Abstract:3D object detection using point clouds has attracted increasing attention due to its wide applications in autonomous driving and robotics. However, most existing studies focus on single point cloud frames without harnessing the temporal information in point cloud sequences. In this paper, we design TransPillars, a novel transformerbased feature aggregation technique that exploits temporal features of consecutive point cloud frames for multiframe 3D object detection. TransPillars aggregates spatialtemporal poin… Show more
