在虹膜距离合适时启动红外光源22;和
在虹膜距离不合适时关闭或保持关闭红外光源22。
也即是说,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100实现,其中,步骤S31、S32、S33、S34和S35可以由处理器30实现。
本发明实施方式的电子装置100包括虹膜识别模组20和处理器30。虹膜识别模组20包括红外光源22。处理器30用于处理采集的人脸图像以识别虹膜区域,并在基于虹膜区域确定虹膜与虹膜识别模组20之间的虹膜距离符合启动条件时,启动红外光源22。可以理解,虹膜与虹膜识别模组20之间的虹膜距离符合启动条件时可以是指虹膜距离合适时。
本发明实施方式的控制方法和电子装置100在虹膜距离合适时启动红外光源22,从而避免在虹膜距离不合适时启动红外光源22带来的电量消耗和发热问题。
在某些实施方式中,红外光源22是指能够产生红外辐射(红外光)的光源,红外辐射是波长大于红色光波长的一定范围的电磁辐射。
在某些实施方式中,虹膜距离可以是指用户虹膜区域对应的虹膜(或眼睛)距离电子装置100(如虹膜识别模组20)的距离。可以理解,在只有一个虹膜区域时,即图像中只包含一只眼睛对应的一个虹膜区域时,虹膜距离可以是指这个虹膜区域或者这只眼睛距离电子装置100的距离;在有多个虹膜区域时,即存在多只眼睛对应的多个虹膜区域时,虹膜距离可以是指多个虹膜区域与电子装置100的距离的平均值,也可以是指多个虹膜区域与电子装置100的距离的最小值,还可以是指多个虹膜区域与电子装置100的距离的最大值,在此不做具体限定。
可以理解,在电子装置100对虹膜识别过程中,在虹膜距离过大时,电子装置100采集到的图像的虹膜区域过小,可能导致无法提取虹膜的纹理信息从而无法进行虹膜识别;在虹膜距离过小时,图像中包含的虹膜的纹理信息可能不完整,导致无法进行虹膜识别。因此可以在虹膜距离合适时才启动红外光源22。在虹膜距离不合适时关闭或保持关闭红外光源22以避免对电子装置100造成不必要的电量消耗和发热问题。需要说明的是,由于在虹膜距离不合适时红外光源22可能处于启动状态或者关闭状态,因此,关闭或保持关闭红外光源22可以是指在红外光源22处于启动状态时关闭红外光源22,在红外光源22处于关闭状态时保持关闭红外光源22。
在某些实施方式中,虹膜距离的取值范围可以是10-30厘米,也即是说,在虹膜距离处于10-30厘米之间时,说明虹膜距离合适;在虹膜距离小于等于10厘米或者大于等于30厘米时,说明虹膜距离不合适。
在某些实施方式中,电子装置100包括手机、笔记本电脑、平板电脑、智能手表或智能眼镜。在本发明实施方式中,电子装置100是手机。
请参阅图3,在某些实施方式中,控制方法包括以下步骤:
S36:判断是否收到虹膜识别请求;
S37:在收到虹膜识别请求时进入步骤S31;和
S38:在没收到虹膜识别请求时返回步骤S36。
请再次参阅图2,在某些实施方式中,处理器30用于:
判断是否收到虹膜识别请求;
在收到虹膜识别请求时进入采集图像的步骤;和
在没收到虹膜识别请求时返回判断是否收到虹膜识别请求的步骤。
也即是说,步骤S36、S37和S38可以由处理器30实现。
如此,可以在收到虹膜识别请求时才进行采集图像,从而减少电子装置100的电量消耗。
具体地,处理器30先判断电子装置100是否收到虹膜识别请求,在收到虹膜识别请求时才进行采集图像;在没收到虹膜识别请求时电子装置100不进行采集图像,而是继续判断是否收到虹膜识别请求,从而避免电子装置100一直采集图像,进而减少 电子装置100的电量消耗,提升电子装置100的续航能力。
请一并参阅图4和图5,在某些实施方式中,电子装置100包括加速度传感器40。步骤S36包括以下步骤:
S362:处理加速度传感器40的输出信号以判断电子装置100是否以预定方式操作;和
S364:在电子装置100以预定方式操作时确定收到虹膜识别请求。
请再次参阅图5,在某些实施方式中,电子装置100包括加速度传感器40。处理器30用于:
