How Depthai hardware is different than intel real sense #24

Closed yashhema closed 3 years ago

yashhema commented 3 years ago

Hello, I got to know of luxonis products yesterday while searching for depth camera, I saw real sense then I saw luxonis.

Can you please elaborate - how these products are different (intel realsense d4xx series + movidius)

Hi @yashhema ,

Great question. So we actually have a forum post that describes the differences. In short you nailed it though, DepthAI is effectively an Intel RealSense d4xxx series + Myriad X in a tightly-integrated product.

This figure mostly captures it: image

Here're more details though:

  1. Contrasting DepthAI with existing depth cameras: https://discuss.luxonis.com/d/48-summary-of-stereo-mapping-cameras
  2. How DepthAI allows integration into actual products (and modalities of doing so): https://docs.luxonis.com/faq/#how-do-i-integrate-depthai-into-our-product

Does that help?

Thanks, Brandon

Hello, Thanks for the answer. What about the distance range , like D435 can calculate depth till distance of 10 m , and D455 till almost 20 meters. And does the depth measurement , changes between day and night (ie it reduces in night as compared to day)

Sorry I was delayed on this one. I thought I had answered but apparently not. So we haven't done a whole lot of characterization of depth distance yet. But we support variable stereo baseline which makes it so long-range is feasible.

We are currently passive entirely. But ArduCam is making camera modules that allow active illumination like the BELICE-SD (here) and overall IR flood illumination (here)

So this would allow zero-light performance. For longer-distance more focused optics (implementable with M12, see here) and illumination may be of interest. Or just higher-brightness IR illlumination.

Thoughts?

Thanks, Brandon

Going to close this @yashhema for now but feel free to re-open it. But to leave with an image, we just got subpixel (https://github.com/luxonis/depthai/issues/163) running. Here's a view without any filtering. (Note that distanced greater than 2 meters were thrown away by the Open3D visualization, that's why you don't see behind me in the point cloud... it's just a setting in Open3D visualization I forgot to change.)

We'll be adding Bilateral filtering onboard as well (i.e. without any need for the host to do anything).
