I am new to CV (or, actually not even started yet), so assume no specific knowledge on my side…
I want to read waterlevels from pictures like these here:
(remove the filename part if the page is broken).
Ideally, i would want a cm reading. For this, it would be probably simplest to read a strain-gauge mounted or painted against a big rock.
But this is not feasable in many places like the above shown.
So, even if i can’t get a cm-reading from the image, any kind of number would be better than the raw image. Smoething that can be used to plot a (possibly not very accurate) graph.
The camera could also supply short video clips, if it would make detecting water-movement easyer.
In general, i wonder what experienced people think about the difficulty, best approach and possibly prior work.
I imagine the moving water (or generally water) vs. land could be detected and the ratio would be a number that i could use.
But as i have almost no knowledge about CV, there might be totally differnt approaches to this.
Also, i have read that IR images could help in detecting water vs. land. But looking at the ir-images, i don’t see immediately how this would help.
So, i hope to get some tips from people here. Or, maybe someone is even interested in the challenge and wants to contribute more? You would be more than welcome to contribute.
