Mobile AR guide node device supporting marker function for augmented reality experience {A MOBILE GUIDE NODE AS AN AR MARKER TO SUPPORT AUGMENTED REALITY EXPERIENCE SERVICE}

The present invention relates to an AR guidance node device that is installed in a site to provide an augmented reality experience service and can be utilized as an AR marker for a user terminal app to load an augmented reality object, using a five-color LED lamp as an AR code marker It relates to a mobile AR guide node device that allows users to easily find and remotely set and manage AR code markers in network with content managers and service managers.

Virtual reality (VR) uses special devices and technologies to block the real world to the user and shows virtual images in cyberspace entirely, and augmented reality (AR) is based on GPS location information and built-in smart devices. It is a technology that displays additional virtual 3D images or media information on the real world using a scope. Augmented reality service provides a much more lively guide service by superimposing 3D characters or contents with special stories on the real world in parks, tourist attractions, museums or exhibition halls, as well as online games such as Pokemon GO, and allows users to view surrounding landscapes and virtual images. It is possible to implement special exhibitions such as taking pictures by synthesizing, and related technologies are disclosed in Korean Patent Publication No. 10-2017-0042039 (Augmented Reality-based Guide Method Using Mobile Device), Korean Patent Publication No. It is suggested by No. 10-2019-0061696 (Apparatus and method for realizing interactive AR/MR by driving motion of smart phone) and the like.

AR Marker is a special marker used in a place where you want to experience augmented reality. Usually, when a specific image or character is pasted in the form of a sticker on various places in the service area, the user recognizes the marker with the camera in the experience app of the smart terminal. It is implemented in such a way that it is combined with GPS location information within the app to load an augmented reality object in the corresponding area.

AR code marker is an augmented reality interaction pattern applied with marker-based technology. Even if GPS location information is not separately referred to, a special code marker such as a barcode or QR code is used as a code to distinguish augmented reality objects, The item referenced by the code is loaded and displayed at the location where the code is recognized.

On the other hand, when passing through tourist attractions, hiking trails, or walking trails, you may encounter many wooden or steel information boards that guide geography and directions or introduce tourist attractions. Recently, a variety of tourist information services are provided by local governments that display a QR code on an information board and provide detailed stories or information about a feature when it is recognized with a smart device. In addition, in museums or exhibitions, recognition stickers for augmented reality experiences engraved with special characters or logos are attached here and there, and when the sign attached to the floor or wall of a building is recognized by the user app, augmented reality images or 3D characters are superimposed on the real world. You can enjoy more lively viewing and shooting.

Existing wooden tourist information boards or trail directions require expensive installation costs for on-site installation, and once installed, the content cannot be easily changed. There is a problem that it is damaged over time and the efficiency of use is reduced. In addition, for a short period of 1-2 weeks, various festivals in the community, experience centers, or event exhibitions such as outdoor expos require an AR marker guidance method that can be quickly installed and installed and content information can be easily updated. do.

AR marker guide nodes for augmented reality experiences should be easily identifiable during the day as well as at night outdoors, such as parks, zoos, hiking trails, and walking trails, so that they can perform the function of direction guidance at the same time. It must be able to quickly update and provide content and new images. In addition, for a short period of time, it should be easy to move and install AR markers for various festivals or experience sites in the local community.
