(Configuration of indoor wayfinding device using digital signage)

An indoor navigation device using a digital signage according to an embodiment of the present invention relates to a device for implementing augmented reality so that a destination can be easily and conveniently found indoors in a specific area. Hereinafter, an indoor route finding or navigation device using a digital signage according to an embodiment of the present invention will be described with reference to the accompanying drawings.

As shown in FIG. 1 , a digital map for directions or guidance of an indoor destination existing within a specific area is created based on the location of the digital signage. In other words, since GPS signals cannot be received indoors, it is not possible to receive route guidance to the destination through the Directions app. Therefore, in the present invention, the position of the digital signage 100 installed in a specific area is used as an absolute reference position to generate the location coordinates of each store or restaurant existing in the area, and a digital map of the room is created.

As an example, assuming that the first digital signage 100a and the second digital signage 100b are respectively disposed at preset positions as shown in FIG. 4 , as shown in FIG. 3 , the first digital signage Based on (100a, departure point (10)), the first relative position coordinates and first digital map of each of stores 1 to 16 are created, and based on the second digital signage (100b, departure point (10)), store 1 To create a second relative position coordinates and a second digital map of each of the stores 16. In this case, the first and second relative position coordinates of each store may be stored including first and second movement direction information for reaching each store. In the present invention, relative position coordinates (including altitude), movement direction information, indoor digital map, or landmark information (to be described later) may be referred to as movement route information. However, the indoor digital map produced based on a specific digital signage may include all movement route information such as relative location coordinates (including elevation coordinates) and landmark information of each store. As an example, it may be information for guiding a movement distance and movement direction for guiding a route from the first digital signage 100a to the target store 4 . Therefore, within a specific area, a user who wants to be guided to a route of an indoor destination existing within the area has an advantage in being able to receive information about the indoor destination route from the digital signage 100a, 100b in which he or she is located, as will be described later. More specifically, in FIG. 3 , relative location coordinates or movement direction information for each store based on the location of each digital signage is stored in advance in the database. Accordingly, the user who wants to receive the route guidance of the indoor destination receives route information to the indoor destination based on the selected digital signage as the user inputs the destination. As shown in FIG. 4 , in the case of inputting the destination store 4 in the first digital signage 100a and in the case of inputting the destination store 4 in the second digital signage 100b, each digital signage is used as a reference can be provided with different movement route information.

The digital signage 100 is disposed in a specific area of the room as shown in FIG. 4 to provide a variety of information to the display screen through text or images, and uses the indoor destination route information generated according to the user's indoor destination input as a route. It is provided through a guide object. As shown in FIG. 2 , the input unit 110 of each digital signage receives an indoor destination from a user through a touch screen or a keypad. The input unit 110 receives a variety of information as well as an input of an indoor destination from the user to provide desired information to the user through a digital signage.

The route information request unit 120 requests the server for route information of the indoor destination input by the user. In this case, the request for route information of the indoor destination may include landmark information to be described later. That is, when the store 11 is input as the destination in FIG. 4 , the route information requesting unit 120 requests the indoor route information of the store 11 as the destination from the server. In this case, as described above, when the store 11 is inputted in the first digital signage 100a and when a route request is made by inputting the store 11 in the second digital signage 100b, it is natural that different routes are transmitted. When the server receives a route request for the destination store 11, the server receives the indoor movement route information (relative location coordinates, movement direction information, digital map map or landmark information) from the database to the store 11 created based on the digital signage. Send back to digital signage.

The route information generator 131 regenerates the indoor destination route information based on the indoor movement route information transmitted from the server, and displays the entire route to the indoor destination through the display unit.

The landmark information generating unit 132 receives and regenerates the landmark information from the server according to the request of the route information requesting unit. The landmark information is information that can be used to compare and determine path errors during route guidance using augmented reality from a terminal to a destination. The landmark information may be, for example, a feature point of each store, a statue existing on a path, or an arrow displayed on a sidewalk. For example, if there is an "elephant statue" somewhere on the route to store 11, the elephant statue may be landmark information, and if there is an elephant statue in the middle of augmented reality guidance, it may be determined that there is no route error. The landmark information may be created and stored together with the landmark information when creating the above-described indoor digital map.

