Problems solved by technology

[0003] The present invention aims at the shortcomings of the prior art that terminal equipment must be carried for positioning, and provides an indoor positioning method and positioning system based on face recognition
[0004] The present invention solves the problem that terminal equipment must be carried to locate. This design scheme uses a camera to take pictures. The unique algorithm can calculate the precise indoor positions of different personnel through two-dimensional images. The facial recognition algorithm replaces the terminal equipment. The image of the camera is compared with the entered database, and the identity of different personnel can be judged in a timely and efficient manner

Embodiment 1

[0049] Such as figure 1 As shown, an indoor positioning method based on face recognition includes the following steps:

[0050] S10. Divide the indoor area, and set multiple cameras in each sub-area;

[0051] S20, number each person entering the room, collect facial image data, and establish a database;

[0052] S30, the camera shoots indoor images at regular intervals;

[0053] S40, identifying the image collected by the camera, judging whether there is a human face in the image, identifying the captured human face, comparing it with the database, and obtaining the corresponding personnel number;

[0054] S50. Analyze the indoor location information of each person in the collected image, and add the location information into the database according to the obtained personnel number;

[0055] S60. Summarize all the indoor location information of a certain personnel number to generate a movement route map of the corresponding person; or summarize the indoor location informatio...

Abstract

The invention relates to the technical field of indoor locating and discloses an indoor locating method and locating system based on face recognition. The indoor locating method comprises the following steps: dividing indoor areas and providing a plurality of cameras in each subarea; numbering each person entering into the room, collecting facial image data and establishing a database; shooting indoor images by the cameras; identifying the collected images, identifying the shot faces and comparing with the database, thereby acquiring a corresponding person number; analyzing the indoor positionof the person in the collected images and adding the position information into the database according to the acquired person number; collecting the position information of a certain number to generate a motion route map; or collecting the position information of a certain number to generate a personnel distribution diagram in the area. According to the indoor locating method provided by the invention, indoor personnel can be timely and accurately located and tracked and the indoor personnel distribution can be checked at any time; the indoor locating method can be combined with an original indoor monitoring system; the indoor locating method is wide in application scope and high in practicability.

Description

technical field [0001] The invention relates to the technical field of indoor positioning, in particular to an indoor positioning method based on face recognition and the design of a positioning system. Background technique [0002] With the rapid development of mobile terminals and the Internet, real-time positioning is widely used in transportation, commerce, logistics, personalized services and other fields. In an outdoor environment, the global navigation satellite system, such as the Global Positioning System (GPS), can provide relatively accurate positioning services after long-term development. At present, indoor high-precision positioning is mainly through: UWB positioning, Wi-Fi positioning, iBeacon Bluetooth positioning, RFID positioning, etc., all of which need to be held by the positioning personnel or equipped with positioning terminal equipment to perform positioning. It is not suitable for the positioning of students in school classrooms, the positioning of p...
