Delete track in multiObjectTracker
Create a track using detections in a multiObjectTracker
tracker.
tracker = multiObjectTracker
tracker = multiObjectTracker with properties: TrackerIndex: 0 FilterInitializationFcn: 'initcvkf' AssignmentThreshold: [30 Inf] MaxNumTracks: 200 MaxNumDetections: Inf MaxNumSensors: 20 OOSMHandling: 'Terminate' ConfirmationThreshold: [2 3] DeletionThreshold: [5 5] HasCostMatrixInput: false HasDetectableTrackIDsInput: false StateParameters: [1x1 struct] NumTracks: 0 NumConfirmedTracks: 0
detection1 = objectDetection(0,[1;1;1]); detection2 = objectDetection(1,[1.1;1.2;1.1]); tracker(detection1,0); tracker(detection2,1)
ans = objectTrack with properties: TrackID: 1 BranchID: 0 SourceIndex: 0 UpdateTime: 1 Age: 2 State: [6x1 double] StateCovariance: [6x6 double] StateParameters: [1x1 struct] ObjectClassID: 0 ObjectClassProbabilities: 1 TrackLogic: 'History' TrackLogicState: [1 1 0 0 0] IsConfirmed: 1 IsCoasted: 0 IsSelfReported: 1 ObjectAttributes: [1x1 struct]
Delete the first track.
