Create a Python pandas data frame from a ros bag file
RosbagPandas provides a quick way to load rosbag files into a Pandas Dataframe object for data viewing and manipulation. Usage is similar to the following:
#!/usr/bin.env python import rosbag_pandas
dataframe = rosbag_pandas.bag_to_dataframe(‘file.bag’) #awesome data processing
In addition to parsing and taking in the whole bag the function can use the include and exclude parameters to limit the topics read into the dataframe.
Examples include using a regular expression to filter or add topics as well as filtering or adding from a list.
Also installs two scripts:
bag_graph.py which allows a user to produce a quick graph of data in a bag file.
bag2csv.py allows a user to quickly convert data in a rosbag into csv format.
