Hi,

I am developing an application in DeepStream that detects and tracks trucks using YOLO detection model and the NvDCF tracker. In normal situations the application works fine, however in a specific case I have found an issue. There is a case where the truck leaves the camera and reappears in the camera a few seconds later moving backwards. In this case, the tracker is not able to keep the ID, so when the truck re-enters the camera it assigns another one:

The truck when leaves the camera:

The truck when enters the camera backwards:

Is it possible to keep the ID by changing some parameter of the NvDCF tracker?

Thank you,

Mikel

Please upgrade to the latest DeepStream 6.4 release. Please have a try with: /opt/nvidia/deepstream/deepstream-6.4/samples/configs/deepstream-app/config_tracker_NvDCF_accuracy.yml
: Gst-nvtracker — DeepStream documentation 6.4 documentation

Is there much difference between version 6.3 and 6.4 trackers?
