发明内容
【技术方案要解决的技术问题】
要解决单眼立体影像的两眼看2D视频而不能看到3D立体影像的问题，要克服，已公开的中国专利CN104246579A，因缺少两个不同画面的2D影像，而使得眼镜立体感效果不足、不能实用的缺陷，要解决的问题如下：
1.不用再专门拍摄两个角度影视画面的3D影视，戴上该3D眼镜看2D画面的电影电视，通过解决2D视频同一组平行光线的同一个视频图像直接进入双眼产生立体视觉感的相互“干扰”而看不到3D立体影像的问题，能够看到3D立体影像；
2.克服在中国专利CN104246579A中反光镜片不能透光分光和移光而直接看视频以及立体视觉感的效果不足的缺陷；
3.克服现在3D影视角度拍摄视频的不同角度进入左右眼所产生视觉疲劳感的缺陷。
【解决问题所采用的技术手段】
如说明书附图1所示，对照上述1)、2)所表述的两个角度2D影像和 2个不同画面2D影像的3D眼镜技术特征和PCT公布(WO/2018/152654)的眼镜分解2D视频为等量的不同的A1和A2视频的技术特征，两者科学实质相同，一个是两个拍摄空间形成两个A1和A2显示空间，另一个是一个拍摄空间形成两个A1和A2显示空间，A1和A2进入人左右眼视觉空间，产生了物理学意义上的人体工学的视觉“4维空间”，前者产生不同角度图像的视距差，后者产生不同光线和分解2D视频为左右不同画面的视距差。本发明是采用2、10和3、11光学镜片的以棱镜(曲面透镜)为代表两枚以上组合镜片和左右眼镜镜框交替通透光栅技术手段，分解2D视频光线为A为两个不同的光线A1和A2，是一种光学镜片和光删的组合分解2D视频为3D视频的眼镜的制作方法，包括现有的光学镜片和光栅的组合，其特征在于：光学镜片组合，使得入射光线在组合镜片内反复发生折射和反射，确定射出光学镜片与射入光学镜片，使得射出光线方向与射入光线为相同的平行光线，出射光线与射入光线发生了平行位移，由此构成组合分光镜片；进入左右两组合分光镜片的平行光，发生左右两个光学镜片组对应界面点上的互为反向的折射和反射，同时可加入左右两个交替通透的光栅，实现分解A光为A1光和A2光，实现视距差立体视觉感。其中组合棱镜透光镜片分光式立体眼镜为表的主要技术特征为：
1)利用三棱镜为代表的光学镜片，进入光线在镜界面发生不同的折射反射，使得入射光和出射光成角度，改变了光路，又利用两个或两个以上以三棱镜为代表的光学镜片，组合成一个三棱镜(或光学镜片)组合体，这个三棱镜(或光学镜片)组合体，底面外形是一个正方形或平行四边形的进光光学镜片和出光光学镜片互为反向的对称组合，这样这个三棱镜组合镜片组的射进光镜面和射出光镜面是平行的，依据光路的可逆性原理，不管底面为正方形或平行四边形棱镜组合体内部的棱镜之间角度关系怎样，三棱镜片(光学镜片)组合镜片都 相当一枚“平光镜片”；
2)用两枚1)所述的“平光镜片”作为立体眼镜的左右眼镜框的左右眼镜片，左右两枚组合平光镜片内部镜面互为反向角度，并且两平光镜片前后镜面随同左右镜框一起互成角度150～90度的倒“V”字形，使得进入左右镜面的2D视频光线A入射角不同，由于光线组合镜内部的反射和折射都是互为相反的，A光线的在左右组合镜内部被多次互为反向地反射和折射而过滤掉了，后端镜面出来的是左右眼镜框内光学镜片组合分解了A光线为A1和A2光线；
3)上述1)、2)所述的光学镜片，代表性的有附图2所示的2、10和3、11直角三棱镜透光镜片，镜片的长直角边面和斜面的夹角度越大的三棱镜镜片组合成的平光镜片也越厚，依据2)所述做成眼镜时，厚端镜面相对前端镜面获得了更大的位移，使得进入左右眼的光线也获得来更大的入射光位移差，增强了视距差感，然尔，这种大夹角度的组合平光镜片太厚会增加眼镜的重量，所以，采用上述夹角度小的厚度小的三棱镜镜片，两镜片内面间隔出距离，间隔距离是间隔面最长尺寸的1/6为宜，使的小夹角度的组合“平光镜片”的厚度等同大夹角度的组合平光镜片的厚度，两者得分光移光效果及乎相同，后者重量减轻；
