Abstract

The invention provides an indoor positioning method. The method comprises the following steps: S101: an architectural drawing (a design drawing, a production drawing, an effect picture and the like) of a space to be positioned is converted into an indoor map with an absolute coordinate through first-grade control point plotting and coordinate transformation; S103: latitude and longitude coordinates of multiple second-grade control points in the indoor map are determined, positioning two dimensional codes are generated, and the positioning two dimensional codes are attached to positions corresponding to the multiple second-grade control points indoors; S105: the latitude and longitude coordinates corresponding to the positioning two dimensional codes are scanned and read through an intelligent terminal, and indoor positioning is achieved in cooperation with the indoor map. The invention provides an indoor positioning system. The provided indoor positioning method converts the architectural drawing into an indoor map through coordinate transformation, the working intensity of manual plotting is lowered effectively, and the working efficiency is raised. In addition, indoor positioning is carried out by utilization of two dimensional codes on this basis, the method is simple and convenient, and the cost can be lowered effectively.

Description

technical field [0001] The invention relates to the technical field of indoor positioning, in particular to an indoor positioning method and system for generating a positioning two-dimensional code based on a building map. Background technique [0002] Indoor positioning refers to the realization of position positioning in the indoor environment. It mainly adopts wireless communication, base station positioning, inertial navigation positioning and other technologies to form an indoor position positioning system, so as to realize the position monitoring of people and objects in the indoor space. Common indoor wireless positioning technologies mainly include: WiFi, Bluetooth, infrared, ultra-wideband, RFID, ZigBee and ultrasonic. However, currently the indoor Figure 1 Generally, manual measurement is required, and the workload is heavy and complicated. Contents of the invention [0003] Based on this, it is necessary to provide an indoor positioning method and system for t...
