论文摘要
车辆重新识别(RE-ID)是自主驾驶感知系统的关键组成部分,近年来在该领域的研究加速了。但是,目前尚无与汽车环绕摄像头系统相关的车辆重新识别问题的完美解决方案。我们的分析在上述方案中确定了两个重要问题:i)由于鱼眼相机的独特构造,很难在许多相框中识别同一辆车辆。 ii)当通过环绕视觉系统的几个摄像机看到时,同一辆车的外观大不相同。为了克服这些问题,我们建议一种综合车辆重新ID解决方案方法。一方面,我们提供了一种技术来确定跟踪框相对于目标的一致性。另一方面,我们根据注意机制将重新ID网络与空间限制相结合,以在涉及多个相机的情况下提高性能。最后,我们的方法结合了最先进的精度和实时性能。我们很快将制作源代码和带注释的Fisheye数据集。
Vehicle re-identification (Re-ID) is a critical component of the autonomous driving perception system, and research in this area has accelerated in recent years. However, there is yet no perfect solution to the vehicle re-identification issue associated with the car's surround-view camera system. Our analysis identifies two significant issues in the aforementioned scenario: i) It is difficult to identify the same vehicle in many picture frames due to the unique construction of the fisheye camera. ii) The appearance of the same vehicle when seen via the surround vision system's several cameras is rather different. To overcome these issues, we suggest an integrative vehicle Re-ID solution method. On the one hand, we provide a technique for determining the consistency of the tracking box drift with respect to the target. On the other hand, we combine a Re-ID network based on the attention mechanism with spatial limitations to increase performance in situations involving multiple cameras. Finally, our approach combines state-of-the-art accuracy with real-time performance. We will soon make the source code and annotated fisheye dataset available.
