Cropping of 48MP @ 430 FPS?

SamiUddin231996

How many FPS of OAK4 on Full Resolution 48MP?

Does OAK4 has on-device cropping engine?

How much FPS we get if we crop a bbox ROI from a Full Resolution 480MP in ?

How many Neural Networks can we Run on OAK4 in parallel and Real-time.

Hey SamiUddin231996 - OAK4 supports full 48MP (8000x6000) on the IMX586, and the we support that mode at up to 18 FPS.

Yes, OAK4 supports on-device cropping / ROI. You can crop on-device with the camera output path and with ImageManip.

If you crop a bbox ROI from a 48MP stream, that does not automatically increase the camera FPS. If the source is still in 48MP mode, the ROI is still coming from that 48MP source mode. Cropping helps reduce downstream bandwidth and NN workload, but not sensor readout FPS.

If you need high FPS, use lower native IMX586 modes instead. Check them out at the link I posted.

For AI, OAK4 can run multiple neural networks concurrently, but there is no single fixed “max number” for real-time use. It depends on the exact models, resolutions, and target FPS, so the right answer is to benchmark the intended model combination.

Thanks,

OskarSonc i need to achieve 4000x3000 at 60FPS, how can I do that? as your team mentioned in above docs link.

OskarSonc I need the code please for 4000x3000 at 60FPS (NO HDR)

SamiUddin231996 - 4000x3000 @ 60 FPS on OAK4 is supported on the IMX586 in non-HDR 2x2 binning mode.

In DepthAI v3, the way to request it is:

cam = pipeline.create(dai.node.Camera).build(
    dai.CameraBoardSocket.CAM_A,
    (4000, 3000),
    60
)
out = cam.requestOutput((4000, 3000), fps=60)

One note: this requests the 4000x3000 @ 60 sensor mode on-device. If you then stream all full-resolution frames to the host, the host link / display / storage path can still become the bottleneck. If you need to send that stream out efficiently, use on-device video encoding (VideoEncoder), for example H.264, H.265, or MJPEG.

Thanks,

Thanks a lot 🙂 Solved.
