Is there any standard data format for 3D reconstruction?

When we create a 3D reconstruction, we convert a bitmap picture into some symbolic representation. This description will contain such elements as object names (box, ball, line ...), their numeric attributes (length, height, coordinates ...), symbolic attributes (color ...) ... Is there any widespread format for such representation?

3d reconstruction gives you 3d points (a cloud), that's it.

it does not know anything about objects, structure, or names, all these things would need human annotation.

A shape of the object is needed already now because this object needs to be detected in the image first. Examples which are present in OpenCV handle specifically chessboard. They will not work with a bottle or some book. In the future, it is desirable to have a ready object at the output. It is not difficult if you can recognize it at the input.

Maybe you can use Industry Foundation Classes(IFC) for 3D reconstruction of buildings or indoor spaces

Yes, creating the plan of furniture in a room is one possible task. Can you provide a link?

IFC https://eetd.lbl.gov/sites/all/files/... That what is required. It supports Attribute-driven geometry representation among other things.
