Abstract

The invention relates to a method for obtaining crowd information in a set place. The method comprises the following steps that a camera device arranged at a set position in the set place obtains crowd image information data in a preset area; meanwhile, a wireless monitoring device arranged in the preset area obtains recognition information data of mobile communication terminals carried by the crowd in the set area; the image information data and the mobile communication terminal recognition information data which are obtained at the same time are correlated and stored, and scene type information data is obtained. The invention further relates to a device for achieving the method. The method and device for obtaining the crowd information in the set place have the advantages that the recognition workload is small, and mistakes are not prone to being made.

Description

technical field [0001] The invention relates to the field of monitoring, and more specifically, to a method and device for obtaining crowd information in a set place. Background technique [0002] In set areas, such as public places, stations, squares, docks and other places, the flow of people is very large.
