So the depth engine in depthai/OAK is limited to 1280 resolution width. It technical would be possible to decimate larger images into this resolution, and produce a depth map from these higher res sensors across the whole field of view, but it would technically still be 1280 actual horizontal resolution (instead of 1920 or 3840 horizontal pixels).
That said, it is likely possible to do such a decimation (to produce the entire image) and then fill this in with a tiled full resolution. That said, we have not implemented such a thing. It is likely possible with our Gen2 pipeline system, with the host involved for helping to shuffle tiles/etc. back/forth.
So TLDR, likely doable - but we haven't tried it. And definitely not just plug/play doable. I suspect 1080p could run at 30FPS. And I'd expect 4k would be something like 10FPS or so. But I don't know how much host load this would cause.
