1 is a block diagram of an augmented reality content providing apparatus according to an embodiment of the present invention. Referring to FIG. 1, a photographing unit 110, an acquisition unit 120, a target object selection unit 130, a providing unit 140, and a display unit 150 may be included.

The photographing unit 110 may photograph a target space located inside the smart display through a camera. For example, the photographing unit 110 may take a picture of the inner space of the aquarium located inside the smart display through the camera.

The acquisition unit 120 may analyze a plurality of objects located in a target space from the captured image to obtain reference information for each object necessary for generating augmented reality content.

Here, the plurality of objects located in the target space may be underwater animals moving in the aquarium, and the reference information for each object may be fish species information. For example, the acquisition unit 120 requests image information for each object from a content providing server (not shown), and image information for each object received from a content providing server (not shown) and a plurality of objects included in the captured image Reference information for each object (eg, clownfish, blue-tang, etc.) may be obtained by comparing image information for each object.

The acquisition unit 120 may acquire location coordinates in which a plurality of objects are located and information on the number of objects for each object based on the spatial coordinates set for the target space. A process of acquiring position coordinates at which a plurality of objects are located will be described in detail with reference to FIG. 2.

2 is an exemplary diagram for describing a process of acquiring position coordinates of a plurality of objects according to an embodiment of the present invention. Referring to FIG. 2, the target space 200 may be composed of three-dimensional coordinates of an x-axis 201, a y-axis 202, and a z-axis 203.

The acquisition unit 120 may acquire position coordinates in which a plurality of objects are located based on spatial coordinates set for the target space 200. For example, the target object acquisition unit 120 acquires the position coordinates of the first object 210 as (x1, y1, z1), and the position coordinates of the second object 220 (x2, y2, z3) Can be obtained with.

Returning to FIG. 1 again, the target object selection unit 130 may select a target object to map augmented reality content from among a plurality of objects based on the acquired reference information. A process of selecting a target object to map augmented reality content from among a plurality of objects will be described in detail with reference to FIGS. 3A to 3F.

3A to 3F are exemplary diagrams for explaining a process of selecting a target object to which augmented reality content is to be mapped from among a plurality of objects according to an embodiment of the present invention.

The target object selection unit 130 may determine whether or not there are at least two objects having the same reference information among the plurality of objects in order to select a target object to which the augmented reality content is to be mapped from among the plurality of objects.

When there are at least two objects having the same reference information, the target object selection unit 130 may select at least one of the same two or more objects as a target object to map the augmented reality content based on preset target object selection condition information. . Here, the target object selection condition information may include linear distance information between the display and the object, object area area information, object location information on the display, object movement speed information, object movement speed change amount information, and the like.

3A is an exemplary diagram illustrating a process of deriving linear distance information between a display and an object among a plurality of objects according to an embodiment of the present invention. 2 and 3A, the target object selection unit 130 may derive linear distance information between each object from the smart display 300 on which the augmented reality content is to be displayed.

For example, suppose that there are 3 fish species A (301 to 303) and 3 fish species B (311 to 313) as objects having the same reference information in the target space 200.

The target object selection unit 130 may derive linear distance information for each of the A species 301 to 303 from the smart display 300. Here, the linear distance information corresponds to the z value of the position coordinates of each object obtained in FIG. 2, and the probability of selecting the linear distance information for the object from the smart display 300 as the target object increases as the z value decreases. have.

For example, the target object selection unit 130 stores the straight line distance information of the A1 object 301 from the smart display 300 among the A species (301 to 303) as'z2' (322) and the straight line of the A2 object 302. Distance information may be derived as'z3' 323 and linear distance information of the A3 object 303 may be derived as'z6' 336.

For another example, the target object selection unit 130 may determine the linear distance information of the B1 object 311 from the smart display 300 among the B fish species 311 to 313 in'z1' 321 and the B2 object 312. The linear distance information may be derived as'z4' 324 and the linear distance information of the B3 object 313 may be derived as'z5' 325.

