 背景技术
眼球追踪技术可以采用光学记录法实现。光学记录法的原理是，利用红外相机记录被测试者的眼睛运动情况，即获取能够反映眼睛运动的眼部图像，从获取到的眼部图像中提取眼部特征，以建立视线的估计模型。其中，眼部特征可以包括：瞳孔位置、瞳孔形状、虹膜位置、虹膜形状、眼皮位置、眼角位置、光斑位置(或者普尔钦斑)等。光学记录法包括瞳孔-角膜反射法。瞳孔-角膜反射法的原理是，近红外光源照向眼睛，由红外相机对眼部进行拍摄，同时拍摄到光源在角膜上的反射点即光斑，由此获取到带有光斑的眼部图像。
目前应用在虚拟现实眼镜和增强现实眼镜上的眼球追踪识别设备，由采集图像部分与普尔钦斑映射部分组成。其中，采集图像部分，主要通过采集眼球2的反射光斑来对眼球的位置进行追踪，通常的应用场景中，主要使用以下方案进行采集：
(1)如图1所示，图像采集器3直接透过目镜1进行图像采集。
(2)如图2所示，利用内部其他镜片4的表面反射，再透过目镜1，图像采集器3进行图像采集。
(3)如图3所示，利用内部增加反射镜4，再透过目镜1，图像采集器3进行图像采集。
(4)如图4所示，光路先入射目镜1内部，在目镜1的外表面进行反射，图像采集器3进行图像采集。
在以上采集方案中，增加镜片会导致设备整体的体积变大，并且眼球2的反射光线容易在目镜1的表面，或者增加的镜片表面发生全反射，使得图像采集器3无法采集到眼球2的反射光线，进而导致无法对眼球进行追踪。

图1至图4是相关技术中的待成像光线的光路图，其中，图1中所示方案，直接采集图像受光路体积影响较大，且透过镜片时，容易发生全反射而无法采集；图2中所示方案采用内部其他镜片，反射效果受限制，无法进行针对性优化，也容易发生全反射；图3中所示方案，在内部增加反射镜空间受限严重，很多场景无法实现；图4中所示方案利用目镜另一个面反射，受限于反射面必须为凸面，凹面会全反射无法采集。
针对上述问题，本公开提出了一种眼球追踪光学装置、***和虚拟现实设备，其中，眼球追踪光学装置，包括：光源组件、透镜组件、反射组件和图像采集组件；其透镜组件包括远离眼球依次设置的第一透镜部和第二透镜部，第一透镜部远离眼球的一侧面具有凹面，第二透镜部近邻眼球的一侧面具有凸面，凹面与凸面贴合形成胶合面，胶合面设置有第一反射层，第一透镜部和第二透镜部形成透镜；反射组件位于透镜组件近邻图像采集组件的位置；光源组件设置为出射第一光线至眼球，第一反射层设置为反射第一光线的反射光线形成第一反射光线，反射组件设置为至少反射一次第一反射光线形成待成像光线；图像采集组件设置为采集待成像光线，以对眼球进行追踪。由此，通过将原透镜组件中的透镜设置为胶合透镜，并将胶合面设置第一反射层，进而对第一光线的反射光线可以反射形成第一反射光线，然后反射组件对第一反射光线至少反射一次形成待成像光线，入射至图像采集组件，从而改善了原先图像采集部分存在的第一光线的反射光线易被目镜或增加的镜片全反射，图像采集组件采集不到待成像光线的问题。
图5是本公开提出的眼球追踪光学装置的光路原理图。如图5所示，该眼球追踪光学装置100，包括：光源组件101、透镜组件102、反射组件103和图像采集组件104；其中，
透镜组件102包括远离眼球105依次设置的第一透镜部1021和第二透镜部1022，第一透镜部1021远离眼球105的一侧面具有凹面，第二透镜部1022近邻眼球105的一侧面具有凸面，凹面与凸面贴合形成胶合面，胶合面设置有第一反射层1023，第一透镜部1021和第二透镜部1022形成胶合透镜；
反射组件103位于透镜组件102近邻图像采集组件104的位置；
光源组件101设置为出射第一光线106至眼球105，第一反射层1023设置为反射第一光线106的反射光线107形成第一反射光线108，反射组件103设置为至少反射一次第一反射光线108形成待成像光线109；
图像采集组件104设置为采集待成像光线109，以对眼球105进行追踪。
