Creating a dataset for Visual Inertial Odometery

Hi again,

I am creating a dataset to be used in tightly coupled VIO. I will be storing the data over ROS1 in a ROS bag. I need the IMU data to be synchronized which we already established to do by setting the sensors_timestamp_sync to true, now is it enough to use the ZED-Node and subscribe to the topics: left_raw/image_raw_color and right_raw/image_raw_color? Or To have the images in sync properly, I should use the ZED-nodelet ( rgbd_sensors_sync_nodelet) ?

Thanks a lot.
