Question about motion model #7

Open amitgalor18 opened 2 years ago

amitgalor18 commented 2 years ago

Hi, I noticed that the config file (detracker_reidV3.yaml) contains a parameter about a motion model. I see that it is imported into the parameters of each new track (line 132 in track.py) but I don't see where this parameter is actually used, for example when predicting the new position of a track before the linear matching. I also noticed that in the function tracks_dets_matching_tracking() function there is an update to the current track position but the line "t.prev_pos = t.pos" is commented out (line 184 in tracker.py).

Are you using the velocity/motion information in some other part of the code or did you decide not to use this information at all?

Hi,

Thanks for your comment. No, we don't use any motion model. The motion hyperparameters are inherited from the code of Tracktor and it is not used in this work.

Thank you for your quick reply, now it makes sense.
