Description

虹膜识别装置及其制造方法和应用 技术领域
本发明涉及一种光学成像设备,特别涉及一种虹膜识别装置及其制造方法和应用。
背景技术
随着互联网及其应用的普及,识别技术及身份认证方式,对于用户的信息安全具有重要的意义。
传统的识别技术基于触摸技术的发展,其藉由传感器通过接受触摸或按压事件来识别用户的身份,然而,响应以及执行该触摸或按压事件所需要的软件和逻辑比较复杂,以至于导致系统进行用户信息比对时所消耗的时间较长,而且对比结果的正确性也无法有效地保障。也就是说,基于触摸技术的识别方法可能会进行错误的信息比对,从而,不仅给用户带了不必要的麻烦,而且还会威胁到用户的信息安全。
虹膜识别技术是生物识别技术的一种,虹膜特征是人体最为稳定的生物特征之一,并且具有唯一性的特点,这给虹膜识别技术的发展和广泛应用提供了基础条件。在采用虹膜识别技术对用户身份认证时,用户不需要接触到传感器。从利用虹膜识别技术对用户身份认证的结果来看,相对于基于触摸技术发展的传统的识别技术来说,虹膜识别技术的可靠性更高。
然而,传统的虹膜识别技术也存在着较多的问题,限制了其性能的发挥。一方面,传统的虹膜识别技术采集的用户的虹膜特征的图像品质低,并且只能够在近距离内进行采集,一旦距离较远,就无法准确地对用户的虹膜特征进行捕获,因此,传统的虹膜识别技术的实用价值不高。
另一方面,传统的虹膜识别技术多采用单眼(左眼或右眼)的虹膜特征来进行处理,并且对拍摄目标眼睛的定位和环境的要求都非常高,导致传统的虹膜识别技术对用户的虹膜特征采集时的条件限制较多,并且用户的拍摄也不够方便。更重要的是,传统的虹膜识别技术采集的单眼的虹膜特征的信息量不够充分,也 进一步限制了传统的虹膜识别技术的发展。

具体实施方式
以下描述用于揭露本发明以使本领域技术人员能够实现本发明。以下描述中的优选实施例只作为举例,本领域技术人员可以想到其他显而易见的变型。在以下描述中界定的本发明的基本原理可以应用于其他实施方案、变形方案、改进方案、等同方案以及没有背离本发明的精神和范围的其他技术方案。
结合本发明的一个目的,如图1所示是根据本发明的一个优选实施例的虹膜识别应用中的补光方法及装置,其中所述虹膜识别装置100包括一虹膜摄像模组10、至少一补光组件20、一可印刷电路板30、以及其他可能的构件。
在本发明的这个实施例中,所述虹膜摄像模组10被贴装在所述可印刷电路板30上,并且在后续能够与所述补光组件20配置在一起,以形成所述虹膜识别装置100。
如图2所示,在本发明的另外一些实施例中,所述虹膜摄像模组10与所述补光组件20分别被贴装在所述可印刷电路板30上的相应位置,以使得所述虹膜摄像模组10与所述补光组件20能够相互适配,从而,形成所述虹膜识别装置100。
值得一提的是,所述可印刷电路板30可以是Flex板或PCB板,并且在所述虹膜摄像模组10与所述补光组件20之后,确保所述虹膜识别装置100在使用过程中的稳定性和可靠性。
值得一提的是,所述虹膜识别装置100能够被应用在多种外接系统上,在本发明的一些实施例中,所述外接系统包括但不限于诸如保险柜等保险装置,诸如移动电子设备、个人数字助理、个人电脑等智能设备,以及诸如在线支付程序等应用程序。
所述虹膜识别装置100还可以一后台处理组件200可通信地联接,以使得藉由所述虹膜识别装置100采集的用户的相应特征,并传输至所述后台处理组件200进行诸如分析、计算、匹配等处理。所述虹膜识别装置100采集的用户的虹膜特征,其也可以与其他识别装置来搭配用来采集诸如面部特征、指纹特征、声音特征等生物特征,以便于在后续对用户的身份进行识别,从而,确保用户的信 息的安全性。
作为本发明的一个示例,如图1和图2所示,所述后台处理组件200可以被实施为一个微处理器,并且在制造所述虹膜识别装置100的过程中,所述后台处理组件200可以被贴装在所述可印刷电路板30上,从而,藉由所述虹膜摄像模组10采集的用户的虹膜特征,可以被快速且有效地传输至所述后台处理组件200进行处理。在这个实施例中,所述虹膜识别装置100的集成化程度高,以能够在制备所述外接系统时,节省装配的成本。
如图3A是本发明的另外一个实施例的示意图,可以在所述虹膜识别装置100声预设一数据接口101,所述后台处理组件200具有一连接端201,通过所述连接端201与所述数据接口101的耦接,可以将所述虹膜识别装置100可通信地联接于所述后台处理组件200,从而,实现所述虹膜识别装置100与所述后台处理组件200之间的数据传输。
在图3B中示出了本发明的另外一个实施例,所述虹膜识别装置100与所述后台处理组件200之间可以通过无线连接的方式可通信地联接,通过这样的方式,可以确保所述虹膜识别装置100在具体应用过程中的灵活性。
值得一提的是,所述虹膜识别装置100与所述后台处理组件200之间的无线通信方式包括但不限于Wi-Fi、Li-Fi、互联网、通信网络和蓝牙等。
也就是说,所述虹膜识别装置100与所述后台处理组件200之间可以选择性地通过有线连接或无线连接的方式可通信地联接,以使得所述虹膜识别装置100可以满足不同的使用需要。
