本发明的实施方式
以下结合说明书附图及具体实施例对本申请技术方案做进一步的详细阐述。
除非另有定义，本文所使用的所有的技术和科学术语与属于本申请的技术领域的技术人员通常理解的含义相同。本文中在本申请的说明书中所使用的术语只是为了描述具体的实施例的目的，不是旨在于限制本申请的实现方式。本文所使用的术语“及/或”包括一个或多个相关的所列项目的任意的和所有的组合。
在本申请的描述中，需要理解的是，术语“中心”、“上”、“下”、“前”、“后”、“左”、“右”、“竖直”、“水平”、“顶”、“底”、“内”、“外”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本申请和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本申请的限制。在本申请的描述中，除非另有说明，“多个”的含义是两个或两个以上。
在本申请的描述中，需要说明的是，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”应做广义理解，例如，可以是固定连接，也可以是可拆卸 连接，或一体地连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通。对于本领域的普通技术人员而言，可以具体情况理解上述术语在本申请中的具体含义。
红外探测器不仅可以获取场景中的目标信息，并且能够很好地显示隐藏的热目标，不受白天或者黑夜的影响，不受恶劣天气的影响，但是受景物自身辐射特性、系统工作波长、传输距离、大气衰减等因素的影响，红外图像对比度较低，空间相关性强，目标细节的反映能力也比较差。而可见光探测器恰恰可以弥补红外探测器输出图像对比度低，目标细节反映能力差的缺点，但是CCD(电荷耦合器件)探测器通常是“被动”地获取场景中的目标信息，并且在黑夜或者是恶劣的天气情况下，所获得的图像质量会很差，对于可见光图像的这些缺点，红外图像恰好可以弥补。
基于上述研究结果，本申请提供一种双目三光望远镜，采用可见光成像、红外成像得到融合图像，并同时提供激光测距，最终得到的包含可见光信息、红外信息及激光测距信息的综合图像。红外光与可见光图像融合将同一场景的红外图像与可见光图像的信息合并成一幅融合图像，结合测距信息后得到一幅包含更多的信息量的综合图像，从而更适合人眼视觉观察和计算机读取后提取信息。

对应于可见光镜头21，镜头支架26上通过调焦机构27安装有可见光机芯23；对应于红外镜头22，镜头支架26上通过调焦机构27安装有红外机芯24。可见光机芯23用于感应通过可见光镜头21聚焦于此的可见光，并产生可见光图像；红外机芯24用于感应通过红外镜头22聚焦于此的红外光，并产生红外图像。
系统芯片板30包括SOC(System on Chip，系统级芯片)，用于对双目三光望远镜100内的电子元器件进行集中控制，为整机软件功能的载体，与机芯组件20之间通过FPC软排线连接。系统芯片板30上有图像处理芯片，可见光机芯23、红外机芯24及红外测距仪25与系统芯片板30信号连接，系统芯片板30将可见光图像、红外图像融合得到融合图像，并结合测距结果得到包含可见光信息、红外信息及测距信息的综合图像。系统芯片板30将激光测距结果与可见光图像、红外图像或融合图像叠加后的综合图像，输出到显示屏55上进行显示。菜单和其它软件功能在系统芯片板30上可与综合图像进一步叠加后，输出到显示屏55上进行显示。
通过系统芯片板30，双目三光望远镜100具有可见光图像、红外图像、融合图像3种图像模式，在白天使用可见光模式，在纯黑的夜晚使用红外模式，全天候使用融合模式，可解决单一类型望远镜功能不足的缺陷。
请参阅图4，系统芯片板30可提供丰富的对外接口，其上集成有电池仓板31、显示屏电源板32、按键板33、麦克风板34、GPS模块35、电子罗盘36、WiFi模块37及调试接口板38。其中，电池仓板31连接电池仓组60，并用于控制电池仓组60的充放电；显示屏电源板32连接至目镜系统50中的显示屏55，并用于控制显示屏55上显示的信息；按键板33可实现人机交互功能，图示实施例中，对应于外壳40上两个按键区42，设有左右两个按键板共计6个按键，左按键板33包括开机键、激光键、拍照键，右按键板33上包括菜单键和2个方向键；麦克风板34连接至麦克风(图未示)，用于处理麦克风拾取的声音信号；GPS模块35为双目三光望远镜100提供GPS导航定向功能；电子罗盘36可提供南北方向指向功能，为户外使用提供便利；WiFi模块37提供无线信号发射和接收功能，通过手机APP等互联功能，可以在一定的距离通过WiFi互联功能远程观看；调试接口板38用于提供与外部设备连接的接口，例如，调试接口板38可连接接口39，通过接口39连接对应接口类型(例如Type-C、MiniUSB等)的数据线供电、数据导出、固件更新、PAL视频输出等功能，降低了用户的使用难度。
