Smart Camera-based Contact Tracing Systems: A Review

With the spread of the COVID 19 virus and the threat of a pandemic, the World Health Organization (WHO) proposed quarantine and setting social distancing restrictions as a means of disease management. Despite their effectiveness, implementing and administering these restrictions is prohibitively expensive and not suitable for a long time. Contact tracing systems can be used as an alternative to public quarantine. Smart cameras are an easily accessible structure for developing such a system due to their widespread use. However, there are numerous challenges in designing and implementing the mentioned system. The architecture of an effective object detection model, a large enough dataset, and a method for positioning and tracing people are some of the challenges that have been examined and compared in this article.
