libfreenect

libfreenect is a userspace driver for the Microsoft Kinect. It runs on Linux, OSX, and Windows and supports

  • RGB and Depth Images
  • Motors
  • Accelerometer
  • LED
  • Audio

Notice: If you have the newer Kinect v2 (XBox One), use OpenKinect/libfreenect2 instead.

Build Instructions

To build libfreenect, you'll need

  • libusb >= 1.0.18 (Windows needs >= 1.0.22)
  • CMake >= 3.8.2
  • python >= 2.7 or >= 3.3 (only if BUILD_PYTHON=ON or BUILD_PYTHON2=ON or BUILD_PYTHON3=ON or BUILD_REDIST_PACKAGE=OFF)

For the examples, you'll need

  • OpenGL (included with OSX)
  • glut (included with OSX)
  • pthreads-win32 (Windows)

Fetch & Build

git clone https://github.com/OpenKinect/libfreenect
cd libfreenect
mkdir build
cd build
cmake -L .. # -L lists all the project options
make

# if you don't have `make` or don't want color output
# cmake --build .

Use CMake options to control what gets built. For example, to build the Python wrapper (defaults to system Python):

cmake .. -DBUILD_PYTHON=ON
make

Or the Python 3 wrapper:

cmake .. -DBUILD_PYTHON3=ON
make

You can specify a build with debug symbols:

cmake .. -DCMAKE_BUILD_TYPE=debug
# or with optimizations
# cmake .. -DCMAKE_BUILD_TYPE=RelWithDebInfo

You can build .deb, .rpm, and/or .tgz packages with cpack:

cmake .. -DBUILD_CPACK_DEB=ON -DBUILD_CPACK_RPM=ON -DBUILD_CPACK_TGZ=ON
cpack

For audio support, you must upload firmware to the device. Newer Kinect models may require audio firmware for motor and LED support. The best method is to insert firmware at runtime just after calling freenect_init().

Alternately, firmware for Kinect model 1414 can be downloaded automatically by specifying:

cmake .. -DBUILD_REDIST_PACKAGE=OFF

Note that firmware may not be legal to redistribute in your jurisdiction!

OSX

If you don't have a package manager, install Homebrew. For a manual build, see the wiki.

Homebrew

brew install libfreenect
# or get the very latest:
# brew install --HEAD libfreenect

MacPorts

sudo port install git-core cmake libusb libtool

Continue with Fetch & Build.

Linux

Remember to install the udev rules. For a manual build, see the wiki.

Ubuntu/Debian/Mint

The version packaged in Ubuntu may be very old. To install newer packaged builds, see the wiki. Continue with this section for a manual build.

sudo apt-get install git cmake build-essential libusb-1.0-0-dev

# only if you are building the examples:
sudo apt-get install freeglut3-dev libxmu-dev libxi-dev

Continue with Fetch & Build.

There is also a debian branch for packaging purposes.

Gentoo Linux

There are dev-libs/libfreenect ebuilds in the overboard repo.

Arch Linux

There is a libfreenect PKGBUILD in the AUR. Alternately, the libfreenect-git PKGBUILD builds the very latest.

Windows

As of libusb 1.0.22, libusbK isochronous transfers are now supported natively. There is no longer a need to compile a custom version of libusb.

Use Zadig to install the libusbK driver for each device you wish to use. Follow Fetch & Build or use Github and CMake GUI tools. Remember to supply paths to CMake so it can find dependencies. For example:

cmake .. -DLIBUSB_1_INCLUDE_DIR="C:\path\to\libusb\include" -DLIBUSB_1_LIBRARY="C:\path\to\libusb\libusb.lib"

Wrappers

Interfaces to various languages are provided in wrappers/. Wrappers are not guaranteed to be API stable or up to date.

  • C (using a synchronous API)
  • C++
  • C#
  • python
  • ruby
  • actionscript
  • Java (JNA)

Fakenect

Using fakenect, you can record a session to a directory and play it back later.

mkdir session
fakenect-record ./session

To use a fakenect recorded stream, just provide the fakenect lib as a pre loaded library with LD_PRELOAD and indicates the recorded files directory with FAKENECT_PATH.

  • Sample with python wrappers :
    LD_PRELOAD="/usr/local/lib/fakenect/libfakenect.so" FAKENECT_PATH="./session" python ./wrappers/python/demo_cv_sync.py
  • Sample with C bin :
    LD_PRELOAD="/usr/local/lib/fakenect/libfakenect.so" FAKENECT_PATH="./session" freenect-glview
