Abstract

The augmented reality (AR) based indoor navigation application is designed for the increased demand of indoor navigation. Unlike current indoor navigation solutions, it uses augmented reality (AR) technique and presupposed 3D indoor mappings to locate user position and recognize the area. It does not require any external equipment like sensors and has the advantages of easy to build, low cost, high accuracy, no external equipment needed and has the ability of function expansion, like user can share the indoor position to others.

Description

AUGMENTED REALITY(AR) BASED INDOOR

NAVIGATION APPLICATION

BACKGROUND OF THE INVENTION

[0001] An indoor navigation system is a system that allows users to locate themselves and lead their way to any facility or destination in a building while they are physically inside the building. Normally, there are two ways to build an indoor navigation system which are based on Bluetooth or WIFI techniques. However, both these two methods have limitations, for example, they all need external sensors installed inside the building to locate the position of user and the accuracy is low. However, these days, the demand of using indoor navigation is increased, then we come up with this invention.

[0002] Unlike the methods above, this invention is based on Augmented Reality (AR) and presupposed 3D indoor mappings.

It is highly related to the field of computer vision and can be used in many indoor environments, like schools, museums, galleries and shopping malls. The advantage of this invention is easy to build, low cost, high accuracy, no external equipment preinstalled in a building and has the ability of function expansion, like users can share the indoor position accurately to others.

[0003] The only requirement to use the invention is to have a smartphone which support AR technique. To implement this invention, a 1:1 scaled 3D building model is required. The process of how this invention is implemented can be seen in the block diagram. 1 is a 3D building mapping, which include a 1:1 scaled 3D model of the building and some building information, like facilities' location and room location, this building information are stored in 2, an online database, the APP can access the database and get these data when required. This 3D building mapping also include a spawn point, labelled as 3, it is located at the gate of the 3D building and it is a reference point. 4 is the process of scanning surroundings when using the app, there is a presupposed reference image in the app labelled as 5, when scanning, if there is an image matches 5, then user's current position will superpose with 3, and the whole real building will superpose with 1. This process is called area recognition and user locating. Meanwhile, the app will access 2 and load all this information for further search matching. When user's input destination matches the information in the database, then a path will be generated from user's current location to the destination. While the user is approaching to the destination, if another reference image is scanned, the user can choose to update the location of himself in the building to cancel the accumulated error during his movement (7). When the user arrives the destination, user can choose 9, close the app or go back to 6, search for another destination.

Claims

1. This augmented reality (AR) based application are implemented using all three tools that are ARKit (IOS), ARCore (Android) and Vuforia's image matching technique, then corporate with an presupposed 3D indoor mappings(3D building model) to locate user current position, any other people or third party can not use the same procedure to make an AR based indoor navigation application without the inventor's permission .

2. The augmented reality (AR) based application as claimed in claim 1, is not only used to build navigation application, but also can be used in mobile games, any other people or third party can not use the same procedure to make an AR indoor navigation based mobile games without the inventor's permission.
