Abstract

The invention discloses a single photo based three-dimensional face modeling method and system. The modeling method is characterized in that a deformation model is acquired through dense point correspondence and principal component analysis, and then a face model is built through feature point alignment. The beneficial effects are that 1) compared with a three-dimensional scanner, the modeling method is good in universality and flexibility, simple to operate, low in cost and applicable to the general public; 2) compared with multi-face-photo modeling, the modeling method simplifies manual operation steps and reduces the computation time; and 3) compared with traditional single-face-photo modeling, the modeling method only needs simple manual initialization, the computation amount is small, the face modeling speed is high, and an acquired face model is high in sense of reality. The modeling system comprises an image acquisition module, a conversion module, an analysis module, a molding module and a Face++API interface. The modeling system further has the beneficial effects that 1) a generated face model has a strong sense of reality, the modeling time is short, and the automation degree is high.

Description

technical field [0001] The invention relates to the fields of computer graphics and computer vision, in particular to a single photo-based three-dimensional face modeling method and system. Background technique [0002] 3D face modeling is one of the most difficult and challenging problems in the fields of computer graphics and computer vision, and it is also an interdisciplinary problem involving different fields such as physics, physiology, and psychology. [0003] With the rapid development of hardware computing power and computer graphics, people can already use computers and mobile devices to generate a variety of high-quality images and 3D models. Virtual characters constructed by computers are no strangers to everyone. It also has strong three-dimensional image processing capabilities, and people's requirements for the reality, real-time and convenience of three-dimensional modeling are getting higher and higher. Since the 1970s, 3D face modeling has become a researc...
