Description

TECHNICAL FIELD [0001] The present invention relates to a data processing method for a reactive type augmented reality card game by collision check of a virtual object, and a responsive augmented reality card game device for playing augmented reality card game}

The present invention relates to a data processing method for a reactive type augmented reality card game and a reactive type augmented reality game play device, and more particularly, And to a reactive type augmented reality card game play apparatus.

Augmented Reality (AR) is a kind of Mixed Reality which is a real and virtual domain. It is a combination of virtual information and real information to enhance information of object, image or image. It is also referred to as extended reality in terms of extending human perception and perception of things by adding additional virtual information to actual information.

Recently, thanks to the proliferation of mobile devices equipped with cameras such as smart phones and tablet computers, augmented reality technology has been expanded to include mobile devices, and various sensor parts for detecting position, direction and inclination of GPS, etc., In this paper, we propose a mobile augmented reality system based on portable mobile devices, which can realize augmented reality by sensing the position, height and direction of a real object using a mobile device.

On the other hand, a card game in which a character appearing in a game and a capacity variable of the character are determined according to a card obtained from each player offline, and a battle game is performed according to a predetermined game rule using the game, , The physical ability, attack power, defense power, and the like are set and used as attributes of the character who proceeds the battle.

The battle game using the above card is still being played as a purely traditional offline card game, and it is implemented in a form of linking with a dedicated game machine, a personal computer, a smart device and a dedicated game server according to the development of IT technology.

In particular, technology and game contents that combine augmented reality technology through a mobile device equipped with a camera and a game using a card are being tried.

 In such augmented reality technology, a technique of recognizing a plurality of markers mainly by recognizing each of the markers, and synthesizing the virtual objects corresponding to the recognized markers independently at the positions of the respective markers is generally used. A technique of performing a virtual-object interaction that recognizes and reacts to the distance between markers when one of the markers enters a predetermined distance from another marker can be used.

As a result, the mutual action of the virtual objects is defined in advance according to the inclination, direction, distance, and type (ID) between the markers printed on each card, and the inclination, direction A method of implementing an interaction using a plurality of markers printed on a card by implementing an augmented reality apparatus and method expressing an operation of a virtual object defined in advance according to a type of a marker (ID) when the distance is changed .

In the technique of the following patent document, in a manner of defining a new marker based on the relative position (slope, direction, distance) between the markers printed on the two cards, Lt; / RTI >

However, in the case of the following patent document, since the situation is set in such a manner that animation is assigned by a new marker defined according to the relative position of the printed marker, setting or resetting the game situation by various variables, There is a limited problem.

In other words, when applied to a card battle game, an animation is assigned according to the relative position of the marker, so that the result value is already determined. Therefore, in addition to the animation, It is impossible to process the animation data dynamically according to the setting or the resetting and the change thereof. Therefore, there is a technical limitation to apply to the game which needs various game situation presentation.

In addition, since a new marker is defined according to a situation according to the relative position of each marker and each animation is defined, the number of markers to be printed is increased as the type of the card increases. The number of new markers and animation also increases.

For example, if the number of the markers printed on the card is 10, and the relative position of the markers printed on the two cards is recognized, the number of newly recognized markers and the number of animations allocated to the markers increases by 90.

With the increase in the number of markers to be newly recognized and the increase in the number of animations allocated thereto, the load of the device for processing the augmented reality and the data to be processed increase sharply in the case of the above technique, There is a problem that is not suitable for a limited mobile device.

In addition, a new marker is defined according to the relative position of the markers, and when the relative position values of the plurality of recognized markers, that is, the conditions of angle, distance, and direction do not exactly coincide with each other, There is a problem that the recognition rate is lowered. Especially, when applied to a card battle game in which cards are frequently overlapped, a problem that a new marker itself is not recognized due to image deformation due to overlaps of markers during game play frequently occurs.

Accordingly, it is not possible to apply the above-described conventional technology to a card battle game, and it is a technique to combine the augmented reality technology and the card battle game. As a technique, the interaction operation between the characters synthesized and displayed in the augmented reality processing device is efficiently processed New technologies are urgently required.

The collision detection step S160 is performed by the animation control unit 60 of FIG. 4 as a process of determining whether the end point of the ray is in contact with the area of the collision object of the 3D virtual object of the character of the other card.

In the animation execution step S170, the augmented reality processing unit 250 of FIG. 4 executes the animation by calling and executing a predetermined animation for the 3D virtual object of the character under the control of the animation control unit 60 of FIG. In the collision detection step (S160), when it is determined that the end point of the ray is in contact with the area of the collision object of the 3D virtual object of the character of the other card, a predetermined animation is called and executed to map .

