Introduction

Training Technology Lab uses MATLAB for most data processing and visualization purposes. Several scripts have been written to work with our various technology. Here is a list of the following scripts:

  • Rosbag extraction
    • Rosbag loader
    • Rosbag plotter
    • Rosbag video

Rosbag extraction

For viewing video stored in a .bag file, rqt_bag is the standard tool. For extracting video

Rosbag loader

Converts .bag files into .mat files. Must be done before using the other 2 scripts

Rosbag plotter

Automatically plots known data formats)

Rosbag video

Automatically converts rosbags into .avi files with data plot overlays.


FAQ/Debugging

This sections relates to all common problems with the software. To extract video (which are just compressed/uncompressed images) several methods exist. We have often used bag2video.
