Lidar Preprocessing Technique

1. DownSampling / Outlier Removal / Noise Filtering
   • Find the data that are close to the ground level. To accomplish this, you would be ablel to find which lidar beam index points to the ground level
   • Remove the intensity value depending on the problems (mean filter / adaptive threshold)

Segment the Point Cloud Data

1. Use a clustring algorithm such as DBSCAN (Density Based Spatial Clustering of Application with )
