RaLiFlow: Scene Flow Estimation with 4D Radar and LiDAR Point Clouds

arXiv — cs.CVFriday, December 12, 2025 at 5:00:00 AM
  • A new framework named RaLiFlow has been introduced for scene flow estimation by integrating 4D radar and LiDAR point clouds, addressing the lack of existing datasets that combine these modalities. This innovative approach aims to enhance the accuracy of scene flow estimation, particularly in challenging conditions where radar's robustness can be advantageous.
  • The development of RaLiFlow is significant as it leverages the strengths of both radar and LiDAR technologies, potentially leading to more reliable and cost-effective solutions for automotive applications, especially in autonomous driving and advanced driver-assistance systems.
  • This advancement reflects a growing trend in the field of artificial intelligence and autonomous systems, where multimodal data fusion is becoming increasingly important. The challenges of integrating different sensor types, such as noise and resolution issues, are being actively addressed, highlighting the ongoing evolution of technologies aimed at improving 3D object detection and scene understanding.