如图4A和图4B所述,在本发明的不同的实施方式中,可以提供不同数量的所述补光组件20,并且每所述补光组件20的位置可以根据需要被调整。例如,所述补光组件20的数量可以是一个,其被配置在所述虹膜摄像模组10的相应位置,以在所述虹膜摄像模组10采集用户的虹膜特征时,提供补充光源,从而,使得所述虹膜摄像模组10采集的用户的虹膜特征的图片的品质更高;所述补光组件20的数量可以是两个,其被对称地配置在所述虹膜摄像模组10的相应位置,以在所述虹膜摄像模组10采集用户的虹膜特征时,提供补充光源。在另外的实施例中,所述补光组件20的数量还可以是更多,并且每所述补光组件20环设于所述虹膜识别模组10,本发明在这方面不受限制。
值得一提的是,在上述的阐述过程中揭露的所述补光组件20的数量和位置仅作为本发明的这个实施例的优选,而并不构成对本发明的内容和范围的限制。
也就是说,为了提高所述虹膜摄像模组10在采集用户的虹膜特征时的可靠性,可以藉由所述补光组件20从所述虹膜摄像模组10的至少一个方位提供补充光源,从而,在使用所述虹膜摄像模组采集用户的虹膜特征时,用户的虹膜的反光斑能够减少,或者生成的反光斑能够位于虹膜之外的诸如巩膜等区域。
值得一提的是,所述虹膜摄像模组10在采集用户的虹膜特征时,进行的拍摄为红外光黑白拍摄,用户所处的普通环境可能因为没有足够的红外光线支撑这一取景拍摄的过程,从而,通过所述补光组件20可以提供补充的光源,来获得高品质的承载有用户的虹膜特征的图片。
因此,所述补光组件20所提供的光源为led红外光光源,以符合所述虹膜摄像模组10的拍摄的需要,并且在藉由所述虹膜摄像模组10对用户的虹膜特征进行采集时,为用户的双眼区域补充红外光,其中所述虹膜摄像模组10优选为红外摄像模组,从而,在藉由所述虹膜摄像模组10采集用户的虹膜区域的特征时,可以尽可能地避免外界可见光产生的干扰,而且,所述补光组件20的使用,也不会使用户的双眼区域感觉不适,从而,在所述虹膜摄像模组10对双眼区域图像取景拍摄的同时,在用户的虹膜区域形成均匀的亮度。而且,通过led红外光,还能够提高采集的用户的虹膜特征的精度,进而,提高所述虹膜识别装置100进行用户身份识别的效率和可靠性。
在本发明的这个优选实施例中,所述补光组件20包括一发光元件21,其中所述发光元件21优选为红外LED发光元件,以在确保所述补光组件20能够为所述虹膜摄像模组10采集用户的虹膜特征提供足够的补充红外光的情况下,降低所述虹膜识别装置100的能量耗损,以及避免对用户的眼睛造成的损伤。
如图5所示,在藉由所述虹膜识别装置100采集用户的虹膜特征的过程中,所述虹膜摄像模组10能够覆盖在用户的面部区域为内部区域,以使得所述虹膜摄像模组10在采集用户虹膜特征时,其聚焦点大致位于用户的虹膜区域,更优地,该聚焦点大致位于用户的瞳孔区域;相应地,所述补光组件20能够覆盖在用户的面部区域为外部区域,以使得所述补光组件20覆盖在用户的面部区域始终包含所述虹膜摄像模组10覆盖在用户的面部区域,并且用户的至少一只眼睛 位于内部区域。通过这种方式,所述补光组件20在任何情况下都能够为所述虹膜摄像模组10提供补充红外光源。
可以理解的是,所述补光组件20的所述发光元件21的发光角度被设置小于90度,以使得所述补光组件20所提供的补充的红外光源能够被有效地利用。值得一提的是,所述补光组件20的所述发光元件21的发光角度被设定为小于45度,从而,能够在确保所述补光组件20为所述虹膜摄像模组10提供足够的补充红外光源的情况下,降低所述虹膜识别装置100的能量耗损。
本技术领域的技术人员能够理解,所述补光组件20的所述发光元件21的发光强度随着发光角度的变化而发生变化。如图6所示,随着所述发光元件21的发光角度的增加,所述发光元件21的发光强度逐渐变小,并且所述发光元件21的发光强度与发光角度呈函数变化。可以理解的是,根据对所述发光元件21的发光强度与发光角度的测试结果显示,当所述发光元件21的发光角度处于0度至45度之间时,所述发光元件21的发光强度变化平缓,当所述发光元件21的发光角度处理45度至90度之间时,所述发光元件21的发光强度变化剧烈。
由图6示出的信息可知,在理想情况下,当所述发光元件21的发光角度为0度时,所述发光元件21的发光强度最大,此时,所述发光元件21所耗损的能量也最少。在本发明的具体应用中,所述补光组件20与所述虹膜摄像模组10之间具有一预设距离,为了使得所述补光组件20与所述虹膜摄像模组10之间能够同时作用于一个目标(如用户的虹膜等区域),所述补光组件20与所述虹膜摄像模组10之间具有角度。根据所述虹膜识别装置100的测试结果可知,当所述发光元件21的发光角度小于45度时,能够消耗最少的能量,这时,为所述补光组件20与所述虹膜摄像模组10的最佳配置状态。
如图7所示,定义所述虹膜摄像模组10与用户的虹膜之间的距离为z,所述虹膜摄像模组10与所述补光组件20的轴间距为x,所述补光组件20的倾斜角度为θ,此时,z、x与θ之间的公式关系为tanθ=z/x,并且,通过公式tanθ=z/x,可以确定所述虹膜摄像模组10与所述补光组件20之间的偏移值。本技术领域的技术人员应当理解,当z处于确定的状态时,x与θ之间具有正切函数的变化规律,此时,通过调整θ的大小,可以确定x的值或通过调整x的数值确定θ的大小。通过这种方式,可以确定所述虹膜摄像模组10与所述补光组件 20之间的偏移值。
