本公开要求于2022年08月19日提交的申请号为202210998046.1、名称为“一种带水分检测功能的测肤仪器、测肤系统及测肤方法”的中国专利申请的优先权，该中国专利申请的全部内容通过引用全部并入本文。
技术领域
本公开涉及皮肤检测技术领域，特别是一种带水分检测功能的测肤仪器、系统、方法及相关设备。
背景技术
利用皮肤检测仪来测量皮肤水分的皮肤检测仪已经得到广泛应用，在皮肤美容护理以及医疗应用中受到极大的重视。
现有技术中普遍是利用传感器、电极等技术手段获得皮肤的电容或容抗等参数，再利用电容或容抗与皮肤水分之间的对应关系，得到皮肤的水分状况。对比文件1“一种皮肤水分测量方法，200510011875.2”公开了使用两个无表面绝缘层覆盖的金属电极做为测量探头，将探头接触待测皮肤表面以测量角质外层的等效电阻抗值；向探头提供的频率50KHz以下的方波信号；仅使用一个电路放大元件组成放大电路对所述测量探头接收到的响应信号进行放大处理；通过AD转换方法采集上述放大后的电压值，存储在单片机中，再根据存储在单片机中的电压值与水分含量值的关系表，查找出相应的水分含量值。对比文件1保证了每次测量的对象为角质外层，但无法保证用户每次使用的力度一样，影响检测结果。对比文件2“一种便携式恒压皮肤水分含量检测装置及检测方法，202010181881.7”公开了电容检测探头为可伸缩式探头，在探头接触皮肤后压缩弹性组件，使探头收回到壳体内，因每次弹性组件被压缩的程度相同，从而排除用户用力不同对检测的干扰，保证每次检测时电容电极所受压力相同，从而保证水分检测的准确。对比文件2通过弹性组件来保证每次检测的压力相同，随着使用次数的增多，这种硬件检测的可靠性会逐渐降低。

实施例一
参见图1至图8所示，一种带水分检测功能的测肤仪器1，包括：
导电的发射端子10和接收端子11；
图像采集组件14，用于采集皮肤画面和/或皮肤图像；
水油采集电路12，与所述接收端子11相连接，包括采样电阻R5；
控制电路13，与所述图像采集组件14和水油采集电路12分别相连接，在所述发 射端子10和接收端子11均接触皮肤后，根据图像采集组件14采集到的皮肤画面的清晰度和/或根据图像采集组件14采集到的皮肤图像的清晰度控制从水油采集电路12采集水油电压。
发射端子10和接收端子11具体的，所述控制电路的控制芯片(如单片机或MCU)与发射端子10和接收端子11分别相连接，带水分检测功能的测肤仪器1开机后，控制芯片通过一输出端口发送持续的低于50KHz的方波信号(如2.6KHz的PWM信号)，发送至导电的发射端子10，发射端子10接收到方波信号后，对外发出信号，未与皮肤接触时，接收端子11通过空气接收到发射端子10发出的信号(即与空气形成回路)并经水油采集电路12后输出信号给控制芯片，由于空气在绝大部分情况下是没有导电性(偶尔有极微弱的导电性)，因此控制芯片接收到的电信号为0或一个较小的值；与皮肤接触后，接收端子11接收到发射端子10发出的信号(即与人体皮肤形成回路，参见图7所示)并经水油采集电路12输出信号给控制芯片，由于皮肤具有导电性，因此在与皮肤接触后，控制芯片可采集到一个骤变的较大的电信号值。本实施例中，所述的电信号可以是电压信号，当控制芯片检测到该电压信号大于预设电压值时，判断出发射端子10和接收端子11已与皮肤接触，进一步根据图像采集组件14采集到的皮肤画面的清晰度(拍照前判断清晰度)和/或根据图像采集组件采集到的皮肤图像的清晰度(拍照后判断清晰度)控制从水油采集电路采集水油电压，将采集到的电压信号作为水油电压。在控制芯片内，可以通过存储的水油电压-水分值线性方程或水油电压-水分值存储表获取到与检测水油电压对应的水分值。
本公开在发射端子和接收端子均接触皮肤后，不直接采集水油电压，而是在检测到皮肤画面和/或皮肤图像清晰后才采集水油电压，即图像采集模块的焦距能够保持稳定，保证了每一次测肤所使用的力度是相同的，避免因使用不当而影响水分检测结果的准确性，提升了用户的体验感。
本实施例中，参见图3所示，所述水油采集电路12还包括：滤波电路；所述滤波电路设置在所述接收端子11和所述采样电阻R5之间。
