What are the algorithms for restoring 3D objects from multiple images?

I have several photos of the building from different but close angles. I have highlighted special points with descriptors on the images. Tell me the names of algorithms or articles that can be used to restore the spatial distribution of singular points in several pictures. Is there anything for this in OpenCV?

There is an open source OpenMVG project that implements this. You can take from there some stages of restoring geometry from a photo and use it as a plug-in library. OpenMVS
can be used to further restore the entire surface of the object .

no, at best, neurons on known objects

There are such methods. The topic is called "restoring a 3D object model from a stereopair"
