I would like to get better orthographic images for FreeCAD modeling. I mean take pictures from several angles to create an orthographic view of the object. Nothing comes up in F-Droid for photogrammetry. My cynical side imagines this is likely a similar bottomless rabbit hole like modeling turbulent flow or finite element analysis; where empirical brute force and iterating physical prototypes is far more time efficient than the tools freely available. I would love to read any comments if any of y’all know of ways to do this practically or especially efficiently.
I’ve been looking into this as well! I found Meshroom the other day which looks good, going to set it up myself here soon
It might help as a reference? You just get a mess of triangles, I doubt that’s what you’re looking for if you’re using FreeCAD. It sort of works to make 3D printing models, the problem is the resulting mesh is a headache to edit directly. You can use tools to automatically clean it up somewhat, and make it manifold so it will print.
You should watch some videos on photogrammetry to see what it does, and what it doesn’t, to know if it would be helpful for your application. https://www.youtube.com/watch?v=2TXdlUZJyIQ
I’ve used meshroom, it works. I used it to make a 3D reference model from a video to calculate the volume of a hole.
It is only something I want to use when complex curves have no reference origin.
