overlapping visible details and consistent framing, but for your examples the standard alignment should work.
