 附图说明
为了更清楚地说明本发明实施例中的技术方案，下面将对实施例描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其它的附图，其中：
图1是本发明成像组件的结构示意图。
 本发明的实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅是本发明的一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其它实施例，都属于本发明保护的范围。
如图1所示，成像组件100包括红外光感应器1、可见光感应器2以及波长选择器3。波长选择器3独立设置于红外光感应器1及可见光感应器2之间，波长选择器3通过波长选择从入射光中分离出红外光传送至红外光感应器1，从入射光中分离出可见光传送至可见光感应器2。可见光感应器2所在平面与入射光的方向大致垂直，红外光感应器1所在平面与入射光的方向大致平行。
当入射光进入成像组件100时，入射光中的可见光、红外光经过波长选择器3分别被传送至不同的方向，可见光感应器2能够接收可见光，红外光感应器1能够接收红外光。通过这样的设计，可见光与红外光共享了部分光线路径，从而减小了视差，提高了采集信号的精确度，进而提升了图像的清晰度。同时，成像组件的光学窗口不需要设置多个，所有的感应器都共用同一来源的光线，从而可以减小了视差以及图像的失真。
在本实施例中，波长选择器3是反光镜，反光镜的表面设置仅容可见光通过的涂层，红外光无法通过涂层并且被反光镜反射到红外光感应器1。在其它实施例中，也可以在反光镜表面设置另一种材料的涂层，另可见光无法通过且被反射到可见光感应器2，红外光可以通过涂层进入红外光感应器1。在其它实施例中，也可以采用其它的结构来实现可见光与红外光的分离，例如在镜子上设置其它材料或者微型装置。
在其它实施例中，波长选择器3也可以是三棱镜，三棱镜可以将入射光中的可见光、红外光分别折射至不同方向，这样的设计可以减少可见光与红外光之间的相互干扰，从而不影响红外光感应器1、可见光感应器2的探测结果。
本实施例中，成像组件100的波长选择器3将红外光、可见光分离，并且实现了精确分离、产生较小的光损耗，红外光、可见光来源于同一束入射光，从而减少了误差以及降低了成像的失真。
如图1所示，成像组件100还包括导光元件4，波长选择器3固定于导光元件4。导光元件4呈立方体，包括与入射光的方向大致平行的第一平面41以及与入射光的方向大致垂直的第二平面42。红外光感应器1与第一平面41相邻设置，可见光感应器2与第二平面42相邻设置。入射光的方向与波长选择器3形成夹角A，A=45°,可见光的传输方向与红外光的传输方向相互垂直。通过这样的设计可以提高采集信号的精确度，并且提高图片质量。
导光元件4由树脂或者其它材料制成。导光元件4有利于波长选择器3的安装，且有利于入射光的传输、减少外部干扰因素，从而提高采集信号的精确度，并且在实际使用中提高图片质量。
如图1所示，成像组件100还包括采集光线的镜头5，光线被镜头5折射后形成集中的平行的入射光进入导光元件4。这样的设计可以使入射光的光束更集中，传输至红外光感应器1的红外光、传输至可见光感应器2的可见光也更集中，减少了光损耗。
在其它实施例中，红外光感应器1为ToF镜头（飞行时间镜头）。ToF镜头在红外光波段工作，因此ToF镜头可以接收红外光，ToF镜头可以实现摄影以及AR功能，也可以用来测试距离、高度及宽度。可见光感应器2为RGB镜头，RGB镜头在可见光波段工作，ToF镜头与RGB镜头共享了同一来源的光线以及一段共同的光学路径，可见光与红外光的波段分界非常清晰且产生很小的光损耗，RGB镜头与ToF镜头共同配合提升图像的高清度，尤其在AR摄像功能上效果更好。且由于只需要一个光源窗口，整个装置的体积也相应降低。
一种摄像机，包括成像组件100，其包括红外光感应器1、可见光感应器2以及波长选择器3，波长选择器3独立设置于红外光感应器1及可见光感应器2之间，且可从入射光中分离出红外光传送至红外光感应器1、可见光传送至所述可见光感应器2。
以上所述的仅是本发明的实施方式，在此应当指出，对于本领域的普通技术人员来说，在不脱离本发明创造构思的前提下，还可以做出改进，但这些均属于本发明的保护范围。
