Trace invalid LiDAR coordinates through PCL cleanup, verify the is_dense flag, preserve point indices and test the actual finite-value filtering path.

Trace invalid LiDAR coordinates through PCL cleanup, verify the is_dense flag, preserve point indices and test the actual finite-value filtering path.

A fixed-scene procedure that separates point-cloud display persistence, scan batching and missing measurements.

3D point cloud processing pipeline practical guide with field checks, setup decisions and LidarStar sensor-selection notes.
