| 摘 要： | 针对平静（无情感激发状态）和恐惧（有情感激发状态）这两类情感状态,采集了其心电信号数据样本,研究了有情感和没情感状态下心电信号中的情感信息。通过分析这两类情感状态下的心电信号的QT间期对RR间期的散点图、功率谱图的1/f分布以及心率变异性（HRV）信号的Poincare截面图,计算得到了这些非线性特征的关于两类情感状态的分类识别率,同时与心电信号统计特征的识别率做了对比。发现此种提取心电信号非线性特征的方法较于之前的统计特征方法,在识别有情感和没情感这两类情感状态时具有较好的识别效果。

| Abstract: | According to the emotional states of calm and fear,some emotional information of the Electrocardiogram(ECG)data samples were collected,and researched in both emotional and emotionless states.By the analysis of scatter plots of QT-RR intervals,the 1/f distribution law of ECG signals spectrum and the poincare sections of Heart Rate Variability(HRV),the recognition rate of nonlinear characteristics with these two types of emotional states was calculated,and compared with the recognition rate of statistical characteristics.The results indicate that extracting nonlinear characteristics of ECG signals has a better recognition result compared with statistical characteristics when distinguishing emotional states and emotionless states. |