值得一提的是,当θ的角度合理时,可以使得所述发光元件21在用户的虹膜上形成的反光斑减少,或者使得该反光斑处于用户的诸如巩膜等区域,以避免藉由所述虹膜摄像模组10对用户的虹膜特征进行取景拍摄时,生成的反光斑对图像的品质造成干扰。如图8A、图8B、图8C和图8D示出了所述虹膜识别装置100在不同的状态下采集的用户的虹膜特征的效果,实验证明,红外光源的补充以及本发明中所配置的所述补光组件20的角度和光源强度,能够使得该反光斑不会干扰所述虹膜摄像模组10对用户的虹膜特征的采集。因此,在本发明的一些实施例中,θ的角度优选为小于45度,也就是说,所述补光组件20与所述虹膜摄像模组10之间的角度优选为小于45度。
本技术领域的技术人员应当理解,当所述补光组件20的强度无法满足所述虹膜摄像模组10进行用户的虹膜特征采集时的亮度需要时,一方面还增加所述发光元件21的亮度,另一方面,可以为所述虹膜识别装置100配置两个或以上的所述补光组件20。
如图9A和图9B所示分别是用户的虹膜区域在不同的光源条件下的亮度变化示意图。
如图9A所示,在自然光条件下,藉由所述虹膜摄像模组10对用户的虹膜特征进行采集时,用户的虹膜区域的亮度大致呈梯度变化,这种情况下,导致所述虹膜摄像模组10采集的用户的虹膜特征的图像的品质较差,无法满足用户身份识别的要求,从而,导致传统的虹膜识别技术效率低下,且精确度很难得到保证。
如图9B所示,在使用所述补光组件20为用户的虹膜区域提供补充光源之后,利用所述虹膜摄像模组10对用户的虹膜特征进行采集时,用户的虹膜区域的亮度比较平均,从而,有利于提高所述虹膜摄像模组10采集的用户的虹膜特征的品质,依此,来提高所述虹膜识别装置100在使用过程中的可靠性。
值得一提的是,所述虹膜摄像模组10采集的用户的虹膜特征的图像的品质,对于所述虹膜识别装置100的运算速度和逻辑的复杂度具有重要的影响,并且对于所述虹膜识别装置100的识别范围产生影响。本技术领域的技术人员应当理解,当所述虹膜摄像模组10采集的用户的虹膜特征的品质高时,所述虹膜识别装置100的逻辑设计的复杂度能够降低,从而,对用户的身份识别所消耗的时间 越短。
在本发明的这个优选实施例中,所述虹膜识别装置100能够实现长距的用户虹膜识别,其通过所述虹膜摄像模组10的IMAGE SENSOR的PIXELSIZE的小型化,横向PIXEL QUANTITY多量化的选择方式,再结合LEN HFOV的设计值控制来延长所述虹膜识别装置100的识别距离,合理的设计可以使得所述虹膜识别装置100实现长距离的用户虹膜识别。
具体地说,所述虹膜摄像模组10的IMAGE SENSOR通过提供直径较小的像素点,并在所述虹膜摄像模组10采集用户的虹膜特征时,在双眼区域的像素数量满足至少10pixels/mm,双眼区域总像素分辨率至少1920×800,以满足虹膜识别算法的最低要求。并且,在所述虹膜摄像模组采集用户的虹膜特征时,在双眼区域的解像力满足至少450LW/PH(0.8F)。
相应地,如图10所示,本发明提供一种虹膜识别应用中的补光方法,其中所述方法包括如下步骤:
(a)提供一虹膜摄像模组10,以用户的瞳孔为大致聚焦点,通过捕获从聚焦点向四周的均匀的亮度来采集用户的虹膜特征;以及
(b)藉由至少一补光组件20为用户的眼部区域提供补充光源,以在虹膜区域形成均匀的亮度。
如图11A至图12所示,所述虹膜识别装置100还配置有一人脸摄像模组40,其中所述人脸摄像模组40可以被贴装在所述可印刷电路板30上,以使得所述虹膜识别装置100能够同时采集用户的面部特征及虹膜特征,从而,通过增加所述虹膜识别装置100捕获的用户的特征的信息,来提高所述虹膜识别装置100进行用户身份识别的精度。
如图11A所示,所述虹膜摄像模组10、所述人脸摄像模组40与所述补光组件20被集成化一个所述虹膜识别装置100,其中所述虹膜摄像模组10可以采集用户的一个眼睛的虹膜特征,也可以采集用户的两个眼睛的虹膜信息,所述补光组件20为被采集的眼睛的虹膜区域提供补充光源,所述人脸摄像模组40可以采集用户的面部特征,并且在后续,被采集的用户的面部特征及虹膜特征得以被传输至所述后台处理组件200进行处理。
值得一提的是,所述虹膜摄像模组10具有较高的像素分辨率,可达至少 1920×800,以在用户采集用户的虹膜特征时,使其生成的图像具有较高的品质;相应地,所述人脸摄像模组40可以具有较低的像素,以在确保所述虹膜识别装置100的实际使用价值的基础上,降低其成本。
值得一提的是,在利用所述虹膜识别装置100采集用户的虹膜及面部特征时,所述虹膜摄像模组10与所述人脸摄像模组40可以同时采集用户的虹膜和面部特征,也可以分别采集用户的虹膜和面部特征,然后在后续藉由所述后台处理组件200进行处理。
如图11B和图11C所示,在利用所述虹膜识别装置100采集用户的虹膜及面部特征时,所述虹膜摄像模组10在用户的面部覆盖的范围为区域1,所述补光组件20在用户的面部覆盖的范围为区域2,相应地,所述人脸摄像模组40在用户的面部覆盖的范围为区域3,其中用户的眼睛位于区域1内,并且区域1、区域2和区域3的关系为:区域3的面积包含区域2的面积,区域2的面积包含区域1的面积。
