本图像信息采集装置1有以下拍摄模式：
普通模式
传输模块2监听信号，外部终装置发出普通拍摄模式指令给控制器3，切换成普通模式，模式管理模块301启动第一摄像头4，第二摄像头4置于非工作状态，第一摄像头内的滤光片切换器根据模式管理模块301的切换指令控制切换至红外截止滤光片正常工作，当所拍摄物体的光反射进镜头时，红外截止滤光片将吸收过滤掉红外线，使得图像传感器CCD或CMOS接收到可见光光谱范围 内的光线并将其转化成图形电信号，经图形处理模块32处理后通过传输模块2传输至外部装置。此时，第一摄像头4也即处于可见光拍摄模式下。
可见光摄像头进行拍摄时，模式管理模块301检测当前环境光是否需要开启可见光灯补光，补光模块304根据检测结果进行可见光补光，使摄像头有较好的宽动态，拍摄到比较清晰的图像。
本模式下的对焦模块303切换摄像头4对焦范围为大于等于1mm。
本模式下，可以根据拍摄信号中的加密指令判断是否需要对图像数据进行加密，对拍摄好的图像数据进行加密后方可进行传输，加密方式只需对应的解密方式能完整解密出正确的信息即可，本发明不做限制。
双目夜视模式：
传输模块2监听信号，外部装置发出夜视拍摄模式指令给控制器3，切换成双目夜视模式，模式管理模块301同时启动第一摄像头4和第二摄像头4，第一摄像头4和第二摄像头4内置的滤光片切换器根据模式管理模块31的切换指令控制切换至全光谱透镜正常工作，夜晚当所拍摄物体的光反射进镜头时，第一摄像头4和第二摄像头4的图像传感器CCD或CMOS接收到全部光谱范围内的光线并将其转化成图形电信号，经图形处理模块302处理后通过传输模块2同时传输至外部装置。此时，第一摄像头4和第二摄像头4均处于红外拍摄模式下。
模式管理模块301检测当前环境光是否需要开启红外补光，补光模块304根据检测结果进行红外光补光，使摄像头有较好的宽动态，拍摄到比较清晰的图像。
本模式下的对焦模块303切换第一摄像头4和第二摄像头4对焦范围为大于等于1mm。
本模式下，可以根据拍摄信号中的加密指令判断是否需要对图像数据进行加密，对拍摄好的图像数据进行加密后方可进行传输，加密方式只需对应的解密方式能完整解密出正确的信息即可，本发明不做限制。
3D视频模式：
本发明图像信息采集装置1为双目摄像头，结构为仿人眼的构造，具体表现为水平分布且二者之间有若干距离，即拍摄的图片有一定的左右视野差距，与人眼成像构造相同。
传输模块2监听信号，外部装置发出3D拍摄模式指令给控制器3，切换成3D视频模式，模式管理模块301同时启动第一摄像头4和第二摄像头4，两摄像头4内的滤光片切换器根据模式管理模块301的切换指令各自控制切换至红外截止滤光片正常工作，当所拍摄物体的光反射进镜头时，图像传感器CCD或CMOS接收到可见光的光线并将其转化成图形电信号，经图形处理模块302处理后通过传输模块2传输至图像信息采集装置1外的显示屏进行简单预览，也即两摄像头4全部切换到可见光模式下。
将两个摄像头4拍摄的图像同步传输到图像处理模块302进行处理，当前为左右3D视频拍摄模式，图像处理模块302不对图像作处理，直接把图像数据同步发送到输出模块；用户可以利用拍摄的图像数据进行后续的加工处理，如用户使用外部装置通过传输模块2接收到图像数据后，把左边的摄像头4拍摄的图像显示在屏幕左边，把右边摄像头4拍摄的图像显示在屏幕右边，通过左右3D眼镜，左眼可以看见左边摄像头4拍摄的图像，同时右眼可以看见右边摄像头4拍摄的图像，由于两个摄像头4拍摄的图片分别作用于人眼成像并实现3D视觉效果。
上述两个摄像头4进行拍摄时，模式管理模块31检测当前环境光是否需要开启可见光补光，补光模块304根据检测结果进行可见光补光，使摄像头4有较好的宽动态，拍摄到比较清晰的图像。
本模式下的对焦模块303切换摄像头4对焦范围为大于等于1cm。
