2 3 Method and device for deforming a template model to create animation of 3D character from a 2D character image

摘要

The present invention relates to a method to convert two-dimensional (2D) character picture data into a three-dimensional (3D) model to be animated as well as allowing a general user to easily create a 3D animation with only one sheet of a 2D character picture. According to the present invention, the method comprises: a step of reading the 2D character picture data through machine training to recognize a main joint of a 2D character, and to understand the position and size of a skeleton; a matching step of matching the main joint recognized from the 2D character picture data with a main joint of a rigged 3D template model; a skeleton modification step of modifying for each bone the 3D template model where the main joint is matched in accordance with the recognized position and size of the skeleton; a silhouette modification step of modifying mesh data forming the 3D template model in accordance with a silhouette of the 2D character picture data; and a step of generating a texture of front and rear surfaces of the modified 3D template model.
