Utilisation Ros de Thomas: notice et remarques en fin de stage (août 2018)

compilation de tous les noeuds

cd /home/tdedieu/catkin_ws/
catkin_make

noeud camera:

roscd ueye_cam/

pour banc stereo + camera scene

roslaunch ueye_cam master_slaves_tdedieu.launch

ou pour camera scene seule

roslaunch ueye_cam master_slaves_rgb8.launch

pour visualiser /scene/image_raw

roslaunch ueye_cam view_scene.launch 
roslaunch ueye_cam view_stereo.launch  
roslaunch ueye_cam view_me.launch 

roscd eye_tracker/ pwd

/home/tdedieu/catkin_ws/src/eye_tracker
roslaunch eye_tracker eye_tracker_dedieu_stereo.launch 

cd src/

atom eye_tracker_nodelet.cpp &

eye_tracker echoue si image trop sombre: augmenter la duree d'exposition et/ou baisser le frame rate dans le script launch:

master_slaves_tdedieu.launch
  <param name="exposure" type="double" value="100.0" />
<param name="frame_rate" type="double" value="30.0" /> <!-- frame rate settings are ignored in camera_ext_trigger_mode -->

pour visualiser les ellipses extraites

 roslaunch eye_tracker view_pupils.launch

pour detection des tags:

roslaunch camera_scene_detection scene.launch

roscd camera_scene_detection/

cd src/  
atom camera_scene_detection_nodelet.cpp &

noeud optimisation stereo: (dans le paquet eye_tracker) eye_tracker →MainTriangulatePupils les messages pupilles sont connus grace a import pupil2D as p2d definis dans /home/tdedieu/catkin_ws/src/eye_tracker/msg/Pupil_2D.msg

actuellement le noeuds attend 1 message par camera →probleme de synchro → il faudra faire un nodelets qui recupere les pixels candidats pour les 2 cameras et les met dans un seul message.

roslaunch eye_tracker eye_tracker_dedieu_stereo.launch 

et

roslaunch eye_tracker tri_eye_tracker_stereo.launch

pour la synchronisation des messages:

ajouter en sudo nano /opt/ros/kinetic/lib/python2.7/dist-packages/message_filters/__init__.py
