Hi Mathieu,

Unfortunately, I do not have the bag available.

But now I want to give this another try with multiple cameras this time, I have a VLP16 lidar and 4 non-overlapping & calibrated cameras producing 4 rgb topics and 4 camera info topics. The logic again is to create a 3D point cloud through lidar-based slam and then paint the map from the images.

I get the part that you use the nodelets to synchronize them but it is not exactly clear to me how to make this work. For example, at the experiment I did before when I was using a singe rgb topic and the lidar all I did was simply to set "rgb_topic:=/image_topic and camera_info_topic:=/camera_info_topic" and this was enough. Now what should I twick? As always, any recommendation is highly appreciated.

With respect,
Antonis.
