Problems solved by technology

However, the disadvantage of using GPS for indoor positioning is that the positioning signal is weak when it reaches the ground, and the signal cannot penetrate buildings, and the cost of the locator terminal is high
In addition, some indoor wireless positioning technologies, such as infrared, ultrasonic, radio frequency, and Bluetooth technologies, have shortcomings such as small signal application range, poor stability, and susceptibility to noise interference.
It has also been proposed to combine GPS technology with indoor wireless positioning technology, but the technology is complicated and the cost is high

Embodiment Construction

[0036] Library section:

[0037] 1. Paste the QR code picture. The library pastes the QR code pictures containing the book website address in each main location of the library, and the library website provides the library catalog search engine function.

[0038] 2. Generate a library layout map. The map is in the form of a two-dimensional map matrix, and each element in the matrix uses a one-digit integer to represent the bookshelves, aisles, walls, borrowing offices, etc. in the actual layout of each floor. For example: 0 means bookshelf, 1 means aisle, 2 means wall, 3 means library, etc. The number of elements filled in the matrix indicates the proportion of the area occupied by bookshelves and aisles on the floor, and the coordinate information of each element in the matrix indicates the plane position of bookshelves and aisles. According to this method, a two-dimensional map matrix of each floor of the library is established.

[0039] 3. Establish library layout map da...

Abstract

The invention discloses a method of mobile phone navigation in a library and a system of the mobile phone navigation in the library, mainly aiming at solving the problem that a reader is time-wasting for searching books in the library and is easy to be lost. The method for searching the books in a navigation way comprises the steps of: computing information of a target object and information in a data base in a comparing way to confirm a target position, and computing information of a reference object and information in the data base in a comparing way to confirm a reader position; and planning an optimum book reaching route according to the information of the target position and the information of the reader position, and giving a book searching route prompt from the current position of the reader to the position of a series of target books, so that the navigation is realized. The book searching navigation system mainly comprises a bar code (including a one-dimension code and a two-dimension code), a smartphone, a database, a server and the like.

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] GPS (Globle Pozitioning System) is ...
