Reviewing 3D Object Detectors in the Context of High-Resolution 3+1D Radar. (arXiv:2308.05478v1 [cs.RO])

Recent developments and the beginning market introduction of high-resolution
imaging 4D (3+1D) radar sensors have initialized deep learning-based radar
perception research. We investigate deep learning-based models operating on
radar point clouds for 3D object detection. 3D object detection on lidar point
cloud data is a mature area of 3D vision. Many different architectures have
been proposed, each with strengths and weaknesses. Due to similarities between
3D lidar point clouds and 3+1D radar point clouds, those existing 3D object
detectors are …
