That is very impressive. I used to do a lot of photorealistic modelling using mental ray or vray in 3ds max, andt he level of precision of this is quite frankly extraordinary. This could very be a game changer in the 3D industry.
Camera matching usually requires a lot of forethought and preparation of the physical scene, involving thoroughly surveying the location & obtaining light-probe data so that an accurate 3d model of the scene can be produced and the inserted objects lit correctly.
This could make composing 3d/practical images a trivial exercise, very nice.
