ZED X / 2i questions

Hi there,

I’m rather n00b regarding computer vision and some clarifications might be pretty useful.

The application is an indoor mobile robot. For this case the preliminary winners are ZED X & 2i

ZED X
pros

  • GMSL2 connection it seems is the new trend
  • good image/depth quality
    cons
  • needs additional GMSL connection board
  • price (camera + connection board)

ZED 2i
pros

  • USB 3 connection that can be used on normal computers (Linux/Windows)
  • the depth scenery is pretty good
    cons
  • less resolution/FPS than X
  • no global shutter

1. I tend slightly to the ZED X because it seems more future proof. What’s your advice here?

2. For indoor applications with sun light and artificial light scenery the camera is best to be without polarizer?

3. The ZED will be connected to a Jetson NX 16GB. This hardware is sufficient for robot vision and ROS navigation/control tasks?

Thank you in advance!

Hi @Ktysai
Welcome to the Stereolabs community.

ZED X is designed for robotics with features that make it the perfect choice this type of applications.

We advise you to select the polarizer option only for outdoor applications under direct sunlight.

The ZED X can be used with both Jetson Xavier NX and Orin NX.
Orin models have improved performance, but Xavier NX is good for realtime control and navigation.

Thank you @Myzhar :grinning: :robot:

If I may pursue any further the polarizer issue:

  • for indoor only - NO polarizer recommended (my case)
  • for mixed operation indoor & outdoor (maybe I’ll reach this phase) still NO polarizer recommended?
  • outdoor mostly with direct sunlight - polarized recommended.

The capture card with GMSL2 connection how it is connected to the jetson modules?

In this case, the polarizer is recommended.

AGX and NX devkits have different configurations. You can get more information in the online documentation: Get Started with ZED X | Stereolabs

Thank you again for your help.

At that link, the AGX dev kits have description on how the capture card is connected (practically is a plug in)

The NX devkits do not have description, the link goes to ZED X main page.
After some digging the result was:

The capture card seems to be quite versatile :slight_smile:

Have a lovely day!

Yes, it is.

Please do not hesitate to ask for more information if you need it.

Zed box with Orin NX can be opened? If I do that I void warranty?

Btw, it has some CAN connector hidden?

No, you cannot open the ZED Box without voiding the warranty.

No, CAN bus is not available

Hi guys!

Just to be sure.
If I buy the ZED X and the ZED box. Look at the attachment, do I need extra cables for connection/power supply to buy from you?

Thanks!

No, you will receive all the required components to use the ZED X.

After many iterations it seems that I’ll get the ZED X & the capture card from Stereolabs.

In your tutorial for connecting the ZED X to an Jetson NX s MIPI cables are used.
From what I understand they have to be:

  • 15pin
  • opposite side
  • 1mm pitch
  • max 100mm

The normal cables for Raspberry PI … Camera can be used here?
In the tutorial 50mm cables are used, is advisable to really used 50mm length and not more?

In the tutorial in the picture only the capture card is powered, not the Jetson NX. It needs to be powered as well?

Thank you in advance!

The shorter the better to have a stable signal.

They must be both powered.
