Crowds monitoring can be of critical relevance, expecially when dealing with large scale locations, such as airports, supermarkets and stadiums, where crowds tend to appear for many different reasons. The use of automated techniques for monitoring crowds, such as estimating a crowd’s density, tracking its movements (and even observing its behaviour) is nowadays necessary in a large number of applications. In fact, areas where people are likely to cluster (e.g. an airport) need careful observation to ensure crowd safety (i.e. ensuring a fast and safe evacuation in case of danger, distributing people over all the available security doors). Crowd density estimation and detection can be of fundamental relevance also when dealing with marketing strategies and investigations, where the ability to observe people concentrations (e.g. inside a supermarket, in correspondence to the exposition of a brand new product) directly translates into an analysis of people main interests. Moreover, in some applications people monitoring through classical video surveillance systems (e.g. CCTV) may not be the proper choice, or in some cases it may even be not feasible (e.g for privacy reasons). In those scenarios, it would be of great interesest the use of the avaliable wireless infrastructure to infer informations about crowd density and movements, by simply analyzing the electromagnetic field distribution inside a wide area. |