基于系统芯片板30及内部的硬件，双目三光望远镜100可以实现很多软件功能，提供便捷、丰富的用户体验。双目三光望远镜100通过系统芯片板30可实现的功能包括但不限于：开关机；图像模式切换功能(可见光图像、红外图像、融合图像)；屏幕亮度调节；可见光和红外图像亮度、对比度调节；画中画功能；红外热点追踪功能；红外图像极性调节功能；红外图像增强功能；红外图像校正功能；状态图标显示功能；可见光和红外图像、融合图像电子变倍；电子罗盘、GPS定位导航功能；激光测距信息显示；拍照、录像和文件管理、播放和删除；存储卡格式化WiFi实时传输；手机APP互联；电量显示和欠压指示；系统时间显示和设置；录音；恢复系统设置；系统信息查看。
请结合参阅图5至图8，调焦机构27包括旋钮271、调焦螺杆272、调焦螺杆支架273及镜头法兰274。镜头法兰274可相对对应的可见光镜头21、红外镜头22沿光轴方向移动。可见光机芯23、红外机芯24安装在镜头法兰274中，分别与对应的镜头法兰274固定连接。调焦螺杆272沿平行于光轴方向设置，一端可转动地安装在与外壳40固定连接的目镜系统50的后壳51上，另一端可转动地安装于固定在镜头支架26上的调焦螺杆支架273，从而将调焦螺杆272可转动地安装于外壳40内。旋钮271固定连接于调焦螺杆272凸伸出后壳51的末端，镜头法兰274通过螺纹连接至调焦螺杆272的另一末端。
如图6中所示，调焦螺杆支架273连接于调焦螺杆272直径减小处，且两端装有卡簧276进行限位。2个卡簧276与调焦螺杆支架273配合在一起对调焦螺杆272的移动起限位作用，将调焦螺杆272约束在与调节螺杆支架273连接处，使调焦螺杆272在转动的时候不会发生轴向移动。
调焦机构27还包括消隙弹簧275，镜头法兰274上设有与调焦螺杆272对应的螺纹孔，消隙弹簧275放置在螺纹孔内，调焦螺杆272的前端与消隙弹簧275相抵。调焦螺杆272的外螺纹与镜头法兰274的内螺纹配合时，内外螺纹之间的间隙通过消隙弹簧275消除，消隙弹簧275的弹力对镜头法兰274相对调焦螺杆272的位移进行调节，保证调焦的精确性。以对可见光镜头21进行调焦为例，用手指拨动旋钮271，调焦螺杆272会随旋钮271一起转动，调焦螺杆272转动会带动与调焦螺杆272螺纹连接的镜头法兰274相对沿调焦螺杆272移动，可见光机芯23则随同镜头法兰274沿调焦螺杆272移动，与可见光镜头21之间在光轴方向上的距离发生变化，从而起到调焦对焦的作用。如图7中所示，可见光镜头21的镜头筒211在与镜头法兰274连接处凸设3个定位销钉2111(整圈均布3个)，3个定位销钉2111限位在对应的3条定位导向槽2741 内，导向槽2741沿光轴方向设置以导引镜头法兰274的移动方向，从而保证红外机芯24相对于可见光镜头21只能在导向槽2741的导向和限位作用下只能沿光轴平行移动而不会转动。
同理，用手指拨动对应与红外镜头22、红外机芯24的旋钮271，调焦螺杆272一同转动带动镜头法兰274和可见光机芯24移动，从而起到调焦对焦的作用。
外壳40仿照人手握持方式，设计为C字形弧线握持机身，即外壳40两侧的握持区41呈C字形弧线，以方便握持。人手正常放松情况下，大致呈现为C字形手的基本位置有正中、尺侧偏、挠侧偏、背侧偏和掌测屈五种，正中位置是手的自然位置，在此位置，手腕的受力状态最佳。C字形弧线握持方式，保证了手和产品以及按键区42均保持在中部，保证手腕处于顺直状态，避免掌部组织受压力。且按键区42中的按键的高度符合人体握持手势的弧度，以及按键的大小、外形贴近用户手指形状，手感舒适，且不容易出现误操作。握持区41可设咬花面手胶来增加手掌与产品的摩擦力，从而达到防滑效果。
请结合参阅图9至图11，目镜系统50包括与外壳40固定连接的后壳51，后壳51上安装有两套目镜52，每套目镜52通过目镜法兰53及密封圈54从外侧安装到后壳51上对应的目镜孔511中，目镜法兰53的内侧通过导向块57和压环58锁紧固定。每套目镜52对应的显示屏55通过屏幕压块56固定到目镜法兰53上且位于目镜52前方。
