ros kinect rosrun openni_tracker openni_tracker [closed]

edit

Hi I have done that, first I run roscore in a terminal then I run rosrun openni_tracker openni_tracker in different terminal, but nothing happens, it just hangs

Ok are you able to run rosrun openni_camera openni_node? Are you having the problem only with this node. Check the other packages like turtlesim, gazebo.

well, I can run rosrun turtlesim turtlesim_node,......., rosrun rviz rviz,.......,rosrun image_view disparity_view image:=/camera/depth/disparity,.......,rosrun image_view image_view image:=/camera/rgb/image_color,...., however I can not run rosrun openni_tracker openni_tracker,.....,if I want to run the point cloud node, it must be like this rosrun image_view image_view image:=/camera/depth/points,,,,,right?

it seems your ROS installation is fine. But the openni_tracker has the problem. When you say nothing happens, is it with the above mentioned error or you see blank terminal with no msgs after you type the run command.?

Try checking the rostopic list and see if something is publishing. You can also check this with rxgraph.

Well, when I run rosrun openni_tracker openni_tracker,, I get a blank terminal,,, then in a new terminal I run rxgraph and I get /openni_tracker->/rosout->/rosout

and in the info I get Node [/openni_tracker] Publications: * /rosout [rosgraph_msgs/Log] Subscriptions: None Services: * /openni_tracker/get_loggers * /openni_tracker/set_logger_level Pid: 1887 Connections: * topic: /rosout * to: /rosout * direction: outbound * transport: TCPROS
