Can multiple identical shots be combined to produce a sharper, higher-detail image?

I’m working with photogrammetry and often struggle with image clarity. Instead of upgrading my camera right away, I’m wondering whether taking several shots of the same scene from a tripod and combining them could improve the final result.

I’m not asking about focus stacking or making a panorama from different views. I mean using multiple near-identical images to refine a single image and recover more detail or sharpness, while keeping lens characteristics consistent for photogrammetry.

Is there an established technique for this?

Absolutely. This is called "superresolution", and we actually have a number of questions and answers on it in the superresolution tag. There is also a wikipedia article where you can learn more.

Yes. The established technique is generally called superresolution (or super-resolution).

It combines multiple images of the same subject to estimate a higher-detail result than a single frame can provide. This is different from focus stacking and different from stitching a panorama. In principle, it can improve apparent detail when the images are aligned well and contain slightly different sampled information.

For your use case, the key points are:

  • the shots must be very closely aligned
  • consistency in lens/camera setup matters
  • results depend on image quality and the software/method used

So the short answer is: yes, combining several nearly identical photos into one finer result is a real, established approach, and the term to look up is superresolution.
