摘要:

对于自动驾驶来说,雷达是一种重要的传感器类型。一方面,雷达提供了对环境中目标径向速度的直接测量。另一方面,在文献中,雷达传感器因其对几种不利天气条件的鲁棒性而闻名。然而,不利的一面是,雷达容易受到鬼目标或杂波的影响,这可能是由几种不同的原因造成的,例如,环境中的反射表面。例如,幽灵目标可能导致错误的目标检测。为此,需要在雷达数据中尽可能早地识别异常目标。在这项工作中,我们提出了一种基于PointNets的方法来检测异常雷达目标。修改PointNet架构驱动我们的任务,我们开发了一种新的分组变量,有助于多形式的分组模块。我们的方法在城市场景中的真实数据集上进行了评估,并显示出对异常雷达目标检测的良好结果。

英文摘要:

For autonomous driving, radar is an important sensor type. On the one hand, radar offers a direct measurement of the radial velocity of targets in the environment. On the other hand, in literature, radar sensors are known for their robustness against several kinds of adverse weather conditions. However, on the downside, radar is susceptible to ghost targets or clutter which can be caused by several different causes, e.g., reflective surfaces in the environment. Ghost targets, for instance, can result in erroneous object detections. To this end, it is desirable to identify anomalous targets as early as possible in radar data. In this work, we present an approach based on PointNets to detect anomalous radar targets. Modifying the PointNet-architecture driven by our task, we developed a novel grouping variant which contributes to a multi-form grouping module. Our method is evaluated on a real-world dataset in urban scenarios and shows promising results for the detection of anomalous radar targets.
