Abstract:
A method for capturing a 3D geometric model of an animated 3D object, and color and shading information of a surface of the animated 3D object, the method comprising:capturing a base mesh of the 3D object;capturing n simultaneous video sequences of the animated 3D object with markers applied to the surface of the object from each of n cameras positioned around the 3D object, where n is two or more and the video sequences include n camera images per frame;determining 3D positions of the markers from the n 2D camera images for frames in the video sequence;determining an association between the 3D positions of the markers and vertices in the base mesh;using the 3D positions of the markers to determine motion of the vertices of the base mesh; andconstructing a texture map from the n camera images for each of multiple frames in the video sequence.
