Hi guys!

I have a stereo camera (stereolabs ZED) broadcasting on the following:

[ INFO] [1446766235.485123283]: Advertized on topic rgb/image_raw
[ INFO] [1446766235.494671404]: Advertized on topic depth/image_raw
[ INFO] [1446766235.495143958]: Advertized on topic /camera/rgb/camera_info
[ INFO] [1446766235.495611184]: Advertized on topic /camera/depth/camera_info


and I have modified the rgbd_mapping.launch file to reflect these facts.

I am running through the handheld mapping tutorial, and i get the error:

[ WARN] [1446768388.774197693]: Could not get transform from camera_link to /zed_rgb_optical_frame after 1 second!

any idea what I could do? I understand its an issue with tf ? any help is super appreciated!
