Hi, I am asking are there any reference for us to see how to add vehicletypenet and vehiclemakenet into the deepstream application along with the LPR application. It will contain a total of 5 models (Trafficcamnet, LPDnet,LPRnet, VehicleMakeNet, VehicleTypeNet).

If VehicleMakeNet and VehicleTypeNet is added, does it mean that the unique id getting from pyds.NvDsObjectMeta.cast() will have 4types, such as 0 for the output of trafficcamnet, 1 for output of LPDnet, 2 for output for vehiclemakenet, etc.

Besides, if the tracker is added on the pgie (trafficcamnet), instead of writing the logic myself, are there any samples/plugins to use so that the trackingID can be sync with the other models together?

deepstream_lpr_app already supports Trafficcamnet, LPDnet and LPRnet, \opt\nvidia\deepstream\deepstream-7.0\sources\apps\sample_apps\deepstream-test2 already supports VehicleMakeNet, VehicleTypeNet. you can combine these two samples.
when one object is detected, on metadata will added. LPRnet, VehicleMakeNet, VehicleTypeNet are classification model, there only modify the objectmeta.
if if the tracker is added on the pgie, the object will have an unique trackerid. In the consecutive two frames, the same object has the same trackerid. what do you mean about “the trackingID can be sync with the other models together”?
