The proposed dual-perturbation optimization (DPO) method improves LiDAR-based 3D object detection performance by enhancing model generalizability and resilience to minor data variations. This is achieved through a combination of minimizing sharpness in the loss landscape, introducing adversarial perturbations to input BEV features, and utilizing reliable Hungarian matching and early cutoff techniques for trustworthy pseudo-labeling. Experimental results demonstrate that DPO outperforms previous state-of-the-art approaches on various transfer tasks, including Waymo → KITTI, with a significant 57.72% improvement in AP3D and reaching 91% of the fully supervised upper bound.
Low GrooveSquid.com (original content) Low Difficulty Summary
The researchers developed a new method to make LiDAR-based object detection work better in different conditions. They found that current methods don’t generalize well when the test data is different from the training data. To fix this, they created a way to make the model more adaptable by minimizing its sharpness and introducing noise into the input features. This helps the model perform better even with small changes in the test data. The new method was tested on three different tasks and performed significantly better than previous methods.
