cnspy-rosbag2csv 0.2.6

ROS1 rosbag to CSV file converter and vice versa.

cnspy_rosbag2csv -- Package

A package to convert different [ROS1] messages for POSES. Messages contained in rosbag files can be converted into CSV files in different output formats using ROSBAG2CSV. The other way round is supported by the class CSV2ROSbag, taking multiple CSV files and writing them into a single bag file.

The supported ROS1 message types are defined in ROSMessageTypes (basically all ROS1 geometry_msgs).

The package is easily extendable (Open-Closed-Principle). Just create a new ROSMessageType, and make an addition to

• ROSMsg2CSVLine
• CSVLine2ROSMsg

The supported CSV formats for poses are defined in the enum CSVFormatPose of the package cnspy_spatial_csv_formats.