具体的，所述滤波电路可以是RC电路，具体包括如图所示的电容C1和电阻R4，所述电容C1与所述接收端子11相连接，能够滤除由输入端引入的干扰噪声，消除因外接输入点动作时产生的抖动引起的不良影响，起到平滑电压的作用。
进一步的，所述水油采集电路12还包括：防止电流逆流的二极管Q2；所述二极管Q2设置在所述接收端子11和所述采样电阻R5之间。
本实施例中，所述的带水分检测功能的测肤仪器，还包括：稳压电路15；所述稳压电路15设置在所述控制电路13与发射端子10之间，用于将所述控制电路发送的方波激励信号转换成电平稳定的方波信号。
具体的，本实施例中，参见图2所示，所述稳压电路15包括一PNP三极管Q1； 所述PNP三极管Q1的基极与所述控制电路13相连接；所述PNP三极管Q1的发射极与一电压固定的直流电源3.3V相连接；所述PNP三极管Q1的集电极与所述发射端子10相连接。
具体的，随着测肤仪器的使用，其电池的电压会发生，因此，控制电路13输出的PWM信号的高电平的电压值会发生一定的变化，如果不做处理，会导致检测到的皮肤组织不相同，最终导致后续水油电压检测不准确。因此，本实施例的稳压电路15通过引入PNP三极管Q1，并令PNP三极管Q1的发射极与一电压固定的直流电源3.3V相连接，使得最终从所述发射端子10发出的方波激励信号的高电平信号是稳定的，保证后续水油电压检测的准确性。
本实施例中，所述的带水分检测功能的测肤仪器，还包括：发光组件16；所述控制电路13与所述发光组件16相连接以在发射端子10和接收端子11均接触皮肤时开启光源，以及在发射端子10和接收端子11不全接触皮肤时关闭光源；所述光源开启后，所述图像采集组件进行皮肤画面采集和/或进行皮肤图像采集。
在带水分检测功能的测肤仪器1接触皮肤后才开启光源以使得检测区域密闭，一方面使得带水分检测功能的测肤仪器1发出的光源不受环境光的影响，保证每次的光源强度都一致，提高检测的准确度，另一方面能够避免检测光源晃眼及对眼睛造成伤害(对脸部进行检测时仪器靠近眼睛)及省电；在图像采集前和/或采集后进行清晰度检测，能够保证采集的图像为清晰图像，从而提高检测结果准确度。

实施例四
参见图11所示，本实施例一种测肤方法，包括：
S102，检测接收到的电压信号，当所述电压信号的值达到预设值时，启动采集皮肤画面和/或皮肤图像；
S104，判断采集到的皮肤画面的清晰度，当检测到清晰度达到第一预设阈值时，控制采集所述电压信号，并将所述电压信号作为水油电压；和/或，判断拍摄到的皮肤图像的清晰度，当检测到清晰度达到第二预设阈值时，控制采集所述电压信号，并将所述电压信号作为水油电压。
所述皮肤测试方法的执行主体为控制电路的控制芯片(如单片机或MCU)。具体的，所述控制电路的控制芯片(如单片机或MCU)与发射端子10和接收端子11分别相连接，带水分检测功能的测肤仪器1开机后，控制芯片通过一输出端口发送持续的低于50KHz的方波信号(如2.6KHz的PWM信号)，发送至导电的发射端子10，发射端子10接收到方波信号后，对外发出信号，未与皮肤接触时，接收端子11通过空气接收到发射端子10发出的信号(即与空气形成回路)并经水油采集电路12后输出信号给控制芯片，由于空气在绝大部分情况下是没有导电性(偶尔有极微弱的导电性)，因此控制芯片接收到的电信号为0或一个较小的值；与皮肤接触后，接收端子11接收到发射端子10发出的信号(即与人体皮肤形成回路，参见图7所示)并经水油采集电路12输出信号给控制芯片，由于皮肤具有导电性，因此在与皮肤接触后，控制芯片可采集到一个骤变的较大的电信号值。本实施例中，所述的电信号可以是电压信号，当控制芯片检测到该电压信号大于预设电压值时，判断出发射端子10和接收端子11已与皮肤接触，进一步根据图像采集组件14采集到的皮肤画面的清晰度(拍照前判断清洗度，大于第一预设阈值时)和/或根据图像采集组件采集到的皮肤图像的清晰度(拍照后判断清晰度，大于第二预设阈值时)控制从水油采集电路采集水油电压，将采集到的电压信号作为水油电压。在控制芯片内，可以通过存储的水油电压-水分值线性方程或水油电压-水分值存储表获取到与检测水油电压对应的水分值。
本实施例中，所述S102中，当所述电压信号的值达到预设值时，启动采集皮肤画面和/或皮肤图像，具体包括：
当所述电压信号的值达到预设值并持续预设时间时，启动采集皮肤画面和/或皮肤图像。
