Method and device for calculating customer traffic volume

A statistical method for customer flow volume, wherein the method comprises:

• obtaining video image information in a preset monitoring area;
• performing video analysis on the video image information and determining a movement direction of a first target person appearing in the preset monitoring area according to an analysis result, the movement direction being a direction of entering an actual detection area of a wireless detector or a direction of exiting the actual detection area, wherein the actual detection area covers the preset monitoring area;
• obtaining, through statistics, incoming customer flow volume or outgoing customer flow volume of the actual detection area according to the determined movement direction of the first target person;
• reading a first terminal identifier, detected by a WiFi detector, of a WiFi terminal apparatus carried by the first target person;
• judging whether the first terminal identifier is present in a preset terminal identifier database for non-customer personnel;
• if so, decreasing the incoming customer flow volume or the outgoing customer flow volume by 1;
• otherwise, making no change to the incoming customer flow volume or the outgoing customer flow volume.
