在步骤S101中，确定拍摄设备的取景信息。
在一实施例中，可以通过拍摄设备的取景器来获取拍摄设备当前的取景信息。在一实施例中，取景信息可以通过无线传输或者有线传输的方式传输至显示设备，无线方式例如WIFI、蓝牙等，有线方式例如USB线等等，本公开对拍摄设备的取景信息的具体方式不做限制。
在步骤S102中，将取景信息显示在显示设备上。
在一实施例中，可以将取景信息以平行光束的方式显示在显示设备上；在另一实施例中，还可以将取景信息以取景框的方式显示在显示设备上。
下面结合图1B对图1A所示实施例进行示例性说明，立方体10设置在空间一位置处，拍摄设备11与用户均位于立方体10的A侧面，当拍摄设备11需要对立方体10进行拍摄时，如果拍摄设备11当前处于一位置较高处，此时用户并不能直接从拍摄设备11的显示屏上观看拍摄设备11的取景信息，在此情形下，通过本公开的方法将拍摄设备11当前的取景信息显示在显示设备12上，从而可以使用户在显示设备12上观看拍摄设备11当前的取景画面。
本实施例中，通过将拍摄设备的取景信息显示在显示设备上，可以使用户通过显示设备直接观看到拍摄设备的取景范围，实现了拍摄设备与取景显示的分离，对用户而言，简化了调整数码相机的取景范围的操作。
在一实施例中，将取景信息显示在显示设备上，可包括：
将取景信息转换为平行光束，平行光束的边界由取景信息来确定；
将平行光束投射到显示设备上。
在一实施例中，显示设备可以为智能眼镜，将取景信息显示在显示设备上，可包括：
确定取景信息对应的取景画面；
确定取景画面与智能眼镜的摄像装置所采集的图像画面之间的重复画面的百分比；
根据重复画面的百分比将取景信息显示在智能眼镜的镜片上。
在一实施例中，根据重复画面的百分比将取景信息显示在智能眼镜的镜片上，可包括：
如果重复画面的百分比大于第一预设阈值，将取景信息以完整取景框的方式显示在智能眼镜的镜片上；
如果重复画面的百分比小于第一预设阈值并且大于第二预设阈值，将取景信息以部分取景框的方式显示在镜片上。
在一实施例中，方法还可包括：
如果重复画面的百分比小于第二预设阈值，在镜片上显示用于引导用户调整视野方向的提示信息。
在一实施例中，显示设备可以为智能眼镜，将取景信息显示在显示设备上，可包括：
确定取景信息对应的取景画面；
确定取景画面的主体物与智能眼镜的摄像装置所采集的图像画面中的主体物之间的相似值；
根据相似值将取景信息显示在智能眼镜的镜片上。
在一实施例中，根据相似值确定将取景信息显示在智能眼镜的镜片上，可包括：
如果相似值大于第三预设阈值，将取景信息以完整取景框的方式显示在智能眼镜的镜片上；
如果相似值小于第三预设阈值并且大于第四预设阈值，将取景信息以部分取景框的方式显示在镜片上。
在一实施例中，方法还可包括：
如果相似值小于第四预设阈值，在镜片上显示用于引导用户调整视野方向的提示信息。
具体如何显示拍摄设备的取景信息的，请参考后续实施例。
至此，本公开实施例提供的上述方法，可以实现拍摄设备与取景显示的分离，对用户而言，简化了调整数码相机的取景范围的操作。
图2是根据一示例性实施例一示出的显示取景信息的方法的流程图，本实施例以显示设备为玻璃眼镜为例进行示例性说明，如图2所述，包括如下步骤：
在步骤S201中，确定拍摄设备的取景信息。
步骤S201的描述请参见上述步骤S101的描述，在此不再详述。
在步骤S202中，将取景信息转换为平行光束，平行光束的边界由取景信息来确定。
在一实施例中，可以才将电光转换的装置将取景信息转换为平行光束，例如，激光器，投影仪等。
在步骤S203中，将平行光束投射到玻璃眼镜上。
在一实施例中，可以通过在玻璃眼镜上设置微型投影装置，通过微型投影装置将拍摄设备的取景信息投射到玻璃眼镜的镜片上，从而使镜片能够达到透视的效果。
本实施例中，通过将拍摄设备的取景信息以平行光束的方式投射到玻璃眼睛上，在实现了拍摄设备与取景显示的分离的基础上；此外，由于近视将取景信息的边界投射到了玻璃眼镜上，用户既能够通过玻璃眼镜观看到拍摄设备当前的取景范围的同时，还能够通过玻璃眼镜观看到其眼前的真实场景，因此不会对用户的实际视野产生影响。