本模式下，可以根据拍摄信号中的加密指令判断是否需要对3D视频图像数据进行加密，对拍摄好的图像数据进行加密后方可进行传输，加密方式只需对应的解密方式能完整解密出正确的信息即可，本发明不做限制。
3D建模模式：
传输模块2监听信号，外部装置发出3D建模模式指令给控制器3，切换成3D视频模式，模式管理模块301同时启动第一摄像头4和第二摄像头4，两摄 像头4内的滤光片切换器根据模式管理模块301的切换指令控制各自切换至红外截止滤光片正常工作。即两个摄像头4切换至可见光模式，摄入模块中的两个摄像头4当前均为接收可见光的摄像头。
图像处理模块302将图像数据传输到传输模块2进行交互，用户可以利用拍摄的图像数据进行后续的加工处理。
本发明为双目摄像头，具体表现为摄像头水平分布且二者之间有若干距离，即存在主视点焦距和次视点焦距，具备立体照相机的必须条件，而立体照相机的三维建模方式为公知方式，本发明不再阐述其中的具体成像原理。可见光摄像头进行拍摄时，模式管理模块301检测当前环境光是否需要开启可见光补光，补光模块304根据检测结果进行可见光补光，使摄像头4有较好的宽动态，拍摄到比较清晰的图像。
本模式下的对焦模块303切换摄像头4对焦范围为大于等于1cm。
本模式下，可以根据拍摄信号中的加密指令判断是否需要对3D建模图像数据进行加密，对拍摄好的图像数据进行加密后方可进行传输，加密方式只需对应的解密方式能完整解密出正确的信息即可，本发明不做限制。
单目人脸识别图像采集模式：
传输模块2监听信号，外部装置发出单目人脸识别图像采集模式指令给控制器3，切换成单目活体人脸识别图像采集模式，模式管理模块301启动第一摄像头4，并把第二摄像头4置于非工作状态，第一摄像头4内的滤光片切换器根据模式管理模块301的切换指令控制切换至红外吸收滤光片正常工作，即接收可见光模式的摄像头。
本模式下，人脸图像信息采集方法是采用上述的图像采集装置1，按照以下步骤进行人脸识别：
S41：启动第一摄像头4，并把第二摄像头4置于非工作状态；
S42：控制器3切换第一摄像头4至可见光拍摄模式；
S43：抓取近第一摄像头4的可见光图像数据，并输出非加密的可见光图像数据至显示屏给用户预览；
S44：判断可见光图像是否存在活体人脸，图像处理模块302检测到步骤S43可见光图像中存在人脸，保持可见光图像并运行步骤S45，否则运行步骤S43；
S45：判断近红外人脸图像和/或可见光人脸图像是否符合生物图像识别拍摄要求，主要由图像处理模块302判断图片人脸大小、图片质量、人脸关于XYZ轴的角度是否符合标准，如果是运行步骤S46，否则进行步骤S43；
S46：模式管理模块301控制第一摄像头4内的滤光片切换器切换至近红外窄带滤光片正常工作，即接收近红外光模式的摄像头；
S47：模式管理模块301检测当前环境光是否需要开启近红外补光，补光模块304根据检测结果进行近红外补光；
S48：抓取近第一摄像头4的近红外光图像数据，图像处理模块302检测近红外图像中是否存在人脸，则认为是活体人脸，保持近红外图像并运行步骤S49，否则认为非活体人脸(如人脸照片)，运行步骤S42；
S49：图像处理模块302利用人脸识别算法判断步骤S44的可见光图像和步骤S48的近红外图像的相似度，如果该相似度超过设定阈值，则认为是同一个人，则执行步骤S50，否则认为不是同一个人的非法用户，执行步骤S42；
S50：判断模式指令中是否包含加密请求，如果包含，则控制器3把步骤S44保存的可见光人脸图像数据和/或步骤S48保存的近红外人脸图像数据传送到加密模块305进行加密，运行步骤S51，否则运行步骤S52；
S51：控制器3把加密后的可见光生物图像数据和/或近红外生物图像数据通过传输模块2发送至外部装置；
S52：控制器3把未加密的可见光生物图像数据和/或近红外生物图像数据通过传输模块2发送至外部装置。
