This is called photogrametry for those that are interested. Nothing new really. You can already do this in all the major 3d apps although it's a pain compared to apps made to do properly. Just load up a 3/4 view picture as an image plane match your grid and fov to the distortion of the pic, use the ground as reference. Then model some shit. I guess the fancy part is how it animates your camera based on the video. Two times I know of this technique being used is in the matrix part 1 the rooftop bullet dodge scene, all the environment surrounding neo is modeled and textured this way. And fight night round 3 the warehouse and other environments were modeled and textured this way.
