P2d-DO: Degeneracy Optimization for LiDAR SLAM With Point-to-Distribution Detection Factors

RA-L 2025

Although the LiDAR SLAM technique has been already widely deployed on various robots, it may still suffers from degeneracy caused by inadequate constraints in scenes with sparse geometric features. If the degeneracy is not detected and properly processed, the accuracy of localization and mapping wil

A Point-to-distribution Degeneracy Detection Factor for LiDAR SLAM using Local Geometric Models

ICRA 2024poster

Limited by the working principles, LiDAR-SLAM systems suffer from the degeneration phenomenon in environments such as long corridors and tunnels, due to the lack of sufficient geometric features for frame-to-frame matching. The accuracy and sensitivity of existing degeneracy detection methods need t…
