1 shows a system block diagram of a mobile device for performing a method for generating an augmented reality object according to an embodiment of the present invention, and FIG. 2 is a method for generating an augmented reality object according to an embodiment of the present invention. It shows a flow chart.

A method of generating an augmented reality object by a mobile device according to an embodiment of the present invention includes collecting a two-dimensional image through an image collection unit of the mobile device (S110).

For example, the mobile device may be a smartphone, tablet computer, or the like equipped with a camera. A method in which a user arbitrarily draws a picture on paper and photographs the drawn picture with a camera may be exemplified. Arbitrarily drawn pictures obtained by camera shooting may be collected as a two-dimensional image, but the method of collecting the two-dimensional image is not limited thereto. For example, in the case of a mobile device having a touch screen, such as a smart phone or tablet computer, the 2D image can be collected by directly drawing the 2D image on the touch screen of the mobile device.

In this case, the 2D image may be a closed curve or a curve expressed within the closed curve. Here, the closed curve refers to a curve that starts from one set of points and returns to the starting point by moving in one direction, and may be understood to include a polygon or a circle such as a triangle, a quadrangle, or a pentagon. In the case of a closed curve, the inside and outside of the closed curve determined by the 2D image editing unit may be defined as distinct from each other.

If the 2D image is a curve expressed in a closed curve, the 2D image editing unit may further include defining a third closed curve including a line segment connecting both ends of the curve using the curve. For example, when drawing an animal's head and describing the eyes, nose, mouth, etc. on the head, only a line can be displayed, but the line at this time can be expressed as a curve with a gentle curvature rather than a straight line or segment. In the embodiment of the present invention, both ends of this curve are defined as a third closed curve including one line segment, so that when performing an operation input through a user's arbitrary dragging, which will be described later, it is treated as one object and an operation image is expressed. may be provided to do so.

Next, the plane containing the 2D image is defined as the x-y plane of the 3D coordinate system through the 3D image editing unit of the mobile device, and the 2D image is extended to an arbitrary height in the z-axis direction perpendicular to the x-y plane to create a 3D image. and generating a dimensional image (S120).

For example, when a user draws a 2D image on paper, the 2D image is collected by capturing the drawn plane with the camera of the mobile device. is defined as

The 3D image editing unit defines the z-axis in the direction perpendicular to the x-y plane, and allows the 2D image to rise to a height predefined by the user, thereby creating a 3D image shape that conveys a three-dimensional effect.

However, the 2D image does not rise or fall along the z-axis including the boundary of the 2D image, but moves from the boundary to the inside of the closed curve constituting the 2D image, and the 2D image rises and extends to transform into a 3D image with a three-dimensional effect. can be exemplified. For example, when a dog shape is drawn on paper on the floor and collected through a camera of a mobile device, a three-dimensional image in which the dog's body appears to have a certain sense of volume can be created. In this case, the 3D image may be expressed as having both positive and negative values on the z-axis symmetrically on the x-y plane. It may be provided to generate a three-dimensional image having a sense of volume by extending the surface in a negative direction as well as having a sense of volume only in the positive direction of the z-axis based on the x-y plane. Through this, even if the augmented reality object created through the embodiment of the present invention is viewed from the opposite direction of 180 degrees relative to the z-axis, it can be seen as a three-dimensional image shape having a three-dimensional effect.

Meanwhile, the generating of the 3D image may further include collecting plane rotation information of the x-y plane through the touch screen so that the x-y plane forms a predetermined angle with the touch screen.

The user can redefine the x-y plane by rotating the x-y plane so that it appears inclined at a certain angle when checked through the touch screen, unlike the state in which the x-y plane is initially collected through the touch screen of the mobile device. In this case, the z-axis also changes by the change in inclination of the newly defined x-y plane.

Next, selecting an arbitrary coordinate on the surface of the 3D image by touching the touch screen of the mobile device (S130).

A 3D image to which a three-dimensional effect is imparted is displayed on the touch screen of the mobile device, and this may be displayed as having a boundary and a surface distinguished from the surrounding background. Arbitrary coordinates are selected by touching an arbitrary point on the surface of the 3D image. For example, by touching the end of the leg of the 3D image of the puppy displayed on the touch screen of the mobile device, the coordinates of the end of the leg may be selected.

Next, the motion information editing unit of the mobile device includes a step of setting a predetermined range of motion around an arbitrary coordinate of the surface of the 3D image (S140).

In this step, it is specified that the 3D image can be deformed only within a range within a circular range based on an arbitrary coordinate selected from the surface of the 3D image or within a range of a closed curve designated by the user.

The center of the 3D coordinate system including the x-y plane and the z-axis may be the coordinates of the center of gravity on the x-y plane of the 2D image. In a state in which the 3D image is fixed based on the coordinates of the center of gravity of the overall shape, only a specific portion with a designated movable range around an arbitrary coordinate can be designated as a movable range.

