The increase in security threats and a huge demand for smart transportation applications for vehicle identification and tracking with multiple non-overlapping cameras have gained a lot of attention. Moreover, extracting meaningful and semantic vehicle information has become an adventurous task, with frameworks deployed on different domains to scan features independently. Furthermore, approach identification and tracking processes have largely relied on one or two vehicle characteristics. They have managed to achieve a high detection quality rate and accuracy using Inception ResNet and pre-trained models but have had limitations on handling moving vehicle classes and were not suitable for real-time tracking. Additionally, the complexity and diverse characteristics of vehicles made the algorithms impossible to efficiently distinguish and match vehicle tracklets across non-overlapping cameras. Therefore, to disambiguate these features, we propose to implement a Ternion stream deep convolutional neural network (TSDCNN) over non-overlapping cameras and combine all key vehicle features such as shape, license plate number, and optical character recognition (OCR). Then jointly investigate the strategic analysis of visual vehicle information to find and identify vehicles in multiple non-overlapping views of algorithms. As a result, the proposed algorithm improved the recognition quality rate and recorded a remarkable overall performance, outperforming the current online state-of-the-art paradigm by 0.28% and 1.70%, respectively, on vehicle rear view (VRV) and Veri776 datasets.
安全威胁的增加和对智能交通应用的巨大需求,如使用多个非重叠摄像机进行车辆识别和跟踪,引起了广泛关注。此外,提取有意义和语义的车辆信息已成为一项具有挑战性的任务,不同领域部署的框架独立扫描特征。此外,识别和跟踪方法在很大程度上依赖于一两个车辆特征。虽然它们使用 Inception ResNet 和预训练模型实现了高检测质量率和准确性,但在处理移动车辆类别方面存在局限性,不适合实时跟踪。此外,车辆的复杂性和多样化特征使得算法无法有效地在非重叠摄像机之间区分和匹配车辆轨迹。因此,为了消除这些特征的歧义,我们提出在非重叠摄像机上实现三元流深度卷积神经网络(TSDCNN),并结合形状、车牌号码和光学字符识别(OCR)等所有关键车辆特征。然后,联合研究视觉车辆信息的战略分析,以在算法的多个非重叠视图中查找和识别车辆。结果表明,所提出的算法提高了识别质量率,并在车辆后视图(VRV)和Veri776 数据集上分别比当前在线最先进的范例提高了 0.28%和 1.70%。
