Problems solved by technology

[0004] The technical problem to be solved by the present invention is that in the existing large indoor buildings, the structure is complex and it is difficult to meet people's daily needs only by map illustration, which often requires a lot of wasted time and energy and brings a lot of inconvenience. The purpose is to provide a 3D visualization is suitable for indoor navigation systems in theaters and libraries, providing people with a visual and realistic navigation system that can provide users with fast and accurate indoor guidance and positioning services

Embodiment 1

[0029] Such as figure 1 As shown, the present invention provides a three-dimensional visualization indoor navigation system suitable for theaters and libraries, including an indoor BIM three-dimensional simulation system 1, a positioning module 2 and a handheld terminal 3, and the indoor BIM three-dimensional simulation system 1 and the handheld terminal 3 Data interaction is realized through wireless communication technology, and the positioning module 2 and the handheld terminal 3 realize data transmission through two-dimensional code scanning technology;

[0030] The indoor BIM three-dimensional simulation system 1 is used to perform coordinate transformation on the positioning information obtained by the user, add it to the three-dimensional building information, form the user's position information and navigation information in the form of virtual reality, and finally convert the indoor three-dimensional navigation information Send to the handheld terminal 3 for display; ...

Embodiment 2

[0034] Further improvement on the basis of Embodiment 1, the indoor BIM three-dimensional simulation system 1 includes a BIM three-dimensional building module, a storage module, a positioning information receiving module and a navigation information real-time sending module; the BIM three-dimensional building module is used to build a theater or The visualized three-dimensional model of the indoor spatial position of the library is added to the visualized three-dimensional model after coordinate transformation based on the positioning information obtained by the user and the user's current azimuth angle information, and the three-dimensional navigation information is formed according to the target position input by the user; The storage module is used to store the visualized three-dimensional model of the theater or the indoor space position of the library built by the BIM three-dimensional building block; the positioning information receiving module is used to receive the posit...

Embodiment 3

[0038] Further improvement on the basis of Embodiment 2, the handheld terminal 3 adopts a smart phone. The target location information includes the specific name of the target location and keywords related to the target location; the indoor BIM three-dimensional simulation system 1 is also used to store the specific name of the target location and the keywords related to the target location, and is related to the target location according to the target location sent by the handheld terminal 3. The keywords are matched with the stored target location information, and three-dimensional navigation information is provided for the user to choose according to the order of matching degree from high to low.

[0039] For example, for a theater, after the user arrives in the theater room, he or she scans a QR code near the current location with a smartphone, sends the decoded positioning information to the indoor BIM 3D simulation system 1, and enters the keyword "XX piano music" Send i...

Abstract

The invention discloses a three-dimensional and visual indoor navigation system suitable for theaters and libraries. The three-dimensional and visual indoor navigation system comprises an indoor BIM three-dimensional simulation system, a positioning module and a handheld terminal, wherein the indoor BIM three-dimensional simulation system is used for performing coordinate conversion on positioning information acquired by a user, adding the positioning information to three-dimensional building information so that position information and navigation information of the user are formed in a virtual reality manner and sending the indoor three-dimensional navigation information to the handheld terminal for display; the positioning module is arranged in rooms of the theaters or libraries and used for acquiring positioning information of a corresponding position through the handheld terminal; the handheld terminal is used for sending the current position positioning information acquired with a two-dimensional code scanning technique to the indoor BIM three-dimensional simulation system and receiving and displaying indoor three-dimensional navigation information sent by the indoor BIM three-dimensional simulation system. The visual navigation system with high reality sense is provided for people and can provide rapid and accurate indoor guidance and positioning services for users.

Description

technical field [0001] The invention relates to a navigation system, in particular to a three-dimensional visualization indoor navigation system suitable for theaters and libraries. Background technique [0002] At present, convenient outdoor navigation services such as Baidu Maps and Google Maps have been widely used, bringing great convenience to people's daily travel. However, compared with outdoor navigation services, indoor navigation has not been well resolved. With the development of my country's economy, the structure of urban buildings is becoming high-rise and complex. For example, for some university libraries or large public libraries, theaters and other buildings with complex internal structures, people often encounter buildings in the library. Or look for the target area or target site everywhere in the theater. Even if there are guide maps indoors, it is difficult to meet people's daily needs by simply showing multiple floors, hundreds of thousands of square ...
