Problems solved by technology

Ultra-wideband communication transmits data by sending and receiving extremely narrow pulses with nanoseconds. Although it has the characteristics of strong penetrating power, high security, and high precision, because of these characteristics, the system consumes high power and requires Layout in advance, the cost cannot be reduced

Embodiment Construction

[0027] The present invention will be further elaborated below through specific embodiments in conjunction with the accompanying drawings.

[0028] 1) Collect indoor structural information of fixed places, draw indoor maps, and establish and complete indoor scene models;

[0029] 2) Based on the prepared indoor map and indoor scene model, the indoor map and indoor scene model are packaged to generate a database, and combined with the positioning and navigation program algorithm, a navigation software is developed, and the navigation software is uploaded to the cloud server;

[0030] 3) Make the identification code corresponding to the indoor target point, the identification code adopts a two-dimensional code, and post or place the corresponding identification code at the actual fixed indoor target point, and the target point corresponds to the identification code one by one;

[0031] 4) The user downloads the navigation software from the cloud server and installs it on the smar...

Abstract

The invention discloses an indoor positioning and navigation method based on scanning of an identification code. According to the method, indoor positioning is performed by adopting a manner of scanning the identification code; the identification code can be a two-dimensional code printed with plain paper, so that the manufacturing cost of the identification code is very low; the identification code is fixed on a wall of an indoor target point in a pasting manner, so that the layout is simple and does not need consume much labor cost, and the subsequent maintenance is very simple. When in navigation, the method comprises three navigation manners: 3D (three-dimensional navigation, character navigation and AR (augmented reality) navigation, especially, the AR navigation can guide directions for a user very intuitively in a virtuality and reality combination manner, so that navigation experience is greatly improved; in addition, the 3D navigation and the AR navigation have a code scanning positioning function, so that when the user deviates a navigation path, a user position can be corrected, and the navigation path can be replanned, therefore, the navigation is more accurate, the path-finding time of the user is saved, and the efficiency is improved.

Description

technical field [0001] The invention relates to indoor navigation technology, in particular to an indoor positioning and navigation method based on scanning identification codes. Background technique [0002] With the rapid development of science and technology, outdoor navigation technology has been very mature and widely used in people's lives. Outdoor GPS positioning technology is very accurate, but after entering the room, due to the complexity of indoor geographic information and the attenuation of GPS signals, GPS cannot be used for navigation. In a complex indoor environment, such as a huge and complicated shopping mall, it is undoubtedly difficult for people to find a certain merchant immediately according to simple instructions. At this time, users only need to start the indoor navigation software, and according to the detailed prompts of the software, they can smoothly find the shops and restaurants they want to go to. [0003] At present, there are several matur...
