OpenNI/NITE CPU usage

[Hans Gaiser]

Hello everyone,

I've been working on getting the Kinect working on my Pandaboard (1.2Ghz dual core ARM), but it doesn't seem to have enough processing power to read out the Kinect at 30fps.

Now I was wondering about the CPU usage of OpenNI / NITE. On my laptop, which can run both Windows and Ubuntu, I tried the same Kinect application (the kinect_maps.cpp example in OpenCV, run with parameters so only the RGB images are shown) on both operating systems. On Windows it took approx. 10-20% of my CPU, while on Ubuntu it took approx. 40% of my CPU. From the same hardware I'd expect similar CPU usage on both OS's.

Is there something that can be done to improve the efficiency on Ubuntu and thus on my Pandaboard (which also runs Ubuntu)?

Thanks in advance.

Hello Hans

I would like have some questions to you.

We are trying to build some application using kinect and ubuntu and we are trying to connect output to a HD TV from panda board directly.

Will it have enough processing power to have the gesture based control for controlling some simple apps in the TV?
