Hello, I am using ROS for obtaining point cloud using IWR6843ISK. The package used is ( I tried to save the /ti_mmwave/radar_scan as pcd file but there was an error. Then I saved the point cloud data as bag file. I used bag_pcd to convert bag file to pcd. But the error displayed was,

Provided topic '/ti_mmwave/radar_scan' is in the bag file, but is not of type sensor_msgs/PointCloud2 (type: ti_mmwave_rospkg/RadarScan)
Could not find a sensor_msgs/PointCloud2 type on topic '/ti_mmwave/radar_scan' in bag file 2021-05-24-16-26-06.bag
Topics found in the bag file:
    /ti_mmwave/radar_scan (ti_mmwave_rospkg/RadarScan)

How to resolve this? Thanks in advance. Thanks and regards, Aleena N A

Looks like the /radar_scan topic is of type /RadarScan. The bag_to_pcd package requires sensor_msgs/PointCloud2 type.

You will have to find a way to convert RadarScan to PointCloud2 type and it should work fine.