The play time of the animation is determined by calling the ability variable of the character of the other card when the end point of the animation is judged to be in contact with the collision object of the 3D virtual object of the character of the other card, Time can be determined.

For example, if the ability variable of the character of the other card is a fitness variable, and if the ability variable of the character is an attack variable, the attack variable of the ability variable of the character of the other card is preset in the fitness variable of the capacity variable of the character of the other card And the animation is executed until the subtracted fitness variable value is equal to or greater than a predetermined value. In the case of the present embodiment, the predetermined value is implemented as 0 by executing the animation until the subtracted fitness variable becomes zero.

On the other hand, the predetermined damage variable value, namely, the attack power / Sec, is increased or decreased by comparing the attribute of the character of the card, for example, water, fire, wind and the character of the other card, The amount of time-off of the stamina variable can be adjusted.

For example, when the attribute of the character of the card playing the attack animation is higher than the attribute of the other card, the attack power variable value that is subtracted per hour, that is, the attack power / Sec is increased so that the short-time attack animation is played. The attack power / Sec is reduced, and as a result, the long-time attack animation is played.

The priority of the attribute is set in advance in the order of, for example, fire <fire <fire <fire> ... and stored in the electronic device.

According to an embodiment of the present invention, the attack power variable of the ability variable of the character is reduced by a predetermined time when the attribute of the character of the card is not dominant, The execution time of the animation can be preset or adjusted in various ways using the capability variable value and the attribute.

As described above, the play time of the animation of the character can be determined by comparing the fitness variable such as the fitness variable of the other card or the damage variable of the card.

When applied to a battle game, in the animation execution step (S170), when it is determined that the end point of the ray is in contact with a collision object of a 3D virtual object of a character of another card, the animation called and executed is indicative of an attack operation of the character Animation can be used.

Hereinafter, a concrete implementation method of a data processing method of a reactive type augmented reality card game by collision check of virtual objects according to the present invention will be described with reference to embodiments of the drawings described later.

FIG. 4 is a block diagram of a reaction type augmented reality card game play device of the present invention, and FIG. 5 is a block diagram of a case in which a reaction type augmented reality card game play device of the present invention is implemented as a portable electronic device such as a smart device.

The data processing method of a reactive type augmented reality card game by collision check of a virtual object of the present invention is implemented by the reactive type augmented reality card game play device of Fig. 4, and the system of Fig. 4 is implemented by a portable electronic device such as a smart device .

Referring to FIG. 4, the reaction type augmented reality card game play device 200 of the present invention basically performs an interaction between 3D virtual objects by collision check of the virtual objects in an electronic device including a photographing device and a display such as a camera And includes an imaging device control unit 210, a card image detection unit 220, a card recognition unit 230, a card tracking unit 240, an augmented reality processing unit 250, and an animation control unit 260, A DB 231, a character DB 251, and an animation DB 261.

The photographing apparatus control section 210 controls the photographing apparatus to photograph an image including one or more cards and to generate and output a photographing image of one or more photographed cards.

 The card image detecting unit 220 processes the captured image of the at least one card to detect and output the card image and the image printed on the card, extracts at least one card image from the captured image, excluding the background, (230).

The card recognition unit 230 recognizes the type of the card by searching the card DB 231 stored in advance for the detected card image and outputs the card information. (Card 1, card 2, card 3, ....) stored in association with the identifier of the corresponding card in the card DB 231 and outputting information of the card having the extracted card image In the method of comparing the stored image with the extracted card image, the feature points of the extracted card image are extracted and the feature points of the card image are stored in association with the identification information of the corresponding card on the card, 1, card 2, card 3, ....). The process of extracting the feature points of the image and determining the identity is implemented according to various conventional image recognition methods.

The card tracking unit 240 processes the detected card image in real time and calculates and outputs the detected position information of the card to track the position of the card. The position information includes information on the position and direction of each card. In the tracking method, the position of each card is tracked by calculating the three-dimensional position value (x, y, z value) of one or more cards. The changed position information is transmitted to the augmented reality processing unit 250 in real time.

The calculation of the three-dimensional position value may be performed by comparing the color values of each pixel of the card image, or by comparing the feature points, or by changing values thereof, or by changing the characteristic of the card having a rectangular shape in which a typical shape, The outline of the card image that has been extracted and recognized can be extracted and the shape of the card, for example, a shape of a rectangle of a previously stored card, can be compared and calculated.

