Tracker object ID mapping between two cameras

[adityawasnik91]

Please provide complete information as applicable to your setup.

• Hardware Platform (Jetson / GPU) :- Jetson Orin NX
• DeepStream Version :- 7
• JetPack Version (valid for Jetson only) :- 6

I have a deepstream pipeline that looks something like this.

appsrc1 -> 
          streammux -> pgie -> tracker -> sink. 
appsrc2 -> 

The appsrc are taking images coming from two different cameras. These cameras do no give RTSP, hence using appsrc.

my camera setup:-

[1] One camera has a 0 to 300 meters FOV and other camera has 0 to 80 meters FOV. 
[2] Both cameras are looking at the same direction 
Imagine a straight road, both cameras are looking towards the same direction, so there is overlapping area in the FOV of both cameras. 

i want to map the tracker object ID between the two cameras.
is there any way that this can be done?

I have tried to sync the two cameras to the best way possible.

Seems you want MTMC like here: NVIDIA Multi-Camera Tracking AI Workflow But MTMC only support dGPU currently.

yes something like this, but cant use this as I have to deploy this on jetson.
any other way ?

MTMC only works on dGPU. We haven’t MTMC on Jetson currently.
