论文摘要

该车辆重新识别(REID)在自动驾驶感知系统中起着至关重要的作用,近年来,这引起了越来越多的关注。但是,据我们所知,对于安装在车辆上的环境视图系统没有现有的完整解决方案。在本文中,我们在上述方案中提出了两个主要挑战:i)在单个相机视图中,由于鱼眼变形,遮挡,截断等,从过去的图像框架中识别出同一辆车辆很难识别同一车辆。II)在多相机视图中,同一车辆的外观从不同的相机的视图中差异很大。因此,我们提出了一个不可或缺的车辆重新ID解决方案,以解决这些问题。具体而言,我们提出了一种新颖的质量评估机制,以平衡跟踪框漂移和目标一致性的效果。此外,我们根据注意机制利用了重新ID网络,然后将其与空间约束策略相结合,以进一步提高不同摄像机之间的性能。实验表明,我们的解决方案在实践中实时实现了最先进的准确性。此外,我们将发布代码和带注释的Fisheye数据集,以使社区受益。

The vehicle re-identification (ReID) plays a critical role in the perception system of autonomous driving, which attracts more and more attention in recent years. However, to our best knowledge, there is no existing complete solution for the surround-view system mounted on the vehicle. In this paper, we argue two main challenges in above scenario: i) In single camera view, it is difficult to recognize the same vehicle from the past image frames due to the fisheye distortion, occlusion, truncation, etc. ii) In multi-camera view, the appearance of the same vehicle varies greatly from different camera's viewpoints. Thus, we present an integral vehicle Re-ID solution to address these problems. Specifically, we propose a novel quality evaluation mechanism to balance the effect of tracking box's drift and target's consistency. Besides, we take advantage of the Re-ID network based on attention mechanism, then combined with a spatial constraint strategy to further boost the performance between different cameras. The experiments demonstrate that our solution achieves state-of-the-art accuracy while being real-time in practice. Besides, we will release the code and annotated fisheye dataset for the benefit of community.