从而,在本发明的一些实施例中,所述人脸摄像模组40还可以兼具采集用户的虹膜特征,然后在所述后台处理组件200处理用户的生物特征的过程中,可以利用藉由所述虹膜摄像模组10采集的虹膜特征修正藉由所述人脸摄像模组40采集的虹膜特征,依此,来进行用户的身份识别。
值得一提的是,通过对所述虹膜摄像模组10、所述补光组件20与所述人脸摄像模组40的位置进行调整,可以满足或改变上述揭露的各区域的位置和包含关系。
如图12所示,定义所述虹膜摄像模组10的水平视场角为用户的双眼长度方向,定义所述虹膜摄像模组10的垂直视场角为用户的双眼宽度方向;相应地,定义所述人脸摄像模组40的水平视场角为人脸长度方向,定义所述人脸摄像模组40的垂直视场角为人脸宽度方向。在设置所述补光组件20与所述虹膜摄像模组10的之间的角度时,为了确保所述补光组件20的所述发光元件21产生的光源能够覆盖所述虹膜摄像模组10所能够覆盖的区域,所以,所述补光组件20的所述发光元件21的发光角度分别大于所述虹膜摄像模组10的水平视场角和垂直视场角。通过这种方式,可以使得所述补光组件20的覆盖范围大于所述虹膜摄像模组10在同一投影范围内的覆盖范围。
另外,所述人脸摄像模组40的水平视场角大于所述虹膜摄像模组10的水平视场角,相应地,所述人脸摄像模组40的垂直视场角大于所述虹膜摄像模组10的垂直视场角。这样,可以使得所述人脸摄像模组40的作用范围能够覆盖所述虹膜摄像模组10的作用范围。
参考图13和图14,从水平方向来看,人眼区域的宽度距离大致占据人脸区域的宽度距离的3/5;相应地,从纵向方向来看,人眼区域的垂直距离大致占据人脸区域的垂直距离的1/6,并且人眼区域位于人脸区域的3/6处(参照图14所示的方向)。本技术领域的技术人员应当理解,人眼区域的宽度距离与垂直距离,以及人眼区域在人脸区域的位置,对所述虹膜摄像模组10和所述人脸摄像模组40的位置的设置具有重要的影响。具体地说,如图15所示,在本发明的一些实施例中,当所述虹膜摄像模组100的所述虹膜摄像模组10与所述人脸摄像模组40纵向设置时,设定所述虹膜摄像模组与所述用户的面部的距离为30cm-40cm(值得一提的是,在本发明的优选实施例中,相对于传统的虹膜识别技术来说,30cm-40cm是所述虹膜识别装置100的有效识别距离)。
在30cm-40cm的距离范围内,可以将所述虹膜摄像模组10的水平视场角设定在大致30度,垂直视场角设定在大致15度;相应地,所述人脸摄像模组40的水平视场角设定在大致60度,垂直视场角设定在大致38度。为了使得所述人脸摄像模组40识别的区域范围在覆盖所述用户的面部区域的同时,所述虹膜摄像模组10的识别区域可以覆盖在所述用户的双眼区域,此时,所述虹膜摄像模组10与所述人脸摄像模组40的相对距离被设定相距大致29mm。
在本发明的另外一些实施例中,当所述虹膜识别装置100的所述虹膜摄像模组10与所述人脸摄像模组40水平设置时,通过分别设定所述虹膜摄像模组10与所述人脸摄像模组40的合适的水平视场角和垂直视场角,得出所述虹膜摄像模组10与所述人脸摄像模组40的相对距离。
本技术领域的技术人员应当理解,当设定的所述虹膜识别装置100与所述用户的面部距离被改变之后,一方面,可以通过调整所述虹膜摄像模组10与所述人脸摄像模组40的水平视场角和垂直视场角来实现;另一方面,还可以通过调整所述虹膜摄像模组10与所述人脸摄像模组40之间的相对距离来实现。
如图16所示,在本发明的另外一些实施例中,所述虹膜识别装置100还可 配置一指纹采集组件50,以供采集用户的指纹特征,其中所述指纹采集组件50耦连于所述可印刷电路板30,从而形成生物识别装置。
在这个实施例中,通过所述指纹采集组件50采集的用户的指纹特征可以用来辅助通过所述虹膜摄像模组10采集的用户的虹膜特征,来对用户的身份进行验证,依此,提高所述虹膜识别装置100的可靠性。
如图17所示,在本发明的另外一些实施例中,所述虹膜识别装置100还包括一声音采集组件60,以供采集用户的声音特征,其中所述声音采集组件60耦连于所述可印刷电路板30。
在这个实施例中,通过所述声音采集组件60采集的用户的声音特征可以用来辅助通过所述虹膜摄像模组10采集的用户的虹膜特征,来对用户的身份进行验证,依此,提高所述虹膜识别装置100的可靠性。

(A)在一可印刷电路板30上贴装一虹膜摄像模组10;以及
(B)配置至少一补光组件20于所述虹膜摄像模组10,在所述虹膜摄像模组10采集用户的虹膜特征时,提供补充光源;其中每所述补光组件20包括至少一发光元件21,每所述发光元件21的发光角度分别大于所述虹膜摄像模组10的水平视场角和垂直视场角。

结合本发明的一个目的,在如图20所示的一个实施例中,所述虹膜和人脸识别系统400还可以被应用在传统的所述外接系统300上,以使得通过在传统的所述外接系统300上,接入所述虹膜和人脸识别系统400,来实现所述虹膜和人脸识别系统400与所述外接系统300的安装。
值得一提的是,所述虹膜和人脸识别系统400与所述外接系统300之间可以通过有线连接的方式耦接,也可以通过无线连接的方式可通信地连接,从而,方便使用。
在一些实施例中,所述外接系统300可以被实施为一装置302和/或一电子设备304和/或具有应用程序306等,所述虹膜和人脸识别系统400能够与所述装置302、所述电子设备304与所述应用程序306之间可通信地连接。