具体地，目镜法兰53的周向向外延伸出挡片531，挡片531大于目镜孔511且抵靠在后壳51的外侧，从而将目镜孔511遮挡并约束目镜法兰53在前后方向的位置。导向块57上具有与目镜孔511形状相同的导向孔571且设置在目镜孔511的内侧，目镜法兰53前端的连接端532从目镜孔511、导向孔571中穿过，并与压环58通过螺纹连接，压环58的后端面与导向块57的前端面相接触，由于目镜法兰53的挡片531与压环58分别位于后壳51的内外两侧，因此可通过螺纹调节压环58在目镜法兰53上安装的位置，实现对目镜法兰53与后壳51之间的松紧度进行调节，从而使目镜法兰53可带动目镜52在目镜孔511内移动，实现对瞳距进行调节，保证瞳距调节后的视觉效果。压环58的侧壁上还可开设锁紧孔，通过锁紧销插入锁紧孔内顶抵连接端532的壁面，压环58无法旋动，从而且在连接端532上的位置进行锁紧，用于瞳距调整完成后锁紧防止松动。后壳51的外侧设有刻度标线512，刻度标线512位于两个目镜孔511之间，用于指示目镜法兰53(及其内的目镜52)当前位置及移动距离。例如，刻 度标线512的相邻刻度线之间的间隔可设为1mm，按箭头方向移动目镜法兰53以每移动一个刻度线则目镜52的移动1mm来作为参照来调节两套目镜52之间的距离，从而可适配不同瞳距的用户，让用户获得最佳视觉效果。由于目镜52和对应的显示屏57一同安装在目镜法兰53上，当通过移动目镜法兰53调节两目镜52之间的距离时，目镜法兰53带动显示屏55分别沿着导向孔571一起移动，可以保证显示屏55的屏幕中心一直与目镜52的光轴保持一致，不会因为瞳距调节使画面超出目镜观察范围。
导向块57可采用如PTFE(聚四氟乙烯)材质，具有耐磨、自润滑等特性，保证产品可靠性。调节瞳距的松紧可以通过导向块57、压环58调整，结构装配简单。
电池仓组60内安装电池为整机供电，图示实施中，电池仓组60内安装2节18650mAh电池。此外，双目三光望远镜100也可以通过接口39外接数据线来进行供电。接口39的类型不限于前文例举的Type-C、MiniUSB，亦可根据需要同时设置两种或辆以上的接口，对此不作限定。为获得更低的照度，除摄取可见光外，可见光机芯23也需要摄取一些红外光，而不同波长的红外光都被摄取会对可见光成像造成一定的影响，所以要采用可滤除不需要的红外光而保留需要的红外光的滤光片。通常采用IR-CUT双滤镜，在摄像头镜头组里内置了一组滤镜，当镜头外的红外感应点侦测到光线的强弱变化后，内置的IR-CUT双滤光片切换器能够根据外部光线的强弱随之自动切换，使可见光图像达到最佳效果。由于IR-CUT双滤光片切换器的实现需要一个微电子电机驱动电路机构以及两片或多片滤光片，而且在实现上难度较大价格也更高，所以会导致产品的体积、重量、功耗以及性价比有所增加。请参阅图12和图13，可见光镜头21包括镜头筒211以及设置在镜头筒211内的透镜212和双带通滤光片213，多个透镜212和双带通滤光片213沿光轴布置，相邻的透镜212之间、透镜212与双带通滤光片213之间设有隔圈214，以将相邻的镜片隔离。最前端的透镜212设有密封圈215和压圈216，将透镜212密封在镜头筒211内。多个透镜212形成透镜组将光线进行聚焦并经镜片透射。双带通滤光片213对来自前端透镜212的光进行过滤后射向可见光机芯23。
双带通滤光片213为具备两个带通的单个滤光片，只用一片滤光片实现两个特定波段的截取，能够选择两个或以上区域范围内的波段通过。请结合参阅图13，双带通滤光片213允许部分可见光波段(第一波段)以及部分红外光波段(第二波段)通过。第一波段为可见光波段420～660nm，通过率T为50％以 上；第二波段为红外光波段930～970nm，通过率T为85％以上。双带通滤光片213通过镀膜实现双带通，双带通滤光片213的镀膜要求详细参数如下：
420～620nm：最小通过率Tmin≥85％，平均通过率Tave≥90％；
650±10nm：通过率T＝50％；
700～850nm：通过率T＜3％；
930～970nm：通过率T＞85％；
1100～1200nm：最大通过率Tmax≤4％。
双带通滤光片213对进入可见光机芯23的光线进行滤光使特定波段的可见光和红外光通过。
