matmot

This package provides some simple tools for streaming rigid body and marker data from Motive to disk, using OptiTrack's NatNet MATLAB client.

Tasks handled

• Streaming from Motive to disk (Streamer.m)
• Loading previously streamed data into MATLAB (loadMtvFile.m)
• Identifying LEDs pulses for synchronization (extractSyncPulses.m)

Requirements/dependencies

• MATLAB r2017a or later
• MATLAB logging framework
• NaturalPoint Motive software (tested on v2, but should also work with v1)

Setup

• Clone this repository and place it on your MATLAB path
• Install the MATLAB logging framework
• Configure your Motive software to broadcast tracking data in "multicast" mode

Quick example script

Once you've followed the setup instructions above, you can acquire data as demonstrated by this example code snippet:

% Create a Streamer object and acquire 60 seconds of data from 2 rigid bodies and 20 markers
streamer = matmot.Streamer('nRigidBodies', 2, 'nMarkers', 20);
streamer.start();
pause(60);
streamer.finish();

After finishing streaming, the data on disk can be loaded into MATLAB with the function loadMtvFile().
