Application of the SSD Algorithm in a People Flow Monitoring System

For places where people flow concentrates, such as scenic spots, bus platforms, and shopping mall entrances, it is important to regulate and disperse the people flow where. This system uses an object detection algorithm named Single Shot Multibox Detector (abbreviated as SSD) to monitor the people flow in various public places. The system includes the following two parts: the embedded application layer, and the web application layer. The lightweight embedded device based on the SSD object detection algorithm can realize realtime monitoring statistics and detect abnormal crowd condition monitoring. It is convenient for managers of public places to know the flow of people in an area in realtime to deal with emergencies promptly and dispatch staff. Meanwhile, the system can improve people's experience and reduce the potential harm caused by overcrowding.
