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.
