I am using USB3.0. I will buy a USB3.2 (superspeed) pci add on card to try and post the result.
This is the result running:
python3 .\depthai_demo.py -s left right -monor 400 -monof 120 -dnn -dd
It's still using 44MB/sec (using HDD Device Monitor Studio 8.36) which is still far less than typical USB3.0 transfer maximum speed 320MB/sec.
It seems OAK-D has not yet got too heavy loading on USB3.0 bus, but I will try USB3.2 to see the result.
We are replacing previous stereo cameras on our existing systems with OAK-Ds. And these existing PC we used Intel NUC which has no PCI socket to add and only with USB3.0 ports. If only with USB3.2 to get near 120fps, that means we have to use new NUC with USB3.2 to replace old USB3.0 NUCs.
So, that why I am checking can USB3.0 to get 120fps or not. And we do appreciate Luxonis can help us on this!
