Scanner¶
ROS bag file sets¶
-
marv_robotics.bag.
scan
(dirpath, dirnames, filenames)[source]¶ Scan for sets of ROS bag files.
Bags suffixed with a consecutive index are grouped into sets:
foo_0.bag foo_1.bag foo_3.bag foo_4.bag
results in:
foo [foo_0.bag, foo_1.bag] foo_3 [foo_3.bag] foo_4 [foo_4.bag]
In this example the bag with index 2 is missing which results in foo_3 and foo_4 to be individual sets with one bag each.
The timestamps used by
rosbag record
are stripped from the name given to sets, but are kept for the remaining individual sets in case a bag is missing:foo_2018-01-12-14-05-12_0.bag foo_2018-01-12-14-45-23_1.bag foo_2018-01-12-14-55-42_3.bag
results in:
foo [foo_2018-01-12-14-05-12_0.bag, foo_2018-01-12-14-45-23_1.bag] foo_2018-01-12-14-45-23_1 [foo_2018-01-12-14-45-23_1.bag] foo_2018-01-12-14-55-42_3 [foo_2018-01-12-14-55-42_3.bag]