值得一提的是,所述虹膜识别组件102捕获的所述用户500的虹膜特征的质量,对于所述虹膜和人脸识别系统400在后续的运算速度和逻辑的复杂度具有重要的影响,并且对于所述虹膜识别组件102的识别范围和能力产生影响。本技术领域的技术人员应当理解,当所述虹膜识别组件102获取的所述用户500的虹膜特征的质量越高时,所述虹膜和人脸识别系统400的逻辑设计的复杂度越低,从而,藉由所述虹膜和人脸识别系统400对所述用户500的身份信息识别所消耗的时间越短。
在本发明的这个优选实施例中,所述虹膜识别组件102能够实现长距的用户虹膜识别,其通过IMAGE SENSOR的PIXELSIZE的小型化,横向PIXEL QUANTITY多量化的选择方式,再结合LEN HFOV的设计值控制来延长所述虹膜识别组件102的识别距离,合理的设计可以使得所述虹膜识别组件102实现成距离的用户虹膜识别。
相应地,所述人脸识别组件104还包括一人脸摄像模组40,以用于获取所述用户500的面部特征,并在后续生成所述图片数据流202。在本发明的一些实施例中,为了在使得所述虹膜和人脸识别系统400具有较低成本的基础上,保证所述虹膜和人脸识别系统400的成像品质,所述虹膜识别组件102提供的所述虹膜摄像模组10具有较高的像素,以用于获得所述用户500的虹膜特征,在一些实 施例中,所述虹膜摄像模组10只需要捕获所述用户500的一个眼睛的虹膜特征,而在另外一些实施例中,所述虹膜摄像模组10可以同时捕获所述用户500的双眼的虹膜特征,并具有较高的质量。相应地,所述人脸识别组件104提供的所述人脸摄像模组40可以具有较低的像素。
值得一提的是,在利用所述虹膜和人脸识别系统400捕获所述用户500的虹膜及面部特征时,所述虹膜识别组件102与所述人脸识别组件104可以同时获取图像,也可以分别获取图像,然后通过所述后台处理组件200对所述虹膜识别组件102与所述人脸识别组件104捕获的特征进行整合处理,以生成相关的所述用户500的身份信息。

当所述操作组件308判断所述用户500的身份信息与与存在所述信息库3082中的所述用户500的身份信息匹配时,对所述应用程序308的用户身份验证程序设定完成。
值得一提的是,对所述应用程序3042设定用户身份验证程序和所述电子设备304的解锁程序时被匹配的预存在所述信息库3082中的用户身份一致。通过这样的方式,可以避免非用户对所述电子设备304中的所述应用程序3042进行用户身份验证程序的设定。

值得一提的是,根据本发明的另一方面,本发明还提供一种双眼虹膜图像数据采集模块600,其能够与一后端处理器700可通信地联接,其中所述双眼虹膜图像数据采集模块600用于采集用户的双眼虹膜特征,其包括所述虹膜摄像模组10、所述补光组件12、以及其他可能的构件。
在本发明的这个优选实施例中,所述补光组件20被配置于所述虹膜摄像模组10,其中所述补光组件20得以在所述虹膜摄像模组10捕获用户的双眼虹膜特征时,为用户的双眼区域提供补光光源,并且所述补光组件11能够在用户的虹膜区域形成均匀的亮度,这样,可以使得藉由所述虹膜摄像模组10采集的用户的虹膜特征的图像更加的清晰。
在通过所述虹膜摄像模组10采集用户的虹膜特征的过程中,所述虹膜摄像模组10能够以用户的瞳孔为大致聚焦点,通过捕获用户的双眼图像,来精确地获得用户的双眼虹膜区域的特征图像。
作为本发明的一个优选示例,所述虹膜摄像模组10包括一图像传感器芯片111、一镜头组件112以及一可印刷电路板组件113,其中所述图像传感器芯片111得以被贴装在所述可印刷电路板组件113上,所述镜头组件112覆盖在所述图像传感器芯片111的上部,也就是说,所述镜头组件112将所拍摄的双眼区域 成像在所述图像传感器芯片111的感光区域,在后续,所述图像传感器芯片111能够将承载有用户的虹膜特征的光信号转换成电信号,并经过模数转换及图像处理后获取到清晰的双眼虹膜特征图像,然后传输至所述后端处理器700,以进行用户身份的认证。
在所述虹膜摄像模组10使用的过程中,所述图像传感器芯片111提供像素数量,并使双眼区域的像素数量满足至少10pixels/mm,双眼区域总像素分辨率至少1920×800,以满足虹膜识别算法的最低要求,从而,确保所述虹膜摄像模组10能够获取清晰的承载有用户虹膜特征的图像。
所述镜头组件112用于将被拍摄物体成像在所述图像传感器芯片111的感光区域;其中在采集用户的虹膜特征时,所述镜头组件112以用户的瞳孔区域为大致聚焦点,拍摄范围覆盖双眼区域,并且在双眼区域的解像力满足至少450LW/PH(0.8F)。
值得一提的是,所述可印刷电路板组件113包括一可印刷电路板30,其中所述可印刷电路板30可以选自Flex板或PCB板的一种,以确保所述双眼虹膜图像数据采集模块600在使用过程中的稳定性和可靠性。
值得一提的是,所述后端处理器700可以被提供在装置或电子设备上,其中装置或电子设备也包括便携式装置或便携式电子设备。所述双眼虹膜图像数据采集模块600与装置或电子设备之间通过一条或多条通讯线诸如并行接口、MIPI接口、LVDS接口等传输接口进行联接,以使得藉由所述双眼虹膜图像数据采集模块600获取的用户虹膜特征的图像能够被最终传输至装置或电子设备。