所述S102中，所述启动采集皮肤画面和/或皮肤图像之前，还包括：控制开启光源。
所述的测肤方法，还包括：
将采集到的水油电压转换成水分值。
将采集到的水油电压转换成水分值，具体包括：
通过存储的水油电压-水分值线性方程或水油电压-水分值关系表获取到与所述水油电压对应的水分值。
本实施例中，水油电压-水分值关系表如下表1所示。
表1


对应的，水油电压-水分值线性方程可如y＝0.92x+16.54，其中y表示水分值，x表示水油电压。所述的水油电压-水分值线性方程也可如y1＝0.23x+4.135，其中y1表示含水量，x表示水油电压。如上只为拟合出的线性方程，线性方程具体的参数可根据拟合方法和拟合数据不同有一定的范围变化，本实施例不做限制。
本实施例中，使用图像清晰度算法模型获取画面或采集图像的清晰度，并使用清晰度转换函数获取画面或采集图像的清晰度概率。
具体的，所述图像清晰度算法模型可以为卷积神经网络模型。具体为前期采集大量不同清晰程度的图像样本对模型进行训练，并使用训练好的卷积神经网络模型对采集到的画面或图像进行清晰度判断输出结果，再通过清晰度转换函数将卷积神经网络模型的输出结果进行数值转换获得清晰度概率。
一实施例中，使用如下清晰度转换函数将卷积神经网络模型的二分类结果进行转换。如卷积神经网络模型输出的分类结果为-0.11和3，经下述公式转换成的模糊度概率是47％，清晰度概率是95％，清晰度概率大于模糊度概率，所以最终结果判定清晰。
另一实施例中，使用如下清晰度转换函数将卷积神经网络模型的三分类结果进行转换。如图像中0.85为清晰则卷积神经网络模型判断为清晰，0.1为清晰则判断为一般清晰，0.05为清晰则判断为模糊，然后再通过清晰度转换函数换算为清晰度概率，如下：

需要说明的是，其他实施例中，也可以直接根据卷积神经网络模型的输出结果控制是否拍照。
此外，也可使用现有的任意一种清晰度计算方法计算画面或图像的清晰度。
本实施例中，所述的测肤方法还能够采集皮肤图像，并根据采集的皮肤图像获取皮肤数据，具体的，包括：
S202，检测接收到的电压信号，当所述电压信号的值达到预设值时，控制开启预设光源集中的一种光源；
S204，启动采集皮肤图像，并在拍照前检测画面清晰度，当检测到画面清晰时，控制拍照以采集图像；
S206，判断预设光源集中所有光源的图像采集是否完成，如果完成，关闭光源； 如果未完成，控制未开启光源中的一种开启，并重复步骤204～206。
所述预设光源集至少包括自然光、UV光和偏振光中的一种。具体的，可以根据需要，控制只采集一种光源下的皮肤图像还是多种光源下的皮肤图像。
参见图12和图13所示，所述S202中，当所述电信号的值达到预设值时，控制开启预设光源集中的一种光源，具体包括：
当所述电信号的值达到预设值并持续预设时间时，控制开启预设光源集中的一种光源。
使用过程中，用户可能存在误接触的情况，为了防止这种情况导致的检测触发，需要对发射端子和接收端子的接触时间进行判断。
本实施例中，所述2104还包括：
当检测到画面不清晰时，语音提示调节位置和/或调节按压力度。
本实施例中，所述S204之后，还包括：
S205，对采集的图像进行清晰度判断，如果为清晰，执行S206，否则，语音提示重新采集，重新开启对应的光源后重复步骤204～206。
所述S204还包括：根据画面或采集图像的清晰度概率判断清晰度类型，所述清晰度类型包括清晰、一般清晰或模糊；如果为清晰，控制拍照；如果为一般清晰，判断预设按键是否按下，如果按下，强制拍照，否则进行语音提示；如果为不清晰，进行语音提示。通过清晰度概率进行判断，即可判断出画面或图像为清晰、一般清晰还是模糊。本实施例中，清晰度概率为0.9以上判断为清晰，清晰度概率为0.7-0.9判断为一般清晰，清晰度概率为0.7以下判断为模糊。具体阈值可根据需要进行设置。
本实施例中，如果在外部终端设备的APP上将检测模式设置为全脸检测，则所述S206之后，还包括：
S208，提示下一皮肤检测点，并重复步骤202～206。
本公开能够自动切换光源、自动开启光源/关闭光源、语音提示水油电压采集完成、语音提示画面或图像不清晰以及语音提示测肤仪器离开皮肤等，实现了自动控制及交互，提升了用户的体验感。
