How to publish a XML?
Hi all,
I'm a noob in ROS and I have a question about how to publish a xml.
This is the background: I've got two ROS nodes in one package. One node is to calibrate a camera and the other to compute the BirdsEyeView-Transformation of a capture from a camera.
The BirdsEyeView-Transformation needs to have access to the intrinsic matrix and the distortion coeffs which are calculated in the calibration node.
For me it's really hard to get useful information about ros as nobody is there to ask and mostly the information found on internet don't really fit to my problems.
First question: The calibration node is executed only once. If I publish my distortion and intrinsic XML's one time and then the calibration node is shut down: Am I able to have access to the published XML's with the transformation node after the calibration node already has shut down?
Second question: If the XML's are still avaible after the publishing node has shut down, could you help me for writing the definition of the publisher?
Thanks in advance,
Marvin
