latency in stereodepth map OAK-D Pro W PoE

Suryakant

We are using OAK-D Pro W PoE camera. We are using it for stereo depth measurement. The configuration that we are using is mentioned below:
SensorResolution 400P
StereoDepth.PresetMode.High_Density
MedianFilter.Kernal_5X5
LRcheck True
extended_disparity False
Subpixel False

For stereo depth we are getting 1-2 second latency with around 30 FPS. Can you please help us in reducing the latency. We need it for real time application.

Hi Suryakant ,
Have you checked https://docs.luxonis.com/projects/api/en/latest/tutorials/low-latency/#poe-latency ? If so, what are the outputs of these tests?
Thanks, Erik

Yes, i have tested for this all things are okay. For video capturing there is no latency in the output but when i am using the stereo-depth function only them i am facing the issue of latency.

Suryakant What's the total bandwidth used for streaming stereo-depth? Does it exceed the GigE link?
Thanks, Erik

Downlink 889.6 mbps
uplink 187.0 mbps

Hi Suryakant ,
Could you go through all the tests here: https://docs.luxonis.com/projects/api/en/latest/tutorials/low-latency/#poe-latency and provide feedback? Also, what's the total bandwidth used of the pipeline (not the downlink/uplink)? In other words, what streams are you streaming from cam to host, and what's the required bandwidth for all these streams?
Thanks, Erik