步骤S47中第一摄像头4的人脸检测使用近红外波长为700～1100nm，优选为850nm的光谱。
由于可见光人脸检测容易受到照片、雕塑等的假冒物体影响，使用近红外光源拍摄成像则避免了这种假冒的情况，所以近红外图像人脸检测的技术优势比可见光人脸检测更大，并且由于不受环境光影响，拍摄的图像质量更加高，人脸特征点也更加清晰准确，具有更高的可用性，提高活体人脸检测的准确度，这是一般普通的网络摄像头所不具备的功能。
此外，图像处理模块302还将摄像头4所拍摄的符合人脸拍摄需求的图像进行传输前的准备，如根据拍摄信号中的加密指令判断是否需要对图像数据进行加密，对拍摄好的图像数据进行加密后方可进行传输，加密方式只需对应的解密方式能完整解密出正确的信息即可，本发明不做限制。
最后，利用传输模块2，将加密后的图像数据进行数据传输，发送到外部装置，用户可以利用拍摄的图像数据进行后续的加工处理。
本模式下的对焦模块303切换摄像头对焦范围为10～100cm。
活体人脸识别图像采集模式下，采用本发明的生物图像信息采集装置的方法也可以应用于活体虹膜识别图像采集、活体指静脉识别图像采集、活体掌静脉识别图像采集及活体耳朵识别图像采集中。

双目人脸识别图像采集模式：
传输模块2监听信号，外部装置发出双目人脸识别图像采集模式指令给控制器3，切换成双目活体人脸识别图像采集模式，模式管理模块301同时启动第一摄像头4和第二摄像头4，第二摄像头4内的滤光片切换器根据模式管理模块301的切换指令控制切换至红外截止滤光片正常工作，即接收可见光模式的摄像头；与此同时，第一摄像头4内的滤光片切换器根据模式管理模块301的切换指令控制切换至近红外窄带滤光片正常工作，即接收近红外光模式的摄像头。
本模式下，人脸图像信息采集方法是采用上述的图像采集装置1，如图6，按照以下步骤进行人脸识别：
(51)启动两个摄像头4，两个摄像头同步输出图像数据；
(52)控制器3切换第一摄像头4至近红外拍摄模式，同时切换第二摄像头4至可见光拍摄模式；
(53)抓取近第一摄像头4的近红外图像数据，同时抓取第二摄像头4的可见光图像数据，并输出非加密的近红外图像数据和可见光图像数据至显示屏给用户预览；
(54)判断近红外图像是否存在活体人脸，利用近红外结合补光的方法，图像处理模块302检测到步骤(53)近红外图像中存在人脸，则认为是活体人脸，运行步骤(55)，否则认为非活体人脸(如人脸照片)，运行步骤(53)；
(55)判断近红外人脸图像和/或可见光人脸图像是否符合生物图像识别拍摄要求，主要由图像处理模块302判断图片人脸大小、图片质量、人脸关于XYZ轴的角度是否符合标准，如果是运行步骤(56)，否则进行步骤(53)；
(56)判断模式指令中是否包含加密请求，如果包含，则控制器3把拍摄好的可见光人脸图像数据和/或近红外人脸图像数据传送到加密模块305进行加密，运行步骤(57)，否则运行步骤(58)；
(57)控制器3把加密后的可见光生物图像数据和/或近红外生物图像数据通过传输模块2发送至外部装置；
(58)控制器3把未加密的可见光生物图像数据和/或近红外生物图像数据通过传输模块2发送至外部装置。
步骤(52)中第一摄像头4的人脸检测使用近红外波长为700～1100nm，优选为850nm的光谱。
由于可见光人脸检测容易受到照片、雕塑等的假冒物体影响，使用近红外光源拍摄成像则避免了这种假冒的情况，所以近红外图像人脸检测的技术优势比可见光人脸检测更大，并且由于不受环境光影响，拍摄的图像质量更加高，人脸特征点也更加清晰准确，具有更高的可用性，提高活体人脸检测的准确度，这是一般普通的网络摄像头所不具备的功能。
此外，图像处理模块302还将摄像头4所拍摄的符合人脸拍摄需求的图像进行传输前的准备，如根据拍摄信号中的加密指令判断是否需要对图像数据进行加密，对拍摄好的图像数据进行加密后方可进行传输，加密方式只需对应的解密方式能完整解密出正确的信息即可，本发明不做限制。
