  • 用全局Lipschitz优化框架替代传统梯度法,提升鲁棒性验证精度
  • 在旋转和对比度扰动下,成功识别出位置偏差超限的失效模式
  • 适用于关键点回归与深度检测,为感知系统认证提供实用路径

将自主系统部署于安全关键领域需确保对物理上合理的几何扰动具备鲁棒性,而非仅对抽象的像素级噪声。在视觉导航与自主着陆中,机器学习组件须在动态运行条件下(如相机旋转、光照变化)进行严格验证。尽管一阶空间攻击在分类任务中已失效,我们发现标准梯度启发式方法(如APGD)在姿态估计中同样失效,常表现劣于简单随机采样基线。为此,我们基于全局Lipschitz优化(GLO)重构姿态估计鲁棒性验证框架。该方法能有效定位全局最优解,并具备强理论收敛性。我们在YOLOv8-Pose关键点检测器与PnP求解器上评估该框架,针对旋转与对比度扰动,GLO成功识别出位置偏差超过安全操作阈值的关键失效模式,并使搜索空间缩减超80%。据我们所知,这是首个将几何鲁棒性验证扩展至连续关键点回归与深度目标检测的研究,为实现可信自主感知迈出实际一步。

原文摘要 · Abstract (English)

Deploying autonomous systems in safety-critical domains demands guaranteed robustness against physically plausible geometric perturbations rather than abstract pixel-wise noise. In vision-based navigation and autonomous landing, machine learning components require rigorous validation under dynamic operational conditions such as camera rotations and lighting shifts. Extending findings on the failure of first-order spatial attacks in classification, we show that standard gradient-based heuristics (e.g. APGD) similarly fail on for pose estimation, often performing worse than a simple random sampling baseline. To overcome these optimization bottlenecks, we reformulate pose estimation robustness within the framework of Global Lipschitzian Optimization (GLO). We argue that GLO offers a principled approach to robust validation, effectively localizing global optima with strong theoretical convergence guarantees. We evaluate this framework on a YOLOv8-Pose keypoint detector with a Perspective-n-Point (PnP) solver against rotation and contrast. In our evaluations, GLO successfully isolates critical failure modes where position deviations exceed safe operational limits, while rapidly pruning the search space by over 80%. To the best of our knowledge, this is the first study to extend geometric robustness validation to continuous keypoint regression and deep object detection, establishing a practical step toward certifying robust autonomous perception.
