实施例一
参见图1至图6所示，一种测肤仪器1，包括：
导电的两接触端子10；
发光组件11，用于发出光源；
图像采集组件12，用于采集皮肤图像；
控制电路，所述控制电路与所述两接触端子10分别相连接，以控制一个接触端子发出信号及接收另一个接触端子输出的信号，并根据接收的信号获取两接触端子10与皮肤的接触状态；所述控制电路与所述发光组件11相连接以在两接触端子10均接触皮肤时开启光源，以及在两接触端子10不全接触皮肤时关闭光源；所述控制电路与所述图像采集组件12相连接以在光源开启后，根据画面的清晰度控制进行图像采集，和/或，控制进行图像采集并检测采集图像的清晰度。
具体的，所述控制电路的控制芯片(如单片机或MCU)与两接触端子10分别相连接，测肤仪器1开机后，控制芯片通过一输出端口向一个接触端子(第一接触端子101)发送持续的脉冲信号(如PWM信号)，第一接触端子接收到 脉冲信号后，对外发出信号，未与皮肤接触时，另一个接触端子(第二接触端子102)通过空气接收到第一接触端子发出的信号(即与空气形成回路)并经电子元器件(如电阻等)后输出信号给控制芯片，控制芯片通过一接收端子接收第二接触端子输出的信号，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，另一个接触端子(第二接触端子102)通过人体皮肤接收到第一接触端子101发出的信号(即与人体皮肤形成回路，参见图5所示)并经电子元器件(如电阻等)输出信号给控制芯片，控制芯片通过一接收端子接收第二接触端子102输出的信号，由于皮肤具有导电性，因此在与皮肤接触后，控制芯片可接收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，判断出两接触端子10已与皮肤接触，从而控制开启光源；同样，当控制芯片检测到该电压信号小于预设电压值时，判断出两接触端子10中至少一个未与皮肤接触，从而控制开启关闭。
本发明在测肤仪器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；本发明在图像采集前和/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。

S102，检测接收到的电信号，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；
S104，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；
S106，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104～106。
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，所述控制芯片与两接触端子分别相连接，控制芯片通过一输出端口向一个接触端子(第一接触端子)发送持续的脉冲信号(如PWM信号)，第一接触端子接收到脉冲信号后，对外发出信号，未与皮肤接触时，另一个接触端子(第二接触端子)通过空气接收到第一接触端子发出的信号(即与空气形成回路)并 经电子元器件(如电阻等)后输出信号给控制芯片，控制芯片通过一接收端子接收第二接触端子输出的信号，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，另一个接触端子(第二接触端子)通过人体皮肤接收到第一接触端子发出的信号(即与人体皮肤形成回路，参见图5所示)并经电子元器件(如电阻等)输出信号给控制芯片，控制芯片通过一接收端子接收第二接触端子输出的信号，由于皮肤具有导电性，因此在与皮肤接触后，控制芯片可接收到一个骤变的较大的电信号值。
所述电信号可以为电流信号或电压信号，本实施例中优选为电压信号，当控制芯片检测到该电压信号大于预设电压值时，判断出两接触端子已与皮肤接触，从而控制开启光源；同样，当控制芯片检测到该电压信号小于预设电压值时，判断出两接触端子中至少一个未与皮肤接触，从而控制开启关闭。
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11和图12所示，所述S102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，需要对两接触端子的接触时间进行判断。
本实施例中，所述S104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S104之后，还包括：
S105，对采集的图像进行清晰度判断，如果为清晰，执行S106，否则，语音提示重新采集，重新开启对应的光源后重复步骤104～106。
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。
一具体实施例中，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。
另一具体实施例中，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。
所述S104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S106之后，还包括：
S108，提示下一皮肤检测点，并重复步骤102～106。
本发明能够自动切换光源、自动开启光源/关闭光源、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。
实施例四一种测肤方法可用于实施例一所述的一种测肤仪器；
实施例四一种测肤方法可用于实施例二所述的一种测肤系统；
实施例四一种测肤方法可用于实施例三所述的一种测肤系统。
以上所述，仅为本发明较佳的具体实施方式；但本发明的保护范围并不局限于此。任何熟悉本技术领域的技术人员在本发明揭露的技术范围内，根据本发明的技术方案及其改进构思加以等同替换或改变，都应涵盖在本发明的保护范围内。
工业实用性
本发明一种测肤仪器及测肤方法，其测肤仪器在贴紧皮肤后才开启光源，同时在画面清晰后才启动拍照，避免光源晃眼及提高检测结果准确度，提升了用户的体验感，适用范围广，具有良好的工业实用性。