最后，利用传输模块2，将加密后的图像数据进行数据传输，发送到外部装置，用户可以利用拍摄的图像数据进行后续的加工处理。
本模式下的对焦模块303切换摄像头对焦范围为10～100cm。

低照度环境双目人脸识别图像采集模式：
传输模块2监听信号，外部装置发出双目人脸识别图像采集模式指令给控制器3，切换成双目活体人脸识别图像采集模式，模式管理模块301同时启动第一摄像头4和第二摄像头4，第二摄像头4内的滤光片切换器根据模式管理模块301的切换指令控制切换至全光谱透镜正常工作，即接收红外光模式的摄像头；与此同时，第一摄像头4内的滤光片切换器根据模式管理模块301的切换指令控制切换至近红外窄带滤光片正常工作，即接收近红外光模式的摄像头。
本模式下，人脸图像信息采集方法是采用上述的图像采集装置1，如图7，按照以下步骤进行人脸识别：
(61)启动两个摄像头4，两个摄像头同步输出图像数据；
(62)控制器3切换第一摄像头4至近红外拍摄模式，同时切换第二摄像头4至红外光拍摄模式；
(63)抓取近第一摄像头4的近红外图像数据，同时抓取第二摄像头4的红外光图像数据，并输出非加密的近红外图像数据和红外光图像数据至显示屏给用户预览；
(64)判断近红外图像是否存在活体人脸，利用近红外结合补光的方法，图像处理模块302检测到步骤(63)近红外图像中存在人脸，则认为是活体人脸，运行步骤(65)，否则认为非活体人脸(如人脸照片)，运行步骤(63)；
(65)判断近红外人脸图像和/或红外光人脸图像是否符合生物图像识别拍摄要求，主要由图像处理模块302判断图片人脸大小、图片质量、人脸关于XYZ轴的角度是否符合标准，如果是运行步骤(66)，否则进行步骤(63)；
(66)判断模式指令中是否包含加密请求，如果包含，则控制器3把拍摄好的可红外人脸图像数据和/或近红外人脸图像数据传送到加密模块305进行加密，运行步骤(67)，否则运行步骤(68)；
(67)控制器3把加密后的红外光生物图像数据和/或近红外生物图像数据通过传输模块2发送至外部装置；
(68)控制器3把未加密的红外光生物图像数据和/或近红外生物图像数据通过传输模块2发送至外部装置。
步骤(62)中第一摄像头4的人脸检测使用近红外波长为700～1100nm，优选为850nm的光谱。
由于在低照度环境，尤其是黑夜的情况下，由于光线的不足无法形成可作人脸识别用的可见光图像，因此，通过红外光代替可见光，达到在低照度环境的人脸识别的图像采集工作。
此外，图像处理模块302还将摄像头4所拍摄的符合人脸拍摄需求的图像进行传输前的准备，如根据拍摄信号中的加密指令判断是否需要对图像数据进行加密，对拍摄好的图像数据进行加密后方可进行传输，加密方式只需对应的解密方式能完整解密出正确的信息即可，本发明不做限制。
最后，利用传输模块2，将加密后的图像数据进行数据传输，发送到外部装置，用户可以利用拍摄的图像数据进行后续的加工处理。
本模式下的对焦模块303切换摄像头对焦范围为10～100cm。
活体人脸识别图像采集模式下，采用本发明的生物图像信息采集装置的方 法也可以应用于活体虹膜识别图像采集、活体指静脉识别图像采集、活体掌静脉识别图像采集及活体耳朵识别图像采集中。
活体虹膜识别图像采集：使用的近红外光谱的波长优选为850nm，摄像头拍摄对焦范围为1‐20厘米；

活体耳朵识别图像采集：使用的近红外光谱的波长优选为850nm，摄像头拍摄对焦范围为1‐50厘米。
全焦点距离拍摄模式
全焦点距离影像的拍摄，利用所述的两个摄像头4，其中一个为近焦点距离，另一个为远焦点距离，进行拍摄图像，拍摄的图像数据通过传输模块2传输到外部装置，外部装置通过第三方软件把近焦点距离摄像头拍摄的图像和远焦点距离摄像头拍摄的图像，融合成一幅全景图像；或者，将近焦点距离摄像头拍摄的图像和远焦点距离摄像头拍摄的图像经过控制器3的图像处理模块302处理，融合成一幅全景图像，再通过传输模块2传输到外部装置。