The navigation object generator generates a navigation object that stores at least one of relative location coordinates, movement direction information, indoor digital map, and landmark information that are movement route information of an indoor destination. The generated navigation object is displayed on the screen through the display unit 170 . As an example, the navigation object may be a QR code. As another example, the navigation object may be a virtual character. The QR code is generated by the QR code generating unit, and the virtual character is generated by the virtual character generating unit. The QR code is photographed by the terminal as described later, and the terminal recognizes the QR code and receives a moving route of the indoor destination. The virtual character is a virtual character that can interact with the terminal, and the application installed on the terminal and the virtual character displayed on the screen of the digital signage interact with each other to obtain the movement route data of the indoor destination in the digital signage to the terminal. can be sent to

As shown in FIG. 5 , when the user inputs or selects a destination as “restaurant A” in the digital signage 100 in front of him, indoor route guidance data from the server to “restaurant A” is transmitted. Using the indoor route guidance data transmitted from the server, the digital signage 100 generates a QR code 60 as shown in FIG. 6 or a virtual character 70 as shown in FIG. 7 . At this time, the generated QR code 60 or virtual character 70 is an object in which indoor route information to the input destination is converted. The terminal 200 may receive guidance on the route of the indoor destination by photographing the generated QR code 60 as shown in FIG. 8 . It will be described in more detail below.

As shown in FIGS. 1 and 2 , the terminal 200 guides a route to an indoor destination through augmented reality based on indoor destination route information obtained through a route guidance object. At this time, as described above, based on the location coordinates of the digital signage selected by the user, the route of the indoor destination is guided through the augmented reality. That is, even in the same terminal, as shown in FIG. 4 , the augmented reality route information and the second digital signage 100b that guide using route information from the first digital signage 100a to the destination store 11 are used. ), the augmented reality route information that guides using the route information to the store 11, which is the destination, is different from each other.

As shown in FIG. 8 , the camera unit 242 of the terminal captures the QR code in which the entire route information to the indoor destination is stored. In addition, the camera unit 242 acquires an actual image by photographing a front image. The terminal 200 maps (or synthesizes) a real image and a virtual image of the front acquired in real time through the camera unit to provide the user with directions to the destination through augmented reality. As described above, when the virtual character 70 is used, route guidance information may be provided through mutual interaction between the virtual character 70 and the terminal 200 displayed on the screen of the digital signage. That is, the app of the terminal requests the indoor destination route information to the virtual character 70 displayed on the screen, and the virtual character 70 that has received the request transmits the indoor destination route data together with the authentication method through communication means such as Bluetooth to the terminal. By doing so, the terminal can acquire the route data. By utilizing the virtual character 70 displayed on the digital signage, more interest and fun may be induced, and information on store information that may cause interest on the route of the destination may be obtained. Information transmitted from the digital signage to the terminal may include various event information or promotional information that may be provided to the user on the entire route to the destination in addition to the indoor destination route information.

The QR code recognition unit 251 recognizes and analyzes the QR code photographed from the camera unit 242 to extract indoor destination route information. In this case, event information or promotional information may also be extracted. The landmark recognition unit 252 recognizes and extracts landmark information from the QR code.

The augmented reality route guide 220 guides the route through augmented reality on the screen of the terminal to the indoor destination based on the indoor destination route information and landmark information as shown in FIGS. 9 to 13 . At this time, the augmented reality route guide 220 receives the current movement information of the terminal through the location calculator that calculates the movement direction, movement speed, and movement distance, which are movement information of the terminal. The augmented reality path guide 220 guides the path through augmented reality using current movement information and indoor destination path information of the terminal. That is, when recognizing the first route information of "turn right after going straight 10m from the starting point 10", the augmented reality path guide 220 uses the augmented reality to display the augmented reality path object corresponding to "turn right after going straight 10m" through the augmented reality terminal. displayed on the screen, and the user walks along it. In this case, whether the user has gone straight "10m" may be calculated through the location calculator. The position calculator may include the inertial sensor unit 241 or may calculate the current position based on indoor positioning technology using a Wi-Fi signal.

