Accurate navigation system used for guiding indoor mall shopping, exhibition and sightseeing

Abstract

The invention discloses an accurate visible navigation system used for guiding indoor mall shopping, exhibition and sightseeing. The system comprises an indoor accurate real-time positioning system, an indoor wireless communication system, a portable terminal and a server, wherein after entering an indoor mall, an exhibition hall or a scenery hall, a user can check the information of an article by the portable terminal; and after finding the needed articles, the user can read or listen to relative introductions on the articles by the portable terminal, and can realize the accurate visible navigation of the arrival route of the articles by the portable terminal, thereby quickly and accurately finding the articles. The system determines the current three-dimensional space position of the portable terminal by utilizing the indoor accurate real-time positioning system, and a separate label does not need to be attached to each article or a display rack thereof. Therefore, the system has the advantages of convenient installation and flexible usage and is especially suitable for guiding the mall shopping, the exhibition, the sightseeing and the like under indoor environment.

Description

technical field [0001] The invention relates to an indoor precise real-time positioning technology, in particular to an accurate visual navigation system for indoor shopping guides, exhibition guides and scenery guides, and belongs to the technical field of electronic communication navigation. Background technique [0002] In the traditional way of shopping in shopping malls, customers need to find the products they need in the mall or rely on the guidance of the staff in the mall.

Problems solved by technology

Satellite positioning technology is a widely used outdoor positioning technology, but the positioning accuracy of civilian satellite positioning technology is low, and the positioning accuracy range that can be achieved is 5 meters to 20 meters. It is difficult to achieve accurate positioning of indoor scenes, especially for closely arranged accurate indoor scene positioning, and it is impossible to achieve accurate visual navigation of the arrival route of the scene in the indoor environment
