首先以心理动力学中的心理能量概念为基础,分析了情感能量以及表示情感状态的相关参数.然后根据情感能量守恒定律,研究了情感能量分配结构的数学表示方法和情感能量分配模型,进一步分析了情绪状态的变化过程,提出了情绪状态刺激转移过程的隐马尔可夫链及其模型算法;利用MATLAB建立相关情感状态变化的仿真研究平台,进一步研究了情感状态的变化规律.最后根据以上情感模型及其变化规律构建出表情机器头的综合研究平台,仿真结果与机器头实验数据的一致,验证了仿真模型的有效性.
Firstly, based on the concept of psychological energy in psychodynamics, this paper analyzes the emotional energy and the related parameters that represent the emotional state.And then according to the law of conservation of emotional energy, we study the mathematical expression and the emotional energy distribution model of the emotional energy distribution structure. The change process of emotional state is proposed and the Hidden Markov Chain which stimulates the transfer process of emotional state and its model algorithm are put forward.The simulation research platform of related emotional state changes is established by MATLAB to further study the changing law of emotional state.Finally, Model and its variation rule to build a comprehensive research platform for the expression machine head. The simulation results are consistent with the experimental data of the machine head, and the validity of the simulation model is verified.
