Getting Raspberry Pi, OpenNI2, and Asus Xtion Pro Live To Work Together

UPDATE Feb 28, 2013:

– It works on my 256MB Raspberry Pi with Asus Xtion Pro Live tested through powered USB Hub from Belkin.
– Camera viewer that is shipped with OpenNI (NiViewer or SimpleViewer) will not work because it’s built with OpenGL. Raspberry Pi doesn’t support OpenGL. So to get camera visualization we have to use OpenCV. In the source above he uses OpenCV from raspbian repository. But since I’m gonna do image processing with OpenCV so I prefer to install it manually.
– Building OpenNI2 from source will take a lot of time. To save the fuss you can grab the pre-compiled Raspberry Pi package from Hirotaka’s website above (OpenNI version 2.0.0), or my package (version 2.1.0, size ca. 1.5MB) here.

For OpenNI2 installation, first install the dependencies:

sudo apt-get install git g++ python libusb-1.0-0-dev freeglut3-dev doxygen graphviz

Please note that doxygen and graphviz needs 600-ish MB to download (5 minutes at ca. 2 MByte/s), and they will take around 900MB of your SD Card space once installed. They are needed to compile the documentation. Once OpenNI2 is built, we do not need this two packages anymore (I think). So if you have limited internet speed, this step itself will take a lot of time, not to mention Raspberry Pi is very slow when it comes to package installation. As mentioned before, you can just download the pre-compiled package and it will work just fine.

Now grab a copy of OpenNI2 source code from github:

git clone

Then there are two files that needed to be altered:
First OpenNI2/ThirdParty/PSCommon/BuildSystem/Platform.Arm. Change or comment this line:

CFLAGS += -march=armv7-a -mtune=cortex-a8 -mfpu=neon -mfloat-abi=softfp #-mcpu=cortex-a8

then replace or add with this:

CFLAGS += -mtune=arm1176jzf-s -mfpu=vfp -mfloat-abi=hard

The second file is OpenNI2/Redist/ Go to line 534 to find this:

compilation_cmd = "make -j" + calc_jobs_number() + " CFG=" + configuration + " PLATFORM=" + platform + " > " + outfile + " 2>&1"

Then duplicate the line, comment the original and change the copied line:

#compilation_cmd = "make -j" + calc_jobs_number() + " CFG=" + configuration + " PLATFORM=" + platform + " > " + outfile + " 2>&1"
compilation_cmd = "make -j1" + " CFG=" + configuration + " PLATFORM=" + platform + " > " + outfile + " 2>&1"

Now let’s build OpenNI2:

cd OpenNI2/

This took ca. 30-40 minutes on my Raspberry Pi.

Then create the OpenNI2 package:

cd Redist/
./ arm

Now you can find the installer package (OpenNI-Linux-Arm-2.1.0.tar.bz2) in the folder OpenNI2/Redist/Final.

To install this package, simply unzip it to somewhere. I chose in /usr/local/src. You might need to change your group into staff so you have write permission in that folder. I’m not sure whether this is “safe” or not.

sudo usermod -a -G staff pi

Or just use sudo while copying.

cd Final/
cp OpenNI-Linux-Arm-2.1.0.tar.bz2 /usr/local/src
cd /usr/local/src/
tar -xjvf OpenNI-Linux-Arm-2.1.0.tar.bz2

Now that we have the installation package, let’s install it:

cd OpenNI-2.1.0-arm/
sudo ./

Nothing will come up if you got it right. Now you can try if it works with your Asus Xtion. First make sure it’s detected in your Raspberry Pi, check the output of lsusb -vv, it should come up somehow like this:

Bus 001 Device 006: ID 1d27:0600  
Device Descriptor:
  bLength                18
  bDescriptorType         1

  iProduct                1 PrimeSense Device
  iSerial                 0 

### DELETED ###

Device Qualifier (for other device speed):
  bLength                10
  bDescriptorType         6
  bcdUSB               2.00
  bDeviceClass            0 (Defined at Interface level)
  bDeviceSubClass         0 
  bDeviceProtocol         0 
  bMaxPacketSize0        64
  bNumConfigurations      1
Device Status:     0x0000
  (Bus Powered)

If it’s giving

Bus 001 Device 006: ID 1d27:0600  
Couldn't open device, some information will be missing

unplug and plug in other USB port. My 256MB Raspberry Pi is able to detect the sensor without powered USB hub, but it couldn’t get any data out of it. Some say this is because this RPi version has lower USB bandwidth. But in Hirotaka’s website he’s connecting Xtion directly to his 512MB Raspberry Pi and it works just fine.

Then try to read the sensor data:

cd Samples/Bin

This is my output:

ariandy@raspberrypi /usr/local/src/OpenNI-2.1.0-arm/Samples/Bin $ ./SimpleRead 
Warning: USB events thread - failed to set priority. This might cause loss of data...
[00000000]     3816
[00033369]     3816
[00066738]     3816
[00100107]     3816
[00133477]     3816
[00166846]     3816
[00200215]     3816
[00233584]     3816
[00266954]     3816
[00300323]     3816

If you get the same output, you should get something nice for yourself and celebrate!

Now we just have to make an OpenCV viewer program, because the default SimpleViewer will not compile on Raspberry Pi.
