[driver_nodelet-2] process has died

Hi, Thank you for the awesome work.

When I run your project, I encountered some errors. Please see the information below:

[driver_nodelet-2] process has died [pid 13061, exit code 255, cmd /opt/ros/noetic/lib/nodelet/nodelet velodyne2_nodelet_manager __name:=driver_nodelet __log:=/home/lk3696/.ros/log/16ed2878-26a1-11ec-834a-19b1195a40f3/driver_nodelet-2.log]. log file: /home/lk3696/.ros/log/16ed2878-26a1-11ec-834a-19b1195a40f3/driver_nodelet-2*.log [cloud_nodelet-3] process has died [pid 13062, exit code 255, cmd /opt/ros/noetic/lib/nodelet/nodelet velodyne_nodelet_manager __name:=cloud_nodelet __log:=/home/lk3696/.ros/log/16ed2878-26a1-11ec-834a-19b1195a40f3/cloud_nodelet-3.log]. log file: /home/lk3696/.ros/log/16ed2878-26a1-11ec-834a-19b1195a40f3/cloud_nodelet-3*.log

I use ubuntu 20.04 and I take real lidar (VLP-16) data. Additionally, I uncomment line 13~ 28 and change args="load velodyne_driver/DriverNodelet velodyne_nodelet_manager" to args="velodyne_nodelet_manager" in object3d_detector.launch.

Do you know how I can fix it? Any help is much appreciated!

Hi, for Noetic, try this:

<node pkg="nodelet" type="nodelet" name="velodyne_nodelet_manager" args="manager" output="screen"/>
  <include file="$(find velodyne_pointcloud)/launch/transform_nodelet.launch">
    <arg name="model" value="VLP16"/>
    <arg name="calibration" value="$(find velodyne_pointcloud)/params/VLP16db.yaml"/>
    <arg name="manager" value="velodyne_nodelet_manager" />
    <arg name="max_range" value="50"/>
    <arg name="min_range" value="0.4"/>
    <arg name="organize_cloud" value="false"/>
  </include>
