具体实施方式
为使本公开实施例的技术方案和优点更加清楚，下面将结合本公开实施例中附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本公开一部分实施例，而不是全部的实施例。通常在此处附图中描述和示出的本公开实施例的组件可以以各种不同的配置来布置和设计。因此，以下对在附图中提供的本公开的实施例的详细描述并非旨在限制要求保护的本公开的范围，而是仅仅表示本公开的选定实施例。基于本公开的实施例，本领域技术人员在没有做出创造性劳动的前提下所获得的所有其他实施例，都属于本公开保护的范围。
另外，本公开实施例中的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便这里描述的实施例能够以除了在这里图示或描述的内容以外的顺序实施。
在本文中提及的“多个或者若干个”是指两个或两个以上。“和/或”，描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。字符“/”一般表示前后关联对象是一种“或”的关系。
人脸识别是一种基于人的相貌特征信息进行身份认证的生物特征识别技术，人脸识别技术的特征是能降低个人信息泄露的概率，并采用非接触 的方式进行识别。人脸识别与指纹识别、掌纹识别、视网膜识别、骨骼识别、心跳识别等都属于人体生物特征识别技术，都是随着光电技术、微计算机技术、图像处理技术与模式识别等技术的快速发展应运而生的。在实现人脸识别时，需要人脸识别模组内设置大量电子器件，如摄像模组、主板等器件，而现有技术中往往将上述电子器件集成为一个模组，但是当其中的一个部件损坏时，往往需要将整个模组更换掉，造成资源的浪费，同时也不方便对模组进行维修。
针对以上方案所存在的缺陷，均是发明人在经过实践并仔细研究后得出的结果，因此，上述问题的发现过程以及下文中本公开针对上述问题所提出的解决方案，都应该是发明人在本公开过程中对本公开做出的贡献。
应注意到：相似的标号和字母在下面的附图中表示类似项，因此，一旦某一项在一个附图中被定义，则在随后的附图中不需要对其进行进一步定义和解释。
参考图1，图1示出了本申请实施例提供的人脸识别模组10的结构示意图。人脸识别模组10由多个层叠的层结构组成。示例性的，人脸识别模组10包括第一支架11、主板12以及传感器模组14，三者层叠设置。其中，第一支架11位于中间，主板12以及传感器模组14分列在第一支架11的两侧，从而形成一个三明治结构。
为方便理解，首先说明三者之间的关系，第一支架11作为整个人脸识别模组10的支撑结构，用于固定传感器模组14以及主板12。传感器模组14用于采用目标物的图像，而主板12用于对传感器模组14采集的图像进行处理，得到目标物的人脸信息。应理解，上述主板12根据目标物的图像采集得到人脸信息为现有技术中常见的信息处理，具体可通过处理器或电路实现，在本申请实施例中不做具体限定。
一并参考图2，图2示出了人脸识别模组10的分解示意图。第一支架11作为整个人脸识别模组10的支撑结构，第一支架11为板状结构，其具 有相对的两个表面，且两个表面分别作为装配面。在装配时，传感器模组14固定在第一支架11的一个表面，主板12固定在第一支架11的另一个表面。
应理解本申请实施例提供的第一支架11可采用金属材料或非金属材料制备而成，只需要其具备一定的支撑强度即可。示例性的，第一支架11可采用铝、不锈钢、塑料、树脂等不同材质制备而成。
主板12作为人脸识别模组的数据处理部件，其上设置有可处理传感器模组14采集的图像的电路，对于主板12上的具体电路在本申请实施例中不做具体限定，可采用现有技术中常规的处理图像数据的电路，因此在本申请实施例中不再赘述。
主板12在与第一支架11连接时，主板12与第一支架11之间采用可拆卸固定连接。具体的，可采用螺纹连接件连接或者卡合连接等不同的连接方式。
示例性的，第一支架11与主板12可通过第一螺纹连接件17连接，第一支架11上设置有与第一螺纹连接件17对应的螺纹孔。在装配时，第一螺纹连接件17穿过主板12后旋紧在螺纹孔中，从而将主板12固定在第一支架11上。
应理解，在图2中虽然示出了通过两个呈对角设置的第一螺纹连接件17将主板12锁定在第一支架11上，但是在本申请实施例中并不具体限定第一螺纹连接件17的个数，第一螺纹连接件17可采用两个、三个、四个等不同个数，只需可将主板12固定在第一支架11即可。