可见光机芯23中具有图像传感器及图像处理模块，图像处理模块实时接收图像传感器输出的图像信号并对图像传感器传输过来的图像信号进行处理，例如白平衡处理、曝光处理以及颜色校正等。双带通滤光片213与可见光机芯汇中的图像处理模块一同可实现双带通切换，以适应日间模式与夜间模式。
具体地，在日间模式下(日间使用时)，第一波段(650nm波段范围)和第二波段(940nm波段范围)的光都会通过双带通滤光片213，被图像传感器感测，图像处理模块收到图像信号后通过图像算法会把第二波段的光滤掉，仅保留第一波段的光的图像，避免第二波段的光影响图像的色彩还原度；在夜间模式下(夜间使用时)，第一波段的光在夜间几乎没有，通过双带通滤光片213的基本只有第二波段的光，图像处理模块在处理收到图像信号时不过滤第一波段的光的图像。
图像处理模块可通过光传感器感应外部场景的光线明暗变化判断外部场景是属于日间场景还是夜间场景，从而判断是否需要将收到的来自图像传感器的图像信号中的第二波段的光滤掉。
为了提升双目三光望远镜100的夜间彩色成像效果，可通过增加红外光源来增强光线照度。具体地，请参阅图14和图15，双目三光望远镜100可在外壳40上可拆卸地安装红外手电筒70。红外手电筒70通过手电筒安装架80安装至外壳40的底部。
手电筒安装架80包括抱箍81及连接片82，抱箍81可套设于红外手电筒70的外围，通过锁紧抱箍81将红外手电筒70固定到抱箍81上，连接片82一端与抱箍81固定，另一端可通过紧固件锁紧至外壳40的底部。
红外手电筒70可采用IR 940nm补光手电筒，在通电后发出940nm的红外光。红外手电筒70安装在外壳40的底部且位于红外镜筒12、红外镜头22的下方。在通电后沿平行于红外镜头22的光轴方向向目标方向发出940nm的红外光，增强夜间使用时的光线照度。红外手电筒70为独立部件/配件，可使用自身的电源，不占用内部的电池仓组60的电源供电，不影响续航能力。而且，红外手电筒70可从外壳40上拆卸，不占用内部的空间，也能在不需要使用时拆下以减轻重量。
在夜间照明不足的情况下，可以安装上红外手电筒70增强照度，从而观察到清晰的彩色图像。红外手电筒70也可以通过自行拆装更换不同功耗的红外手电筒，通过照射距离不同以适应不同的场景使用，提高可见光夜间彩色成像的效果，保证光学成像质量。
上述双目三光望远镜100的工作过程如下：从双目镜筒10射入的光线分别通过可见光镜头21和红外镜头22聚焦后投射到可见光机芯23和红外机芯24；可见光机芯23和红外机芯24感应成像得到的可见光图像和红外图像；可见光图像和红外图像的图像数据输入到系统芯片板30图像处理芯片进行数据处理；激光测距仪25通过激光窗口14发射和接收激光，在激光测距仪25进行数据处理得到测量结果；最终数据都输出到目镜系统50的显示屏55上。人眼通过目镜系统50的眼罩，可以看到显示屏55上的图像信息和界面信息等。
在使用过程中，通过调节调焦机构27可分别对可见光成像、红外成像进行调焦对焦；通过调节目镜系统50的目镜视度和瞳距，来调整观察的图像效果；通过手电筒连接架80连接安装红外手电筒70，在夜间照明效果不良时可以使用增强可见光成像效果。

本申请的双目三光望远镜具有可见光、红外物镜手动调焦功能，通过调整机芯(可见光机芯、红外机芯)与镜头(可见光镜头、红外镜头)的相对位置来实现对焦功能，用手指拨动旋钮，调焦螺杆会一起转动，调焦螺杆转动会带动镜头法兰及机芯相对镜头移动，从而起到调焦对焦的作用。因取消镜头内部调焦从而使镜头结构简化，重量减轻，整个功能结构不需要额外增加整机空间，功能机构上需要密封的位置只需要普通的密封圈即可实现；整机在使用过程中，对焦只要单个手指即可完成，非常方便。
本申请的双目三光望远镜具有瞳距可调功能，通过将目镜固定目镜法兰上，增加导向块实现瞳距可调，调节瞳距的松紧可以通过导向块压环调整。结构装配简单，不需要螺丝锁付，没有复杂的零件，整机外形不受限制，可设计不同的外形，不影响产品内部空间布局，有更多的空间增加其他功能组件。目镜法兰上通过安装密封圈，可实现整机密封，提供较高的密封等级。
本申请的双目三光望远镜具有日夜两用功能，采用双带通滤光片来替换IR-CUT双滤光片切换器，日间模式图像处理模块滤掉红外光的图像以获得清晰的图像，夜间模式下可感应红外光得到更低的照度，具有性价比高、体积小、结构简单、稳定性高的特点，能够提高夜间彩色成像的效果，保证光学成像质量。为了提升夜间彩色成像效果，可同时使用红外手电筒来增强光线照度，再使用图像处理算法来使可见光成像效果最佳，提高可见光夜间彩色成像的效果，保证光学成像质量。
