Point Cloud Change Detection Based on ROI Similarity

Laser point cloud change detection is susceptible to spatial–structural uncertainties induced by residual registration errors, uneven point cloud density, viewpoint shift and object occlusion, which frequently produce numerous false alarms of spurious changes. To address this issue, this paper proposes an ROI-level 3D...

KPS: The Key Plane Structure for loop closure detection in indoor LiDAR SLAM

This paper proposes a loop closure detection method based on Key Plane Structures (KPS), which exploits the geometric stability of indoor plane structures to construct invariant global descriptors and provides more reliable loop closure constraints for pose graph optimization.
