Towards Compact Autonomous Driving Perception with Balanced Learning and Multi-sensor Fusion
Summary
A novel compact deep multi-task learning model is introduced for autonomous driving perception, capable of handling multiple tasks in a single forward pass. This model simultaneously performs semantic segmentation, depth estimation, LiDAR segmentation, and bird's eye view projection. It incorporates an adaptive loss weighting algorithm to address imbalanced learning issues arising from numerous tasks. Through data pre-processing and intermediate sensor fusion techniques, the model integrates input modalities from RGB cameras, dynamic vision sensors (DVS), and LiDAR sensors positioned on the ego vehicle, enhancing environmental understanding. Ablation and comparative studies demonstrate that the proposed method achieves superior performance with significantly fewer parameters, enabling faster inference and reduced GPU memory utilization. The model's consistency is validated across three CARLA simulation datasets and one real-world nuScenes-lidarseg dataset.
Key takeaway
For Machine Learning Engineers developing autonomous driving perception systems, this research offers a path to significantly reduce computational overhead. You should consider integrating compact multi-task learning models that leverage adaptive loss weighting and intermediate multi-sensor fusion. This approach allows for faster inference and lower GPU memory usage, crucial for deploying robust perception capabilities on resource-constrained edge devices in real-world scenarios.
