Subject: Re: [MCG] Kinect / windows
Hi Danny,
I've done quite a lot of work with the Kinect (from a robotics standpoint). I can say immediately that it is going to depend on if you are using the Kinect 1 or the Kinect 2.
For the K1 I can immediately see a problem in that the K1 doesn't see through a lot of glass. The visual camera part will sure but the 3d detection part of the K1 works by projecting an infra red pattern onto the things it is trying see and then viewing the pattern with an IR camera. Glass can block IR so trying to look through your window may be a non-starter.
The other issue is that the IR pattern is totally overwhelmed if the objects are in direct sunlight. The IR from the sun just obliterates the IR pattern from the kinect.
The K2 on the other hand works by time of flight, measuring how long light takes to go from the kinect to the object and back again. Less picky on glass and less picky on sunlight (although not totally immune).
Unfortunately the K2 is much more expensive (can get a K1 for £25 2nd
hand) and Microsoft have been jerks and, after saying that they wouldn't, gone and locked down which systems the K2 will work with (Windows 8 and 10 only whereas the K1 will even work on a Raspberry Pi 2).
Hope that helps.
David
