Abstract: To avoid the shortcomings that it is imprecise to use feature line to locate the intersection of the adjacent photographic images in traditional texture image generation method，a new algorithm called “geometric model segmentation” is introduced.Through cutting the geometry model of human’s head，the contours of the divided model photos are obtained to manicure the corresponding face photos as the boundary line.The manicured face photos can be used to generate texture picture without overlapping and gap between the adjacent pictures.The cylindrical projection is introduced to construct 3D specific face model through the texture mapping by using of the above texture picture.The experiments show that the new algorithm is an effective way to generate texture images in photo-realistic 3D human face modeling.
