Description

An apparatus for providing an augmented reality for installing virtual objects in a real space, a method therefor, and a computer-readable recording medium in which a program for performing the method is recorded. in a real space, a method therefor and computer recordable medium storing program to perform the method}

The present invention relates to augmented reality, and more particularly, to an apparatus for providing augmented reality for installing an object in a real space, a method therefor, and a computer-readable recording medium in which a program for performing the method is recorded. will be.

Augmented reality refers to a technology that combines and complements virtual objects and information made with computer technology in the real world. The virtual world with additional information in real time is added to the real world and displayed as a single image. Since it was first used to explain the assembly process of Boeing's aircraft cables in 1990, technical research and development has been carried out around the United States and Japan. As smartphones appeared and became active after the mid-2000s, they began to gain attention as they applied this technology.

While VR (virtual reality) technology allows users to immerse users in a virtual environment created by computer graphics, so that they cannot see the real environment, augmented reality technology mixes virtual objects in the real environment so that users can see it in the real environment. You can receive realistic additional information. For example, it is applied in a variety of fields, such as when going on the road, when you look at the surroundings with a smartphone camera, information such as the location, phone number, and map of nearby stores is displayed in a 3D image, and when you shine the sky, weather information appears. .

Meanwhile, a technology that combines virtual reality and augmented reality is called mixed reality (MR). MR provides a mixture of real and virtual information in a real background, but it has not been commercialized yet because it requires a technology that can process large amounts of data. VR, AR, and MR all have something in common in that they are technologies that enable people to perceive reality by realizing a reality that does not exist. However, there is a difference in that AR is a method of adding virtual information to real reality, and in VR, all fictional situations are presented.

Referring to FIG. 2, first, the control unit 160 may display a plurality of objects selectable through the display unit 140. An example of such a screen is shown in FIG. 3A. For example, the controller 160 may provide a plurality of electric poles of different standards and a plurality of switchgears of different standards through the display unit 140 to be selectable. Accordingly, the user may select an object to be augmented among the plurality of objects through the input unit 130 or the display unit 140. The controller 160 senses a user's selection through the input unit 130 or the display unit 140 in step S110 and selects an object to be augmented. In this case, it is assumed that the'straight line type pole 16M' is selected.

After selecting the object to be augmented, the user may focus on the object, for example, a real space in which the electric pole is to be installed through the camera unit 120 of the augmented reality device 100. Then, the control unit 160 may scan the real space focused through the camera unit 120 in step S120 and recognize a plane on the real space. This recognition is achieved through a cloud point as shown in (B) of FIG. 3.

Subsequently, the control unit 160 activates and displays a selectable plane among planes recognized through the camera unit 120 in step S130. For example, as shown in FIG. 3C, the selectable plane may be displayed by changing the color or shape of a cloud point for a selectable plane among a plurality of cloud points. Accordingly, the user may select a position to install the object to be augmented in the activated plane through one of the input unit 130 and the display unit 140.

The control unit 160 detects the user's selection through any one of the input unit 130 and the display unit 140 in step S140, determines a location to install the virtual object, and synthesizes the object at the location determined in step S150 to display the display unit. Mark through. For example, if the location selected by the user on the screen as shown in FIG. 3C is S, as shown in FIG. 3D, the previously selected object, that is, the electric pole is synthesized and displayed at the corresponding location S.

Meanwhile, according to an embodiment of the present invention, as described above, after synthesizing an object into a real space, various additional functions may be provided. 4 to 7 are screen examples for explaining an additional function performed after synthesizing a virtual object in a real space according to an embodiment of the present invention.

According to an embodiment of the present invention with reference to FIG. 4, a position of a virtual object synthesized in a real space may be modified. The controller 160 may detect a user's selection through any one of the input unit 130 and the display unit 140 and may correct the location of the virtual object. That is, when the controller 160 detects an input for modifying the location of the user's object through any one of the input unit 130 and the display unit 140, the control unit 160 moves the object to the modified position and displays the object through the display unit 140. For example, if an input to move the location of an object selected by the user is input on the screen shown in FIG. 4A, the location of the object may be moved and displayed as shown in FIG. 4B.

