Aligned_depth_to_color frame drop (to ~1 HZ) after upgrading firmware from 2.30 to 2.31 #1024
Comments
As for now, I am not aware of any performance difference between the versions. Will keep watching. |
Thanks for the reply. I build everything from the source and cmake with the "CMAKE_BUILD_TYPE=release" flag enabled. After re-install everything, the PC works good now, but the NUC still show similar results. rostoptic hz /camera/aligned_depth_to_color/image_raw remain low frequency (1~5 HZ). The NUC is installed in ubuntu 18.04 with kernal 5.0.0-37-generic. The NUC model is 5i7RYH. Is this behavior caused by the computer? |
I can confirm the same behaviour on my machine. For me a downgrade to librealsense 2.30 and recompiling the ROS driver with that version did the trick. Seems to be a bug in librealsense. |
Can you confirm this downgrade in performance using any of the librealsense tools? |
I am having the same issue with 2.32.1. My kernel version is 5.3.0-7625-generic running on Ubuntu 18.04 and I'm using pre-build packages. Does anyone know how to downgrade librealsense to 2.30 with apt-get? |
#5751 seems to fix the issue for me on Ubuntu 18.04, kernel 4.15.0-74-generic |
@armandok Did you try IntelRealSense/librealsense#5751 to see if it can fix your issue? Looking forward to your update. Thanks! |
@armandok Any update from your side? Thanks! |
@RealSenseCustomerSupport Yup. Tried it and fixed the problem! Thanks! |
@armandok Glad to hear that. Thanks for the feedback! |
After upgrading the librealsense firmware to 2.31. I notice the topic /camera/aligned_depth_to_color become really unstable.
I set depth rate as 15HZ.
In 2.30, I can consistently receive 14~15 HZ messages when call rostopic hz /camera/aligned_depth_to_color/image_raw
After upgrading to 2.31, I call the same topic but often receive "no new message" or topic between 1~6 HZ. It is very hard to receive the 15 HZ anymore.
I tried it both on a PC workstation and a NUC using two different D435i cameras. I believe it is not the problem frin the computer and the camera side.
Any comment is appreciate
