Single-hypothesis track-to-track fuser
The trackFuser
System object™ fuses tracks generated by tracking sensors or trackers and architect
decentralized tracking systems. trackFuser
uses the global nearest neighbor
(GNN) algorithm to maintain a single hypothesis about the objects it tracks. The input tracks
are called source or local tracks, and the
output tracks are called central tracks.
To fuse tracks using this object:
Create the trackFuser
object and set its properties.
Call the object with arguments, as if it were a function.
To learn more about how System objects work, see What Are System Objects?.
creates a track-to-track
fuser that uses the global nearest neighbor (GNN) algorithm to maintain a single
hypothesis about the objects it tracks. fuser
= trackFuser
sets properties for the fuser using one or more name-value pairs. Unspecified properties
have default values. Enclose each property name in single quotes.fuser
= trackFuser(Name,Value
)
returns a list of confirmed tracks from a list of local tracks. Confirmed tracks are
predicted to the update time, confirmedTracks
= fuser(localTracks
,tFusion
)tFusion
.
[
also returns a list of tentative tracks, a list of all tracks, and the analysis
information.confirmedTracks

)
To use an object function, specify the
System object as the first input argument. For
example, to release system resources of a System object named obj
, use
this syntax:
release(obj)