需要说明的是，光源组件101可以布置在透镜组件102周围，图5所示的光源组件101仅为其中的一部分。光源组件101出射第一光线106至眼球105，在眼球105上形成光斑，眼球105对第一光线106反射形成反射光线107，反射光线107经过第一反射层1023的反射形成第一反射光线108，第一反射光线108经过反射组件103反射形成待成像光线109出射，并入射至图像采集组件104，图像采集组件104对待成像光线109进行成像，以对眼球105进行追踪。
其中，第一透镜部1021的凹面和第二透镜部1022的凸面贴合形成胶合面，贴合的材料可以为透明的光学胶，比如聚酰亚胺材料。第一透镜部1021和第二透镜部1022是同一透镜的不同组成部分，在第一透镜部1021和第二透镜部1022贴合后形成相关设备中的一片透镜(比如目镜)。另外，第一反射层1023可以反射光源组件101出射的波段的光线。第一反射层1023可以涂覆在第一透镜部1021的凹面上，和/或，第二透镜部1022的凸面上。另外，可以在眼球追踪光路方案设计阶段，对第一透镜部1021和第二透镜部1022的中间面型(胶合面的曲率)进行针对性优化，第一透镜部1021和第二透镜部1022的折射率相同(或不同，需要根据具体使用场景选择折射率)，可优化找出适合应用场景的反射面型(一般为凸面，凸起朝向眼睛一侧)。第一反射层1023不影响相关设备的可视画面的呈现。图像采集组件104可以为CMOS相机或者CCD相机，也就是说，图像采集组件104可以包括COMS或CCD感光芯片中的一种。至此，图像采集组件104在对眼部图像采集的同时，不影响原有光路***设计。进而，第一透镜部1021和第二透镜部1022的胶合，基于无需改变原有的光路设计，无需增加新的镜片，改变了待成像光线的光路走向，使得设备结构紧凑，并解决了相关技术中易发生全反射的问题。
反射组件103位于透镜组件102近邻图像采集组件104的位置，设置为对第一反射层1023反射形成的第一反射光线108进行再次反射，避免了第一反射光线108自透镜组件102近邻眼球105的一侧面出射，有利于图像采集组件104位于设备内部进行集成。
由此，反射组件103的设置便于图像采集组件104的位置摆放。
可选地，如图5所示，反射组件103包括：第二反射层1031，第二反射层1031贴合于第一透镜部1021近邻眼球105的一侧的部分表面上。
其中，第二反射层1031可以为反射光源组件101出射的波段的光线。可选地，第二反射层1031位于透镜组件102的非可视区域。
如图6所示，透镜组件102具有可视区域1025和非可视区域1024，可视区域1025设置为在用户使用设备时，进行画面的呈现显示，非可视区域1024为透镜组件102的闲置非显示边框区域。进而，可以将透镜组件102中的胶合透镜近邻图像采集组件104的部分(非可视区域1024)设置第二反射层1031，以达到将第一反射光线108反射形成待成像光线109自第一透镜部1021远离眼球的一侧面出射的目的，这样有利于图像采集组件104设置在设备整体内部，有利于设备整体的集成。解决了第一反射光线108沿胶合透镜近邻眼球的一侧面出射，最终使得图像采集组件104需要安装在设备外部，设备体积比较大的问题。
由此，第一反射层1023和第二反射层1031的设置使得在不增加新镜片的基础上，改变了原来第一反射光线108的光路设计，解决了第一光线106的反射光线107容易发生全反射，图像采集组件104无法采集到待成像光线的问题。
根据本公开的一个实施例，如图7至图9所示，反射组件103还包括：反射棱镜1032或反射平面镜1033或反射曲面镜1034中的一种，设置为调整自第二反射层1031反射形成的第二反射光线110的方向，形成待成像光线109。
可选地，反射棱镜1032或反射平面镜1033或反射曲面镜1034中的一种与第一透镜部1021固定贴合设置。其中，贴合可通过光学胶粘合实现。
