Three-Attention Mechanisms for One-Stage 3D Object Detection Based on LiDAR and Camera

This article studies one-stage 3-D object detection based on light detection and ranging (LiDAR) point clouds and red-green-blue (RGB) images that aims to boost 3-D object detection accuracy based on three attention mechanisms. Currently, most of the previous works converted LiDAR point clouds into bird's-eye-view (BEV) images, achieving a significant performance. However, they still have a proble...
