Three-dimensional human face modelling approach based on front side image

Abstract

The invention relates to the technical field of computer graphics and image processing, in particular to a 3D human face modeling method based on front silhouette, which mainly models the 3D human face in a fully automatic manner. The method comprises the following steps: a general human face grid model is built by 113 feature points and 184 tri patch information arrays which are connected with the 113 feature points based on Candide parameterization; 2D position information and depth information of a specific human face are determined by virtue of human eyes location algorithm and side nose tip location algorithm by inputting two 2D images, the general face model is modified and transformed into a specific human face model; an interpolating is calculated for the human body patches by Delaunay Triangulation Technology and texture mapping is carried out by the Bilinear Interpolation Technology, thus causing the human face image to be appeared more delicate and accurate; and the method solves the problems such as low efficiency, high calculation expense, and the like, existing in the prior art.

Description

technical field [0001] The invention relates to the technical field of computer graphics and image processing, in particular to a method for modeling a three-dimensional human face based on front profile images. Background technique [0002] With the continuous development of computer graphics, three-dimensional production technology has also been developed rapidly and is widely used in various fields of social production and life. Nowadays, the rapid development of computer network and its entry into our daily life provide unlimited living space for the development and application of 3D technology. With the increasing popularization of network applications, people tend to communicate more and more in the virtual network world, from face-to-face conversations, phone calls, network chats, and mutual e-mails. Human face is an important channel for human to communicate with each other, and it is the carrier of complex expressions and languages ​​such as happiness, anger, sadne...

Problems solved by technology

According to this, there are many kinds of 3D modeling techniques at present, but most of them are based on interactive methods, which require professionals to select key points. Therefore, the work efficiency is low. At the same time, interactive 3D modeling techniques Most of them need to select hundreds of key points to achieve visually satisfactory results. Therefore, this method still has the problem of high computational overhead.
