Abstract

Embodiments of the present invention disclose a three-dimensional head modeling method. The method comprises: drawing an initial 3D head model by OpenGL ES; according to a preset facial feature point and non-feature points, establishing a facial model in the initial 3D head model by means of a well-configured Candide3 model; establishing an afterbrain model by means of a quadratic Bezier surface according to contour information provided by the established facial model; combining the facial model with the afterbrain model to form a first 3D head model; adjusting the first 3D head model according to a human face feature point extracted from an acquired image, so as to obtain a second 3D head model; and performing texture mapping on the second 3D head model, so as to obtain a target 3D head model. The present invention further discloses a 3D head modeling apparatus. By adoption of the method and apparatus provided by the present invention, the problems of a large processing data volume and high costs of 3D modeling in the prior art are solved, and time and cost for modeling are saved.

Description

technical field [0001] The invention relates to the field of computers, in particular to a three-dimensional head modeling method and device. Background technique [0002] With the development of electronic technology and mobile Internet technology, the functions of mobile electronic devices (especially smart phones) are becoming more and more powerful, which can help people complete various affairs or provide people with various services conveniently and quickly. The more inseparable from mobile electronic devices. [0003] Currently, people are studying how to better create a realistic three-dimensional head model of a person on a mobile electronic device that is suitable for the person being photographed. In the prior art, on a mobile electronic device, such as a mobile electronic device with an Android operating system, the three-dimensional environment realized is mainly an application related to games and buildings, such as a three-dimensional game scene, a three-dime...
