fusion.trackingArchitecture.Tracker Class

Interface definition for trackingArchitecture tracker

Since R2021a

Description

The fusion.trackingArchitecture.Tracker abstract class defines the interface for a tracker used in the trackingArchitecture System object. To custom a tracker class used in the trackingArchitecture System object, create a class that inherits from the fusion.trackingArchitecture.Tracker class. The class definition must have this format,

classdef customTrackerClass < fusion.trackingArchitecture.Tracker

where customTrackerClass is the name of your custom tracker class.

The custom class must implement these Properties and Methods. To add the customized tracker to a tracking architecture, use the addTracker function.

The fusion.trackingArchitecture.Tracker class is a handle class.

Methods

Public Methods

step	confirmedTracks = step(trackerObj,detections,time) runs the tracker based on the detections input and the simulation time input. It also returns the confirmed tracks. trackerObj — The tracker object. detections — Object detections, specified as an array of objectDetection objects, a cell array of objectDetection objects, or an array of structures. If specified as structures, the field names of each structure must be the same as the property names of the objectDetection object. time — Simulation time, specified as a nonnegative scalar. The tracker predicts all tracks to the specified time. Abstract true
isLocked	tf = isLocked(trackerObj) determines if the tracker is in use. trackerObj — The tracker object. tf — Indicate if the tracker is stepped, returned as true or false. Abstract true
reset	reset(trackerObj) resets the internal states of the tracker object trackerObj. Abstract true
release	release(trackerObj) releases system resources such as memory, file handles, or hardware connections, and allows you to change properties and input characteristics of the tracker object trackerObj. Abstract true
clone	clonedTracker = clone(trackerObj) creates a copy clonedTracker that has the same property values and states as the tracker object trackerObj. Abstract true
