Kinect and other rgbd-cameras

All the rgb-d cameras we have in the lab

Libraries to use the kinect :

• to retrieve the informations from the kinect via ros opennilaunch
• detection of people via ros opennitracker
• return the position of the first user torso detected by the kinect opennitrackermodified

There is a current installation of Kinect for Windows SDK on the computer DELL.

• Joints

• Joint hierarchy

• Hierarchical bone orientation: The orientation information is provided in form of quaternions and rotation matrices for use in different animation scenarios.

Bone rotation is stored in a bone’s child joint. For example, the rotation of the left hip bone is stored in the Hip Left joint. In the hierarchical definition, the rotation of the Hip Center joint provides the absolute orientation of the player in camera space coordinates. This assumes that the player object space has the origin at the Hip Center joint, the y-axis is upright, the x-axis is to the left, and the z-axis faces the camera.

This paragraph explains how to install the legacy SR300 on recent Linux systems.

• Support for the retired SR300 camera model ended after librealsense 2.50.0. So you should compile version 2.50.0 in order for the SR300 to be detected. (https://github.com/IntelRealSense/librealsense/releases/tag/v2.50.0)

• Librealsense comes with two backend:

1. The “native” backend is a Linux kernel driver. It is therefore very dependent on the kernel to run (the latest one (I wrote this in Sept. 2025) is for Linux 6.8.0, the one for legacy Realsense devices is for Linux 4.4)
2. The “libuvc” backend uses the standard uvc+hid kernel drivers and does the job in userland via the standard libuvc library. It is possibly less efficient (latency), but it is much more flexible and mostly independent of Linux kernel version.

So, the idea is to compile librealsense v2.50.0 with the libuvc backend. The following is freely adapted from libuvc_installation.sh (https://github.com/IntelRealSense/librealsense/blob/master/scripts/libuvc_installation.sh#L35-L39)

• Compile & Install

    wget https://github.com/IntelRealSense/librealsense/archive/refs/tags/v2.50.0.tar.gz
    tar xvf v2.50.0.tar.gz
    cd ./librealsense-2.50.0
 
    sudo cp config/99-realsense-libusb.rules /etc/udev/rules.d/ 
    sudo udevadm control --reload-rules && sudo udevadm trigger 
 
    sudo apt-get install -y git cmake libssl-dev freeglut3-dev libusb-1.0-0-dev pkg-config libgtk-3-dev
    mkdir build && cd build
    cmake ../ -DFORCE_LIBUVC=true -DCMAKE_BUILD_TYPE=release
    make -j2
    sudo make install

• Tips: In case compilation fails on some non-essential SDK functionnalities, try to add one or several of the following compilation options on the cmake command line: `-DCHECK_FOR_UPDATES=OFF` `-DBUILD_EXAMPLES=OFF` `-DBUILD_TOOLS=OFF`
