Bi-Level Routing and Sparse Spatial Attention based Multi-View BEV 3D Object Detection for Autonomous Driving
An improved BEV 3D object detection algorithm Sparse-BEVNet is proposed, which introduces a Bi-Level Routing Attention mechanism into the image feature extraction network to reduce the computational burden of the backbone and employs Cascaded Group Attention in the feature fusion module.