单目摄像头在对焦的时候，由于只有一个焦点距离，如果焦点距离较近，则能清晰地拍摄近距离的物体，而远距离物体成像则模糊图像；相反，如果焦点距离较远，则能拍摄近距离的物体变得模糊，而远距离物体成像则变得清晰图像，二者不能得兼。利用双摄像头各自焦点距离不同拍摄图像，然后融合成一幅图像，则能很好解决了清晰拍摄近距离物体的时候也能清晰拍摄远距离物体的问题。
传输模块2监听信号，外部装置发出全焦点距离拍摄模式指令给控制器3，切换成全焦点距离拍摄模式，模式管理模块301根据控制信号切换至对应的拍摄模式，两个摄像头4切换至可见光模式。模式管理模块301根据指令分别控制两个摄像头4中的光谱滤光片，使两个红外截止滤光片正常工作，CCD或CMOS只能利用可见光光谱范围内的光线，由此，将两个摄像头4切换至可见光模式。
模式管理模块301控制第一摄像头4的对焦模块303的对焦距离为拍摄物体的实际距离，如果第一摄像头4的对焦模块303的对焦距离为近距离，则控制第二摄像头4的对焦模块303的对焦距离为远距离；同理，如果第一摄像头4的对焦模块303的对焦距离为远距离，则控制第二摄像头4的对焦模块303的对焦距离为近距离。
当光反射进镜头时，使得一个图像传感器CCD或CMOS接收到近距离清晰远距离模糊的可见光图像，另一个图像传感器CCD或CMOS接收到近距离模糊远距离清晰的可见光图像，经图形处理模块302处理后通过传输模块2传输至外部装置。
可见光摄像头进行拍摄时，模式管理模块31同时检测是否需要可见光补光，并根据检测结果进行可见光补光，使摄像头有较好的宽动态，拍摄到比较清晰的图像。图像处理模块302将图像数据传输到传输模块2进行交互，用户可以利用拍摄的图像数据进行后续的加工处理。
本模式下，根据拍摄信号中的加密指令判断是否需要对图像数据进行加密，对拍摄好的图像数据进行加密后方可进行传输，加密方式只需对应的解密方式能完整解密出正确的信息即可，本发明不做限制。
开发者拍摄模式
传输模块2监听信号，外部装置发出开发者拍摄模式指令给控制器3，切换成开发者拍摄拍摄模式。
在此模式下，开发者可以通过传输模块2查询关于每个摄像头4以及各自的对焦模块303、补光模块304和滤光片切换器的工作状态；并且可以通过传输模块2改变每个摄像头4以及各自的对焦模块303、补光模块304和滤光片切换器的工作状态。
图像传感器CCD或CMOS在开发者自定义的工作光谱、对焦距离和补光环境，形成与之相应的电子图像信号，经过传输模块2把两个摄像头4的图像信号同步传输到外部装置，这样开发者可以根据实际应用需要对本图像采集装置进行开发利用。
本发明中的多功能双目摄像头允许摄像头切换成不同的拍摄模式，不需要 额外的调整即可满足多种功能模式的需求，且在摄像头内部具有加密功能，现有的摄像头产品绝大部分无法实现此需求，显见本发明具有非常先进的优势。

(b7)判断近红外图像是否存在活体人脸，即图像处理模块302检测近红外图像中是否存在人脸，如果是，则认为是活体人脸，保持近红外人脸图像运行步骤(b8)，否则认为非活体人脸(如人脸照片)，运行步骤(b1)；

如果该相似度超过设定阈值，阈值为不小于0.8不大于1的值，则认为是同一个人，运行步骤(b10)，否则认为不是同一个人，运行步骤(b1)；
(b10)控制器把拍摄好的可见光人脸图像数据和/或近红外人脸图像数据通过传输模块发送至外部装置，或者，控制器把拍摄好的红外光人脸图像数据和/或近红外人脸图像数据通过传输模块发送至外部装置。

判断所述控制器的模式指令中是否包含加密请求，如果包含，则控制器把拍摄好的图像数据传送到所述加密模块进行加密，加密后的图像数据通过所述传输模块被发送至所述外部装置；否则，控制器把未加密的图像数据通过传输模块发送至外部装置。
