Radiography - 3D imaging

[JakubZaruba]

Hi all!

As part of my bachelor's degree, I would like to improve radiographic imaging with 3D modeling.
At the workplace where I work, we process radioactive waste, and radiographic equipment is used to reveal the internal structure of the barrel.
Now I'm looking for a way to make a 3D model from radiographic images of sections.

Do you think Metashape would be used for such a purpose?
I tried the free version, but no matter what I test, it still doesn't work.

I am attaching three images as a demonstration. Of course, there can be any number of angles. Under normal circumstances it can be seen better. I'm currently using a weaker source that doesn't shine through the barrel as well.

Thank you for any advice! :-)

Hi JakubZaruba,

I don't think that you'll have success with Metashape or any other photogrammetry package, because normal photogrammetry works with the laws of reflection and central perspective only and not with translucent materials.

Probably you'll have more success with mathematics and software used in computer tomography.


Best regards,

Kiesel

This reminds me an old thread about X-ray scanning:

Alexey,

Ah yes that was a funny one by Mark Florquin!

Very good,

still there is whole branch of photogrammetry using Xray images radiogrammetry. I had a colleague at University who did his Phd on finding best path (avoiding blood vessels)  to introduce a probe in a skull using a pair of X rays and floating line principle  .. Michel Boulianne... Used a lot by surgeons before operating see https://www.isprs.org/proceedings/XXVI/part5/145_XXVI-part5.pdf and https://www.isprs.org/proceedings/xxv/congress/part5/335_XXV-part5.pdf

I have found this.

Looks like it was done with the former Photoscan in 2015.

There is that open source project too:

Thank you! :-)
