Lidar RSSI Value Filter Suggestion #398

Closed KenYangSickTW closed 1 month ago

KenYangSickTW commented 1 month ago

Dear support team,

I hope this message finds you well.

I have a question regarding the ROS driver provided on GitHub. There is a parameter called "min intensity" used for filtering data.

Could you provide a recommended value for this "min intensity" parameter?

BR,

Ken

Thank you for your feedback. Intensity values are highly dependent on your lidar and the objects in the scene, especially the reflectivity of the observed objects.

To find a value for a filter using the "min_intensity" parameter, you can interactively set the min and max intensity options in rviz to a specific range and see the effect on the point cloud. The following screenshots show an example for TiM-781 with min intensity 0 (default) and min intensity 15000:
