Abstract

The invention discloses a block indoor positioning system and method based on wifi and face recognition, and belongs to the field of indoor positioning, and the system comprises a cloud system, a positioning terminal, and a mobile phone terminal. The mobile phone terminal comprises a camera module and a wifi module, and the camera module is used for collecting a current face image of a locator; the positioning terminal comprises a single-chip microcomputer and a camera in bidirectional signal connection with the single-chip microcomputer, and the camera is used for shooting a face image of a positioned person; the camera module is connected with the single-chip microcomputer through a 4g network or wifi to carry out face image information transmission of a localizer. The cloud system comprises a positioning target matching system, a block database and a camera database, wherein the block database and the camera database carry out signal transmission with the positioning target matchingsystem through a 4g network or wifi. According to the invention, the indoor area is blocked, the wifi positioning method based on block recognition is adopted to initially position the mobile phone holder, and the face recognition and geometric calculation of the camera are combined for further positioning, so that the indoor positioning precision can be greatly improved.

Description

technical field [0001] The invention belongs to the technical field of indoor positioning, and in particular relates to a block-based indoor positioning system and method based on wifi and face recognition. Background technique [0002] In recent years, with the wide application of wireless networks, indoor positioning technology has been continuously developed, and indoor positioning methods based on various technical methods emerge in endlessly. The existing indoor positioning technologies in China include Bluetooth positioning, wifi positioning, infrared positioning, geomagnetic indoor positioning, etc. However, due to the strong dynamics of the indoor environment, when wifi or Bluetooth is used alone for positioning, the beacon coverage is low, and the positioning accuracy is relatively low. Low and poor stability and other issues. Contents of the invention [0003] The purpose of the present invention is to provide a block-based indoor positioning system and method b...
