Centrala begrepp
The authors propose a novel Sparse Query-Centric paradigm for end-to-end Autonomous Driving (SparseAD), where the sparse queries completely represent the whole driving scenario across space, time and tasks without any dense BEV representation, enabling efficient extension to more modalities and tasks.
Sammanfattning
The authors propose a novel Sparse Query-Centric paradigm for end-to-end Autonomous Driving (SparseAD) to address the limitations of previous dense BEV-Centric end-to-end methods.
In the Sparse Perception module, perception tasks including detection, tracking and online mapping are unified in a sparse manner, where multi-sensor features and historical memories are regarded as tokens, and object queries and map queries represent obstacles and road elements respectively. This avoids the heavy computational and memory burden of dense BEV representations.
In the Motion Planner, with sparse perception queries as environmental representation, the authors apply multi-modal motion prediction for both ego-vehicle and surrounding agents simultaneously, and fully consider driving constraints of multiple dimensions to generate the final planning.
Experiments on the nuScenes dataset show that SparseAD achieves state-of-the-art full-task performance among end-to-end methods and significantly narrows the gap between end-to-end paradigms and single-task methods, demonstrating the great potential of the sparse query-centric paradigm.
Statistik
The proposed SparseAD method achieves 47.5% mAP, 57.8% NDS, 53% AMOTA, 60.8% Recall on 3D detection and tracking tasks.
For online mapping, SparseAD obtains 34.2% mAP, outperforming previous dense BEV-based methods.
In motion prediction, SparseAD achieves 0.83m minADE, 1.58m minFDE, 18.7% Miss Rate, 0.308 EPA, significantly outperforming previous end-to-end methods.
For planning, SparseAD attains the lowest average L2 error of 0.35m and Collision Rate of 0.09% compared to other end-to-end methods.
