SPIRAL: Semantic-Aware Progressive LiDAR Scene Generation and Understanding

arXiv — cs.CV•Tuesday, November 4, 2025 at 5:00:00 AM

A recent advancement in LiDAR technology has led to the development of SPIRAL, a method that enhances 3D scene generation by integrating semantic awareness. This innovation addresses the limitations of previous range-view methods, which often produced unlabeled scenes. By leveraging diffusion models, SPIRAL not only generates geometric structures but also accurately predicts semantic labels, improving cross-modal consistency. This is significant as it opens new avenues for applications in autonomous driving, robotics, and urban planning, making 3D scene understanding more efficient and reliable.