作为一个可选的方案，在主板12与第一支架11固定连接时，第一支架11与主板12之间形成容纳主板12上电子器件的空间。在装配时，主板12上设置有电子器件的一面朝向第一支架11，两者在固定时，第一支架11与主板12之间的间隙可容纳电子器件。此时，第一支架11可看做是电子器件的一个保护壳，从而提高电子器件的安全性。
传感器模组14用于采集目标物的人脸信息，传感器模组14包含多个摄像头，以拍摄目标物的二维图像或者三维图像。在使用时，当目标物位于传感器模组14的采集图像的范围时，传感器模组14可采集目标物的人脸图像信息，包含二维图像和三维图像。传感器模组14可包含用于采集图像的各种传感器以及辅助器件，示例性的，传感器模组14可包含投射器、第一摄像头、第二摄像头、泛光灯等电子器件。其中，投射器可发射投射光线，以向目标物投射用于识别目标物立体信息的光线。第一摄像头可拍摄投射器投射到目标物的光线形成的光斑，以获取目标物的三维信息。第二摄像头可拍摄目标物的二维图像，以获取目标物的彩色图像信息。泛光灯可提供照明，通过泛光灯照射目标物，可提高目标物的亮度。
在传感器模组14与第一支架11装配时，传感器模组14与第一支架11之间可拆卸的固定连接。具体的，传感器模组14与第一支架11之间可采用卡合连接或通过螺纹连接件连接等不同的连接方式。
以第一支架11与传感器模组14之间通过螺纹连接件连接为例进行说明。人脸识别模组10还包括了一个第二支架13，第二支架13作为传感器模组14的支撑结构。在装配时，传感器模组14固定在第二支架13。示例性的，传感器模组14通过粘接的方式固定在第二支架13。
第二支架13与第一支架11层叠设置，且第二支架13位于第一支架11背离主板12的一侧。在装配时，第二支架13与第一支架11可拆卸的固定连接。示例性的，第二支架13与第一支架11通过第二螺纹连接件18连接，第一支架11上设置有与第二螺纹连接件18对应的螺纹孔。第二螺纹连接件18穿过第二支架13后旋紧在螺纹孔中，从而将第二支架13固定在第一支架11上。
在采用上述结构时，第二螺纹连接件18对第二支架13产生的夹紧力直接作用在第二支架13上，不会作用在传感器模组14上，保证了传感器模组14在装配时的安全性。
应理解，在图2中虽然示出了通过两个呈对角设置的第二螺纹连接件18将第二支架13锁定在第一支架11上，但是在本申请实施例中并不具体限定第二螺纹连接件18的个数，第二螺纹连接件18可采用两个、三个、四个等不同个数，只需可将第二支架13固定在第一支架11即可。
作为一个可选的方案，为进一步提高传感器模组14在使用时的安全性，在将传感器模组14固定在第二支架13上时，在传感器模组14与第二支架13之间设置了减震硅胶。减震硅胶用于给传感器模组14提供减振，在人脸识别模组10意外跌落或者出现碰撞时，通过减振硅胶可降低传感器模组14受到的力，提高传感器模组14的安全性。
在主板12与传感器模组14电连接时，通过柔性电路板15实现两者之间的电连接，以使得传感器模组14检测的数据可通过柔性电路板15传输到主板12进行处理。应理解，柔性电路板15仅为本申请实施例提供的一种具体实现方式，在本申请实施例中，不具体限定主板12与传感器模组14之间的电连接结构，如还可采用导线、插拔连接器实现两者之间的导电连接。
如图2所示，在采用柔性电路板15连接主板12与传感器模组14时，柔性电路板15为U型结构，柔性电路板15横跨第一支架11。柔性电路板15的第一端与主板12位于第一支架11的同一侧，且柔性电路板15的第一端与主板12电连接；柔性电路板15的第二端与传感器模组14位于第一支架11的同一侧，且柔性电路板15的第二端与传感器模组14电连接。
在本申请实施例提供的主板12可通过柔性电路板15与传感器模组14之间进行数据传输，投射器、第一摄像头、第二摄像头、泛光灯等器件均与主板连接，主板可处理第一摄像头、第二摄像头拍摄的图像，以获取目标物的人脸识别信息。另外，主板可控制泛光灯、投射器工作。上述主板与投射器、第一摄像头、第二摄像头、泛光灯之间的信息交互为现有常见的信息交互，且主板根据第一摄像头、第二摄像头拍摄图像获取目标物的人脸识别信息也为现有技术中常见的信息处理，因此在本实施例中不做具 体说明。
本申请实施例提供的人脸识别模组10还包括一个调试板16，该调试板16与主板12电连接，并用于对人脸识别模组10进行调试。示例性的，调试板16上设置有USB接口以及调试口。通过USB接口与外部设备连接以传输数据，通过调试口可连接外部设备对人脸识别模组10进行调试。
