This intoductory Tutorial shows how you connect your Asus Xtion (R) or Microsoft Kinect (R) with you computer and how you start scanning with FAROs SCENECT software.
Sure thing, from past experience using ReconstructMe and Skanect my guess is that coins might be a challenge, but I will get you some results. Why do you want to scan coins anyway, you going to make some counterfeit money
Specs are slightly better for xtion than kinect. Xtion only has a USB cable because it doesn't have the servo base the kinect does. Xtion pro live has the color option and I am not even sure the other two xtion models are still sold. Doubt it matters which you have for Scenect but I would check the system requirements sheet for scenect. Eventhough one device is a Microsoft product and the other Asus they are both designs of Primesense. Kinect 2 is on the way so you may want to wait on that. One other thing to note about these devices is that they are completely useless outdoors and almost useless in in the dark.
The funny thing is the IR pattern does work in complete darkness, but the most of the software stitches the frames together using features found in the color imagery, which means light must be present. I will see how Scenect fairs tomorrow when I try it out, but it look like it does the same type of stitching. A quick google search said the kinect 2 is most likely set for an early 2013 date, but with Microsoft it could be much later. I will add that my experience with the Xtion using Skanect so far has informed me that using an old dual core laptop is terribly slow compare to using my Corei7 quad at work. From what I can see the more cores the faster each frame is stitched and the faster you can walk around gathering data, but it is hard to walk around with a big desktop under my arm. I would expect that the higher resolution of the kinect 2 will make this process even slower.
If anyone is interested this is what the IR pattern of the Xtion looks like:

No, I already do it right. I'd like to calculate the volume of some etruscan coins to obtain, via the weight and own weight, the percentage of silver in it. Maybe there is an easier, non destructive, way but I want to do it this way combining the documentation with a complete analisys of coins
The depth resolution of both sensors is about 5mm x 5mm due to coded pattern they use. Image resolution in 2D (x/y plane) is much better though. As a result small details get averaged out in depth while the texture is there.
Personally, I am really impressed with the quality of data that one can squeeze out of a 150€ device. It is in any case worth testing it and have some fun with the results!
