Is intel realsense D435i VL42 compliant??

[sj000]

I am trying to use the model trained with nvidia digits for object detection with a live feed. I am facing error. I heard only vl42 compliant devices work with jetson xavier(link to this post could be found below ).

Could you please let me know if this camera is vl42 compliant??

Thanks in advance

Hi sj000,

Thank you for your interest in the Intel RealSense D435i camera.

Linux build configuration is presently configured to use the V4L2 backend by default.

https://github.com/IntelRealSense/librealsense/blob/master/doc/installation.md#building-librealsense2-sdk

Be advised that Intel does not officially support the Jetson line of devices. Furthermore, there are several known issues with running librealsense on Jetson.

​@sj000​  I'd just like to add to this discussion that the JetsonHacks website has a guide to setting up the 400 Series cameras and Librealsense2 on Jetson AGX Xavier if you have not seen it already.

Thank you for the post. I followed Jetsonhacks article. However, on using the command,

v4l2-ctl --all

returns

So is it right that only the depth data is received and not rgb?? Also please have a look at my post at nvidia: https://devtalk.nvidia.com/default/topic/1048157/jetson-agx-xavier/issue-in-connecting-camera-/

Please provide me with some information on possibilities to get rgb data on v4l2.

Hello sj000, Could you please test the camera in Intel RealSense Viewer in order to determine is the RGB stream is working? Thank you and best regards, Eliza

Hello Eliza,

Thank you for your post. It works with ./realsense-viewer. However the output from v4L is as above. Any idea on why is that so?? and how to get an output in the v4L??

Hello sj000, Thank you for your reply! I found this thread that might be helpful to you: https://github.com/IntelRealSense/librealsense/issues/2682 Here an RealSense user managed to use D435 with Jetson + yavta. Hopefully this case help you! Thank you and best regards, Eliza

[sj000]

Hello Eliza,

Thank you for the link but the case is different. My doubt is if the device is v4l2 compliant, what is the reason that there is no ouput with the command v4l2-ctl --all??

Best regards
