Low fps

Kristoffer

Hi!

We are using 3 cameras with YoloSpatialDetectionNetworks at 1080p and StereoDepth at 400P. When using YoloDetectionNetwork we were stuck at 15 fps and are told it is a limitation of Yolo. However, after also including "Spatial" we are now down to 7-10 fps without any other processing which is too low. What can we do to improve the fps? I am not sure what optimizations we can try that will result in a significant increase in fps.

Thanks!

Hi Kristoffer
1080p NN input is insanely large for edge devices such as the OAKs. Could you try first downsizing the input to something like 300x300 or 416x416..
Try using yolov6, since it has been empirically proven to run the fastest on MyriadX.

Thoughts?

Thanks,
Jaka

Sorry, my mistake. The NN is 640x640, not 1080p. The resolution of the RGB camera is 1080p however (we also tried at 720p without any noticeable difference).

Hi Kristoffer
Can you opt for a lower resolution input? 640 is still quite high to be run along with Stereo Depth.
Any particular reason you are using 640 - accuracy/precision?

Thanks,
