I wonder how the photogrammetry aspect will intersect with intellectual property laws. The example used - scanning in a Santa Monica bar so that you can do reshoots without revisiting the location - would be an obvious example that might raise someone's hackles ("because it's our bar you're using to make your money" for instance). If you add that bar to your digital library, do you have to pay them royalties each time you use it? Is it any different to constructing a practical replica of a real-life location?

Can someone wearing a few cameras walk through a building and digitise it completely without getting the owner's permission? Here in Australia, "copyright in a building or a model of a building is not infringed by the making of a painting, drawing, engraving or photograph of the building or model or by the inclusion of the building or model in a cinematograph film or in a television broadcast," for instance. (Copyright Act 1968 §66)