在装配时，调试板16与第一支架11可拆卸的固定连接。示例性的，调试板16可卡装在第一支架11上，或者通过螺纹连接件固定在第一支架11上。如图2中所示，调试板16通过两个第三螺纹连接件19(螺栓或螺钉)固定在第一支架11上，但应理解，在本申请实施例中并不具体限定第三螺纹连接件19的个数，第三螺纹连接件19的个数可为两个、三个等不同的个数。
通过上述描述可看出，本申请实施例提供的人脸识别模组10通过第一支架11作为支撑结构，将传感器模组14和主板12分别固定，在对人脸识别模组10上的部件进行维修或者更换时，将需要更换或者维修的部件取下即可，方便了对模组的维修，同时在部件损坏时，不需要将整个人脸识别模更换，降低了浪费。
参考图3，本申请实施例还提供了一种人脸识别设备，该人脸识别设备包括壳体，以及设置在壳体内的上述任一项的人脸识别模组10。其中，壳体作为整个人脸识别设备的支撑结构，用以支撑并保护人脸识别模组10。
壳体包括可拆卸的后壳20以及盖板30，在人脸识别模组10装配在后壳20内后，通过盖板30盖合在后壳20上，以将人脸识别模组10密封在盖板30与壳体围成的空间中。
由图3所示的结构可看出，本申请实施例提供的人脸识别设备采用壳体直接包裹人脸识别模组10，整个人脸识别设备比较小巧，可方便的与人脸支付的其他设备配合使用。示例性的，人脸识别设备可以方便的夹装在上位机(超市收银台)上，由于人脸识别设备尺寸比较小，因此采用较小 的安装空间即可装配。另外，人脸识别设备可直接装设三脚架支撑设置。通过上述示例可看出，本申请实施例提供的人脸识别设备由于采用比较紧凑的结构，使得尺寸较小，占用空间较小，同时也便于进行拆装。
参考图4，图4示出了本申请实施例提供的人脸识别设备的详细结构的爆炸图。在盖板30与后壳20连接时，盖板30与后壳20之间通过盖板背胶50密封连接，从而提高了人脸识别设备的密封性能，降低灰尘进入到壳体内的概率。
作为一个可选的方案，人脸识别设备还包括用于封堵传感器模组14与窗口之间间隙的防尘棉50。如图4所示，在装配时，防尘棉50设置在传感器模组14与盖板30之间，在且盖板30盖合在后壳20上时，防尘棉50被盖板30挤压变形从而密封盖板30与传感器模组14之间的间隙。
应理解，盖板30及防尘棉50上具有与传感器模组14配合的窗口。示例性的，在传感器模组14包含有两个传感器、一个投射器和一个泛光灯时，盖板30及防尘棉50设置有四个窗口与传感器模组14的四个部件一一对应，以使得传感器模组14发射的光线或者接收的光线可穿过盖板30及防尘棉50。
在人脸识别模组10固定在后壳20内时，可采用不同的方式，如粘接、卡接或者通过螺纹连接件连接。示例性的，人脸识别模组10通过粘接的方式固定在后壳20内。
作为一个可选的方案，后壳20可采用金属材质制备的壳体，如铝、不锈钢等常见的导热系数较好的金属。此时，后壳20除作为人脸识别模组10的支撑结构，还可作为人脸识别模组10的散热结构。在装配时，人脸识别模组10的主板12通过导热硅胶60粘接在后壳20内。在人脸识别模组10工作时，主板12上产生的热量可通过导热硅胶60快速的散发到后壳20上，从而可提高人脸识别模组10的散热性能。
作为一个可选的方案，人脸识别模组10还可包含一个端口盖70，该端 口盖70可盖合在调试板16上的接口上，如USB口和调试口，以降低灰尘落入的概率。
如图5所示，图5示出了本申请实施例提供的一种人脸识别系统，人脸识别系统包括上述任一项的人脸识别设备100，与人脸识别设别连接的服务器200；服务器200用于存储人脸识别设备100拍摄的目标物的人脸图像。在采用上述结构时，通过第一支架作为支撑结构，将传感器模组和主板分别固定，在对人脸识别模组上的部件进行维修或者更换时，将需要更换或者维修的部件取下即可，方便了对模组的维修，同时在部件损坏时，不需要将整个人脸识别模组更换，降低了浪费。
最后应说明的是：以上实施例，仅为本公开的具体实施方式，用以说明本公开的技术方案，而非对其限制，本公开的保护范围并不局限于此，尽管参照前述实施例对本公开进行了详细的说明，本领域的普通技术人员应当理解：任何熟悉本技术领域的技术人员在本公开揭露的技术范围内，其依然可以对前述实施例所记载的技术方案进行修改或可轻易想到变化，或者对其中部分技术特征进行等同替换；而这些修改、变化或者替换，并不使相应技术方案的本质脱离本公开实施例技术方案的精神和范围，都应涵盖在本公开的保护范围之内。因此，本公开的保护范围应所述以权利要求的保护范围为准。