Alternatively, the predetermined range of motion may be the entire 3D image or a part of the 3D image within a preset range from arbitrary coordinates. That is, when the 3D image is designated as moving as a whole, the movable range may change together with a change as much as the amount of change in coordinates of the entire 3D image.

Meanwhile, the 3D image editing unit may further include extracting coordinates of the center of gravity on the x-y plane and touch coordinates on the x-y plane of arbitrary coordinates from the closed curve constituting the 2-dimensional image. Through this, by pre-calculating the amount of change in touch coordinates according to the amount of change in the center of gravity coordinates, it is possible to calculate the overall movement coordinates of the 3D image surface with a designated movable range even with small resources of the mobile device.

For example, if the arbitrary coordinates selected in the previous step are the tip of the dog's leg, the dynamic information editing unit moves the range of motion corresponding to the range of movement of the dog's legs only within a certain range around the arbitrary coordinates. range can be given. If the three-dimensional image of the dog shape is preset to move from the right to the left, the movement range that has already been assigned according to the amount of change in the center of gravity can be changed and the movement can be performed.

Regarding the above-described movable range, the predetermined movable range is the case where a virtual first tangent line in contact with the contour of the two-dimensional image and a continuous third tangent line intersect at a preset angle, and the third tangent line is in contact with the contour line. The contact point can be set to the center of the movable range. For example, the outline of a dog-shaped 2D image may be expressed as a curve having a constant curvature unless it is a straight line segment. In this case, when a change in slope of a continuous tangent line of the image contour is detected, natural movement of the object can be expressed by designating this as the center of the movable range.

To this end, the step of collecting the 2D image may further include extracting the outline of the 2D object distinguished from the surrounding map from the 2D image collected through the image collection unit through the 2D image editing unit of the mobile device. . In this case, the 2D image editing unit may extract the outline of the 2D object through any one or more of contour detection algorithms composed of a Sobel function, a Laplacian function, and a Canny function.

The Sobel function can be defined as an algorithm that performs partial differentiation in the x and y directions (differentiation only for one character) in order to obtain the gradient with the difference between adjacent pixels, and returns the resulting image by setting the kernel size, ratio, offset, etc. The Laplacian function is a function that allows you to determine whether the contour line has occurred in a bright area or a dark area in the form of a second order differential. It can be defined as an algorithm that outputs the resulting image after doing so. The Canny function is an improved algorithm of the Laplacian function. After the first differentiation, vector differentiation is performed in four directions, and the points having the maximum values in the result become contours. In the case of using the Canny function, the contour line can be detected more accurately by setting the upper and lower threshold values.

Next, a step of inputting time-sequential coordinates through continuous dragging around an arbitrary coordinate through the touch screen unit (S150).

A user selects an arbitrary coordinate of a 3D image displayed on a touch screen unit of a mobile device, and then designates an operation he/she wants to give. For example, by dragging a finger left and right while touching the tip of the dog's leg designated in the previous step, a trajectory for performing repetitive walking motions left and right so that the tip of the leg moves may be input.

Next, the 3D image editing unit includes a step of generating motion information that can be expressed as the surface of a predetermined 3D image in which the motion range is set changes along with changes in time-series coordinates (S160).

In this step, it can be understood that not only the selected coordinate point of the surface of the 3D image, but also the surface inside the surrounding closed curve changes along with the change of time-series coordinates. According to the change of the previously set time-sequential coordinates, the surface of the 3D image inside the 3D image, which is divided into the surface and the outline of the previously selected 3D image, also changes according to the change of the time-sequential coordinates, thereby moving a specific part of the 3D image. can express

At this time, the 2D image editing unit of the mobile device determines whether the collected image corresponds to an object on pre-stored data or transmits it to a third service server to receive information related to an everyday object most similar to a closed curve represented by an outline It may be provided to naturally express the appearance according to the change of the outline of the object. For example, if the outline of the 2D image is a four-legged dog with a tail, the 2D image editing unit of the mobile device or the third service server defines the boundaries of the head, legs, and tail based on the outline information and draws the legs. The movement expressed by dragging can be applied together with the change of the rest of the outline to express natural movement.

To this end, the 2D image editing unit creates joint information of an object (animal), and when designating and dragging a specific part of an animal, the joint information of the selected specific part or other parts that change according to the movement of joints within a certain area from the specific part. , and apply the change amount of the joint to the change of the outline so that natural motion can be expressed.

In the present specification and drawings, preferred embodiments of the present invention are disclosed, and although specific terms are used, they are only used in a general sense to easily describe the technical content of the present invention and help understanding of the present invention, It is not intended to limit the scope. It is obvious to those skilled in the art that other modifications based on the technical idea of the present invention can be implemented in addition to the embodiments disclosed herein.
