Deepstream with stereo camera

[mztony314]

Hi, Thanks for the great work of deepstream in advance!
I built a deepstream pipeline with a normal usb camera before and it worked so well. And now i am going to change the camera to a stereo camera because i need to get the stereo information of the detection results.
My first question is that in my origin pipeline , I use python to the get the detection metadata in deepstream, if I want to get the stereo metadata, is it available in python or do i have to switch to c++?
My second question is that is Intel Realsense stereo camera the only option to get stereo information in deepstream? Or deepstream can support other stereo camera?
This is the first time i tried deepstream, so if my question is silly pls forgive me. Thank u in advance!

You can customize your stereo metadata. And we have open source the pyds python bindings. You can add your own python binding based on it.

No. We take the Intel Realsense camera as an example to show how to involve new data type into DeepStream. We even use the DS3D Interface to integrate Lidar data into DeepStream. Please investigate DS3D interfaces with the samples.

Thanks for your reply! I have one more question that does deepstream have any python example for ds3d interface?

Currently no. The pyds binding is open source. You can create the DS3D python bindings by yourself.

I read the DeepStream Python API Reference and cannot find anything related to stereo metadata, is there any reference that i can refer to ?

[Fiona.Chen]

There is no update from you for a period, assuming this is not an issue anymore. Hence we are closing this topic. If need further support, please open a new one. Thanks

Currently no DS3D related python binding is available. The pyds binding is open source. deepstream_python_apps/bindings at master · NVIDIA-AI-IOT/deepstream_python_apps (github.com) You can create the DS3D python bindings by yourself. Any python sample app can be the reference for how to construct DeepStream pipeline.