3B is an exemplary diagram for explaining a process of deriving object area area information according to an embodiment of the present invention. Referring to FIG. 3B, the target object selection unit 130 may derive an area area occupied by each object on the smart display screen when a viewer looks at the smart display 300 in front. Here, the area width of each object may be derived based on the width of the object * the height of the object, and the probability of selecting the target object may increase as the value of the area width of a single object increases.

For example, the target object selection unit 130 may derive area area information of the A1 object 301, the A2 object 302, and the A3 object 303, respectively, of the A species 301 to 303. Here, the area area of fish species A (301 to 303) may be in the order of A3 object 303> A1 object 301> A2 object 302.

For another example, the target object selection unit 130 may derive area area information of the B1 object 311, the B2 object 312, and the B3 object 313, respectively, of the B fish species 311 to 313. Here, the area area of the B fish species 311 to 313 may be in the order of B3 object 313> B2 object 312> B1 object 311.

3C is an exemplary diagram for explaining a process of deriving object location information on a display according to an embodiment of the present invention. Referring to FIGS. 2 and 3C, the object location information may mean a coordinate location on a screen in which an object of the target space 200 is displayed on the smart display. For example, when the horizontal length of the smart display is the x-axis and the vertical length is the y-axis, the position coordinates of the object may be (x, y).

In the smart display, an augmented reality content output area 330 and an augmented reality content non-output area 331 may be set by an administrator in consideration of visibility and UX. Here, the augmented reality output area 330 may indicate an area range to which the augmented reality content is mapped, and the augmented reality content non-output area 331 may indicate an area range to which the augmented reality content is not mapped. The non-output area 331 of the augmented reality content is an area that is not suitable for outputting augmented reality content from a UX point of view according to the area, shape, and internal object arrangement environment of the target space. It can be flexibly set according to the area, shape, and internal arrangement of the target space.

The target object selection unit 130 is based on whether the coordinates of each position in which the plurality of objects are located are included in either the output area 330 of the augmented reality content or the non-output area 331 of the augmented reality content on the display. It can be determined by object location information. Here, when the location coordinates of the object are included in the non-output area 331 of the augmented reality content, it may be excluded from selection of the target object as the minimum satisfactory value is not satisfied.

3D is an exemplary diagram for explaining a process of calculating movement speed information of a plurality of objects according to an embodiment of the present invention. Referring to FIG. 3D, the target object selection unit 130 may calculate object movement speed information based on a change in position coordinates at which a plurality of objects are located for a predetermined time.

For example, when augmented reality content is mapped to an object with a high moving speed, it is difficult for the viewer to recognize the augmented reality content, and dizziness may be felt by the augmentation of the augmented reality content. Here, the smaller the movement speed value of the target object, the higher the probability of being selected as the target object. When the movement speed value exceeds the threshold value, the target object may be excluded from the selection of the target object as the minimum satisfactory value is not satisfied.

For example, the target object selection unit 130 moves the moving speed of the A1 object 301 among the A fish species 301-303: 0.5m/min (341), the moving speed of the A2 object 302: 1.2m/min (342), the moving speed of the A3 object 303: It can be calculated as 5m/min (343). For another example, the target object selection unit 130 moves the moving speed of the B1 object 311 among the B fish species 311 to 313: 3.2m/min (344), the moving speed of the B2 object 312: 10m/min (345), the moving speed of the B3 object 313: 0.8m/min (346).

In addition, the target object selection unit 130 may calculate object movement speed change amount information using Equation 1 below.

Referring to Equation 1, the target object selection unit 130 may calculate the object movement speed change amount information by calculating an absolute value of the speed change amount of the object in the target space for a predetermined time (eg, n minutes).

In this case, the measurement end time may be set by the administrator in consideration of the respective running time of the augmented reality content, the service domain, and other exhibition viewing conditions.

When the target object selection unit 130 maps the augmented reality content to an object with a rapid change in speed, a gap may occur between the location coordinates of the object and the location coordinates at which the augmented reality content is output. It can be difficult to do.

Therefore, the smaller the absolute value of the object movement speed change amount information, the higher the probability of selection of the target object may increase.If the object movement speed change amount exceeds the threshold value, the target object will be excluded from selection as the minimum satisfactory value is not satisfied. I can.