处理加速度传感器40的输出信号以判断电子装置100是否以预定方式操作;和
在电子装置100以预定方式操作时确定收到虹膜识别请求。
也即是说,步骤S362和S364可以由处理器30实现。
如此,可以通过加速度传感器40判断电子装置100是否收到虹膜识别请求,从而简化用户的操作程序,方便用户对电子装置100的使用。
具体地,加速度传感器40可以用于检测电子装置100的加速度,处理器30获取加速度传感器40的输出信号(如加速度传感器40检测到的加速度),从而获得电子装置100的操作方式,再判断电子装置100是不是以预定方式操作,在电子装置100以预定方式操作时确定收到虹膜识别请求。在一个实施例中,预定方式是2秒内左右平移两个来回,加速度传感器40检测电子装置100的加速度,当检测到电子装置100的加速度的方向在2秒内为向左、从向左变成向右、从向右变成向左、从向左变成向右时,判断电子装置100以预定方式操作,从而确定电子装置100收到虹膜识别请求。需要说明的是,处理器30通过处理加速度传感器40获取的电子装置100的加速度可以判断出电子装置100的运动轨迹,预定方式也可以是指预定的运动轨迹,如弧形、圆形、V形等。例如,在用户拿起电子装置100时,电子装置100从远离用户脸部的位置移动至靠近用户脸部的位置,期间电子装置100的运动轨迹一般为弧形,因此可以将预定方式设置为弧形,再通过加速度传感器40获取的电子装置100的加速度判断电子装置100的运动轨迹是否为弧形来确定是否收到虹膜识别请求。
请一并参阅图6和图7,在某些实施方式中,电子装置100包括可见光摄像头50。步骤S31包括以下步骤:
S312:控制可见光摄像头50采集图像。
请再次参阅图7,在某些实施方式中,电子装置100包括可见光摄像头50。处理器30用于控制可见光摄像头50采集图像。
也即是说,步骤S312可以由处理器30实现。
如此,可以利用可见光摄像头50快速地采集图像。
可以理解,电子装置100为了实现功能的多样性,电子装置100可以包括可见光摄像头50以利用可见光摄像头50获得彩色图像。由于可见光摄像头50的相关技术(如控制方法或图像数据处理方法等)比较成熟,利用可见光摄像头50可以快速地采集图像。
请参阅图8,在某些实施方式中,虹膜识别模组20包括红外摄像头24,红外光源22的照明范围、红外摄像头24的视场和可见光摄像头50的视场至少部分重叠。
如此,红外光源22、红外摄像头24和可见光摄像头50可以协同工作。
具体地,红外光源22和红外摄像头24需要协同合作以实现采集虹膜图像,可以将红外光源22和红外摄像头24设置在电子装置100上的同一侧,并且将红外光源22和红外摄像头24相邻设置,从而使得红外光源22发射的红外光经过物体表面后能被红外摄像头24采集到。此外,红外光源22的照明范围、红外摄像头24的视场和可见光摄像头50的视场至少部分重叠可以方便电子装置100采集虹膜图像,例如,可以利用可见光摄像头50采集图像,从而根据图像判断虹膜距离并根据虹膜距离控制红外光 源22和红外摄像头24的启动和关闭,进而在虹膜距离合适时获得虹膜图像。
请参阅图9,在某些实施方式中,电子装置100包括壳体60,壳体60包括前表面62,虹膜识别模组20和可见光摄像头50设置在壳体60内并自前表面62露出。
如此,可以利用电子装置100的壳体60保护虹膜识别模组20和可见光摄像头50和便于虹膜识别模组20和可见光摄像头50进行工作。
具体地,将虹膜识别模组20和可见光摄像头50设置在壳体60内,可以利用壳体60防尘防水的作用来保护虹膜识别模组20和可见光摄像头50,从而避免虹膜识别模组20和可见光摄像头50受到外界因素的损坏和影响其进行正常工作。此外,将虹膜识别模组20和可见光摄像头50自前表面62露出可以方便虹膜识别模组20和可见光摄像头50进行工作,避免影响虹膜识别模组20的红外摄像头24和可见光摄像头50采集光线,从而确保虹膜识别模组20和可见光摄像头50能够高效工作。
