1. A hologram generation device enabling two-way interaction comprising:
a hologram object generation unit for generating a hologram target object composed of planar component bodies in an exploded view in which a plurality of canvases and a 3D object which form a screen area of a flat display panel are exploded in each of at least three directions;
a hologram generation unit for generating a three-dimensional hologram of the 3D object by outputting the hologram target object through the flat display panel toward reflective surfaces, respectively, corresponding to the at least three directions; and
an interaction providing unit for providing two-way interaction with the three-dimensional hologram in connection with a user terminal,
wherein the hologram object generation unit performs the steps of generating at least one central canvas and left and right canvases symmetrically formed on both sides of the central canvas in an exploded view;
arranging a first center of each planar component body and a second center of a circle inscribed in each canvas to match each other in a process of arranging planar component bodies on each of the central canvas and the left and right canvases, respectively;
moving the first center downward by a predetermined distance when the horizontal length of the 3D object is greater than the vertical length thereof, or moving the first center upward by a predetermined distance when the vertical length of the 3D object is greater than the horizontal length thereof, with respect to the planar component bodies disposed in the central canvas; and
enlarging the sizes of the planar component bodies in a boundary direction of the central canvas based on the first center.