According to another embodiment of the present invention with reference to FIG. 5, when an augmented object is actually operable, a corresponding operation is manipulated so that it is possible to determine whether there is interference with a real space. The control unit 160 may perform an operation to open or close an operable virtual object, for example, a door of an open/closer, and simulate whether the door interferes in a real space. That is, the control unit 160 can perform a simulation of opening the door of the switch as shown in (D) of FIG. 5 while the door of the switch is closed, as shown in (c) of FIG. 5, and accordingly, the real space The display may be displayed through the display unit 140 so that the user can recognize whether the door interferes.

According to another embodiment of the present invention with reference to FIG. 6, when an augmented object is actually operable, a corresponding operation is manipulated so that it is possible to determine whether there is interference with a real space. The control unit 160 may perform an operation to open or close an operable virtual object, for example, a door of an open/closer, and simulate whether the door interferes in a real space. That is, the control unit 160 can perform a simulation of opening the door of the switch as shown in (D) of FIG. 5 while the door of the switch is closed, as shown in (c) of FIG. 5, and accordingly, the real space The display may be displayed through the display unit 140 so that the user can recognize whether the door interferes.

According to another embodiment of the present invention with reference to FIG. 7, an angle for a required part of an object in real space may be derived through the augmented protractor object. As shown in FIG. 7, the control unit 160 may install a protractor object P in the real space according to a user's input, and the angle of the required part of the object O1 through the installed protractor object P ( a) can be measured.

According to another embodiment of the present invention with reference to FIG. 7, a length of a required part of an object in real space may be derived through an augmented tape measure object. As shown in (E) and (B) of FIG. 7, the controller 160 may install a tape measure R capable of setting the measurement length in a real space according to a user's input, and the installed tape measure R Through this, when an object is installed in a real space, it is possible to measure whether or not there is interference and a distance from another object.

In addition, according to an embodiment of the present invention, an augmented reality screen displayed through the display unit 140 may be captured and generated as an image file according to a user's selection. In addition, the controller 160 may transmit such an image file to another device through the communication unit 110 according to the user's selection.

Next, a method for providing augmented reality in which a virtual object is installed in a real space according to another embodiment of the present invention will be described. 8 is a flowchart illustrating a method for providing augmented reality in which a virtual object is installed in a real space according to an embodiment of the present invention. 9 is a diagram illustrating a method of deriving a horizontal standard of a virtual object according to an embodiment of the present invention.

First, referring to FIGS. 3 and 8, the control unit 160 may display a plurality of objects selectable through the display unit 140. An example of such a screen is shown in FIG. 3A. For example, the controller 160 may provide a plurality of electric poles of different standards and a plurality of switchgears of different standards through the display unit 140 to be selectable. Accordingly, the user may select an object to be augmented among the plurality of objects through the input unit 130 or the display unit 140. The controller 160 senses a user's selection through the input unit 130 or the display unit 140 in step S210 and selects an object to be augmented. For example, a'straight line pole 16M' may be selected.

When an object is selected, the controller 160 calculates a horizontal standard of the selected object. Here, the horizontal standard of the object means the area of the horizontal plane occupied by the object on the augmented reality. In other words, the horizontal standard of an object represents the area occupied when the object is projected on a plane. These horizontal specifications are obtained from Collider data for the 3D model of the selected object. In order to calculate such a horizontal standard, the controller 160 extracts collider data from the 3D model (OBJ) of the object selected in step S220. Referring to FIG. 9, collider data is a standard for a rectangular parallelepiped shape (COL) that covers all areas occupied by the 3D model (OBJ) of an object. This collider data includes the width (x), length (y) and height (z) of a rectangular parallelepiped shape (COL). Subsequently, the controller 160 calculates the horizontal standard of the object by multiplying the lengths of the horizontal (x) and vertical (y) using the lengths of the horizontal (x) and vertical (y) among the collider data extracted in step S230. do. That is, the horizontal standard of the object becomes the area of the bottom of the rectangular parallelepiped shape (COL). The horizontal dimensions of these objects are used to derive the plane on which the objects can be installed.

