Re: [hugin-ptx] Combining small X-rays of circuit boards to make one complete image
I already used Hugo for stitching >200 screenshots from the microscope to a big picture one can do deeper analysis on. The only place hugin needed help was when it placed a few control points into the wrong repetition of a repetitive structure. -- A list of frequently asked questions is available at: http://wiki.panotools.org/Hugin_FAQ --- You received this message because you are subscribed to the Google Groups "hugin and other free panoramic software" group.

Re: [hugin-ptx] Combining small X-rays of circuit boards to make one complete image
Hi James, Depending on the distance between object and x-ray source there will be some amount of parallax. It might be a good idea to put all control points on the actual pcb (preferably even the same side of the pcb) and not the components. Apart from that, as Bruno is saying, this is well within scope and 45 is not a very large number. cheers, lukas wirz On 21/12/2023 17:11, James C.

If so, I might be able to help. The second obstacle is that the x-ray image files have no EXIF data, so control points must be hand selected for every image. The third obstacle is that my circuit board is approximately 3" x 17", and the x-ray captures an area 1 1/4" x 7/8", so the whole thing takes about 45 images, (three rows of 15) allowing for overlap. I had to stitch segments made up of no more than 5 images at a time, hand-generating control points and using Advanced - Fast Panorama Preview for Move/Drag, Straighten to remove distortion. The fourth and current obstacle has to do with stitching together my stitched segments. The workflow is horizontally oriented, thus prompting my first question: 1) Does the tutorial give any relevant details on stitching vertically? Another current issue is that I tried stitching the first two segments, and my first segment image appears in the field about 1/3 the size of the 2nd segment. They are the same length, but different heights. 2) Why is one image appearing smaller than the other? The main concern is that this job may be too big for Hugin. I have spent a lot of time on this and need it to work. If it does, I need to fine-tune my work-flow to be able to do the same on other circuit boards. If I need to be using something else, please let me know (gently!). Any help towards these obstacles would be very much appreciated. -- A list of frequently asked questions is available at: http://wiki.panotools.org/Hugin_FAQ --- You received this message because you are subscribed to the Google Groups "hugin and other free panoramic software" group.

If you have preliminary alignment of your images, this seems better suited for the task than Hugin.

Re: [hugin-ptx] Combining small X-rays of circuit boards to make one complete image
Hi James, a multi-row stitch with 45 images shouldn't be a problem, this isn't a big project relatively. It isn't a 'normal' panorama where the camera has a fixed position and the photos only vary by rotation. Probably the rotation doesn't vary and the only thing that varies is the camera position - this is much more similar to joining scans or microscope slides, or assembling a mosaic of a wall/mural, all of which can be done in Hugin. Do you have any sample images? With an example it will be easier to say what approach needs to be taken. -- Bruno On Thu, 21 Dec 2023, 15:17 James C.

[hugin-ptx] Combining small X-rays of circuit boards to make one complete image
My current project is learning to use Hugin to create complete pictures of circuit boards from x-rays to be used for troubleshooting/repairs. I have obstacles. The first obstacle has to do with the fact that I have the latest version of Hugin for Windows, but the tutorials are over 10 years old. Is anybody working to update the tutorials? If so, I might be able to help. The second obstacle is that the x-ray image files have no EXIF data, so control points must be hand selected for every image.