本领域技术人员可以理解的是，本公开上述实施例还可以通过将取景信息转换为平行光束，将平行光束通过投影仪投影到显示设备上。
图3A是本公开实施例所适用的智能眼镜与拍摄设备形成的系统图，图3B是本公开实施例示出的取景信息对应的取景画面的示意图，图3C是本公开实施例示出的智能眼镜所拍摄的图像画面的示意图之一，图3D是本公开实施例示出的智能眼镜所拍摄的图像画面的示意图之二，图3E是本公开实施例示出的智能眼镜所拍摄的图像画面的示意图之三；如图3A所示，智能眼镜31与拍摄设备11可以通过WIFI或者红外等无线方式进行通信，由此，拍摄设备11可以将其取景信息发送给智能眼镜31，其中，拍摄设备11可以通过设置在拍摄设备11上的取景器来确定智能设备32的镜头的取景信息，并将取景器所确定的取景信息发送给智能眼镜31，智能眼镜31将拍摄设备11的取景信息以取景框的方式显示在其镜片32上。在一实施例中，拍摄设备11可以为数码相机、运动相机、单反相机等能够采集数字图像的设备。
如图3B所示，为拍摄设备11当前的取景画面321，拍摄设备11的取景器通过该取景画面可以确定其取景信息。图3C所示为用户在佩戴智能眼镜31的一个角度智能眼镜31上的摄像装置所采集到的图像画面311，图3D所示为用户在佩戴智能眼镜31的另一个角度智能眼镜31上的摄像装置所采集到的图像画面312，图3E所示为用户在佩戴智能眼镜31的再一个角度智能眼镜31上的摄像装置所采集到的图像画面313。
例如，在一个示例性场景中，如图3B和图3C所示，拍摄设备11当前的取景画面321和智能眼镜31当前所拍摄的图像画面311中均出现了杯子，并且杯子在各自的画面中以大体相同的角度出现，在此情形下，可以确定取景画面与用户的视野方向大体一致，此时可以在智能眼镜31的镜片32上以取景框30的方式显示拍摄设备11的取景信息，用户在佩戴该智能眼镜31后，可以通过取景框30获知拍摄设备11当前的取景范围；在另一个示例性场景中，如图3D所示，用户佩戴智能眼镜31时从另一个角 度通过智能眼镜31的摄像装置采集到的图像画面312，从拍摄设备11的取景321和图像画面312的画面内容上来看，图像画面312中的杯子已经有一部分超出了智能眼镜31的视场范围，说明智能眼镜31与拍摄设备11当前的取景方向存在偏差，可以在镜片32上以部分取景框的方式显示拍摄设备11的取景画面，从而可以提醒用户在可视方向进行小幅度的调整，当检测到取景画面与用户的视野方向大体一致后，再将取景信息以取景框30的方式显示在镜片32上；在再一个示例性场景中，如图3E所示，用户佩戴智能眼镜31时从再一个角度通过智能眼镜31的摄像装置采集到的图像画面313，从拍摄设备11的取景画面321和图像画面313的画面内容上来看，图像画面313中的杯子基本上超出了用户当前的视场范围，说明智能眼镜31与拍摄设备11当前的取景方向存在较大偏差，此时可以在镜片32上显示用于引导用户调整视野方向的提示信息，以此引导用户调整其视野方向，直至检测到取景信息与用户的视野方向大体一致后，再将取景信息以取景框30的方式显示在镜片32上。
对于不能直接通过拍摄设备的取景器查看拍摄设备的视场范围的场合(例如，拍摄设备为运动相机，用户将运动相机固定在用户的头顶上方或沿着地面拍摄)，本实施例通过将拍摄设备的取景信息显示在显示设备上，可以使用户通过显示设备直接观看到拍摄设备的取景范围，实现了拍摄设备与取景显示的分离，对用户而言，简化了调整数码相机的取景范围的操作。如果显示设备为智能眼镜，由于智能眼镜的镜片上没有呈现拍摄设备当前所采集的图像，因此不会对用户的实际视野产生影响，从而能够使用户通过智能眼镜观看到拍摄设备当前的拍摄范围的同时，还能够观看到其眼前的真实场景，提高了用户使用智能眼镜的体验。
图4是根据一示例性实施例二示出的显示取景信息的方法的流程图；本实施例利用本公开实施例提供的上述方法，以根据取景信息对应的取景画面与智能眼镜的摄像装置所采集的图像画面之间的重复画面的百分比将取景信息显示在智能眼镜的镜片上为例并结合上述图3A至图3E进行示例性说明，如图4所示，包括如下步骤：
