Patchwork++: Fast and robust ground segmentation method for 3D LiDAR scans. @ IROS'22
Ground segmentation benchmark in SemanticKITTI dataset
Source code for the article "GroundGrid: LiDAR Point Cloud Ground Segmentation and Terrain Estimation"
Very early system focused on 3D physics platformer gameplay. Contains a raycast based ground detection system to get collider normal information, allowing forces to be scaled by the current ground angle.
