Abstract（TL DR）
EFFOcc explores towards the minimal (minimal computation costs and minimal label costs) baseline for fast and high-performance 3D occupancy prediction with lidar-camera fusion. We show with proper detection pretraining, lightweight BEV-based fusion occnet can perform as well as voxel-based fusion occnets. Then, We conduct activate learning with maximum entropy on frame- and voxel-level to see the minimum label requirements for occupancy prediction.