On the other hand, the augmented reality path object may be an arrow 90 indicating augmented reality path guidance or at least one of a destination direction, an expected distance, and an expected movement time. It is preferable that the augmented reality route guidance arrow 90 is displayed in different colors so that the user can easily recognize it on the screen of the terminal, and it is displayed to gradually increase or decrease in the direction of the destination in the front in order to draw the user's attention more. It is preferable to be If necessary, the arrow 90 may be turned on or off.

The virtual character generating unit 230 generates a virtual character 70a that smoothly assists in guiding a path while being guided to an indoor destination by the augmented reality path guiding unit 220 . That is, the virtual character 70a may be displayed on the screen of the terminal 200 while guiding a route, and may transmit various information by performing a mutual interaction with the user. As an example, when there is store discount information on the route as shown in FIG. 10 , the information may be notified to the user through the virtual character 70a , or a route guidance message may be delivered through the virtual character 70a in FIG. 9 . The virtual character 70a may be an augmented reality object capable of delivering route guidance and various information to a user by interworking with indoor destination route information.

11 , the path error comparison determination unit 260 compares the landmark information extracted from the landmark recognition unit 252 and the actual landmark input from the camera unit 242 with each other to determine whether they are the same landmark. By comparing and judging , it is possible to compare and determine path errors during navigation using augmented reality. By transmitting the landmark information to the terminal through the QR code in this way, if the user walks on the wrong path while receiving directions, it is possible to inform the user that the user is walking on the wrong path. Such landmark information may be stored when creating an indoor digital map or may be stored through later update.

The augmented reality route guidance arrow 90 shown in FIGS. 9 to 11 is expressed in augmented reality by tracking real objects photographed from the camera unit 242 . That is, if the floor of the corridor is not tracked, the arrow 90 cannot be attached to the floor of the corridor. Therefore, the present invention can realize realistic augmented reality by recognizing and tracking (or tracking) the floor of the hallway, merging the augmented reality route guidance arrow 90 on the floor of the hallway and displaying it on the terminal. Figure 12 shows that the user rides the elevator 50 to go upstairs, it can recognize and track the elevator floor, merge the augmented reality route guidance arrow 90 on the elevator floor, and display it on the terminal.

13 is a diagram showing that the final destination "restaurant A" has almost arrived, and it is possible to end the indoor navigation through augmented reality.

On the other hand, as an example, as shown in FIG. 4 , when the first digital signage 100a is the starting point 10 to guide the indoor route to the store 16, the user is guided along the received route and suddenly in the vicinity of the store 6. When the user wants to change the final destination to store 9 instead of store 16, it is necessary to guide the route of the indoor destination again. At this time, the route change request unit 270 requests the digital signage to change the indoor destination during the route guidance using augmented reality through a virtual character. That is, when the user requests to change the destination by performing a mutual interaction with the virtual character, the route change request unit 270 transmits a route change request message to the digital signage. The terminal and the digital signage are connected and connected through respective communication units. When sending a route change request message to a digital signage, the location information of the current terminal must also be transmitted. Accordingly, the location information generator 280 generates indoor location information of the current terminal converted based on the reference coordinate location of the digital signage, and includes it in the route change request message. The communication unit of the terminal transmits the changed indoor destination information and the current location information of the terminal to the digital signage.

The route error comparison determination unit 150 of the digital signage that has received the route change request message compares and determines the route error of the destination before the change based on the current location information of the terminal, and when it is determined that it is a route error, the route error message is sent to the terminal send to

Meanwhile, the digital signage route information request unit 120 transmits the transmitted current location of the terminal to the server, and requests the newly changed route information of the indoor destination by using the current location of the terminal as a reference location coordinate. The route information generating unit 131 regenerates the route information of the changed indoor destination transmitted from the server and transmits it to the terminal. The terminal guides the route information of the newly changed indoor destination through augmented reality again.
