ar_pose with several cameras

edit

Hello everybody,

I'm trying to use ar_pose to detect the position of a marker. I'm interested into use more than one camera. My idea is to run one ar_pose node for every camera.

Since now I've been able to run it only by one camera provided that the ar_pose use the topic /camera/camera_info and /camera/image_raw to construct its tf's. I achieve the camera toppic by doing remaping form usb_cam nodes.

Since I'm not able to do remaping to the same topic for every camera, my question is: How can I do to use several ar_pose nodes from diferent image streams?

I have been reading some answers related with ar_pose_ekf but i'm not been able to find the package on the wiki.

Thank you in advance.
