提升自动驾驶3D占位预测的不确定性估计效率,增强恶劣条件下的系统鲁棒性。

OCCUQ: Exploring Efficient Uncertainty Quantification for 3D Occupancy Prediction

  • 基于认知不确定性动态校准模型置信度,实现高效不确定性量化。
  • 在雾天、摄像头缺失等场景下,对未知数据的不确定性评分更高,提升异常检测能力。
  • 适用于自动驾驶系统在真实复杂环境中的可靠性评估,尤其适合安全关键场景。

自动驾驶有望显著提升生产效率并带来诸多社会益处。确保这类安全关键系统在恶劣天气和传感器故障等未见条件下仍具鲁棒性至关重要。现有方法常忽略对抗性条件或分布外变化带来的不确定性,限制了其实际应用。本文提出一种针对3D占位预测的高效不确定性估计适配方法,通过认知不确定性估计动态校准模型置信度。在多种相机退化场景(如雾天、单摄像头失效)下验证,该方法能有效识别分布外数据,对未见样本赋予更高不确定性值。引入区域特异性退化模拟单摄像头缺陷,并通过场景级与区域级评估验证有效性。结果表明,相比深度集成与MC-Dropout等基线方法,本方法在分布外检测与置信度校准方面表现更优。该方法始终提供可靠不确定性度量,具备提升自动驾驶系统真实场景鲁棒性的潜力。代码与数据集见:https://github.com/ika-rwth-aachen/OCCUQ。

原文摘要 · Abstract (English)

Autonomous driving has the potential to significantly enhance productivity and provide numerous societal benefits. Ensuring robustness in these safety-critical systems is essential, particularly when vehicles must navigate adverse weather conditions and sensor corruptions that may not have been encountered during training. Current methods often overlook uncertainties arising from adversarial conditions or distributional shifts, limiting their real-world applicability. We propose an efficient adaptation of an uncertainty estimation technique for 3D occupancy prediction. Our method dynamically calibrates model confidence using epistemic uncertainty estimates. Our evaluation under various camera corruption scenarios, such as fog or missing cameras, demonstrates that our approach effectively quantifies epistemic uncertainty by assigning higher uncertainty values to unseen data. We introduce region-specific corruptions to simulate defects affecting only a single camera and validate our findings through both scene-level and region-level assessments. Our results show superior performance in Out-of-Distribution (OoD) detection and confidence calibration compared to common baselines such as Deep Ensembles and MC-Dropout. Our approach consistently demonstrates reliable uncertainty measures, indicating its potential for enhancing the robustness of autonomous driving systems in real-world scenarios.
