30 fps object detection on OAK-D Lite?

msharad19

I'm currently able to perform object detection at 10fps using MobileNet SSD blob on OAK-D Lite.
I wanted to know if I've reached the best possible inference speed. Is it possible to go beyond 10fps for object detection?

Hello msharad19 ,
You should be able to achieve +30FPS with MobileNet on any OAK camera. I assume you are getting USB2 speeds which would limit the FPS. Could you try running depthai_demo and copying the terminal log?
Thanks, Erik

Hi Erik!
Thanks for your reply.
As suggested, I ran the following command-
python depthai_demo.py -cnn mobilenet-ssd
Attached is my current log. Does "low USB speed" in the log mean that I need to change something?
I see the following in the GUI for mobilenetSSD-
Color FPS - 16.6
NN FPS - 5.7

Hi msharad19 ,
Yes, you should be using (working) USB3 cable to get the SUPER speed, which should also improve the FPS for both the color and NN.
Thanks, Erik
