ROS node hangs when running #47

Closed FixedSpecialty closed 3 years ago

FixedSpecialty commented 3 years ago

I saw a similar issue and followed all the steps/read the articles Understanding ROS Topics and Introduction to Working With Laser Scanner Data. The issue I am having is that even after publishing the bag file to the filtered_cloud node,rosrun multi_object_tracking_lidar kf_tracker still hangs at About to setup callback. The bag file's topic publishes to /livox/lidar so I am "forwarding" it to /filtered_cloud.

I am running in separate terminals on Windows 10 in Ubuntu 18.04 LTS terminals: roscore rosrun multi_object_tracking_lidar kf_tracker - After running this it hangs on About to setup callback forever! rosbag play --clock /mnt/d/RosBags/demo2.bag /livox/lidar:=/filtered_cloud rosparam set use_sim_time true and rosrun tf static_transform_publisher 0 0 0 0 0 0 map dummy_frame 100

After all these commands, and publishing I am stuck on the About to setup callback message. Any help is greatly appreciated!

The image below shows my RVIZ setup as well. image

Delay was caused by a lack of processing power. When pausing the rosbag halfway through while everything is running. The kf_tracker would actually run around 2 minutes later.
