    • 生物医学工程 生物医学工程
    • 计算机视觉 计算机视觉
    • 医疗信息学 医疗信息学

    背景情况:

    • 无接触式,基于摄像头的睡眠监测提供了对睡眠健康和事故预防的用户友好的评估.
    • 与传统摄像机相关的隐私问题限制了基于摄像机的睡眠监控系统的广泛采用.
    • 现有的方法通常需要直接对象识别,在家庭和医院等敏感环境中构成隐私风险.

    研究的目的:

    • 开发和评估一个新的隐私保护的睡眠监测框架,使用一个失焦的摄像头.
    • 测量包括心率 (HR),呼吸率 (RR),睡眠姿势和运动在内的关键睡眠参数,而不影响用户的隐私.
    • 为了证明使用光学模糊图像用于可靠的睡眠健康评估的可行性.

    主要方法:

    • 基于ResNet-18的框架被设计成一个独立的生理学和语义分析分支.
    • 使用失焦的摄像头来防止面部识别,确保用户的隐私.
    • 测量了睡眠参数,包括心率 (HR),呼吸率 (RR),睡眠姿势和运动.

    主要成果:

    • 在HR (R=0.9076),RR (R=0.9734),和运动 (R=0.9946) 的测量值和参考值之间观察到很高的相关性.
    • HR和RR的平均绝对误差分别为每小时5.2bpm和1.5bpm.
    • 睡眠姿势检测准确度达到94.5%,可靠的估计覆盖了HR (72.1%) 和RR (93.6%).

    结论:

    • 不聚焦的基于摄像头的睡眠监控有效消除了隐私方面的担忧.
    • 拟议的框架允许可靠地测量健康信息学的基本睡眠参数.
    • 这种方法在各种环境中对不引人注目的和保护隐私的睡眠监测具有重大前景.
