论文摘要

近年来,在全球范围内解决了强大的智能运输系统(ITS)的开发,以减少频繁的交通问题来提供更好的交通效率。作为其应用,车辆的重新识别对计算机视觉和机器人技术的领域产生了充足的兴趣。开发了基于卷积的神经网络(CNN)方法来执行车辆重新识别,以应对诸如遮挡,照明变化,规模等等关键挑战。计算机视觉中变压器的进步为进一步探索重新识别过程打开了机会,以增强性能。在本文中,开发了一个框架来执行跨CCTV摄像机的车辆的重新识别。为了进行重新识别,提出的框架将使用CNN和变压器模型学习的车辆表示。该框架在一个数据集上进行了测试,该数据集包含在20个CCTV摄像机上观察到的81个独特的车辆身份。从实验中,融合的车辆重新识别框架产生的地图为61.73%,与独立的CNN或变压器模型相比,该框架的地图明显更好。

In recent years, the development of robust Intelligent transportation systems (ITS) is tackled across the globe to provide better traffic efficiency by reducing frequent traffic problems. As an application of ITS, vehicle re-identification has gained ample interest in the domain of computer vision and robotics. Convolutional neural network (CNN) based methods are developed to perform vehicle re-identification to address key challenges such as occlusion, illumination change, scale, etc. The advancement of transformers in computer vision has opened an opportunity to explore the re-identification process further to enhance performance. In this paper, a framework is developed to perform the re-identification of vehicles across CCTV cameras. To perform re-identification, the proposed framework fuses the vehicle representation learned using a CNN and a transformer model. The framework is tested on a dataset that contains 81 unique vehicle identities observed across 20 CCTV cameras. From the experiments, the fused vehicle re-identification framework yields an mAP of 61.73% which is significantly better when compared with the standalone CNN or transformer model.
