Description

Driver for Kinect for Windows v2 (K4W2) devices (release and developer preview).

Note: libfreenect2 does not do anything for either Kinect for Windows v1 or Kinect for Xbox 360 sensors. Use libfreenect1 for those sensors.

If you are using libfreenect2 in an academic context, please cite our work using the following DOI: DOI

If you use the KDE depth unwrapping algorithm implemented in the library, please also cite this ECCV 2016 paper.

This driver supports:

  • RGB image transfer
  • IR and depth image transfer
  • registration of RGB and depth images

Missing features:

Watch the OpenKinect wiki at www.openkinect.org and the mailing list at https://groups.google.com/forum/#!forum/openkinect for the latest developments and more information about the K4W2 USB protocol.

The API reference documentation is provided here https://openkinect.github.io/libfreenect2/.

Requirements

Hardware requirements

  • USB 3.0 controller. USB 2 is not supported.

Intel and NEC USB 3.0 host controllers are known to work. ASMedia controllers are known to not work.

Virtual machines likely do not work, because USB 3.0 isochronous transfer is quite delicate.

Requirements for multiple Kinects

It has been reported to work for up to 5 devices on a high-end PC using multiple separate PCI Express USB3 expansion cards (with NEC controller chip). If you're using Linux, you may have to increase USBFS memory buffers. Depending on the number of Kinects, you may need to use an even larger buffer size. If you're using an expansion card, make sure it's not plugged into an PCI-E x1 slot. A single lane doesn't have enough bandwidth. x8 or x16 slots usually work.

Operating system requirements

  • Windows 7 (buggy), Windows 8, Windows 8.1, and probably Windows 10
  • Debian, Ubuntu 14.04 or newer, probably other Linux distros. Recommend kernel 3.16+ or as new as possible.
  • Mac OS X

Requirements for optional features

  • OpenGL depth processing: OpenGL 3.1 (Windows, Linux, Mac OS X). OpenGL ES is not supported at the moment.
  • OpenCL depth processing: OpenCL 1.1
  • CUDA depth processing: CUDA (6.5 and 7.5 are tested; The minimum version is not clear.)
  • VAAPI JPEG decoding: Intel (minimum Ivy Bridge or newer) and Linux only
  • VideoToolbox JPEG decoding: Mac OS X only
  • OpenNI2 integration: OpenNI2 2.2.0.33
  • Jetson TK1: Linux4Tegra 21.3 or later. Check Jetson TK1 issues before installation. Jetson TX1 is not yet supported as the developers don't have one, but it may be easy to add the support.

Troubleshooting and reporting bugs

First, check https://github.com/OpenKinect/libfreenect2/wiki/Troubleshooting for known issues.

When you report USB issues, please attach relevant debug log from running the program with environment variable LIBUSB_DEBUG=3, and relevant log from dmesg. Also include relevant hardware information lspci and lsusb -t.

Installation

Windows / Visual Studio

  • Install UsbDk driver

    1. (Windows 7) You must first install Microsoft Security Advisory 3033929 otherwise your USB keyboards and mice will stop working!
    2. Download the latest x64 installer from https://github.com/daynix/UsbDk/releases, install it.
    3. If UsbDk somehow does not work, uninstall UsbDk and follow the libusbK instructions.

    This doesn't interfere with the Microsoft SDK. Do not install both UsbDK and libusbK drivers

  • (Alternatively) Install libusbK driver

    You don't need the Kinect for Windows v2 SDK to build and install libfreenect2, though it doesn't hurt to have it too. You don't need to uninstall the SDK or the driver before doing this procedure.

    Install the libusbK backend driver for libusb. Please follow the steps exactly:

    1. Download Zadig from http://zadig.akeo.ie/.
    2. Run Zadig and in options, check "List All Devices" and uncheck "Ignore Hubs or Composite Parents"
    3. Select the "Xbox NUI Sensor (composite parent)" from the drop-down box. (Important: Ignore the "NuiSensor Adaptor" varieties, which are the adapter, NOT the Kinect) The current driver will list usbccgp. USB ID is VID 045E, PID 02C4 or 02D8.
    4. Select libusbK (v3.0.7.0 or newer) from the replacement driver list.
    5. Click the "Replace Driver" button. Click yes on the warning about replacing a system driver. (This is because it is a composite parent.)

    To uninstall the libusbK driver (and get back the official SDK driver, if installed):

    1. Open "Device Manager"
    2. Under "libusbK USB Devices" tree, right click the "Xbox NUI Sensor (Composite Parent)" device and select uninstall.
    3. Important: Check the "Delete the driver software for this device." checkbox, then click OK.

    If you already had the official SDK driver installed and you want to use it:

    1. In Device Manager, in the Action menu, click "Scan for hardware changes."

    This will enumerate the Kinect sensor again and it will pick up the K4W2 SDK driver, and you should be ready to run KinectService.exe again immediately.

    You can go back and forth between the SDK driver and the libusbK driver very quickly and easily with these steps.

  • Build libusb

    Open a Git shell (GitHub for Windows), or any shell that has access to git.exe and msbuild.exe

    cd depends/
.\install_libusb_vs2013.cmd

    Or install_libusb_vs2015.cmd. If you see some errors, you can always open the cmd files and follow the git commands, and maybe build libusb_201x.sln with Visual Studio by hand. Building with "Win32" is not recommended as it results in lower performance.

  • Install TurboJPEG

    Download from http://sourceforge.net/projects/libjpeg-turbo/files, extract it to c:\libjpeg-turbo64 or depends/libjpeg-turbo64, or anywhere as specified by the environment variable TurboJPEG_ROOT.

  • Install GLFW

    Download from http://www.glfw.org/download.html (64-bit), extract as depends/glfw (rename glfw-3.x.x.bin.WIN64 to glfw), or anywhere as specified by the environment variable GLFW_ROOT.

  • Install OpenCL (optional)

    1. Intel GPU: Download "Intel® SDK for OpenCL™ Applications 2016" from https://software.intel.com/en-us/intel-opencl (requires free registration) and install it.

  • Install CUDA (optional, Nvidia only)

    1. Download CUDA Toolkit and install it. NOTE: CUDA 7.5 does not support Visual Studio 2015.

  • Install OpenNI2 (optional)

    Download OpenNI 2.2.0.33 (x64) from http://structure.io/openni, install it to default locations (C:\Program Files...).

  • Build

    The default installation path is install, you may change it by editing CMAKE_INSTALL_PREFIX.

    mkdir build && cd build
cmake .. -G "Visual Studio 12 2013 Win64"
cmake --build . --config RelWithDebInfo --target install

    Or -G "Visual Studio 14 2015 Win64".

  • Run the test program: .\install\bin\Protonect.exe, or start debugging in Visual Studio.

  • Test OpenNI2 (optional)

    Copy freenect2-openni2.dll, and other dll files (libusb-1.0.dll, glfw.dll, etc.) in install\bin to C:\Program Files\OpenNI2\Tools\OpenNI2\Drivers. Then run C:\Program Files\OpenNI\Tools\NiViewer.exe. Environment variable LIBFREENECT2_PIPELINE can be set to cl, cuda, etc to specify the pipeline.

Mac OSX

Use your favorite package managers (brew, ports, etc.) to install most if not all dependencies:

  • Make sure these build tools are available: wget, git, cmake, pkg-config. Xcode may provide some of them. Install the rest via package managers.
