This is far too expensive for what it offers. Within a couple years, we'll have 3D scanning "wands" that we can wave all around an object to get a full 3D model. You can already do this with a kinect - though it's not all that elegant. Using the same technology with better cameras and sensors, plus some accelerometers for positional reference, should not be all that difficult. For a grand, that is the sort of functionality they should be providing right now. Limiting the device to still "images" and requiring a calibration placard are inexcusable limitations at this price point.
By the time we see an iphone 8 or 9, expect that sort of thing to be built-in. In the not too distant future, expect vector-based video to be the norm.
