frame rate while using TPU? #4

Closed GOBish closed 4 years ago

GOBish commented 4 years ago

When using the edgeTPU (-tpu option) and -display option, I am getting frame rates of only 1 FPS or so. Is this expected? I would have expected better performance.

Thanks!

Yes, that sounds about right. If you drop the -display flag it should reach ~10fps on an rpi.

That is interesting -- I would have expected a higher frame rate with RPi 4 (4gb) + Coral EdgeTPU. Using a mobilenet model I get >30fps with object detection and my experiments with SORT in the past have not significantly slowed that.
