| |
| − | Training Technology Lab uses MATLAB for most data processing and visualization purposes.
| |
| − | Several scripts have been written to work with our various technology. <br>
| |
| − | Here is a list of the projects:
| |
| − |
| |
| − | * Rosbag extraction
| |
| − | * EMG analyzer
| |
| − | * Bluetooth force sensor
| |
| − | * RTL MATLAB control
| |

| |
| − | [[File:MATLAB dualvideo example.png|600px|thumb|right|'''rosbag_video.m''' example - using two webcam feeds.]]
| |
| − |
| |
| − | '''Official methods:''' <br>
| |
| − | Viewing: For viewing video stored in a .bag file, [http://wiki.ros.org/rqt_bag rqt_bag] is the standard tool.
| |
| − |
| |
| − | Extraction: To extract video (which are just compressed/uncompressed images) several methods exist. We have often used [https://github.com/OSUrobotics/bag2video bag2video].
| |
| − |
| |
| − | === MATLAB scripts: ===
| |
| − | '''rosbag_loader.m'''
| |
| − | Converts .bag files into .mat files. Must be done before using the other 2 scripts
| |
| − |
| |
| − | '''rosbag_plotter.m'''
| |
| − | Automatically plots known data formats)
| |
| − |
| |
| − | '''rosbag_video.m'''
| |
| − | Automatically converts rosbags into .avi files with data plot overlays.<br>
| |
| − | It can use single or dual videos and plot up to 4 data sets.
| |
| − |
| |
| − |
| |
| − | Usage:
| |
| − | 1. Make a new folder with the same name as the ROSBAG-file you intend to analyze.
| |
| − | 2. Paste in the ROSBAG-file and a copy of rosbag_loader.m(which can be found in one of the other folders)
| |
| − | 3. Run rosbag_loader and chosse the desired .bag file. This will save the data as a workspace file in the new folder
| |
| − | 4. Run rosbag_plotter and choose the desired .m file, to plot the data.
| |
| − |
| |
| − | == EMG analyzer ==
| |
| − | For analyzing EMG data recorded with Myon electrodes and ADInstruments AD converter via ROS-setup in Training Technology Lab
| |
| − |
| |
| − | == Bluetooth force sensors ==
| |
| − |
| |
| − | == ROS MATLAB control ==
| |
| − | An initial attempt to control the RTL from MATLAB. The idea was to make programming the RTL and make data acquisition easier for Veltek students.
| |
| − | A MATLAB GUI was supposed to be the interface. This project is not finished.
| |
| − |
| |
| − | == BFR audio ==
| |
| − | A simple test script for listening to sound from arteries during blood flow restriction exercise.