还值得一提的是,装置或电子设备包括但并不限于门禁设备、保险装置、移动通讯设备、手持电子设备、个人数字助理、平板电脑、笔记本电脑、服务器等,本技术领域的技术人员应当理解,装置或电子设备还包括两项及两项以上的组合。还应当理解,装置和或电子设备仅作为一实例来对本发明的内容进行阐述和揭露,以帮助本技术领域的技术人员更好地理解本发明,装置或电子设备可以比说明书附图和具体实施方式中所描述的内容更多或更少,或者装置电子设备还可以有其他的形式。
所述补光组件20被提供并配置于所述虹膜摄像模组10,特别地,所述补光组件20与所述虹膜摄像模组10被集成为一个所述双眼虹膜图像数据采集模块 600,以用于采集用户的虹膜特征,并在后续,对用户的身份进行识别和认证,从而,方便使用。
值得一提的是,所述补光组件20优选为红外LED发光元件,从而,所述补光组件20产生的光源为LED红外光,以在所述摄像模组11采集用户的虹膜特征的过程中,为用户的双眼区域补充红外光,从而,使得用户的虹膜区域具有均匀的亮度,这样,可以使得所述虹膜摄像模组10能够更加精确地捕获用户的虹膜特征,以提高所述双眼虹膜图像数据采集模块600获取的用户虹膜特征的精确度。而且,所述补光组件20在为所述虹膜摄像模组10提供补充光源时,不会对用户的眼睛产生刺激的感觉。即是说,所述双眼虹膜图像数据采集模块600的使用不会影响用户的生理和心理健康。
还值得一提的是,所述补光组件20优选为红外LED发光元件,可以确保所述补光组件20能够为所述双眼虹膜图像数据采集模块600提供足够的补充红外光的情况下,降低所述补光组件20的能量耗损。
在本发明的一些实施例中,所述虹膜摄像模组10优选为红外摄像模组,从而,在藉由所述虹膜摄像模组10采集用户的双眼的虹膜特征时,可以减少可见光对图像成像品质造成的不良影响,依此,获得更佳的图像效果。
具体地说,所述虹膜摄像模组10的所述镜头组件112进一步包括一镜头1121、一镜座1122、一红外载波透过滤色片1123以及其他的可能的构件,所述镜座1122得以贴装在所述可印刷电路板组件113上,所述镜头1121与所述红外载波透过滤色片1123被所述镜座1122所支撑,其中在所述虹膜摄像模组10拍摄物体时,物体上的反射光线得以依次通过所述镜头1121与所述红外载波透过滤色片1123,再成像在所述图像传感器芯片111上,从而,在所述传感器芯片111上进行光-电信号的转换。
值得一提的是,所述红外载波透过滤色片1123可以滤除通过所述镜头1121的可见光部分,仅允许红外光部分通过,也就是说,所述图像传感器芯片111所接受的经由所述镜头1121部分的光线,为承载有用户的虹膜特征的红外光,从而,可以尽可能地避免可见光对所述虹膜摄像模组10获取的用户的虹膜特征的图像造成的干扰。
如图5所示,定义所述虹膜摄像模组10的水平视场角为用户的双眼长度方 向,定义所述虹膜摄像模组10的垂直视场角为用户的双眼宽度方向。在选择并设置所述补光组件20与所述虹膜摄像模组10之间的角度时,为了确保所述补光组件20产生的光源能够覆盖在所述虹膜摄像模组10所能够覆盖的区域,所以,所述补光组件20的发光角度需要分别大于所述虹膜摄像模组10的水平视场角和垂直视场角。通过这种方式,可以使得所述补光组件20的覆盖范围大于所述虹膜摄像模组10在同一投影范围内的覆盖范围。
详细地,在所述双眼虹膜图像数据采集模块600采集用户的虹膜特征的过程中,所述虹膜摄像模组10的摄像区域能够覆盖在用户的双眼区域被定义为内部区域,以使得所述虹膜摄像模组10在获取用户的虹膜特征时聚焦点能够位于用户的虹膜区域内部或附近,更优地,该聚焦点位于用户的瞳孔区域。
值得一提的是,内部区域的面积与所述虹膜摄像模组10的水平视场角和垂直视场角的设定角度相关。
相应地,所述补光组件20的发光区域能够覆盖在用户的双眼区域被定义为外部区域,由于所述补光组件20的发光角度分别大于所述虹膜摄像模组10的水平视场角和垂直视场角,从而,所述补光组件20覆盖在用户的双眼区域始终包含所述虹膜摄像模组10覆盖在用户的双眼区域。通过这种方式,所述补光组件20在任何情况下都可以为所述虹膜摄像模组10提供补充光源。
可以理解的时,所述补光组件20的发光角度被设置小于90度时,所述补光组件20的所提供的红外光源能够被有效地利用。值得一提的是,经过多次检测,当所述补光组件20的发光角度选自0度至45度之间时,所述补光组件20与所述虹膜摄像模组10的配置效果最佳。而且,也能够在确保所述补光组件11为所述双眼虹膜图像数据采集模块600提供足够的补充红外光的情况下,降低所述补光组件20的能量耗损。
如图7所示,定位所述虹膜摄像模组10与用户虹膜之间的距离为z,所述虹膜摄像模组10与所述补光组件20的轴间距为x,所述补光组件20的所述预设角度为θ,通过调整θ的大小,可以确定x的数值,通过这种方式,可以确定所述虹膜摄像模组10与所述补光组件20之间的偏移值,从而,确保制作完成的所述双眼虹膜图像数据采集模块600,其所述补光组件20覆盖在用户的双眼的区域能够始终包含所述虹膜摄像模组10覆盖在用户的双眼的区域,以确保所述双 眼虹膜图像数据采集模块600在使用过程中的稳定性和可靠性。
