Abstract:

Sharing information between connected and autonomous vehicles (CAVs) fundamentally improves the performance of collaborative object detection for self-driving. However, CAVs still have uncertainties on object detection due to practical challenges, which will affect the later modules in self-driving such as planning and control. Hence, uncertainty quantification is crucial for safety-critical systems such as CAVs. Our work is the first to estimate the uncertainty of collaborative object detection. We propose a novel uncertainty quantification method, called Double-M Quantification, which tailors a moving block bootstrap (MBB) algorithm with direct modeling of the multivariant Gaussian distribution of each corner of the bounding box. Our method captures both the epistemic uncertainty and aleatoric uncertainty with one inference based on the offline Double-M training process. And it can be used with different collaborative object detectors. Through experiments on the comprehensive CAVs collaborative perception dataset, we show that our Double-M method achieves up to 4.09 times improvement on uncertainty score and up to 3.13% accuracy improvement, compared with the state-of-the-art uncertainty quantification. The results also validate that sharing information between CAVs is beneficial for the system in both improving accuracy and reducing uncertainty.
