Is NVidia Jetson AGX Xavier Ethernet interface able to support 3D Camera?

Hi,

I am thinking of using NVidia Jetson AGX Xavier for a robotics application. The Camera is a 3D Camera (data format very similar to as Intel RealSense Depth Camera D415 but the interface is Ethernet.

===========================================================
Max throughput for one camera with 2 streams :

・RGB 1280x720 @30 FPS

・Depth 1280x720 @30 FPS

RGB = 1280 x 720 x 30 x 16 bit = 442,368,000 bits

Depth = 1280 x 720 x 30 x 16 = 442,368,000 bits

Total max throughput for 1 camera with 2 streams = 884,736,000 bits

===========================================================

Question 1:
Will AGX Xavier Gigabit Ethernet interface be able to handle this throughput requirements?

Question 2:
Since I need to use 2 POE Cameras and since Xavier has only one ethernet interface, I was thinking of USB 3.1 to Ethernet bridge and cpnnecting another camera over there. Will USB 3.1 to Ethernet converted interface be able to handle this throughput requirements?

Hi,
The calculation for RGB seems to be wrong. It should be

RGB = 1280 x 720 x 30 x 24 bit

Ideal throughput of Ethernet is 1Gbps, but may not be able to achieve it in real environment. Ideal throughput of USB3 gen1 is 5Gbps. It would be better to use USB3 interface for this use-case.

Calculations are correct

It’s a special camera with 16 bits per pixel

If anyone tried to interface 3D camera that gives RGB and Depth streams per camera with AGX Xavier?

My bad…your are right

for RGB, it is RGB = 1280 x 720 x 30 x 24 bit
