摘要
驾驶员疲劳检测在减少交通事故中发挥着重要作用。脑电信号作为能够直接反映驾驶员精神状态的指标,被公认为驾驶疲劳检测的有效工具。然而,脑电信号本身的高噪声特性以及在不同个体间的明显差异性,给基于脑电信号的跨被试驾驶疲劳检测带来了诸多挑战。对此,提出了一种基于局部特征处理和全局特征处理的集成网络来提取脑电信号中的特征,用于解决跨被试驾驶疲劳检测中面临的问题。在SEED-VIG数据集上进行跨被试三分类检测任务时,该模型取得了61.34%的准确率,显著优于基线方法。为了增强模型的性能,使用并改良了迁移学习方法,在跨被试三分类检测任务中,模型准确率提高了13.35%。综上,所提模型在基于脑电信号的跨被试驾驶疲劳检测上取得了良好效果,有望为该方向的研究提供新的策略。
Driver fatigue detection plays a crucial role in reducing traffic accidents.Electroencephalogram(EEG)signals,recognized as effective indicators that directly reflect a driver’s mental state,are widely acknowledged as valuable tools for fatigue detection.However,the inherent high noise characteristics of EEG signals and their significant variability across individuals pose considerable challenges for cross-subject driver fatigue detection.To address these challenges,this paper proposes an integrated network based on local feature processing and global feature processing to extract features from EEG signals,aiming at overcoming the issues in cross-subject fatigue detection.When applied to the SEED-VIG dataset for a cross-subject three-class detection task,this model achieves an accuracy of 61.34%,significantly surpassing baseline methods.To enhance the performance of the model further,it employs and refines transfer learning methods,resulting in a 13.35%increase in model accuracy for the cross-subject three-class detection task.Overall,this study has demonstrated promising results in EEG-based cross-subject driver fatigue detection,offering new strategies for future studies in this direction.
