Here, the cube image may be provided through a scan device, a drawing device, or a camera device of a user device provided to enable data transmission and reception with the transceiver 140 of the service server 100. For example, in the case of webtoons, the images drawn by the artist are used by the artist, so that the finished images can be used through the drawing device. Or you can use the cube image taken by the camera. That is, the developed view may be generated using a camera provided to photograph the interior through an incision formed on one surface of the cube formed by using the cube image.

Figure 5 is a VR webtoon learning image providing method according to an embodiment of the present invention, a VR camera and a cube image provided to transmit the VR image, a cube image is attached to the structure that can form a three-dimensional cube attached It is shown.

Referring to FIG. 5, a structure constituting a three-dimensional cube and a VR camera located therein are provided. In this case, when the developed view provided to wrap the cube is attached to each surface of the cube, the VR camera can collect the surrounding images. Through such a principle, each image of the developed view constituting the cube through the VR camera can be converted into a drawing image. Next, the method for providing a VR webtoon learning image according to an embodiment of the present invention includes a service server 100. Generating a two-dimensional distorted image by converting the developed view so that the distorted image generating unit 120 of FIG. 1 becomes an image in a 360 degree direction based on one direction viewed from the center of the three-dimensional space.
