Intelligent Transport System should be renovated in many aspects in post-pandemic situation like COVID-19. The passenger-count inside a car will be restricted based on the vehicle capacity and the COVID-19 hot-spot zone. Traffic rules will be impacted to align with a similar contagious outbreak. The on-road 'Yellow-Vulture' cameras need to incorporate such surveillance rules to monitor related anomalies for preventing contamination. To maintain safe-distance, an automatic surveillance system will be preferred by the Government very soon. Moreover, facial mask usage during the journey has become an essential habit to stop the spread of the infection. In this article, we have proposed a deep-Learning based framework that employs an augmented image data set to provide proper surveillance in the transport system to maintain the health protocols. Fast and accurate detection of the number of passengers inside a car and their face masks from the traffic inspection camera feed has been demonstrated. We have exploited the advantages of the popular Transfer Learning approach with novel variations of images while performing the training. To the best of our knowledge, this is the first attempt to watch over in-vehicle social-distancing in post-pandemic circumstances through deep-Learning based image analysis. The superiority of the proposed framework has been established over several state-of-the-art techniques using different numerical metrics and visual comparisons along with a support of statistical hypothesis test. Our technique has achieved testing accuracy in various adverse conditions. Zero-shot evaluation has been explored for the Real-Time-Medical-Mask-Detection data set Wang et al. (Real-Time-Medical-Mask-Detection, 2020a https://github.com/TheSSJ2612/Real-Time-Medical-Mask-Detection/, Accessed 14 Nov 2020), where we have attained accuracy that manifests the generalization of the network.
在新冠疫情等大流行后的情况下,智能交通系统应在许多方面进行革新。车内乘客数量将根据车辆载客量和新冠疫情热点区域进行限制。交通规则将受到影响,以适应类似的传染病爆发情况。道路上的“黄鹰”摄像头需要纳入此类监控规则,以监测相关异常情况,防止污染。为保持安全距离,政府很快会优先采用自动监控系统。此外,出行时佩戴口罩已成为阻止感染传播的基本习惯。在本文中,我们提出了一个基于深度学习的框架,该框架采用增强图像数据集,以便在交通系统中进行适当监控,以维持健康协议。已经展示了从交通检查摄像头画面中快速准确地检测车内乘客数量及其口罩佩戴情况。在进行训练时,我们利用了流行的迁移学习方法的优势,并采用了新颖的图像变体。据我们所知,这是首次尝试通过基于深度学习的图像分析,在大流行后的情况下监控车内社交距离。通过使用不同的数值指标、视觉比较以及统计假设检验的支持,已证明所提出框架优于几种先进技术。我们的技术在各种不利条件下都达到了测试精度。我们还对Wang等人(实时医用口罩检测,2020a https://github.com/TheSSJ2612/Real-Time-Medical-Mask-Detection/,访问时间:2020年11月14日)的实时医用口罩检测数据集进行了零样本评估,我们在该评估中达到了 的准确率,这体现了网络的泛化能力。
