'Rosbag record' with Kinect, facing a disk memory space problem

edit

You should use the "-O /my_path/my_file" option.

Otherwise, the "-o" is also an interesting option (see rosbag record ), as it permits to append the timestamp to the filename. So if you record twice the same thing, it won't be overwritten ;-)

[EDIT] (please edit your question instead of putting a comment) as said in the help given here

-l NUM, --limit=NUM :
Only record NUM messages on each topic.

[EDIT 2] : for the

rosparam set use_sim_time true

don't forget to put it to false before recording... :-) And i would recommend you to use both the --clock and --pause option, so it loads and you can replay it when you're ready ^^

[EDIT 3] just remove the --limit=60 and you should be fine :-) Because it means you will only record 60 messages. Which, at a 30 frame/sec rate, will do 2 seconds :-) So remove this option, and record.

[EDIT 4] you put a space between the directory and filename, instead do -O /media/8676FBBC76FBAB57/my_kinect_file

[EDIT 5] otherwise, try to record each topic in a different file. I personnaly use a launch file, as show below :

 <launch>

  <!-- Parameters to change each time-->
    <arg name="depth_registration" default="true" />
    <arg name="path" default="/media/stephane/Data/Imitation_kinect" />



 <!-- Putting the time back to real time-->
    <rosparam>
       /use_sim_time : false
    </rosparam>

 <node pkg="rosbag" type="record" name="record_kinect1_rgb" args="kinect1/rgb/image_raw kinect1/rgb/camera_info -o $(arg path)/kinect1_rgb"/> 

<node pkg="rosbag" type="record" name="record_kinect2_rgb" args="kinect2/rgb/image_raw kinect2/rgb/camera_info -o $(arg path)/kinect2_rgb"/> 

<node pkg="rosbag" type="record" name="record_tf" args="tf -o $(arg path)/tf"/> 

<node pkg="rosbag" type="record" name="record_skeleton" args="/skeleton_1 /skeleton_2 -o $(arg path)/skeletons"/> 


 <!-- Saving the two kinect depth_registered if depth registration is ON -->

<group if="$(arg depth_registration)">

 <node pkg="rosbag" type="record" name="record_kinect1_depth" args="kinect1/depth_registered/image_raw kinect1/depth_registered/camera_info -o $(arg path)/kinect1_depth"/> 

 <node pkg="rosbag" type="record" name="record_kinect2_depth" args="kinect2/depth_registered/image_raw kinect2/depth_registered/camera_info -o $(arg path)/kinect2_depth"/> 

</group>

 <!-- Saving the two kinect depth if depth registration is OFF -->
<group unless="$(arg depth_registration)">

 <node pkg="rosbag" type="record" name="record_kinect1_depth" args="kinect1/depth/image_raw kinect1/depth/camera_info -o $(arg path)/kinect1_depth"/> 

 <node pkg="rosbag" type="record" name="record_kinect2_depth" args="kinect2/depth/image_raw kinect2/depth/camera_info -o $(arg path)/kinect2_depth"/> 

</group>


  </launch>

Have a good day,

Bests regards
