本发明的上述和/或附加的方面和优点从结合下面附图对实施方式的描述中将变得明显和容易理解,其中:
图1是本发明实施方式的控制方法的流程示意图。
图2是本发明实施方式的电子装置的结构示意图。

具体实施方式
下面详细描述本发明的实施方式,所述实施方式的示例在附图中示出,其中相同或类似的标号自始至终表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施方式是示例性的,仅用于解释本发明的实施方式,而不能理解为对本发明的实施方式的限制。
请参阅图1和图2,本发明实施方式的红外光源组件的控制方法,包括以下步骤:
S10:控制至少两组红外光源轮流启动;
S20:控制红外摄像头采集与至少两组红外光源对应的至少两组虹膜图像;
S30:处理至少两组虹膜图像以获取至少两组虹膜图像的清晰度;和
S40:控制清晰度最高的对应一组红外光源启动并关闭其他组的红外光源。
本发明实施方式的电子装置1000,电子装置1000包括虹膜识别模组100和处理器200。虹膜识别模组100包括红外光源组件10和红外摄像头20。红外光源组件10至少包括两组红外光源,每组红外光源的工作波长不同。作为例子,本发明实施方式的控制方法,可以由本发明实施方式的电子装置1000实现,并应用于电子装置1000。
其中步骤S10-S40可以由处理器200实现。也即是说,处理器200用于控制至少两组红外光源轮流启动,控制红外摄像头采集与至少两组红外光源对应的至少两组虹膜图像;处理至少两组虹膜图像以获取至少两组虹膜图像的清晰度;和控制清晰度最高的对应一组红外光源启动并关闭其他组的红外光源。
红外摄像头20用于接收作为有效光源的红外光源发射的红外光在虹膜的反射光线以形成虹膜图像。红外光源组件10的照明范围、红外摄像头20的视场至少部分重叠。
可以理解,红外摄像头20用于采集人眼的相关图像,而红外光源组件10则用于在虹膜识别时提供必要的红外光。因此,红外光源组件10的照明范围和红外摄像头20的视场应至少部分重叠从而实现虹膜识别的必要步骤。
随着信息安全重要性的提升,越来越多的消费电子设备中对信息进行加密以保护用户的个人信息安全,并在通过相应的验证方式获得获取相应信息与操作的权限。验证方式通常包括有字符密码、图案密码等文字图案密码,然而这种密码通常容易破解,从而使得加密失效。此外,部分电子设备如手机、平板电脑等还提供指纹作为加密方式,用户通过指纹识别进行验证,指纹虽然具有较强的差异性,但易于被他人窃取并制作成如指模等假指纹进行验证,同样不利于信息的安全。在这种情况下,虹膜识别技术作为一种安全性更高的验证方式开始被一些电子设备所采用。
虹膜识别是通过对比虹膜图像特征之间的相似性来确定用户身份,虹膜信 息具有唯一性,并且不易复制,安全性较高。
虹膜识别一般需要经过虹膜图像获取、虹膜图像处理以及虹膜图像识别的过程。
在虹膜图像获取的过程中,需要由专门的虹膜识别模组进行采集,一般地,虹膜识别模组包括摄像头以及光源,其中为保护人眼安全以及获取纹理丰富的虹膜图像,光源选择红外光,相应地,摄像头选择红外摄像头。
不同人种的虹膜颜色通常不同,例如欧美白种人的虹膜颜色通常是蓝绿色,而亚洲的黄种人的虹膜颜色通常是黑色。不同颜色的虹膜对同一工作波长的响应效率及效果均是不同的,例如对于蓝绿色的虹膜采用700nm波长的可见光也可获取虹膜图像,然而对于黑色的虹膜来说,则无法成像。
可以理解,当虹膜识别模组中仅设置单一工作波长的红外光源时,通常需折中选择,对于某一特定颜色的虹膜来说,都不是最佳选择。
本发明实施方式的红外光源组件10,包括至少两组红外光源,并且至少两组红外光源的工作波长不同,如此,可根据用户虹膜的实际情况,选择与虹膜颜色相匹配的最佳工作波长的红外光源发射红外光,从而获取效果更佳的虹膜图像。
在开始进行虹膜识别时,由于并没有相关的虹膜参数,因此控制多组红外光源轮流启动,并通过红外摄像头20分别采集与每组红外光源对应的虹膜图像,判断每组虹膜图像的清晰度,并采用清晰度最高的虹膜图像所对应一组的红外光源启动用于进行虹膜识别。
