核心发现

这篇PRISMA系统综述对2021-2025年间发表的深度学习驾驶员嗜睡检测研究进行了系统审查，揭示了两个关键问题：

  1. 准确率-延迟权衡普遍存在但鲜少报告： 高准确率模型通常需要更大计算量，但大多数论文未报告推理延迟
  2. 嵌入式部署验证严重缺失： 绝大多数研究仅在桌面GPU上验证，未在边缘设备（NPU/DSP）上测试

关键问题深度分析

1. 准确率-延迟权衡

架构 平均准确率 参数量 推理延迟 边缘可行性
轻量CNN (MobileNet) 89.2% 3.2M 8ms ✅
标准CNN (ResNet18) 91.5% 11.7M 15ms ✅
CNN+LSTM 93.5% 18.3M 25ms ⚠️
CNN+Attention 94.8% 25.6M 35ms ⚠️
Transformer 95.1% 85.0M 120ms ❌
多模态融合 96.1% 45.0M 80ms ❌

论文结论： 准确率每提升1%，参数量平均增加2.3倍，延迟增加1.8倍。但仅有4篇论文报告了推理延迟。

Euro NCAP场景 综述覆盖度 常用方法 准确率范围 延迟范围
F-01 PERCLOS≥30% 63.6% CNN+EAR 89-95% 15-50ms
F-02 闭眼>1.5s 50.0% CNN+LSTM 91-96% 20-80ms

F-05 综合疲劳 18.2% 多模态 93-96% 30-120ms

总结

这篇PRISMA系统综述揭示了DMS深度学习研究的学术-工程鸿沟：

  1. 学术研究偏重准确率： 持续追求SOTA，忽视部署约束
  2. 工程验证严重不足： 仅4.5%在边缘设备验证，2.3%报告功耗
  3. 多模态融合是趋势： 视觉+rPPG/视觉+CAN是最具性价比的融合方向
  4. 报告标准亟待建立： 需要强制报告延迟、模型大小、功耗、量化损失

对IMS团队的直接启示：

  • 所有DMS模型评估报告必须包含：推理延迟、模型大小、量化后准确率、边缘设备验证
  • 优先验证视觉+rPPG融合方案（无额外硬件成本）
  • Euro NCAP合规性验证必须在目标硬件（QCS8255）上完成，不能只在桌面GPU上验证
