LiDAR Distillation: Bridging the Beam-Induced Domain Gap for 3D Object Detection. (arXiv:2203.14956v2 [cs.CV] UPDATED)

In this paper, we propose the LiDAR Distillation to bridge the domain gap
induced by different LiDAR beams for 3D object detection. In many real-world
applications, the LiDAR points used by mass-produced robots and vehicles
usually have fewer beams than that in large-scale public datasets. Moreover, as
the LiDARs are upgraded to other product models with different beam amount, it
becomes challenging to utilize the labeled data captured by previous versions'
high-resolution sensors. Despite the recent progress on domain adaptive …