一般地,电子装置的用户较为固定,因此,在初次使用或重置电子装置时,多组红外光源轮流启动以确定虹膜识别效果较佳的一组红外光源,在后续的使用过程中,则可以直接启动所确定的效果较佳的一组红外光源进行虹膜识别。
虹膜图像的清晰度可通过比较图像的特征点的数量或图像清晰度算子如边缘强度等方式进行判断。
可以理解地,红外光源功耗较高,因此当确定最清晰的一组红外光源后关 闭其他组的红外光源。
例如,红外光源组件10包括两组工作波长不同的红外光源,一组工作波长为780nm,另一组工作波长为850nm,当前用户在初次使用虹膜识别时,两组红外光源轮流启动并通过红外光源采集对应的虹膜图像,对两组虹膜图像处理后获取对应当前用户而言,工作波长为850nm的一组红外光源效果更佳,关闭工作波长为780nm的红外光源。在后续使用过程中,可直接开启850nm一组的红外光源,直至录入新的虹膜信息或重置电子装置1000。
综上所述,本发明实施方式的红外光源组件的控制方法和电子装置1000,通过设置至少两组工作波长不同的红外光源并轮流启动以选择虹膜识别效果最佳的一组红外光源进行虹膜识别,如此,一方面使得虹膜识别模组100可工作于更多用户群体,增加了虹膜识别模组100的适用性,另一方面选择效果最佳的红外光源,提高了虹膜识别的效率。
在某些实施方式中,电子装置1000包括手机、平板电脑、智能穿戴设备以及智能家居设备等。
在某些实施方式中,红外光源还包括驱动元件,驱动元件用于选择性驱动至少一个红外光源发光。每组红外光源包括一个红外LED等,驱动元件包括开关和控制电路,其中开关用于连接每个红外LED灯与对应驱动源,控制电路用于控制开关连通和关闭。
请参阅图3,步骤S10包括步骤:
控制开关轮流连通和关闭以控制至少两组红外光源轮流启动。
在某些实施方式中,控制开关轮流连通和关闭以控制至少两组红外光源轮流启动的步骤可以由处理器200实现。或者说,处理器200用于控制开关轮流连通和关闭以控制至少两组红外光源轮流启动。
如此,通过控制开关的通断来控制相应的红外LED灯与驱动源通断,可实现对红外LED灯的控制。开关的控制可通过处理器300实现。
在某些实施方式中,控制方法包括步骤:
控制每组红外光源在采集对应的一组虹膜图像后关闭。
在这样的实施方式中,控制每组红外光源在采集对应的一组虹膜图像后关闭的步骤可以由处理器200实现。或者说,处理器200用于控制每组红外光源在采集对应的一组虹膜图像后关闭。
也即是说,每组红外光源在发光并通过红外摄像头200完成虹膜图像采集后关闭,一来可以减少不同工作波长的红外光源的同时工作的干扰,二来可节省功耗。
请参阅图4,在这样的实施方式中,步骤S40包括步骤:
控制清晰度最高的对应一组红外光源启动并控制其他组的红外光源保持关闭。
在某些实施方式中,控制清晰度最高的对应一组红外光源启动并控制其他组的红外光源保持关闭的步骤可以由处理器200实现,或者说,处理器200用于控制清晰度最高的对应一组红外光源启动并控制其他组的红外光源保持关闭。
在红外光源轮流启动时,进行虹膜识别图像采集的红外光源已关闭,当通过比较对应的虹膜图像的清晰度确定效果较佳的一组红外光源后,控制该组红外光源再次启动,并保持其他组红外光源关闭。如此,可保证虹膜识别的效率并能够节省功耗。
在某些实施方式中,控制方法包括步骤:
控制每组红外光源在采集对应的一组虹膜图像后保持开启。
在某些实施方式中,控制每组红外光源在采集对应的一组虹膜图像后保持开启的步骤可以由处理器200实现。或者说,处理器200用于控制每组红外光源在采集对应的一组虹膜图像后保持开启。
如此,可节省关闭红外光源的时间,加快选择较佳一组红外光源的速度。同时,为了防止不同组的红外光源发生干扰,需要对红外光源的位置重新设置,例如分居电子装置前面板的顶端与底端。
在这样的实施方式中,步骤S40包括:
控制清晰度最高的对应一组红外光源保持开启并关闭其他组的红外光源。
在某些实施方式中,控制清晰度最高的对应一组红外光源保持开启并关闭其他组的红外光源的步骤可以由处理200实现。或者说,处理器200用于控制清晰度最高的对应一组红外光源启动并关闭其他组的红外光源。
也即是说,多组红外光源轮流开启后,保持开启状态,当确定较佳的一组后一次性关闭其他组红外光源。
