Hi,
I am using several trackerGNN to form tracks on simulated measurements. Each trackerGNN initialization corresponds to a new sensor. That is,
for jj=1:nSensors
sensors(jj).tracker = trackerGNN('FilterInitializationFcn',@initcvkf,'ConfirmationThreshold',[4 5],'DeletionThreshold',10);
end
I would like to then fuse these tracks across the sensors.
nSensors = nCombine;
internalSource1 = fuserSourceConfiguration(1,'IsInternalSource',true);
internalSource2 = fuserSourceConfiguration(2,'IsInternalSource',false);
fuser = trackFuser('MaxNumSources',2,'SourceConfigurations',{internalSource1;internalSource2},'StateFusion','Cross');
fusedTracks = fuser(localTracks,ii);
To do this, I need to have a defined SourceIndex for each track point, I think. How do I set this SourceIndex? I would like to do it initially such as when I call trackerGNN but I cant seem to get that to work.
Thanks

Hi Ryan,
trackerGNN has "TrackerIndex" property that controls the SourceIndex of the output tracks.
See the property documentation below for more information.
Multi-sensor, multi-object tracker using GNN assignment - MATLAB (mathworks.com)
Thanks,
Prashant
