Researchers have developed DeGuNet, a new ultra-compact image backbone designed to improve the efficiency and accuracy of 3D object detection in autonomous driving systems. This plug-and-play module integrates LiDAR and camera data more effectively by incorporating sparsity-aware feature extraction, which aligns multi-view images with LiDAR depth data while preventing invalid region contamination. Experiments on the nuScenes dataset show that DeGuNet can significantly reduce GPU memory usage by up to 66.5% and speed up inference by 1.16x, while simultaneously improving detection accuracy by up to 6.20 absolute mAP.