4)盖括1)、2)、3)的综合技术手段所代表的技术特征，得出眼镜左右镜片组合是两枚以上光学镜片，有棱镜或曲面透镜，因为镜框里前后光学镜片是对称反向组合，左右眼镜组合也互为反向，使得左右组合镜片所具有的技术特征为；2D视频入射光线以最大的互为相反的相同入射角射入左右组合镜的左右前镜片对应的平面或曲面上，并且使得射入光线同各自的组合镜后镜面射出的对应光线在一个平行方向上，因为2D视频的A光线射入两前端镜面光线的入射角互为相反最大，入射光线在左右组合镜片里使之对应的光线的折射和反射也互为相反，光线经过左右组合镜片内反复不同方相的折射反射，把2D视频的光线A 分解成了A1和A2两个不同的光线，同时入射光线经多次改变光路使得出射光线对入射光线产生位移，使得出镜面出来左右两个产生了互为反向小于厚度d的位移的人眼成像，增加了分解A为A1、A2的效果。使用曲面透镜的组合分解A位A1、A2，也是通过应用左右曲面镜片组合的对应曲面镜面上互为反向的折射和反射的技术手段来实现的。
5)如说明书附图1所示，利用4左光栅、5右光栅的交替通透光删技术，把2D视频空间交替地时空地分解为2个等量的不同的2D视频空间，进入左右眼的4维视觉空间，依据人体工学的自然属性，增加了立体视觉感。
对照上述1)、2)所表述的两个角度2D影像和2个不同画面2D影像的3D眼镜技术特征，是一种利用光学镜片和光删组合分解2D视频为3D视频的方法制作的光学镜片和光删的组合分解2D视频为3D视频的立体眼镜，如说明书附图1所示，眼镜外型和内部构造组成：包括1眼镜机壳、6左眼镜框、7右眼镜框，在6左眼镜框和7右眼镜框内，装配两组光学镜片，2左前光学镜片、左后光学镜片和3右前光学镜片、11右后光学镜片，在眼镜框内的两组光学镜片之间装配左右两个交替通透光栅，4左交替通透 光栅和5右交替通透光栅。

是一种光学镜片和光删组合分解2D视频为3D视频的立体眼镜，其附图2所示的叠合面与屏幕平面夹角￥，斜边角度30度三棱镜的叠合面与屏幕平面夹角￥，对应左右眼镜最大视角宽度，以小于70度的最大夹角￥1和￥2装配于左右眼镜框中，获得左右两镜片组合最大分光效果；通过反向安装两枚三棱镜，使得物镜光线两次相互反方向的改变光路，使得视觉图像光路没有发生改变，看物镜效果同一平面透镜，但由于来自2D显示屏幕平面光进入两组镜片的入射角不同，通过眼镜左右三棱镜片组合的折射反射作用，10左后三棱镜片、11右后三棱镜片出来的是同视频的不同角度的光线，分解入射光线为左右眼镜不同的光线，相当于产生了两眼视角不同的的视距差。
是一种光学镜片和光删组合分解2D视频为3D视频的立体眼镜，装配左右两个交替通透遮挡镜片，包括分时快门式液晶镜片：4左分时开关式液晶镜片和5右分时开关式液晶镜片。

【技术方案的效果】
2D视频出来的各个方向上平行光线是立体视觉光线，两眼直接看屏幕时，两眼相对平行光线的对称性和视频图像的相同性，干扰了两眼对2D视频的立体视觉感的生成。本眼镜左右眼镜框里的两组前后反向叠合的以三棱镜透光镜片为代表的光学镜片，使得射入左右镜片组的光线，通过三棱镜片(光学镜片)组合对光线反射、折射的多次作用和三棱镜镜片组合成的两个呈八字定位的组合平光镜镜片，分解和位移了2D视频的同方向光线为两个不同角度方向光线和两个不同位移的2D视频画面，不同角度光线的不同位置画面分别进入左右眼，解决了平行光线的相同2D视频对双眼立体视觉感的“干扰”而使其消失的问题，人眼感受到的是左右眼不同光线和位移到眼睛不同感光位置的这两个视 距差效果，实现了戴上眼镜直接看2D视频，获得3D立体视觉效果。
