hi all, how to use door_handle_detector ( to detect a door or a handle?

i plugin kinect in the PC,and try this command in terminal:

roslaunch door_handle_detector door_closed_40.launch

(there are lots of *.lauch ,


i don't konw which one to use ,so i random select one to see what result will be)

BUT,i get ERROR as follows:

FATAL] [1318863811.703771799]: Failed to open file: /opt/ros/diamondback/stacks/pr2_doors/door_handle_detector/test/door_closed_40.bag (Error opening file: /opt/ros/diamondback/stacks/pr2_doors/door_handle_detector/test/door_closed_40.bag) [rosplay-6] process has died [pid 21335, exit code 1]. log files: /home/mochen/.ros/log/2d2db2aa-f8d1-11e0-8185-00218545f6b8/rosplay-6*.log

roslaunch door_handle_detector door_handle_detector_vision.xml

get an error:

core service [/rosout] found
ERROR: cannot launch node of type [stereo_image_proc/stereoproc]:

The launch file you are using is in the "test" folder, and does not appear to be up to date. It looks like its using the old rosbag commands for playing test data. If you want to use that test data, you should use something like this

<node pkg="rosbag" type="rosplay" name="rosplay" args="-r 0.5 -b 100 $(find door_handle_detector)/test/door_closed_daniel.bag"/>

However, if you want a live door detection, try one of the launch files from the launch directory, like door_hand_detector_vision.xml