请参阅图10,在某些实施方式中,步骤S31包括以下步骤:
S314:控制红外摄像头24采集图像。
请再次参阅图9,在某些实施方式中,处理器30用于:
控制红外摄像头24采集图像。
也即是说,步骤S314可以由处理器30实现。
如此,可以利用红外摄像头24采集图像。
可以理解,在本发明实施方式中,图像用于识别虹膜区域以根据虹膜区域的面积判断虹膜距离,因而对于图像的质量(如色彩、分辨率等)要求不高,因此可以利用红外摄像头24采集图像(灰度图像),从而利用红外摄像头24采集的图像来获取虹膜距离。在一个实施例中,电子装置100包括红外摄像头24而不具备可见光摄像头22,利用红外摄像头24采集图像可以实现本发明实施方式的控制方法。
请参阅图11,在某些实施方式中,步骤S32包括以下步骤:
S322:处理图像以识别是否存在人脸;
S324:在存在人脸时识别虹膜区域;和
S326:在不存在人脸时返回步骤S31。
请再次参阅图2,在某些实施方式中,处理器30用于:
处理图像以识别是否存在人脸;
在存在人脸时识别虹膜区域;和
在不存在人脸时返回采集图像的步骤。
也即是说,步骤S322、S324和S326可以由处理器30实现。
如此,可以减少处理器30的计算量,提高电子装置100的工作效率。
具体地,识别虹膜区域一般要先通过人脸识别,因而识别虹膜区域的计算量一般大于人脸识别的计算量,此外,人脸识别技术相对于识别虹膜区域的技术比较成熟。因此可以通过人脸识别技术快速地处理图像以识别图像中是否存在人脸,在存在人脸时,说明图像中可能包含虹膜区域,进而识别虹膜区域和通过虹膜区域的面积判断虹膜距离;在不存在人脸时,说明图像中不包含虹膜区域,可以直接重新采集图像而不对图像进行虹膜区域的识别以减少处理器30不必要的计算量,从而提高电子装置100的工作效率。
请参阅图12,在某些实施方式中,步骤S33包括以下步骤:
S332:判断虹膜区域的面积是否大于第一预定值并且小于第二预定值;
S334:在虹膜区域的面积大于第一预定值并且小于第二预定值时确定虹膜距离合适;和
S336:在虹膜区域的面积小于等于第一预定值或大于等于第二预定值时确定虹膜距离不合适。
请再次参阅图2,在某些实施方式中,处理器30用于:
判断虹膜区域的面积是否大于第一预定值并且小于第二预定值;
在虹膜区域的面积大于第一预定值并且小于第二预定值时确定虹膜距离合适;和
在虹膜区域的面积小于等于第一预定值或大于等于第二预定值时确定虹膜距离不合适。
也即是说,步骤S332、S334和S336可以由处理器30实现。
如此,可以根据虹膜区域的面积快速、准确地判断虹膜距离是否合适。
可以理解,虹膜区域较小时,说明虹膜远离电子装置100,即虹膜距离较大;在虹膜区域比较大时,说明虹膜接近电子装置100,即虹膜距离较小,因此通过判断虹膜区域的面积可以确定虹膜距离是否合适。具体地,第一预定值小于第二预定值,在虹膜区域的面积大于第一预定值并且小于第二预定值时确定虹膜距离合适,此时获得的虹膜图像纹理信息清晰并且完整;在虹膜区域的面积小于等于第一预定值时虹膜距离过小,此时获得的虹膜图像可能不完整;在虹膜区域的面积大于等于第二预定值时虹膜距离过大,此时获得虹膜图像的纹理信息可能比较模糊。
在某些实施方式中,第一预定值和第二预定值的取值可以根据实验获得并在电子装置100出厂前预设在电子装置100中,不同的电子装置100根据成像能力的不同可能具有不同的第一预定值和第二预定值。虹膜区域的面积可以是指虹膜区域所占的像素的面积,在一个实施方式中,在虹膜区域所占的像素的面积为100*100时,即虹膜区域由10000个像素形成时,对应的虹膜距离为较佳取值。
请参阅图13,本发明实施方式的电子装置100包括虹膜识别模组20、一个或多个处理器30、存储器70以及一个或多个程序。其中一个或多个程序被存储在存储器70中,并且被配置由一个或多个处理器30执行,程序用于执行本发明上述任一实施方式的控制方法的指令。
