如图1所示,为本申请实施例提供的一种生命体征监测设备10的结构示意图,包括图像获取单元11、特征提取单元12、处理单元13、显示单元14和存储单元15。其中,图像获取单元11可以包括摄像头采集单元110和面部图像捕获单元111。
以图1所示的生命体征监测设备为例,如图2所示,本申请提出的生命体征监测方法可以包括但不限于如下步骤:
步骤S101、通过图像获取单元获取一帧用户进行呼气和吸气动作的第一人脸图像。
在本申请实施例中,通过摄像头采集单元110记录用户在短时间内按照呼气、吸气操作说明进行呼气和吸气动作的彩色图像。这里,呼气和吸气动作的彩色图像可以为连续的多帧图像。之后,通过面部图像捕获单元111利用机器学习模型(例如,人脸识别模型)对摄像头获取的彩色图像进行处理,以确定彩色图像中所包含的人脸的位置。之后,通过获取的人脸的位置以创建人物所对应的完整人脸图像的图像补丁。
考虑到并非图像获取单元11获取到的所有彩色图像都用于特征提取,在特征提取之前,可以对获取到的彩色图像进行筛选,得到包含PPG信号的彩色图像。以这种方式,可以最大限度地减少噪声对PPG信号的影响,大大提高了生命体征监测的准确率。
步骤S102、通过所述特征提取单元对所述第一人脸图像进行处理,得到所述用户的生命体征数据。
在一些实施例中,通过特征提取单元对第一人脸图像进行处理,得到用户的生命体征数据的实现过程可以包括:在第一人脸图像中提取感兴趣区域ROI,其中,所述感兴趣区域包括PPG信号的像素;之后,对感兴趣区域ROI进行掩蔽,以消除第一人脸图像中包含的噪声的像素或不明显PPG信号的像素,得到第二人脸图像;最后,在第二人脸图像中提取用户的生命体征数据。
在实际应用中,可以使用计算机视觉算法对感兴趣区域ROI进行识别,以估计人物的面部特征,面部特征可以是面部结构(例如,眼睛、鼻子、嘴巴等)的位置点。这些位置点被用作参考点来估计该点与摄像头之间的角度。通过计算该点的表面法线,然后,计算表面法线和摄像头方向之间的角度差。之后,执行面部表面变换,以将每个位置点的角度映射到2D地图上并填充该位置点之间的像素,并执行外推。从而,生成的2D地图可以用于估计面罩,该面罩表示人脸中包含PPG信号的区域,由于其对摄像头的可见性而具有更高的显著性。具体实现可以如图3所示,执行过程中出现的结果变化可以如图4所示。之后,使用所得到的掩码,通过布尔与运算对从第一人脸图像(也即原始人脸图像) 中提取到的感兴趣区域ROI进行掩蔽,以消除第一人脸图像中包含的噪声的像素或不明显PPG信号的像素,得到第二人脸图像。从而可以在第二人脸图像中提取用户的生命体征数据。在一些实施例中,在获取到第二人脸图像之后,可以使用信号增强算法增强第二人脸图像中所包含的PPG信号,得到第三人脸图像,从而可以在第三人脸图像中提取用户的生命体征数据。其具体实现可以如图5所示。在实际应用中,信号增强处理需要一些人脸特征或者一段时间的人脸特征变化。
在本申请实施例中,用户的生命体征数据包括心率、心率变异分析、血氧饱和度、压力、血压、呼吸频率、温度中的至少一种。
步骤S103、通过所述处理单元对所述用户的生命体征数据进行处理,得到所述用户的健康状况。
可以理解的是,用户的健康状况可以用来确定用户罹患某种疾病的风险。在实际应用中,可以通过机器学习模型对用户的生命体征数据进行处理,得到用户罹患某种疾病的风险。在一些实施例中,可以通过机器学习模型来分析给定的生命体征数据,并提高估计用户罹患某种疾病的风险的准确率,以最大限度的减少任何可能的错误。然后,生成用户的健康报告。
步骤S104、通过所述显示单元将所述用户的健康状况以图表或曲线的形式进行显示。
示例性地,通过显示单元14显示的用户的健康报告可以如图6所示。
示例性地,如图7所示,健康报告可以以人体不同的机能系统进行显示。
在一些实施例中,如图8a所示,在执行完步骤S103之后,还可以执行步骤S105,接下来进行具体阐述:
步骤S105、通过所述处理单元,根据所述用户的健康状况或历史健康状况输出健康建议。
在一些实施例中,根据所述用户的健康状况输出健康建议,包括:
在健康状况属于一级异常的情况下,输出第一预警信息,以提示用户需要第一时间求助医务人员进行治疗;或者,
在健康状况不属于一级异常的情况下,基于表征异常的健康状况输出健康建议。
对于本申请实施例,通过对生命体征数据进行分析,可以准确地判断出异 常的生命体征数据及异常级别,并可根据异常级别进行相应的自助就医,有效避免身体异常时救助不及时、延误医治等情况的发生。
之后,可以通过显示单元14输出健康建议。
在一些实施例中,生命体征监测设备可以接收用户针对健康状况输入的反馈结果,之后,将用户的健康状况和用户输入的反馈结果存储在存储单元15中。进一步地,存储单元15可以存储该用户的历史数据,处理单元13可以利用该用户的历史数据优化算法,以输出更有针对性的健康建议。
总的来说,生命体征监测设备可以通过图像获取单元来获取用户进行呼气和吸气动作的第一人脸图像,之后,通过特征提取单元对第一人脸图像进行处理,得到用户的生命体征数据,最后,通过处理单元对用户的生命体征数据进行处理,得到用户的健康状况。以这种方式,无需借助专用监测设备便可便捷地检测用户的生命体征,有利于用户实时了解自身的健康状况,在一定程度上可以避免突发疾病的发生。
