About this paper
Yuhan Zhou, Haihua Chen, Kewei Sha
Researchers at the University of North Texas propose a Multi-layer Task-centric and Data Quality Vase Framework for autonomous driving that systematically links data quality to task requirements. Their empirical evaluation demonstrated that intelligent removal of redundant data, both within multisource camera data and across image/LiDAR modalities, can maintain or improve object detection performance while enhancing system efficiency.
Key insights
- Redundancy is a prevalent data quality issue in both multisource (e.g., multiple cameras) and multimodal (e.g., camera and LiDAR) autonomous driving datasets.
- Intelligent removal of redundant data, guided by data quality metrics, can maintain or even improve object detection performance while enhancing system efficiency.
- Objects exhibiting high cross-modal redundancy are often located very close to the ego-vehicle, suggesting that for close-range objects, LiDAR and camera data frequently provide overlapping information.
