摘要:

用于自动驾驶的人工智能必须满足对安全性和鲁棒性的严格要求,这促使对学习模型进行彻底验证。然而,目前的验证方法大多需要地面实况数据,因此既成本密集,适用性也有限。我们建议克服这些局限性的模型不可知验证使用先验知识从街道地图。特别是,我们将展示如何验证语义分割面具,并证明我们的方法使用OpenStreetMap的潜力。我们引入验证指标,表明假阳性或阴性路段。除了验证方法,我们提出了一种方法来纠正车辆的GPS位置,使一个更准确的定位可以用于基于街道地图的验证。最后,我们在Cityscapes数据集上给出了定量结果,表明我们的验证方法确实可以发现语义分割掩码中的错误。

英文摘要:

Artificial intelligence for autonomous driving must meet strict requirements on safety and robustness, which motivates the thorough validation of learned models. However, current validation approaches mostly require ground truth data and are thus both cost-intensive and limited in their applicability. We propose to overcome these limitations by a model agnostic validation using a-priori knowledge from street maps. In particular, we show how to validate semantic segmentation masks and demonstrate the potential of our approach using OpenStreetMap. We introduce validation metrics that indicate false positive or negative road segments. Besides the validation approach, we present a method to correct the vehicle's GPS position so that a more accurate localization can be used for the street-map based validation. Lastly, we present quantitative results on the Cityscapes dataset indicating that our validation approach can indeed uncover errors in semantic segmentation masks.
