Coronavirus born COVID-19 disease has spread its roots in the whole world. It is primarily spread by physical contact. As a preventive measure, proper crowd monitoring and management systems are required to be installed in public places to limit sudden outbreaks and impart improved healthcare. The number of new infections can be significantly reduced by adopting social distancing measures earlier. Motivated by this notion, a real-time crowd monitoring and management system for social distance classification is proposed in this research paper. In the proposed system, people are segregated from the background using the YOLO v4 object detection technique, and then the detected people are tracked by bounding boxes using the Deepsort technique. This system significantly helps in COVID-19 prevention by social distance detection and classification in public places using surveillance images and videos captured by the cameras installed in these places. The performance of this system has been assessed using mean average precision (mAP) and frames per second (FPS) metrics. It has also been evaluated by deploying it on Jetson Nano, a low-cost embedded system. The observed results show its suitability for real-time deployment in public places for COVID-19 prevention by social distance monitoring and classification.
冠状病毒引发的 COVID-19 疾病已经在全球范围内蔓延。它主要通过身体接触传播。作为预防措施,需要在公共场所安装适当的人群监测和管理系统,以限制疫情的突然爆发,并提供更好的医疗服务。通过更早地采取社交距离措施,可以显著减少新的感染人数。受此启发,本研究提出了一种用于社交距离分类的实时人群监测和管理系统。在提出的系统中,使用 YOLO v4 目标检测技术将人与背景分离,然后使用 Deepsort 技术通过边界框跟踪检测到的人。该系统通过使用安装在这些地方的摄像机拍摄的监控图像和视频来进行公共场所的社交距离检测和分类,从而显著有助于 COVID-19 的预防。该系统的性能使用平均精度均值 (mAP) 和每秒帧数 (FPS) 指标进行评估。还通过在低成本嵌入式系统 Jetson Nano 上进行部署来对其进行评估。观察到的结果表明,它适合在公共场所实时部署,用于通过社交距离监测和分类来预防 COVID-19。
