3 years ago Hi @ProtossDragoon May I first confirm whether your alignment lag is occurring in the librealsense SDK or in ROS, as you have RViz in the background of your image. Thanks!

</launch>Thanks very much for the information. There has been a ROS / Jetson case to your one a week ago where, if pointcloud was enabled OR align_depth was enabled then it performed fine. But if both pointcloud AND align_depth were enabled in the same launch then it strongly lagged.
https://github.com/IntelRealSense/realsense-ros/issues/1995
That RealSense user confirmed the behavior on Jetson TX2, NX and AGX but found that the problem did not occur on an Intel NUC computer.
Can you confirm whether you are using a point cloud in ROS or not, please?
I note your mention of CMake. Did you install the SDK on your Jetson using the native backend method described in Intel's Jetson installation instructions?

3 years ago original case (no pointcloud, no align depth)
pointcloud only
align depth only
pointcloud AND align depth
CPU usage, latency and FPS drop was very high in all trials, except the first one.
Yes, maybe I installed native backend (./scripts/patch-realsense-ubuntu-L4T.sh, -DFORCE_RSUSB_BACKEND=false), not RSUSB backend.
Full install command for Realsense SDK in my case :

sudo make installI've been using mains-powered USB hub (one with an independent power supply) too.
On my Jetson env jsetson sdk 4.5.1 -> install ros -> install realsense sdk with cuda -> remove opencv4 -> install opencv4 with cuda -> install realsesne-ros (realsense2_camera) and now here. Do you recommend remove all of environment and reinstall everything?

3 years ago Sometimes a complete wipe and reinstall of the whole system (Ubuntu, ROS, RealSense ROS wrapper) can fix an installation where you have tried everything else and it still isn't working, because the total reinstallation can remove a hidden problem that you would not otherwise have found. It is just frustrating for something to be fixed without knowing what the cause was, as you cannot take account of it in future installations.

3 years ago Okay, I understood that could be more progress in my case, not from the current limitation of realsense SDK or realsesne2-camera ros package. I'll close this issue and try to reinstall my all system to solve this problem. Thank you very much for support @MartyG-RealSense ! Could I ask more information if there's no advance after that?

3 years ago Thanks very much @ProtossDragoon for the update - yes, you are welcome to post further questions. Good luck!
Issue Description
Hi, I'm using two realsense d435 devices in my project and I have noticed that the execution time of the rgb-depth alignment on Jetson Xavier AGX has very long latency (about 1.5~2 seconds latency exists between alignment processed result visualization and real-world happening), and pumping CPU a lot. While on the same machine, without rgb-d alignment code, it runs much faster, no latency. Given https://github.com/IntelRealSense/librealsense/pull/2670, maybe it's not optimal performance on my Jetson Xavier AGX.
+I already used "build with cuda" cmake flag.
Thanks!
