Hi all, I'm currently trying to use the ROS image_pipeline and the new camera1394 driver to get some Point Grey 1394 cameras up and running. For some reason, I am unable to view any of the topic being published by image_proc. First, here is the launch file I am using to start up the camera and image_proc: After running this, I get the following output from rostopic list -v: Published topics: * /left/camera/image_rect_color [sensor_msgs/Image] 1 publisher * /left/camera/image_rect [sensor_msgs/Image] 1 publisher * /left/camera/camera_info [sensor_msgs/CameraInfo] 1 publisher * /rosout [roslib/Log] 2 publishers * /left/camera/image_raw [sensor_msgs/Image] 1 publisher * /rosout_agg [roslib/Log] 1 publisher * /left/camera/image_color [sensor_msgs/Image] 1 publisher * /left/camera/image_mono [sensor_msgs/Image] 1 publisher Subscribed topics: * /clock [unknown type] 3 subscribers * /rosout [roslib/Log] 1 subscriber So, based on that, I can see that the image_proc node is actually up and running. I am able to do "rosrun image_view image_view image:=/left/camera/image_raw" and see the color image from my camera streaming in. rostopic hz also confirms that both /left/camera/image_raw and /left/camera/camera_info are running at about 15 fps. Now, when I run "rosrun image_view image_view image:=/left/camera/image_rect_color" (or any other image_proc published topic), I get a blank window with no image in it. Running rostopic list -v again while the image_view node is running gives me the following: Published topics: * /left/camera/image_rect_color [sensor_msgs/Image] 1 publisher * /left/camera/image_rect [sensor_msgs/Image] 1 publisher * /left/camera/camera_info [sensor_msgs/CameraInfo] 1 publisher * /rosout [roslib/Log] 3 publishers * /left/camera/image_raw [sensor_msgs/Image] 1 publisher * /rosout_agg [roslib/Log] 1 publisher * /left/camera/image_color [sensor_msgs/Image] 1 publisher * /left/camera/image_mono [sensor_msgs/Image] 1 publisher Subscribed topics: * /left/camera/image_rect_color [sensor_msgs/Image] 1 subscriber * /clock [unknown type] 4 subscribers * /left/camera/camera_info [sensor_msgs/CameraInfo] 1 subscriber * /rosout [roslib/Log] 1 subscriber * /left/camera/image_raw [sensor_msgs/Image] 1 subscriber So, I can see that image_proc is subscribing to the correct topics and image_view is also on the correct topic. I also tried starting the image_proc node from the command line as indicated at http://www.ros.org/wiki/image_proc but got the exact same behavior as with the launch file. In either case, rostopic hz /left/camera/image_rect_color just outputs that it is subscribing to the topic and waits. I'm pretty sure the camera is properly calibrated, as I just finished calibrating it using the directions at http://www.ros.org/wiki/camera_calibration/Tutorials/MonocularCalibration and it worked fine and output a .yaml file when I hit upload in the calibration GUI. rostopic echo on the /left/camera/camera_info topic gives me the values that are in the calibration file. I'm assuming that even if the calibration were somehow off, I should still at least see the image_pipeline attempting to display an image_rect_color topic. So, I'm a bit stumped as to what to do to narrow down what is causing this behavior, since I get no error output in any of my terminal windows. I'm running the latest based on these .rosinstall files: http://ros.org/rosinstalls/latest_pr2.rosinstall with http://www.ros.org/rosinstalls/wg_latest_devel.rosinstall in an overlay. Are there some steps I can take to try to debug this problem? Has anyone else experienced this type of issue with the new camera1394 driver?