实际立体效果的检测。单眼看2D视频，能够看到立体视频是现在3D电影的基本技术原理，检测了本发明眼镜的立体感效果是：先单眼看2D视频，看到了单眼的立体视频，再戴上眼镜看2D视频，看到的是比单眼看到的更好的立体视频。
发明立体眼镜的立体视觉感效果与现在影院式3D眼镜的视觉效果的比较：
1)单眼立体感效果：戴各自眼镜单眼看视频的立体视觉感，发明立体眼镜优于3D眼镜；
2)双眼立体感效果：发明立体眼镜有纵深立体视觉感，没有角度立体视觉感；3D眼镜有角度立体视觉感，但没有纵深立体视觉感。所以，发明立体眼镜的在全景画面立体视觉感优于3D眼镜，是两眼看到的没有视觉角度锐度的立体视觉感。

具体实施方式
【实施方式】
附图1所示的是依据【0008】所述立体眼镜技术特征所设计的立体眼镜的外型和内部元件、构造、形状组成和位置关系，眼镜组成为：1眼镜机壳、6左眼镜框、7右眼镜框，左右眼镜框里装配有(直角或等边)三棱镜片：2左前三棱镜片、3右前三棱镜片、4左后三棱镜片、5右后三棱镜片的两组镜片，相当于对2D画面成外夹角角度的两个拍摄镜头，这个夹角是眼镜前端左右两前镜面夹角￥，￥取150～90度为宜；装配如附图1所示，在1眼镜机壳的6左眼镜框和7右眼镜框前后，各相嵌有两枚图1的右眼睛框三棱镜片前后装配位置1.的虚方框1.和左眼睛框三棱镜片前后装配位置2.的虚方框2.的所示前后两互为反向装配的直角三棱镜片2、4和、3、5，通过反向安装左右前两枚和后两 枚三棱镜镜片，使得2D视频光线以互为反向的入射角进入左右眼镜框的前镜面，进入光线通过后续的3个介面互为反方向地折射和反射改变光路，因组合前镜面和后镜面的平行对称，视觉图像光路方向没有发生改变，看物镜效果同一平面透镜，但由于来自2D显示屏幕平面光进入两组镜片的入射角不同，通过眼镜左右三棱镜片组合的多次反复折射反射作用，4左后三棱镜片、5右后三棱镜片出来的是同视频的不同角度的光线，并且光线发生了位移，分解入射光线为左右眼镜不同的光线，两眼的感光点也发生了位移差，相当于产生了两眼不同的角度光线差和位移图像感光差，这两个视距差合成为立体视觉感。
如附图1所示，在眼镜机壳1)左右眼镜框6、7里前后端安装各两枚直角三棱镜片2、4和3、5，选用角度60度直角三棱镜片，两斜面向内对向装配成底面长方形的组合“平光镜”，平光镜前入射面的入射角在保证视角范围，尽可能大角度安装，增加反射角度，增加反射量，进入左右眼镜框镜面折射光线和反射为角度不同的光线，使得左右两后三棱镜片10、11出来更多不同角度光线，两组光线视觉差就更大，获得了更强的立体视觉感；
【实施例】
附图2是立体眼镜的装配结构图，所示眼镜外壳1)的外形是依据一种具有通常左右眼镜框6、7的眼镜，眼镜左右眼镜框6、7内所装配有两枚以上光学镜片，这里装配有前(直角)三棱镜片2、3和后(直角)三棱镜片4、5，前后两8～15度直角三棱镜斜角面按附图2的虚方框2所示图.对向间距装配，形成底面为长方形(或平行四边形)的组合透光棱镜，内部对向面有间隔距离，是为了增加长方形(或平行四边形)棱镜镜片的“厚度”，以此增大出镜画面位移；在组合镜片厚度相同，是通过减小直角三棱镜镜片的厚度，增加前后镜片间隔，获得的，如说明书附图索示在眼镜机壳1左右眼镜框6、7里前后端棱镜 斜面对向间隔4～mm安装上面2枚镜(直角)三棱镜片，眼镜前左右两镜片对称同向对2D屏幕面成反向角度装配，眼镜后左右两直角三棱镜眼镜片的斜面与前左右两直角三棱镜片的斜面的平行面与屏幕面的夹角也使在确保获得交宽视野角度取光效果的条件下最大化，使入射光线呈不同反射、折射来进行分光，并且眼镜能有较宽视野；前后两叠合直角三棱镜片组的如附图1.的两个装配位置2的虚方框图内镜片组所示的进光面、叠合面对2D视频图像平面夹角￥越大(叠合面与2D屏幕面的夹角小于45度)，分光效果即光线视距差效果越好，同时互为反向内斜的左右眼镜框6、7，使得2D视频通过眼镜镜片时产生反向图像位移。