如图7至图9所示，反射棱镜1032或反射平面镜1033或反射曲面镜1034的一侧设置有第三反射层，经第二反射层1031反射形成的第二反射光线110进入反射棱镜1032之后，经过第三反射层的再次反射形成待成像光线109，待成像光线109由图像采集组件104采集。从而，有利于图像采集组件104的位置的灵活设置。
根据本公开明的一个实施例，凹面或凸面的直径大于或等于透镜组件102的可视区域1025。由此，使得胶合面的边缘位于透镜组件102的非可视区域1024之中，以避免胶合边缘对可视区域1024中的可视画面造成影响。如图6中所示，可视区域1025与非可视区域1024的分界线可以作为胶合面的外轮廓边缘。
可选地，光源组件101为红外光源组件，第一反射层1023为红外反射层，反射组件103为红外反射组件。
在上述所有实施例中，光源组件101可以为红外光源组件，第一反射层1023可以为红外反射层，反射组件103中的第二反射层1031也可以为红外反射层，以及反射组件103中的反射棱镜1032或反射平面镜1033或反射曲面镜1034的一侧设置的第三反射层也可以为红外反射层，红外光源组件可以为多个红外LED灯排列在透镜组件102周围。图像采集组件104可以包括相应的红外成像***。
由此，针对图1至图4相关技术中所示的方案，在使用时都有相应的受限场景的问题，本公开提出的胶合方案可以改善其中问题，胶合方案将目镜拆分成两部分，拆分后的面型可以进行针对性优化，以适应不同的使用场景，自由选择角度的放大倍率。具体地，图1中的光路使用场景受限，在出瞳距离较近的***中，图像采集距离太短，无法满足大视野的需求。本公开提出的眼球追踪光学装置通过折叠光路，增加光路长度，从而规避了此问题。图2中受到原有***设计制约，原有的***的反射面无法进行优化，可能无法得到很好的采集效果。本公开提出的眼球追踪光学装置通过对胶合面进行优化很好的解决了这个问题。图3中内部增加反射镜需要至少2cm的空气间隙，很多设备无法满足此条件，本公开提出的眼球追踪光学装置不受此限制。图4中目镜的第二个面一般为凹面，容易发生严重的全反射，此时拍摄效果会急剧变差。本公开提出的眼球追踪光学装置的反射面可为凸面，从而规避了此问题。
图10是本公开提出眼球追踪光学***的方框示意图。如图10所示，该眼球追踪光学***200，包括：两个如本公开任一实施例的眼球追踪光学装置100，以及
左眼观看组件201，一个眼球追踪光学装置100安装在左眼观看组件201上；
右眼观看组件202，一个眼球追踪光学装置100安装在右眼观看组件202上；
左眼观看组件201和右眼观看组件202左右对称分布。
[根据细则91更正 21.07.2023]
图11是本公开提出的虚拟现实设备的方框示意图。如图11所示，该虚拟显示设备300包括本公开提出的眼球追踪光学***200。
综上所述，根据本公开提出的眼球追踪光学装置、***和虚拟现实设备，其中，眼球追踪光学装置，包括：光源组件、透镜组件、反射组件和图像采集组件；其透镜组件包括远离眼球依次设置的第一透镜部和第二透镜部，第一透镜部远离眼球的一侧面具有凹面，第二透镜部近邻眼球的一侧面具有凸面，凹面与凸面贴合形成胶合面，胶合面设置有第一反射层，第一透镜部和第二透镜部形成透镜；反射组件位于透镜组件近邻图像采集组件的位置；光源组件设置为出射第一光线至眼球，第一反射层设置为反射第一光线的反射光线形成第一反射光线，反射组件设置为至少反射一次第一反射光线形成待成像光线；图像采集组件设置为采集待成像光线，以对眼球进行追踪。由此，通过将原透镜组件中的透镜设置为胶合透镜，并将胶合面设置第一反射层，进而对第一光线的反射光线可以反射形成第一反射光线，然后反射组件对第一反射光线至少反射一次形成待成像光线，入射至图像采集组件，从而改善了原先图像采集部分存在的第一光线的反射光线易被目镜或增加的镜片全反射，图像采集组件采集不到待成像光线的问题。
