Proper syntax for camera_info_url paramaeter #107

Open pitosalas opened 3 years ago

pitosalas commented 3 years ago

I am using this in my .launch file

<param name="camera_info_url" value="package://gpg_bran/camera_info/camerav2_1280x960.yaml"/>

And yet I am getting this error message:

[ INFO] [1603729230.468427408]: Unable to open camera calibration file [/home/pi/.ros/camera_info/camerav2_1280x960.yaml] [ WARN] [1603729230.468570167]: Camera calibration file /home/pi/.ros/camera_info/camerav2_1280x960.yaml not found.

Can you clarify how the value= for this param is interpreted? Thanks!

Yeah I think I've had a similar issue in the past, something isn't set up right in the pi images for the package:// syntax resolution. The file:/// syntax does work but you have to specify the entire path.

Thanks. I wish there was a tad more documentation. For example the node looks for a "default" camera_info file and a "specific" one. Not sure why. Thanks though I've gotten it to work.
