Thank you for explaining how the feature extraction works and why it’s possible for these tracking ids stay in “active tracking mode”. Your insight has really helped.
Am I able to pull the nvtracker meta data from NvDsBatchMeta ? I want to pull all the tracking meta such as tracking ids, tracking confidence levels, and tracking Id age. So I can account for trackers that are in shadow mode as well as the “active” ones.
If i pull object_id from object meta i only can recieve the “active tracking id” and the confidence from nvinfer.
I’ve checked the dev guides, but I’m not sure what the meta class is for NvMOTTrackerMeta.
I understand object meta. In a probe I I through the frame meta, then to object meta list, and finally grab all the object meta in the frame .
Psuedo code looks a little like this
(Loop)
frame_meta → object_meta_list; l_obj → data.
class_id = obj_meta.class_id
…
I dont understand where it is in the metadata struct tho. I’ve tried to search for tracking_id and tracking_confidence. It doesnt exist in frame_meta or object_meta. So how can I retrieve it ?
According to this document, there is a data struct that I could potentially use to grab nvtracker meta.
