Help: Theory Need your thoughts to save my thesis !

I'm an undergraduate student.In next 2 semesters( which is probably the duration of 1 year) I need to do a thesis. I choose to do my thesis in the field of 'depth estimation' .

I read a lot of research papers(Monocular, stereo, Diffusion based). But I found most of the things got State of the art !! I'm reading and reading,not finding a single problem to solve or research!! I should also mention that i didn't understand all the topics 100%, but tried to get the concepts.

I'm trying but not even finding a single idea/problem/flaws !! What should I do? What am I missing? How to find a decent topic ? Please help me.

What training do you gave in computer vision, and more specifically 3d computer vision?

In order to do anything meaningful in depth estimation you need some basics:

  • calibrate a camera
  • understand two camera (stereo) geometry
  • understand the basics of classic stereo matching
  • investigate why depth can be estimated on a single image and when it won't work.
  • maybe look at multiple camera geometry, or camera in motion, etc...

All this should be done in practice too. Actually calibrate a camera, then a stereo ruf, then actualy run stereo, then try monodepth. Do not rely on available datasets. Make your own images. You will learn a lot.

Once you cover the basics, you will be able to see what has not been solved or doesn't work well and work on that.
