Hole in center of depth map

izumi

Thank you for sharing current situation. Let me ask two more questions.

Can you share any plan with us for improving this issue?
Is the new project insufficient even for the short range of OAK-D-SR-POE?

I think this could be a risk for choosing OAK-D-PRO series instead of Realsense. Because they seems not to have this issue. (Of course they also don't have many features.)

Hi izumi ,
I apologize for the delay, I had to double-check with the team about it.

We are still working on a better dot projector, we have since gone through 2 revisions (that weren't an improvement). I believe the current ETA is end of Q4 for the (new revision of) new projector, we will soon receive initial samples.
It should be sufficient, as the pattern would be more random. It might also be that the current projector is sufficient (from eg. 25cm onwards), but we haven't tested it yet. Thoughts?

Hi erik ,

Thank you for sharing updates. Can you share the progress of the projector upgrading?

erik

Hi @izumi ,
We have received multiple different projectors (from different vendors), but none were significantly better. We are still in the process of evaluating different ones.

Hi @erik ,

Sorry for asking again. But can you share the progress about this issue?

erik

Hi @izumi ,
We will likely be implementing new projects to our RVC4-based cameras first (which is the main priority), and then update the design for current OAK cameras.

erik Does this improvement resolve this Hole in center of depth map issue?

erik

Hi @izumi ,
Likely no, as that issue isn't due to calibration, but dot projector pattern.

izumi

Hi erik ,

Is there any update about ETA for RVC4-based cameras?

Hi @izumi
Autumn 2024.

Hi jakaskerl ,

Thank you for your quick response! That is a little bit sad news to me because this articles said 2024 June was original plan. I'll wait next gen camera!

Hi @jakaskerl ,
I'm very interested in improvement of depth reliability on OAK4-D Pro. While waiting for it, can we expect any improvement on this topic with OAK-D Pro?
Because this issue is very critical for my application…

OAK4-D pro is fitted with a different dot projector (Himax), so this shouldn't be a problem here.

Thanks,