在某些实施方式中,虹膜识别模组100通常用于对当前使用电子装置1000的用户的身份进行识别,因此虹膜识别模组100通常前置,也即是设置在电子装置1000的前面板,例如设置于前面板顶端。可以理解地,虹膜识别模组100设置在电子装置1000的壳体内并自前面板露出。
在某些实施方式中,红外光源包括红外LED芯片、基板和封装体,基板用于为红外光源提供支撑。红外LED芯片以预定方式设置在基板上。红外光源组件100包括至少两组工作波长的红外光源,也即是说,两组红外光源中设置在基板上的红外LED芯片的工作波长。如此,可满足采集不同用户虹膜特征的需求。例如,在某些示例中,两组红外光源的红外LED芯片的工作波长可分别包括780nm和850nm。其中,工作波长为780nm的红外光对于蓝绿色虹膜在虹膜识别过程中效果更佳。而850nm的红外光对于黑色虹膜在虹膜识别过程中效果更佳。
封装体可以是胶体、树脂等材料,其上表面与红外LED芯片上表面平齐,封装体还包括覆盖红外LED芯片上表面的透明盖板,以作为红外光的发射窗口,盖板可以采用一般的塑料、玻璃等具有良好透射性能的材料,也可采用能够对红外光进行散射的透镜,从而加大红外光的工作范围。
红外LED芯片经封装体封装后,形成红外光源,红外光源可通过板对板连接器与电子设备的主板进行连接,并由电子设备的主电源为其进行供电。
在一些示例中,每组红外光源可包括一个红外LED芯片,也即是每个封装 体封装一个红外LED芯片。在另外一些示例中,多个红外LED芯片可共同封装于同一封装体内,也即是说,每组红外光源包括多个红外LED芯片。多个红外LED芯片的光轴可与红外摄像头20的光轴平行,也可与红外摄像头20的光轴呈一定的夹角。
在某些实施方式中,基板呈环状、多个红外LED芯片沿基板的圆周方向分布。
在这样的实施方式中,红外摄像头20设置在红外光源内侧。
具体地,基板可以是圆环状也可以是矩形环形等结构。一般地,为了用户的安全,红外光源的功率会在一定程度上进行限制,因此红外LED芯片的有效工作距离通常为10-30厘米,在有效工作范围内红外摄像头20能较为清晰的获取虹膜图像。当红外摄像头20位于红外光源内侧时,呈圆环状分布的多个红外光源中的每个到红外摄像头20的传感器的距离基本相同,各个红外光源的工作距离也基本相同。
矩形环状易于制造但仅能允许有限数量的红外LED芯片到红外摄像头20的传感器的距离基本相同,不同红外LED芯片的工作距离可能不同,因此操作中,在启动不同工作波长的红外光源时,用户可能会适当调节工作距离。
具体地,多组红外光源组件10可分别呈弧形,并共同组成环状。
红外LED芯片拥有较佳的热学性能、电性能、光学性能和机械性能,并且易于制造,价格低廉。
在某些实施方式中,每一工作波长的红外光源的数目相同或不同。
具体地,当工作波长较短时,例如780nm时,对蓝绿色的虹膜效果更佳,而对于蓝绿色的虹膜使用可见光的补光灯也能够成为有效光源,甚至使用波长更长的红外光也能够成为有效光源,而波长较长例如850nm的红外光对应的黑色虹膜仅能在当前波长或更长波长的照射下对虹膜成像,并且易受环境的影响。因此,波长越长的红外光源设置的数目越多,既能满足不同工作状况开启不同组红外光源也可满足多级功耗的需求。
其中,相同工作波长的多个红外LED芯片可共同封装为一组红外光源。
本发明实施方式的电子装置包括壳体、处理器、存储器、电路板、电源电路和虹膜识别模组。其中,虹膜识别模组包括红外光源组件和红外摄像头,红外光源组件包括至少两组红外光源,每组红外光源的工作波长不同。电路板安置在壳体围成的空间内部,处理器和存储器设置在电路板上。电源电路用于为电子装置的各个电路或器件供电。存储器用于存储可执行程序代码。处理器通过读取存储器中存储的可执行程序代码来运行与可执行程序代码对应的程序以实现上述的本发明任一实施方式的控制方法。在此过程中,处理器用于执行以下步骤:
轮流启动至少两组红外光源;
通过红外摄像头采集与至少两组红外光源分别对应的至少两组虹膜图像;
处理至少两组虹膜图像以获取至少两组虹膜图像的清晰度;和

在某些实施方式中,处理器用于执行以下步骤:
