Method, device and system for measuring crowding degree

Abstract

The embodiment of the invention provides a method, device and system for measuring a crowding degree. A terminal samples the signal strength value of access point in an access point coverage area, calculates out mathematical statistical parameters, measures and calculates the distance from an current sampling location to the access point, and informs a server of the distance and the mathematical statistical parameters; the server obtains the distance and the mathematical statistical parameters, an objective function is chosen in a crowding degree corresponding relation table according to the distance and the mathematical statistic parameters, and the crowding degree grade corresponding to the objective function is used to indicate the crowding degree in the access point signal coverage area. According to the method, device and system for measuring a crowding degree, the signal strength of the access point is collected at once, the crowding degree within the space is evaluated through the crowding degree corresponding relation table, image acquisition of the location of each person is not needed, complex computing is needless, the measurement can be achieved only through the terminal carried by the user, extra hardware need not to be arranged, and the cost is reduced.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method, device and system for measuring crowd crowding degree by using a wireless network. Background technique [0002] Location information plays an important role in people's daily life. In unfamiliar environments such as suburbs, exhibition halls, and parks, using positioning and navigation information can provide users with more convenient services. With the continuous expansion of the scope of people's activities and the increasingly complex activities, the current location positioning technology is difficult to meet the needs, especially for places with dense traffic such as subways, buses, shopping malls, libraries, etc., people hope to be able to grasp the crowds in the space in a timely manner This will not only facilitate line configuration by managers and resource allocation by merchants, but also provide users with more useful reference information for user...

Problems solved by technology

[0008] Image recognition technology has a huge amount of calculation, and requires a dedicated chip or processor, and the viewing device is highly dependent on the environment, and cannot handle interference such as lighting, shadows, and occlusions well.
