Summary: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.
