Route identification method based on BIM + AR technology

Abstract

The invention discloses a route identification method based on a BIM + AR technology, which can automatically identify the internal routes of a building and analyze a correct route. A user often cannot find the correct route in a large building and needs to search a map everywhere, but the maps may not be corrected in time along with the changes of the routes in a shopping mall or a hospital, so that unnecessary delay is possibly caused. The BIM + AR technology is used for updating building information in time, the Internet of Things technology is used for collecting the building information,so that the method for accurate indoor positioning and rapid correct road search is achieved. By applying the AR technology, the thought of a designer can be fully displayed, and information transmission can be realized by calling a cloud database, so that a user and operation and maintenance personnel can use the system more conveniently and quickly in the later period. The data is acquired through an identification device, and different contents are presented to different users through the AR, so that the later operation and maintenance efficiency of the device can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of building operation and maintenance, in particular to a route identification method based on BIM+AR technology. Background technique [0002] Nowadays, buildings tend to be larger, and there are more and more internal facilities. Once a certain internal structural facility is changed or modified, when we are in a large building, we often cannot find the correct way, and we need to find a guide map everywhere, and With the modification of the layout of the shopping mall or hospital, if the map cannot be corrected in time, if it is not an internal personnel or a person who has been frequently active in the building for a long time, it will basically cause confusion and lead to the failure to find the correct route, which may cause unnecessary delays. How to quickly find a suitable route is a technical problem to be solved now. Contents of the invention [0003] The purpose of the present invention is to s...

If it is not an internal personnel or a person who has been frequently active in the building for a long time, it will basically cause confusion and cause the correct route to be lost, which may cause unnecessary delays.
