OpenNI traker

Intalación

Lo primero que vamos a decir es como configurar el entorno para poder trabajar con la librería skeleton tracking, para ello vamos a trabajar con ROS, la versión fuerte, para instalarlo:

sudo apt-get install ros-fuerte-desktop-full


Después de eso, para poder trabajar con la kinect, debemos instalar los drivers de openni, recordar que estamos trabajando con la versión fuerte de ros:

sudo apt-get install ros-fuerte-openni-camera ros-fuerte-openni-launch


La librería skeleton tracking, que es la que vamos a utilizar se encuentra en el paquete NITE, que puedes encontrar en el siguiente enlace: [1], debemos descargarnos la versión 1.5, ya que a partir de la versión 2.0 da problemas de compatibilidad y no conseguiremos hacer funcionar la librería skeleton tracking.

Una vez descargado lo descomprimimos y ejecutamos el fichero install.sh.

sudo ./install.sh

Debemos obtener lo siguiente:

*** DONE ***

Por último, solo nos falta instalar el paquete en cuestión openni_tracker .

sudo apt-get install ros-fuerte-openni-tracker


Ejecutando Skeleton Tracking

Debemos abrir 3 terminales diferentes:

  • En el primero, ejecutaremos ROS, para ello escribimos en linea de comandos:
roscore

y nos debe aparecer algo como esto:

... logging to /home/aitana/.ros/log/f3ff128e-5c2a-11e3-8ee4-0c6076187d47/roslaunch-aitana-laptop-3492.log
Checking log directory for disk usage. This may take awhile.
Press Ctrl-C to interrupt

started roslaunch server http://aitana-laptop:60613/

SUMMARY

PARAMETERS
 * /rosdistro
 * /rosversion

NODES

auto-starting new master

process[rosout-1]: started with pid [3521]
started core service [/rosout]

Lo dejamos corriendo en segundo plano.

  • En el segundo terminal, debemos lanzar los drivers openni para la kinect
roslaunch openni_launch openni.launch

Y una vez más, nos debe aparecer algo como lo que se muestra a continuación:

... logging to /home/aitana/.ros/log/f3ff128e-5c2a-11e3-8ee4-0c6076187d47/roslaunch-aitana-laptop-3614.log

Y que no cunda en pánico, que el error es normal.

  • Por último, abrimos un nuevo terminal y en este ejecutamos por fin:
rosrun openni_tracker openni_tracker
Una vez que se está ejecutando, nos pondremos enfrente de la kinect en pose PSI
Pose PSI
, de esta forma nos aparecerán los siguientes mensajes:
New User 1
Pose Psi detected for user 1
Calibration started for user 1
Calibration complete, start tracking user 1
Lost User 1

Lo primero que hace es detectar que hay una persona, a continuación, detecta que tiene la posición PSI y entonces comienza la calibración, si nos apartamos de la cámara entonces mostrará el mensaje que indica que ha perdido al usuario.
