Depth performance for specular/reflective/transparent materials

atjx

Hi, curious how is OAK's depth performance for specular materials (metals, reflective objects), transparent material (bottles), or saturated/occluded scenes and objects? Are there any examples you can share?

Thanks

Hey atjx I forwarded this to the team and will get back to you as soon as I get a result back.
Thanks for the wait.

Hey @atjx - I was able to get these:

Hope this helps,

atjx

thank you, this is very helpful

would it be possible to crop to this center region of the bin and re-scale the color map? I'd like to understand how good the depth map is around the objects inside the bin

atjx I managed to get these:

Note:
With this colorization, you can see that RVC4 neural stereo has a sort of fog in the background - this is a disadvantage of Neural Stereo: small objects have a tendency to sometimes blur into the background, which is itself a bit wavy. Neural stereo is however more accurate overall and definitely has a higher fillrate (less missing pixels) compared to traditional stereo.

I also have more different zoomed in similar compositions if you would like...
