Problems solved by technology

Its disadvantages are: no real-time positioning and low positioning accuracy
However, UWB is difficult to achieve large-scale indoor coverage, and mobile phones do not support UWB, so the positioning cost is very high

Embodiment Construction

[0035] The present invention figure is based on the library indoor three-dimensional navigation process of bluetooth and triangulation:

[0036] Library part:

[0037]1. Install the Bluetooth base station. The installation positions of the Bluetooth base station are: installed in each main position of the library; installed at the upper and lower ends of the library bookshelf side: two adjacent bookshelves are installed at the upper end of one and the lower end of the other, and the same bookshelf is installed at one end At the upper end, the other end is installed at the lower end, that is, to maximize the distance between two adjacent Bluetooth base stations and to provide the approximate height of the mobile terminal. The three-dimensional coordinate information of the bookshelf designed by the present invention is represented by a twenty-five-digit integer, the highest digit represents a floor, and the last twenty-four digits represent the three-dimensional position coord...

Abstract

The invention provides a library indoor three-dimensional navigation method based on Bluetooth and triangulation, which mainly solves the problem that a person wastes time and easily gets lost when searching for a book in a library. The method comprising a target book positioning step, a reader positioning step and a navigation step, and is characterized by comparing information of a Bluetooth base station closest to a cell phone of a reader with information in a database and computing, to determine a three-dimensional position of the reader; marking and displaying the reader position in a library schematic map; determining borrowing orders from the reader position to each of target books; computing a path as short as possible between two adjacent targets; providing a relatively short path that can communicate the current position of the reader with all the target books; and marking and displaying same in the library schematic map. The method disclosed by the invention effectively improves book searching efficiency, so that the reader who is not familiar with book arrangement in the library can rapidly find desired books.

Description

technical field [0001] The invention belongs to the technical field of indoor positioning and navigation, in particular to a location service technology supporting indoor maps and navigation. Background technique [0002] At present, there are more and more complex indoor places, such as airport halls, exhibition halls, warehouses, supermarkets, libraries, underground parking lots, etc. in people's lives. In these complex indoor environments, in order to find the desired object, people often have to ask strangers for directions, or turn to the indoor planning maps on the walls. These location-based services are often inefficient and impersonal in places with complex or extremely irregular layouts. Libraries are very typical places that require indoor navigation technology. If you can realize convenient and fast navigation in the library, it will become an easy task for readers to find their favorite books in the "big book sea". [0003] The disadvantage of GPS for indoor ...
