Virtual human eye emotion expression simulation method

Abstract

The invention discloses a virtual human eye emotion expression simulation method, which comprises the following steps of: firstly, acquiring a three-dimensional human eye mesh model, namely, three-dimensional mesh data; secondly, selecting mesh points at eye areas of the model according to the motion characteristics of eyes as motion control points; and finally, driving the motion of boundary control points by adopting a crank and rocker mechanism model to simulate real eye motion. In the method, the same mathematic model is adopted to realize the repeated motion process of opening and closing the eyes under the condition of continuous time and produce richer eye closing motion reflecting different emotions by regulating parameters such as position relationships among different rods, initial mounting position of a crank and the like. In the method, the mathematic model is simple; and the method is explicit in physical significant, simple to control, easy to implement and high in reality.

Description

technical field [0001] The invention relates to the field of computer vision, in particular to the field of three-dimensional human face animation research. Background technique [0002] Face is one of the important characteristics of everyone, through which we can identify others, observe their mood, understand their health status, etc. In recent years, with the rapid improvement of computing power and the vigorous development of network applications, the research on facial animation has once again become a very active field in computer vision and human-computer interaction. As an important sensory organ of the face and a key emotional carrier, the eyes play an irreplaceable role in transmitting information and expressing emotions, but at the same time, the physiological structure of the eyes is very complicated, and the eye movements are very rich. Reproducing realistic eye movements has always been an important and challenging topic in the study of facial animation. [...

Problems solved by technology

[0012] In order to overcome the shortcomings of the prior art that the control of grid points is not strong when simulating the closed movement of human eyes, and the simulation results are not very realistic, the present invention proposes a method for simulating the emotional expression of virtual human eyes to make up for the above method Insufficient in grid point level control, improve the realism of human eye movement animation
