GenZ-ICP introduces an innovative iterative Closest Point (ICP) method that enhances LiDAR-based pose estimation by adaptively integrating point-to-plane and point-to-point error metrics, ensuring robust performance across diverse and degenerative environments.
Key Highlights
- Adaptive Error Metric Integration – Combines point-to-plane and point-to-point error metrics, leveraging their complementary strengths for improved pose estimation accuracy.
- Planarity-Based Correspondence Classification – Utilizes Principal Component Analysis (PCA) to assess local surface variations, classifying correspondences as planar or non-planar to apply the appropriate error metric.
- Environment-Aware Weighting Mechanism – Introduces an adaptive weighting strategy that adjusts based on the ratio of planar to non-planar correspondences, enhancing adaptability to various environmental geometries.
- Degeneracy Resilience in Corridor-Like Scenarios – Demonstrates robustness in environments with degenerative structures, such as long corridors, by preventing ill-posed optimization problems.
- Experimental Validation Across Diverse Datasets – Exhibits performance on par with state-of-the-art LiDAR odometry methods in general environments and superior performance in degenerative scenarios.
- Open-Source Implementation Available – Provides a publicly accessible codebase for ROS1 and ROS2, facilitating adoption and further research in the robotics community.
