Could ODM work for (multiple) fixed position cameras too?

#1

Hi,

We use fixed position cameras (like CCTV cameras) to capture video of construction sites. On some sites, we have cameras from 4 or 5 angles.

Could ODM be used in this case? To generate 3d models with only 4 or 5 camera angles?

With my limited experience in making 3D models (Agisoft Metashape, Pix4D) you need a significant amount of image overlap (80+ percent overlap) in order to make a good 3D model. I don’t think 4 or 5 cameras will generate enough overlap to make this work.

That said, I’m curious to know what others would say as well.

It cannot work well, unfortunately. Photogrammetry needs camera motion to estimate the camera parameters (good overlap also is important).

With that said, try it and discover by experimentation.

With more cameras, this could certainly work, but is likely to be difficult with ODM with only 4 or 5 cameras.
