The present invention provides a method of generating a pseudo-3D
user-adapted avatar by using artificial intelligence based on a method of
converting a 2D image to the pseudo-3D image having visual and partial
functions of a 3D model, and a method of performing a coordination
simulation by applying the pseudo-3D coordination image generated by
applying total clothes coordination information derived from the
artificial intelligence to a user-adapted avatar. The pseudo-3D
user-adapted avatar is generated by receiving primary size information
and deriving secondary size information from an algorithm by using the
primary size information. The pseudo-3D user-adapted avatar image
suitable to the user's body shape is generated from the 2D standard
avatar image. The pseudo-3D coordination image is generated, from the
standard 2D image by using coordination-related information, by an
artificial intelligence algorithm, and in response to a corrected
pseudo-3D user-adapted avatar image, the generated pseudo-3D coordination
image is displayed.
