Hi, I install rtabmap from source and build rtabmap_ros with noetic-devel version, then I try to experiment as demo(Robot mapping, ), the following error happens,

[points_xyzrgb-3] process has died [pid 100295, exit code 255, cmd /opt/ros/noetic/lib/nodelet/nodelet standalone rtabmap_util/point_cloud_xyzrgb rgb/image:=/data_throttled_image depth/image:=/data_throttled_image_depth rgb/camera_info:=/data_throttled_camera_info cloud:=voxel_cloud __name:=points_xyzrgb __log:=/home/lantuo/.ros/log/4b25d6e8-b3e8-11f0-9756-6b46d1322034/points_xyzrgb-3.log].

Do you have a local opencv version installed different than the system one? To debug more this kind of error, show backtrace of gdb, see Section A of this comment: https://github.com/introlab/rtabmap_ros/issues/28#issue-99654759
