摘要： Disclosed herein are an apparatus and method for creating animation by capturing the motions of a non-rigid object. The apparatus includes a geometry mesh reconstruction unit, a motion capture unit, and a content creation unit. The geometry mesh reconstruction unit receives moving images captured by a plurality of cameras, and generates a reconstruction mesh set for each frame. The motion capture unit generates mesh graph sets for the reconstruction mesh set and generates motion data, including motion information, using the mesh graph sets. The content creation unit creates three-dimensional (3D) content for a non-rigid object by generating a final transformation mesh set, having a topology similar to that of the reconstruction mesh set, using the motion data.

摘要： Provided are system and method for generating a 3D facial model and animation using one video camera. The system includes a pre-processing part, a facial model generating part, a transferring part, a projecting part, an error calculating part, and a mesh transforming part. The pre-processing part sets correspondence relations with other meshes, generates an average 3D facial model, and generates a geometrical model and a texture dispersion model. The facial model generating part projects the average 3D facial onto an expressionless facial image frame that stares a front side to generate a performer's 3D facial model. The transferring part transfers a 3D facial model template having an animation-controlled model to the performer's 3D facial model to generate the performer's 3D facial model. The projecting part projects the performer's 3D facial model onto a facial animation video frame including a facial expression. The error calculating part calculates an error projected by the projecting part. The mesh transforming part moves or rotationally converts a joint in such a direction as to minimize the error.

摘要： A method for creating a 3D face model by using multi-view image information, includes: creating a mesh structure for expressing an appearance of a 3D face model by using a first multi-view image obtained by capturing an expressionless face of a performer; and locating joints of a hierarchical structure in the mesh structure, by using a second multi-view image obtained by capturing an expression performance of the performer. Further, the method includes creating a 3D face model that is animated to enable reproduction of a natural expression of the performer, by setting dependency between the joints and the mesh structure.
