Has anyone ever tried to use photogrammetry to reconstruct 3D georeferenced shapes in matlab?

Hi,

I'm very interested in photogrammetry and would like to see if there could be bits of scripts or some knowledge on the topic out here. I would like to understand if and how matlab has or could be used to analyse overlapping images to reconstruct 3D shapes and orthomosaics, for educational purposes mainly. I contacted these guys https://www.youtube.com/watch?v=fw44OM8ovfA but they are playing hard to get and I wonder if this is not a scam.

So has anyone ever written a piece of script that could do that on matlab?

Thanks,

I made this repository for a university project. Hope it helps.

Hello ,

As per my understanding you want to resconstruct 3D image from set of 2D images but unfortunately MATLAB currently does not have a built-in function to achieve this. However, you may be able to find implementations of this functionality by MATLAB users on the web. For example, the following link points to a MATLAB File Exchange submission on reconstructing a 3D image:

https://www.mathworks.com/matlabcentral/fileexchange/8772-surface2volume

Please note that any questions about the above File Exchange submission should be directed to the author of the submission.

There does not seem to be that much on the topic in matlab you are right. Thanks for your answer!