3E is an exemplary diagram showing a minimum satisfactory value and a weight considered to select a target object according to an embodiment of the present invention. Referring to FIG. 3E, the target object selection unit 130 is based on the minimum satisfaction value and weight assigned to each of the target object selection condition information according to the domain of the service providing the augmented reality content and the service provision situation. You can select an object to map content to.

The minimum satisfactory value 356 may be set for object position information 353 on the display, object movement speed information 354, and object movement speed change amount information 355 among target object selection condition information.

The weight 357 is to be set for the linear distance information 351 between the display and the object, the object area area information 352, the object movement speed information 354, and the object movement speed change amount information 355 among the target object selection condition information. I can.

3F is an exemplary diagram for explaining a process of selecting a target object by reflecting a minimum satisfaction value and a weight according to an embodiment of the present invention. Referring to FIG. 3F, for each item included in the target object selection condition, a minimum satisfactory value 356 and a weight 357 may be set.

For example, a minimum satisfying value 356: less than 2m, weight 357: 5 is set for the linear distance information 351 between the display and the object, and the minimum satisfying value 356 for the object area area information 352 ): 0.3m ² , weight (357): 3 is set, and the minimum satisfactory value 356 for object location information 353 on the display: augmented reality content non-output area (x<200, y<350) is set And, for the object movement speed information 354, a minimum satisfying value 356: less than 5/min, a weight 357: 2 is set, and for the object movement speed change amount information 355, a minimum satisfying value 356: Less than 2m/min, weight 357: 2 may be set.

The target object selection unit 130 may determine whether a minimum satisfactory value is satisfied for a plurality of objects. In this case, an object whose minimum satisfactory value is not satisfied may be excluded from the candidate target object.

For example, the target object selection unit 130, the object 2 (362) does not meet the minimum satisfactory value of the linear distance information 351 between the display and the object, and the object 3 (363) is the object position information 353 on the display. Since the minimum satisfactory value of is not satisfied, the object 2 362 and the object 3 363 may be excluded 370 from the candidate target object.

Thereafter, the target object selection unit 130 may calculate a degree of suitability for the target object based on the weight 357.

Referring to Equation 2, the target object selection unit 130 may calculate a fitness by calculating a predetermined weight and a normalized target object selection condition as a first-order polynomial. In this case, when the target object selection unit 130 shows a better result as the value decreases, such as linear distance information 351 between the display and the object, object movement speed information 354, and object movement speed change amount information 355, Goodness of fit can be calculated with '1-(normalized value)'.

For example, the target object selection unit 130 calculates the fitness of object 1 (361) as '2.2608' and the fitness of object 4 (364) as '0.9975', so that'object 1'(361) is the final target. It can be selected as an object 371.

Returning to FIG. 1 again, the providing unit 140 may transmit reference information on the selected target object to a content providing server (not shown), and receive augmented reality content for the target object from the content providing server (not shown). have.

The display unit 150 may display the augmented reality content for the target object provided to be overlaid on the target space through the smart display. A process of displaying an augmented reality content for a target object through a smart display will be described in detail with reference to FIG. 4.

4 is an exemplary diagram for explaining a process of displaying an augmented reality content for a target object through a smart display according to an embodiment of the present invention. 2 and 4, when the'A3 object' 401 is selected as the target object of the species A, the augmented reality content 410 for the species A is a location corresponding to the location of the'A3 object' 401 It can be displayed by overlaying it on. In addition, when the'B3 object' 402 is selected as the target object of the species B, the augmented reality content 411 for the species B may be displayed by overlaying the location corresponding to the location of the'B3 object' 402. .

Through this process, the spectator 400 does not feel dizziness in recognizing the augmented augmented reality content for an aquatic animal having mobility, and it may provide an advantage of not feeling dizzy or uncomfortable in recognizing necessary information.

The augmented reality content providing apparatus 100 may be executed by a computer program stored in a medium including a sequence of instructions for providing augmented reality content through a smart display. When executed by a computing device, a computer program captures a target space located inside the smart display through a camera, analyzes a plurality of objects located in the target space from the captured image, and analyzes each object required for the creation of augmented reality content.
