I can't launch cameracalibrator.launch #73

Open caemoon2 opened 9 years ago

caemoon2 commented 9 years ago

Hello, I'm trying to launch ptam calibrator with following some tutorial. But when I use following command,

roslaunch ptam cameracalibrator.launch

I got the next result, [cameracalibrator.launch] is neither a launch file in package [ptam] nor is [ptam] a launch file name The traceback for the exception was written to the log file

I'm really new to ROS and computer vision so I have no idea what is wrong with my computer...

http://www.hyperbolicthoughts.co.uk/2015/05/lsd-slam-install.html this is a link for the tutorial, I was following, and under the calibrate camera part, you can see the line of command and others. I think the setup of ptam was successful, because I can see the launch file under devel folder, which is under my catkin folder. So anybody can give me some advice for my issue?

Thanks in advance,

You need to run source CATKIN_DIR/devel/setup.bash where CATKIN_DIR is the location of your base catkin workspace folder.

@ssampang Thanks Ssampang, I moved one step further. However, I got different and long error, which I can't totally understand and I have no idea how to solve the error,

and when I interrupt this process by ctrl+c, I got following messages

Can anybody get some idea about this error? I don't even know what is ioctl.....

Another case, when I tried to launch the cameracalibrator with original launch file, which includes original contents,

Then I launched ~/catkin_ws$ roslaunch ptam cameracalibrator.launch

the result is ... logging to /home/moon/.ros/log/23d8f6ea-36fa-11e5-81bc-e0915376966c/roslaunch-Mubuntu-4813.log Checking log directory for disk usage. This may take awhile. Press Ctrl-C to interrupt Done checking log file disk usage. Usage is <1GB.

But I didn't see an GUI,,,, where is the guy???

I can't find any solution,, even I spend most of my time today....

thank you in advance...

Are you intending to use a webcam with ptam? It might be helpful to get a brief understanding of how ROS image topics work. They follow a publisher/subscriber model where something needs to register as a "topic" with ROS and publish images/frames under its name, which ptam will then subscribe to. That is the role of the line remap from="image" to="bluefox_ros_node/image_raw" /> in both of the .launch files. It tells ptam the name of the image topic it needs to subscribe to. I'm not 100% sure how this works with webcams as I've personally been using saved images, but you'll need to change the "image" to the name of the topic that your webcam publishes under. Hope that helps.
