Confirming a confirmed track for GNN tracker

Hi, I am currently working with a GNN tracker with radar data. I have a tracker working for range and angle information.

After gettting the confirmed tracks, I would like to check make another check with some detections and then keep the old track alive. How can I achieve this? I saw that there is a trackStateLogic which is appended with a zero everytime a track does not get a detection. But I was uable to change it for a confirmed track.

Can someone please help me in this?

Hi @Sarfaraz,

The “trackStateLogic" parameter is used to specify the confirmation and deletion logic type for a trackerObject and is nontunable as per the documentation here:

To keep the old tracks alive, a possible workaround is to use “confirmTrack" on the trackerObject and re-initializing if needed using "initializeTrack"of deleted trackerObjects, Please refer the documentation link below to learn more about Object functions on trackerGNN:
