Hereinafter, an operation of the server 150 generating a virtual space based on the real space image captured by the first electronic device 110 will be described.

According to an embodiment of the present invention, the server 150 may convert an image in real space captured by the first electronic device 110 into a 3D image. The server 150 extracts 3D coordinates based on the real space image photographed by the first electronic device 110 to obtain a 3D image. Dimensional Cartesian coordinates and spatial rotation angle variables that rotate around the x-axis, spatial rotation angles that rotate around the y-axis, and rotation angle variables that rotate around the z-axis include xr, yr, and zr, respectively.

The server 150 has various detailed functions for extracting each 3D coordinate from the real space image captured by the first electronic device 110 , which will be described later.

According to an embodiment of the present invention, the server 150 may reflect the 3D coordinates in the 3D image by directly applying the extracted 3D coordinates to the real space image photographed by the first electronic device 110 . The server 150 extracts a face, an edge, and a corner from the 3D image, respectively, and may extract the relative positions of these faces, edges, and corners.

The server 150 first extracts the uniform area occupied by the 3D image, and extracts the rapidly changing gray level area from the uniform area. In terms of color and gray level, a region having a uniform area has a high probability of constituting a surface, and the edge, which is an edge of such a surface, is formed to be very narrow and long at the same time as the color and gray level of the surface change rapidly. can figure out An edge is an area where an edge meets an edge, and the gray level tends to darkly converge around the edge, and the probability of a color change around this area is relatively high.

The server 150 may calculate the scale for each part of the virtual space by calculating the area of the surface and the length of the corner in the extracted 3D image, respectively. The server 150 may calculate the continuous length of the edge, calculate the size of the region forming the surface where the edge meets the edge, and measure the overall scale.

According to an embodiment of the present invention, the measurement of the scale calculates the distance of the focused area through perspective recognition from the position where the camera of the first electronic device 110 is located, By comparing the relative ratios, the yarn length of the edge and the yarn area of the face are statistically calculated.

The server 150 calculates the mutually relative directions of each of the extracted faces and edges. This means that when the user touches the virtual space on the first electronic device 110 and drags it in various directions, all the faces, edges, and corners of all areas are combined together.

The server 150 may store not only the 3D image of the virtual space, but also 3D coordinate information on the 3D image, and the user may use the first electronic device 110 at different places and times. Thus, the virtual space can be requested to the server 150 .

Meanwhile, according to an embodiment of the present invention, the server 150 may detect the current location of the user based on the GPS signal and direction information provided from the GPS module and the geomagnetic sensor of the first electronic device 110 . Based on the user's current location, a service area serving the virtual space may be guided. The service area refers to the area where the virtual space is created. By displaying the user's current location and service area on the map so that the service area can be found, the area where the virtual space is not formed and the virtual space are formed can be provided to do so.

According to various embodiments of the present disclosure, the server 150 may receive images captured from a plurality of cameras in a predetermined area installed in a real space as well as a camera mounted on the first electronic device 110 .

In this case, the server 150 may set a plurality of reference points in an arbitrary fixed coordinate system based on three orthogonal coordinate axes from the camera position in a predetermined area installed in real space. Here, the three orthogonal coordinate axes refer to three x, y, and z axes indicating directionality in real space around a camera fixedly installed in a preset area, and an arbitrary fixed coordinate system for the camera with respect to the earth's central coordinate system. In each, the horizontal (horizontal, width, left and right), vertical (height, top, bottom, vertical), and depth (depth, principal) are indicated.

The server 150 may acquire position data of three or more reference points in an arbitrary fixed coordinate system using a measuring instrument such as a total station. The measuring instrument is a measuring instrument that can measure both angle and distance, and according to an embodiment of the present invention, the server 150 measures the positions of a plurality of preset reference points in an arbitrary fixed coordinate system with a tracking function capable of motion estimation. Position data can be obtained by performing measurement with coordinates on coordinates of an arbitrary fixed coordinate system using the measuring instrument.

In order to obtain an actual point value, the server 150 fixes the camera and the tracking sensor node to each other within an arbitrary coordinate system, and then sets the plurality of can recognize the reference point of

That is, by recognizing and storing the position of each reference point in an arbitrary fixed coordinate system from the real space image input through the camera of the first electronic device 110 , pixels included in the entire image area are recognized and stored. Pixel values of reference points may be measured for each image captured for each ball.

In addition, in order to obtain the actual point value, the camera and the tracking sensor node are fixed to each other, and then a number of reference point views must be taken with the camera. It is possible to obtain the location and direction data of the tracking sensor node through , and perform the direction and location calculation of the tracking sensor node based on the fixed coordinate system.

According to an embodiment of the present invention, the tracking sensor node is positioned to face each other at a predetermined interval from the installation position of the camera, and in the present invention, the camera of the first electronic device 110 and the tracking sensor node are fixed to each other A number of all views of reference points installed with the camera of the first electronic device 110 are photographed, and the position and direction of the tracking sensor node that moved together with the camera during shooting is also measured and stored in the tracking function, unlike the above arbitrary fixed coordinate system Like the reference point set in , the measurement of the position and direction of the tracking sensor node is not measured by the tracking function, but is measured on the same arbitrary fixed coordinates through the measuring instrument that measured the position of the reference point.

Hereinafter, an operation in which the server 150 overlaps a virtual object (eg, event item) based on a user's request will be described.

The user may call a predetermined virtual object pre-stored in the server 150 using the first electronic device 110 . The server 150 may provide the virtual object to the first electronic device 110 in response to the call. In this virtual object, not only a three-dimensional image, but also 3D coordinate information such as scale, direction, edge, surface, and corner of the object are recorded together. The 3D coordinate information of the virtual object is linked with the 3D coordinates of the virtual space in the future to become an overlapping standard.

The server 150 may mutually synchronize coordinate information applied to a predetermined virtual object and 3D coordinates of a virtual space. In addition, the server 150 may map coordinate information applied to the virtual object by placing a predetermined virtual object synchronized to 3D coordinates in a virtual space. That is, when the virtual object overlaps on the virtual space displayed on the first electronic device 110 , the same coordinate system and scale unit are applied to the coordinates applied to the virtual object and the 3D coordinates of the virtual space.

Furthermore, the server 150 may allow a predetermined virtual object mapped on a virtual space to move according to a user's discretion by interlocking 3D coordinates with coordinate information applied to the virtual object. In addition, the server 105 may change the size of a predetermined virtual object according to the user's discretion so as to be mapped on the virtual space.

The coordinate information of the virtual object is linked to the 3D coordinates of the virtual space, but unlike the 3D coordinates of the virtual space, in the case of the coordinate information of the virtual object, the scale can be changed large or small according to the user's selection. is made up of functions.

Accordingly, the server 150 can be mapped to the virtual space while changing the scale of a predetermined object by the user's arbitrary selection.

In this case, when the virtual object is changed, the length ratio and angle of each edge and face of the virtual object and their mutual arrangement are not changed. That is, only the scale of the virtual object changes.

The server 150 may cause omnidirectional rotation of a predetermined virtual object according to a user's discretion, so that the rotated object is mapped to the virtual space.

More preferably, when the edge of the virtual object approaches within a predetermined distance from the edge of the virtual space, the server 150 accelerates the edge of the virtual object to the edge of the virtual space, matches it, and temporarily fixes it.
