A deep learning method for online LiDAR-based 3D Moving Object Segmentation integrates a dual-branch network for spatio-temporal feature fusion with a coarse-to-fine 3D refinement module. The approach achieved a 70.16% IoU on the SemanticKITTI-MOS hidden test set, outperforming prior methods while operating at real-time speeds of 85.25 ms per scan.

Key insights

  • Dedicated branches for spatial appearance and temporal motion, combined with attention mechanisms, enable more effective spatio-temporal information fusion than simple concatenation.
  • Leveraging both 2D range image efficiency and 3D point cloud geometry through a coarse-to-fine refinement module significantly mitigates boundary-blurring artifacts.
  • Augmenting training data with manually refined labels from diverse environments improves the generalization and robustness of MOS models.
