Is it possible to fill a new message field in an old bag data with an incrementing counter using a bag migration rules file ( http://wiki.ros.org/rosbag/migration ) and rosbag fix?
Yep it is (as simple as it should be)! Just create a counter and increment and assign it i update()
Snippet of the migration rules class, ( see http://wiki.ros.org/rosbag/migration ) :
migrated_types = [ ]
valid = True
counter = 0
def update(self, old_msg, new_msg):
self.counter += 1
new_msg.obj_id = self.counter