Meanwhile, after the user selects an object, the object, for example, a real space in which the electric pole is to be installed may be focused through the camera unit 120 of the augmented reality device 100. Then, the controller 160 may scan an actual space focused through the camera unit 120 in step S240 and recognize a plane on the actual space. This recognition is achieved through a cloud point as shown in (B) of FIG. 3.

Subsequently, the control unit 160 recognizes a plurality of feature points in the image captured by the camera unit 120 in step S250. Here, the feature point is a part in which the color changes rapidly in the image, and the control unit 160 compares the color difference between pixels through the pixel value of each pixel of the image, and determines the part in which the color difference changes by a predetermined value or more. You can select and recognize feature points.

Next, the controller 160 derives coordinates of the plurality of feature points by measuring the distance and depth of the plurality of feature points in step S260. At this time, the controller 160 measures the relative distance between the plurality of feature points and the depth, which is the distance from the focal point or the main point of the camera unit 120, through the 3D sensor of the camera unit 120 to determine the virtual space based on the accumulation of the real space. A coordinate system can be created by applying the accumulation of, and coordinates of feature points can be derived according to the generated coordinate system.

Subsequently, the control unit 160 forms a plurality of planes in which a plurality of feature points are connected based on a coordinate system in step S270, and draws all planes parallel or perpendicular to the ground among the formed planes as candidate planes, Create At this time, the candidate plane is not activated.

Subsequently, the control unit 160 calculates a horizontal standard of each of the plurality of candidate planes included in the candidate plane list in step S280. In this case, the controller 160 may calculate the horizontal standard of the candidate plane by calculating the horizontal and vertical lengths of each candidate plane through a coordinate system.

Next, in step S290, the controller 160 selects a candidate plane whose horizontal standard is larger than the horizontal standard of the object among the plurality of candidate planes and selects a selectable plane.

That is, since an object cannot be constructed on a candidate plane having a horizontal standard smaller than the horizontal standard of the object, a candidate plane having a horizontal standard larger than the horizontal standard of the object is selected as a selectable plane.

Subsequently, the controller 160 activates the selectable plane in step S300 and displays it through the display unit 140. For example, as shown in FIG. 3C, the selectable plane may be displayed by changing the color or shape of a cloud point for a selectable plane among a plurality of cloud points. Accordingly, the user may select a position to install the object to be augmented in the activated plane through one of the input unit 130 and the display unit 140.

The controller 160 detects a user's selection through any one of the input unit 130 and the display unit 140 in step S310, determines a location to install the virtual object, and synthesizes the object at the location determined in step S320 to display the display unit. Mark through. For example, if the location selected by the user on the screen as shown in FIG. 3C is S, as shown in FIG. 3D, the previously selected object, that is, the electric pole, is synthesized and displayed at the corresponding location S.

Meanwhile, the method according to the embodiment of the present invention described above may be implemented in the form of a program that can be read through various computer means and recorded on a computer-readable recording medium. Here, the recording medium may include a program command, a data file, a data structure, or the like alone or in combination. The program instructions recorded on the recording medium may be specially designed and configured for the present invention, or may be known and usable to those skilled in computer software. For example, the recording medium includes magnetic media such as hard disks, floppy disks, and magnetic tapes, optical media such as CD-ROMs and DVDs, and magnetic-optical media such as floptical disks ( magneto-optical media), and hardware devices specially configured to store and execute program instructions such as ROM, RAM, flash memory, and the like. Examples of program instructions may include not only a machine language such as that produced by a compiler but also a high-level language that can be executed by a computer using an interpreter or the like. These hardware devices may be configured to operate as one or more software modules to perform the operation of the present invention, and vice versa.