It is also possible to use only the feature point information of the card image without using the entire card image as the target even in tracking the card position change. In addition, according to an embodiment, the card position information includes the recognized card slope value calculated from the three-dimensional position value, in addition to the three-dimensional position value of the card calculated from the card image, .

The calculation of the slope value may be performed by comparing the color values of respective pixels of the card image, by comparing the feature points, or by changing values thereof, or by considering characteristics of a card having a typical shape, for example, The outline of the extracted card image can be extracted and the inclination value can be calculated through comparison with the rectangle shape of the card stored in advance.

The extracted printed whole image or the image of the character printed on the card may be extracted and used as a card image, and only the outline of the card image may be used. Considering the characteristics of a card having a typical shape, for example, a shape of a rectangle having a predetermined size and shape in advance, it is advantageous to use the outline of the card image extracted and recognized to recognize one or more of the card positions or directions, It is more preferable because it improves the recognition accuracy and reduces the load to be used.

The augmented reality processing unit 250 calls the 3D virtual object of the character assigned to the card from the character DB 251 according to the card information output from the card recognition unit 230 and transmits the 3D virtual object of the called character to the card According to the card position information output from the tracking unit 240, the composite image of the character is mapped on the photographed image of the card and is transmitted to the display unit. The display unit displays the augmented reality image of the character in which the 3D virtual object of the character is synthesized in the shot image.

In the present embodiment, a physical strength variable is used as a capacity variable of a character of another card, and an ability variable of the character is used as an attack variable to determine a play time of the animation. Etc.) is taken into consideration, and an animation which is called and executed is used to indicate an attacking operation of the character.

In the present embodiment, if the ability variable of the character of the other card is a physical fitness variable, and if the ability variable of the character is an attack power variable, the attack variable of the character's ability variable in the physical fitness variable of the character of the other card is And the animation is executed until the subtracted fitness variable value is equal to or greater than a predetermined value. In the case of the present embodiment, the animation is executed until the subtracted fitness variable becomes 0, and the preset value is 0.

Here, the predetermined value of the attack power variable, i.e., the attack power / Sec, is increased or decreased by comparing the attribute of the card's character, for example, water, fire, Can be adjusted.

For example, when the attribute of the character of the card playing the attack animation is higher than the attribute of the other card, the attack power variable value that is subtracted per hour, that is, the attack power / Sec is increased so that the short-time attack animation is played. The attack power / Sec is reduced, and as a result, the long-time attack animation is played.

According to an embodiment of the present invention, the attacking variable of the ability variable of the character is deducted by a predetermined time when the attribute of the character of the card is not superior, and the animation is repeated until the value of the subtracted attacking variable is equal to or greater than a predetermined value It can also be executed.

As described above, the play time of the animation of the character is determined by comparing the fitness variable such as the physical strength variable of the other card or the damage variable of the card, thereby maximizing the game element.

Referring to FIG. 11, in the present embodiment, when the augmented reality image of the character is displayed in the step of displaying the augmented reality image (S140) of the character, and the object and the ray are set in the object and the ray setting step S150, A wait motion animation is executed on the 3D virtual object. Depending on the embodiment, the execution of the atmospheric motion animation may be replaced by a persistent representation of the augmented reality image of the 3D virtual object.

The collision detection repeatedly performs a collision detection method for determining whether the end point of the straight line of the ray is in contact with the area of the collision object of the 3D virtual object of the character of the other card in the collision detection step (S160).

Then, when the collision is detected, the 3D virtual object of the character is changed to the attack state, and an animation (attack Ani) for displaying the attacking action of the character is executed, and the attack variable of the character per hour (Attacking power / Sec) is subtracted every second, and continues until the fitness variable of the opponent reaches 0, and when the fitness variable of the opponent reaches 0, the 3D virtual object of the character is changed to the stop state to display the attacking action The animation (attack Ani) is stopped, and the animation of the stop state is played. Then, the designated animation (for example, animation showing the victory) is played once and then ended. In this case, the character of the card in the battle game is displayed as winning.

If the value of the attack power variable of the character per hour of the card (attack power / Sec) is subtracted every second from the fitness variable of the opponent character, the process further comprises checking the opponent's attribute, When the attribute is superior to the opponent's attribute, the value of the attack variable of the character per hour of the character of the card (attack power / Sec) is increased and consequently the execution time of the animation (attack Ani) If the attribute of the card is not superior to the opponent's attribute, the value of the attack power variable of the character per hour (attack power / Sec) decreases, and as a result, the execution time of the animation (attack Ani) .
