Photogrammetry generally assumes a fully static scene. If there are static parts of the scene which the camera can see and also rotating parts, the algorithm may struggle to properly match features between images.

i think it's common to have dots on the rotating disk where the object is placed on.

Sure, but if the background has a lot of features it will still confuse the algorithm unless it has some special settings for ignoring the background.