值得一提的是,当θ的数值合理时,可以使得藉由所述虹膜摄像模组10采集用户的双眼的虹膜特征时,在用户的虹膜区域形成的反光斑减少,或者使得该反光斑远离用户的虹膜区域,例如,在所述补光组件20的作用下,该反光斑可以生成在用户的巩膜区域或瞳孔区域等其他的位置,从而,减少反光斑的形成干扰藉由所述虹膜摄像模组10采集的用户的双眼的虹膜特征的图像品质。
如图36所示,该反光斑的生成不会影响所述虹膜摄像模组10采集的用户的双眼的虹膜特征的图像品质,从而,可以更加精确地采集用户的虹膜特征。因此,在本发明的一些实施例中,θ的合理角度为0度~45度之间。
本技术领域的技术人员应当理解,当所述补光组件20无法满足所述虹膜摄像模组10进行采集用户的虹膜特征时的亮度需要的时候,一方面可以增加所述补光组件20的亮度,另一方面,还可以为所述虹膜摄像模组10配置两个或超过两个的所述补光组件20。
值得一提的是,在提供多个所述补光组件20的情况下,每所述补光组件20得以被均匀地设置在所述虹膜摄像模组10的周围,并且同时调整每所述补光组件20与所述虹膜摄像模组10之间的角度和偏移值,从而,使得所述双眼虹膜图像数据采集模块600在进行虹膜识别和用户认证时的精度更高。
还值得一提的是,所述虹膜摄像模组10采集的用户的双眼的虹膜特征生成的图像品质,对于所述后端处理器700的运算速度和逻辑的复杂度具有重要的影响,并且对于所述虹膜摄像模组10的识别范围产生影响。本技术领域的技术人员应当理解,当所述虹膜摄像模组10采集的用户的虹膜特征的质量高时,所述后端处理器700的逻辑设计的复杂度相应降低,从而,对用户进行认证所消耗的时间就越短。
本技术领域的技术人员应当理解,合理的结构设计可以使得所述虹膜摄像模组10能够在长距范围内对用户的虹膜特征进行采集。在本发明的这个实施例中,所述虹膜摄像模组10通过所述图像传感器芯片111的像素点尺寸的小型化,横向像素点数量多量化的选择方式,再结合对所述镜头1121的水平视场角的设计值控制来延长所述虹膜摄像模组10的采集距离,从而,提高所述双眼虹膜图像数据采集模块600的实际使用价值。
值得一提的是,相对于传统的虹膜识别技术来说,所述双眼虹膜图像数据采集模块600不仅可以用来采集用户的双眼虹膜特征,而且还能够对用户的单眼的虹膜特征进行采集,且在实际的应用过程中,表现出良好的性能。
在本发明的这个优选实施例中,如图37所示,用户的双眼虹膜区域的长度为f,所述虹膜摄像模组10的焦距为a,水平视场角为β,双眼虹膜识别最近距离为b,其正好覆盖用户的双眼虹膜区域。优先设定用户的双眼虹膜识别最远距离为c,所述虹膜摄像模组10的拍摄景深为d,在最远距离时水平最大拍摄范围为e。
在本发明的这个优选实施例中,优选所述图像传感器芯片111的像素点直径为D,水平最大输出像素数为X,竖直最大输出像素数为Y;优先设定用户的双眼虹膜识别最远距离c,根据虹膜识别算法对像素的最低要求N pixel/mm,在最远距离c时需要满足此最低要求,即在f范围内保证像素数量不小于f*N,对应的所述图像传感芯片111的像面大小为f*N*D,根据相似三角形边线等比关系有如下比例关系:(f*N*D)/f=a/(c-a);在N,D,c已知的情况下,可以通过计算得出,所述虹膜摄像模组10的焦距a:a=c*D*N/(D*N+1)。
所述图像传感器芯片111水平最大输出像素数X,根据相似三角形边线等比关系:X*D/e=a/(c-a);可以通过计算得出在最远距离时,所述虹膜摄像模组10的水平最大拍摄范围e:e=X*D*(c-a)/a。
同时,根据相似三角形边线等比关系:(b-a)/a=f/(X*D);可以通过计算得出,双眼虹膜识别最近距离b:b=[f/(X*D)+1]*a。
同时,根据直角三角形函数关系:tan(β/2)=(e/2)/(c-a),可以通过计算得出,所述虹膜摄像模组10的水平视场角β:β=2*arctan[(e/2)/(c-a)。
在本发明的这个优选实施例中,根据上述计算关系,可以得出本发明揭露的所述双眼虹膜图像数据采集模块600的相关尺寸,本技术领域的技术人员应当理解,当改变设定最远拍摄距离c,或者变更不同像素点直径D的所述图像传感器芯片111,或者变更不同的所述虹膜摄像模组10的对像素数的最低要求N时,其他参数如所述虹膜摄像模组10的焦距a,最远距离时水平最大拍摄范围e,双眼虹膜识别最近距离b,以及所述虹膜摄像模组10的水平视场角β均需根据上述计算关系重新计算。
值得一提的是,但在上述所有参数确定的情况下,可以根据上述参数优选所述镜头组件112,优选所述镜头1121,满足解像力要求,匹配所述图像传感器芯片111,构成上述揭露的所述虹膜摄像模组10。

进一步地,所述虹膜摄像模组10包括一摄像光学镜组,以用于对进入所述虹膜摄像模组10的光线进行处理。具体地说,如图39、图33、图49、图54以及图59所示分别披露了本发明提供的摄像光学镜组在不同的实施例中的结构示意图,其中所述摄像光学镜组适用于制备一虹膜摄像模组,用于采集用户的虹膜特征。相应地,所述摄像光学镜组包括一第一镜片1000、一第二镜片2000、一第三镜片3000、以及其他可能的构件。
从所述摄像光学镜组的物侧至像侧(如图39所示的从左侧到右侧)依次排列所述第一镜片1000、所述第二镜片2000、所述第三镜片3000形成一个所述摄像光学镜组,并且同时形成一光轴穿过所述第一镜片1000、所述第二镜片2000与所述第三镜片3000的中部,所述摄像光学镜组还包括一光阑,其位于一被摄物与所述第二镜片2000之间。并且在后续,所述摄像光学镜组用于配合一图像感应器芯片111,以形成所述虹膜摄像模组,其中所述图像感应器芯片111具有一成像面1111,朝向所述摄像光学镜组,以供在所述图像感应器芯片111上进行光-电信号的转换。
