【摘要】 眼电干扰和电磁干扰是汽车驾驶脑电测量中常见的两种干扰,通过用小波分析和独立分量分析两种信号处理方法对脑电的干扰情况进行了分析和去除。结果表明两种方法都能用在驾驶时脑电的干扰去除中,小变换方法适用于通道数少,实时性要求较高的情况,而独立分量分析方法则适用于多通道的情况。更多还原

【Abstract】 EOG interference and electromagnetic interference are two kinds of main interferences in the EEG measuring during driv-ing, wavelet transform and independent component analysis methods were applied to analyze the interferences of EEG. The results in-dicate that the two methods both can be applied to wipe off the interferences of EEG in driving, and wavelet transform method was suited when the channels of EEG were one or two and the high real-time was requested, ICA method was suited when the channels of EEG were more than two.更多还原
