Is there a way to get a depth stream from ds325 on devices such as Raspberry pi? What if to use Intel Galileo board instead?
If you have a x86 or x64 board, you can use the softkinetic driver and sdk for linux right away.
Raspberry Pi is Arm architecture, can be done if you compile yourself. http://www.hirotakaster.com/weblog/openni2-ds325-driver-for-android-and-arm-linuxraspberry-pi/
