Marketplace indoor positioning navigation method and system based on two-dimensional bar code

Abstract

The invention relates to a marketplace indoor positioning navigation method and system based on two-dimensional bar codes. The navigation method comprises the steps that (1), two-dimensional bar code labels are established in shops of a marketplace, thereby forming a two-dimensional bar code system, and marketplace shopping guide machines are established in the marketplace; (2), mobile terminals enter marketplace center shopping guide service platform by scanning the two-dimensional bar code labels or the two-dimensional bar code labels on the touch screens of the marketplace shopping guide machines through utilization of a wireless communication network and establish connection relationships with the marketplace center shopping guide service platform, and a marketplace internal wireless communication network is responsible for data interconnection between the mobile terminals and the marketplace center shopping guide service platform; and (3), the marketplace center shopping guide service platform collets information of the two-dimensional bar code labels sent by the mobile terminals, then compares the information with a marketplace two-dimensional bar code address library, judges positions of the mobile terminals, provides positioning service for the mobile terminals and displays a marketplace map. The navigation system comprises the marketplace shopping guide machines, the two-dimensional bar code system, the mobile terminal and the marketplace center shopping guide service platform.

Description

technical field [0001] The invention relates to the technical field of indoor navigation in shopping malls, in particular to a method and system for indoor positioning and navigation of shopping malls based on two-dimensional codes. Background technique [0002] Today's large-scale shopping malls gather a large number of stores, occupy a large area, and provide a wide variety of commodities. The main products are clothing, textiles, household goods, food and entertainment products. In order to allow customers to quickly find the products they need to buy, there will be some shopping guides inside the mall. Existing shopping guide measures generally include shopping guide service desks, print media advertisements, location guide signs, etc. These shopping guide measures occupy a large area and space, are relatively simple in communication, and lack interaction; and when information changes, it is laborious to change the shopping guide measures It is easy to cause waste of re...

AI Technical Summary

Problems solved by technology

[0004] 1. The WI-FI positioning technology relies on the Wi-Fi hotspot location distribution database or the received signal strength fingerprint database to achieve positioning. The main problem to be solved is to reliably generate and dynamically maintain the database, and at the same time, it must be low-complexity, so that it can be used in a large number of used in the construction of

[0005] 2. The overall positioning accuracy of ultrasonic positioning is high, and the structure is simple, but ultrasonic is greatly affected by multipath effects and non-line-of-sight propagation, and requires a large amount of investment in underlying hardware facilities, and the cost is too high

[0006] 3. Satellite positioning technology is indoors, and satellite signals are easily blocked by buildings, resulting in the inability to achieve positioning, and cannot distinguish floor information, and cannot achieve accurate positioning

The construction method of the shopping guide system based on the positioning two-dimensional code needs to install a new APP program on the mobile terminal, which makes it inconvenient for users to use, and also makes some users unwilling to use it.
