摘要:

在用于辅助和自动驾驶系统的各种传感器中,汽车雷达被认为是一种强大且低成本的解决方案,即使在恶劣的天气或照明条件下也是如此。随着雷达技术和开源标注数据集的发展,雷达信号的语义分割变得非常有前途。然而,现有的方法要么计算昂贵,要么通过平均将原始3D雷达信号减少到2D平面来丢弃大量有价值的信息。在这项工作中,我们介绍了ERASE网络,一个有效的雷达分割网络分割的原始雷达信号的语义。我们的方法的核心是新的检测,然后段方法的原始雷达信号。该方法首先检测出目标的中心点,然后提取出一个紧凑的雷达信号表示,最后进行语义分割。我们表明,我们的方法可以实现优越的性能雷达语义分割任务相比,国家的最先进的(SOTA)技术。此外,我们的方法需要少20倍的计算资源。最后,我们表明,所提出的ERASE网络可以压缩40%,而不会显着损失性能,显着超过SOTA网络,这使其成为一个更有前途的候选人,为实际的汽车应用。

英文摘要:

Among various sensors for assisted and autonomous driving systems, automotive radar has been considered as a robust and low-cost solution even in adverse weather or lighting conditions. With the recent development of radar technologies and open-sourced annotated data sets, semantic segmentation with radar signals has become very promising. However, existing methods are either computationally expensive or discard significant amounts of valuable information from raw 3D radar signals by reducing them to 2D planes via averaging. In this work, we introduce ERASE-Net, an Efficient RAdar SEgmentation Network to segment the raw radar signals semantically. The core of our approach is the novel detect-then-segment method for raw radar signals. It first detects the center point of each object, then extracts a compact radar signal representation, and finally performs semantic segmentation. We show that our method can achieve superior performance on radar semantic segmentation task compared to the state-of-the-art (SOTA) technique. Furthermore, our approach requires up to 20x less computational resources. Finally, we show that the proposed ERASE-Net can be compressed by 40% without significant loss in performance, significantly more than the SOTA network, which makes it a more promising candidate for practical automotive applications.
