Continuing the discussion from Different trackID between PGIE (car detector) and SGIE (plate detector):
• Hardware Platform GeForce RTX 2080 Ti
• DeepStream Version 6.2
• NVIDIA GPU Driver Version 470.63.01
• CUDA Version 10.2
• Issue Type questions
Here is a question from a topic:Different trackID between PGIE (car detector) and SGIE (plate detector) - #3 by Fiona.Chen
Like the case in this topic, how can i know the car plate belong to which car?

For the object meta of the SGIE, the “parent” is its object meta of the PGIE.