值得一提的是,所述光阑可以是耀光光阑、视场光阑等,其选择性地设置在所述被摄物于所述第二镜片2000之间的位置,例如,所述光阑被设置在所述被摄物与所述第一镜片1000之间,或者被设置在所述第一镜片1000与所述第二镜片2000之间,其用于提高所述被摄物在所述成像面1111上的成像品质。

值得一提的是,所述第一镜片物侧面1200的凸面的曲率能够影响所述摄像光学镜组的视场角的值,也就是说,通过调整所述第一镜片物侧面1200的凸面的曲率可以提升所述摄像光学镜组的视场角,并且,在本发明的这个实施例中,所述第一镜片物侧面1200采用非光滑的设计方案,特别地,在所述第一镜片物侧面1200的周缘形成不同于中部的曲率,以修正因为所述摄像光学镜组的视场角的增加而产生的歪曲相差,从而,可以避免藉由所述摄像光学镜组采集的用户的虹膜特征的图像在成像后失真的情况。
另外,所述第一镜片物侧面1200的凸面设计,还可以进一步加强所述第一镜片1000的正屈折力,以在保证所述摄像光学镜组具有较大的视场角的基础上,进一步缩小所述摄像光学镜组的总长度,从而,使得所述摄像光学镜组的尺寸更小,以便于在后续被集成在诸如电子设备等装置上。
所述第二镜片2000为具有负光焦度的镜片,以提供负屈折力,以用于修正所述第一镜片1000的过大的正屈折力造成的相差。所述第二镜片2000具有一第二镜片像侧面2100以及一第二镜片物侧面2200,所述第二镜片像侧面2100朝向所述成像面1111,所述第二镜片物侧面2200朝向所述第一镜片像侧面1100,并且所述第二镜片物侧面2200为凹面,以用于修正所述摄像光学镜组的佩玆伐和数,从而,在所述第二镜片2000的中部和周缘都可以获得良好的成像品质,以有利于保证所述摄像光学镜组制备的所述虹膜摄像模组,在使用过程中的可靠性和稳定性。
值得一提的是,在本发明的一些实施例中,根据镜片曲率半径,所述第二镜片像侧面2100是凸面,根据镜片矢高,所述第二镜片像侧面2100可以是凸面,也可以是凹面,根据镜片以使得所述摄像光学镜组具有不同的使用性能。
所述第三镜片3000为具有负光焦度的镜片,以提供负屈折力,其中所述第三镜片3000具有一第三镜片像侧面3100以及一第三镜片物侧面3200,所述第三镜片像侧面3100朝向所述成像面1111,所述第三镜片物侧面3200朝向所述第二镜片像侧面2100,并且所述第三镜片物侧面3200为凹面。
值得一提的是,在本发明的一些实施例中,所述第三镜片像侧面3100为凸面。
在本发明的这个实施例中,所述第一镜片像侧面1100、所述第一镜片物侧面1200、所述第二镜片像侧面2100、所述第二镜片物侧面2200、所述第三镜片像侧面3100与所述第三镜片物侧面3200中至少一个侧面为非球面,以满足藉由所述摄像光学镜组制备所述虹膜摄像模组的需要。
值得一提的是,在本发明的一些实施例中,所述第一镜片1000、所述第二镜片2000与所述第三镜片3000的每个侧面都可以是非球面,以可以通过将所述第一镜片1000、所述第二镜片2000与所述第三镜片3000设计成不同的形状,来配置所述摄像光学镜组的参数,从而,尽可能地消除像差。
更多地,所述第一镜片1000、所述第二镜片2000与所述第三镜片3000的材料可以选择性地选择塑料或玻璃的一种。例如,当所述第一镜片1000、所述第二镜片2000与所述第三镜片3000选择塑料材料制成时,可以使得所述摄像光学镜组具有较低的制造成本,并且还能够降低其制造难度,以进一步提高产品良率;当所述第一镜片1000、所述第二镜片2000与所述第三镜片3000选择玻璃材料制成时,可以增加所述摄像光学镜组的屈折力配置的自由度,以在所述摄像光学镜组被制备成所述虹膜摄像模组时,藉由提高其采集用户的虹膜特征的图像的品质。
在所述摄像光学镜组被配置之后,其空间位置稳定,也就是说,所述第一镜片1000、所述第二镜片2000与所述第三镜片3000的空间位置稳定不变,并且,所述第一镜片1000、所述第二镜片2000与所述第三镜片3000之间具有一定的间隙,以防止在组装所述摄像光学镜组的过程中,相互之间出现碰撞的情况。从而,提高藉由所述摄像光学镜组制备的所述虹膜摄像模组采集的用户的虹膜特征的图像清晰,以增加所述虹膜摄像模组采集的用户的虹膜特征的信息量,从而,在后续可以对用户的身份进行可靠地认证。
在本发明中,所述第一镜片1000的第一镜片物侧面1200至所述成像面1111于光轴上的距离为TTL;所述摄像光学镜组的焦距为f,所述第一镜片1000的焦距为f1;所述第一镜片1000的所述第一镜片物侧面1200的有效半径为SD11,所述第三镜片3000的所述第三镜片像侧面3100的有效半径为SD32;所述第一镜片1000的中心厚度为CT1(所述第一镜片像侧面1100至所述第一镜片物侧面1200于光轴上的距离),所述第二镜片2000的中心厚度为CT2(所述第二镜片像侧面2100至所述第二镜片物侧面2200于光轴上的距离);所述摄像光学镜组 的光圈值为Fno。
