Class-Distribution Guided Active Learning for 3D Occupancy Prediction in Autonomous Driving

RA-L 2026

3D occupancy prediction provides dense spatial understanding critical for safe autonomous driving. However, this task suffers from a severe class imbalance due to its volumetric representation, where safety-critical objects (bicycles, traffic cones, pedestrians) occupy minimal voxels compared to dom

CRAB: Camera-Radar Fusion for Reducing Depth Ambiguity in Backward Projection Based View Transformation

ICRA 2025

Recently, camera-radar fusion-based 3D object detection methods in bird's eye view (BEV) have gained attention due to the complementary characteristics and cost-effectiveness of these sensors. Previous approaches using forward projection struggle with sparse BEV feature generation, while those emplo
