Summary

• What is new: Introduces OccFusion, a new multi-modal fusion method that avoids traditional depth estimation for 3D occupancy predictions, alongside a novel point cloud sampling algorithm and active training methods.
• Why this is important: Existing fusion-based 3D occupancy prediction methods rely on depth estimation, which is an ill-posed problem and demands high computational resources.
• What the research proposes: OccFusion uses a multi-modal fusion approach without depth estimation and an active training method for efficient and accurate occupancy predictions.
• Results: Achieves higher IoU scores across all categories in the OpenOccupancy benchmark, surpassing state-of-the-art methods and requiring less computational resources for training and inference.
