Abstract: 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.

Abstract: Provided is a camera self-calibration method that calculates a focal length of a fixed zoom lens camera from a correspondence point position between images. In the method, a cost function, which is a function of a focal length, is defined, and a focal length that minimizes the defined cost function is obtained to obtain a focal length that allows 3D recovery results of correspondence points calculated from all image pairs coincide with one another. Therefore, reliability of the calculated focal length can be easily verified, and the focal length of the camera can be stably calculated even when the position of input correspondence point is inaccurately given.
