I am using an Auto Focus IMX582 camera with a sensor resolution of 5312x6000. The problem I am facing is that it takes too long to focus and return the lens value. Additionally, I have six PoE cameras connected. When I switch the sensor to 4K, which is the default resolution, the focusing of all six cameras is quick. I use the focus value for fixed focus to capture images at three different exposures for HDR merging.

How to get auto focus value, so we can put that value manually everytime camera starts?

I dont want to run any inference on it , can setting video size to lower resolution can help in acheiving 4k 30 fps? I just want to record video without running any inference but max resolution possible. Thoughts?

How to record 4k-30fps raw video and save the video from multiple Oak device connected to one host.

On Poe I get around 20-22 fps while on USB-C I get around 38 fps.

My poe_test.py gives following output:

mxid: 14442C1061D2EBCF00 (OK)

speed: 1000 (OK)

full duplex: 1 (OK)

boot mode: 3 (OK)

Oak bandwidth test- Downlink 874.1 mbps

Uplink 278.0 mbps

I get more fps on Oak-1usb and less fps on Oak-1 POE.

Thoughts?

@leeor make sure you are using 3.0 speed high speed USB cable, this is something I had overlooked which resulted in lower fps. Also another thing to keep in mind is the number of Shave while converting model to .blob. 6 shave gave me 15 fps while 5Shave gave me 25 fps while running inference. Hope this helps!

I am using YOLO tiny with 300 x 300 preview size. Is there any way to get high quality crop image of detection?
