Problems solved by technology

The principle of the method based on orthogonal images is very simple, but generally requires manual interaction to determine the position of facial feature points, and requires the user to take an orthogonal image, which is cumbersome to operate in practice

Abstract

The invention discloses a fast modeling method and system of human face which based on sheet photo. First, importing a photo of facade human face and a universal model of three-dimensional human face, then in allusion to the photo of facade human face, fixing the outline position of the true human face organ, and ascertaining the outline control point; in allusion to universal model of three-dimensional human face, demarcating the model control point according to the said outline control point, establishing the connection between the said model control point and outline control point corresponding to the said, according to the connection between the said model control point and outline control point, fitting the model by making use of universal model of three-dimensional human face. Adjusting the model control point according to the location of the outline control point, to make the entire location of organ similar between three-dimensional human face and human face; the fitted model adds vein. This invention can build the human face model rapidly in front human face; the operation is easy, the achievable human face model have very strong sense of reality within certain angle range.

Description

technical field [0001] The invention relates to the field of face image processing, in particular to a method and system for modeling a face. Background technique [0002] The current face modeling methods based on still pictures can be divided into two categories: one is the traditional shape reconstruction method based on multiple photos, and the other is the model fitting method based on orthogonal pictures. [0003] Traditional shape reconstruction methods based on multiple photos generally include the following steps: camera calibration, feature point matching, 3D point reconstruction, triangulation network construction, and texture mapping. The theoretical basis of the traditional reconstruction method is relatively mature, but it is difficult to implement. [0004] The purpose of camera calibration is to calculate the camera’s internal orientation elements (focal length, principal point, distortion parameters, etc.) and external orientation elements (camera’s spatial...