在步骤S401中，确定拍摄设备的取景信息。
步骤S401的描述可以参见上述步骤S101的描述，在此不再详述。
在步骤S402中，确定取景信息对应的取景画面。
在一实施例中，取景画面同样可以通过与上述步骤S401的方式传输至智能眼镜。
在步骤S403中，确定取景画面与智能眼镜的摄像装置所采集的图像画面之间的重复画面的百分比。
在一实施例中，可以通过对取景信息对应的取景画面与智能眼镜的摄像装置采集的图像画面中的灰度信息的对应关系进行相似性和/或一致性的分析，从而确定二者之 间具有重复画面的百分比，例如，可以将取景画面作为基准，确定智能眼镜的摄像装置采集的图像画面与拍摄设备采集的图像画面中的画面重复的范围，例如，将智能眼镜的摄像装置采集的图像画面分辨率为640×480，确定智能眼镜的摄像装置采集的图像画面与拍摄设备采集的图像画面中的画面重复的范围的像素点的个数为320×120，由此可以则二者影像目标的方法重复画面的百分比为(320×150)/(640×480)＝0.156。
在步骤S404中，将重复画面的百分比与第一预设阈值和第二预设阈值进行比较，通过比较结果确定将取景信息显示在智能眼镜的镜片上，例如，如果重复画面的百分比大于第一预设阈值，执行步骤S305，如果重复画面的百分比小于第一预设阈值并且大于第二预设阈值，执行步骤S306，如果重复画面的百分比小于第二预设阈值，执行步骤S307。
在一实施例中，第一预设阈值与第二预设阈值可以根据拍摄设备和智能眼镜的摄像装置的分辨率来确定，由此可以确保重复画面的百分比的计算精确度。
在步骤S405中，如果重复画面的百分比大于第一预设阈值，将取景信息以完整取景框的方式显示在智能眼镜的镜片上。
如图3C所示，智能眼镜31当前所拍摄的图像画面311中出现了杯子，由此在确定杯子所在场景在取景画面和图像画面中的重复画面的百分比大于第一预设阈值时，表明杯子在各自的画面中以大体相同的角度出现，在此情形下，可以确定取景画面与图像画面一致，此时可以在智能眼镜31的镜片32上显示以完整取景框30的方式显示取景信息，用户在佩戴该智能眼镜31后，可以通过完整取景框30获知拍摄设备11当前的取景范围。在一实施例中，可以将完整取景框30以彩色框的方式显示在镜片32上，例如，取景信息30在取景画面与图像画面大体一致时以绿色框的形式呈现在镜片32上。
在步骤S406中，如果重复画面的百分比小于第一预设阈值并且大于第二预设阈值，将取景信息以部分取景框的方式显示在镜片上。
如图3D所示，用户佩戴智能眼镜31时从另一个角度通过智能眼镜31的摄像装置采集到的图像画面312，从拍摄设备11的取景画面321和图像画面312的画面内容上来看，通过图像检测技术可以确定拍摄设备11所拍摄的图像321和图像画面312中的重复画面的百分比将会变小，例如重复画面的百分比小于第一预设阈值并且大于第二预设阈值时，表明智能眼镜31与拍摄设备11当前的取景方向存在偏差，可以在镜片32上显示部分取景信息30，并以红色框的形式呈现在镜片32上，以此提供用户进行小幅度的可视方向调整，当检测到取景信息与第二取景信息大体一致后，再将取景信息30显示在镜片32上。
在步骤S407中，如果重复画面的百分比小于所述第二预设阈值，在镜片上显示用于引导用户调整视野方向的提示信息。
如图3E所示，用户佩戴智能眼镜31时从再一个角度通过智能眼镜31的摄像装置采集到的图像画面313，从拍摄设备11所拍摄的图像画面321和图像画面313的画面内容上来看，通过图像检测技术可以确定拍摄设备11所拍摄的图像321和图像画面312中的重复画面的百分比将会变小，例如小于第二预设阈值时，说明图像画面313中的杯子基本上超出了智能眼镜31的视场范围，智能眼镜31与拍摄设备11当前的取景方向存在较大偏差，此时可以在镜片32上对用户需要移动的方向进行提示，以此引导用户调整其视野方向，直至检测到取景信息与第二取景信息大体一致后，再将取景信息30显示在镜片32上，例如，通过箭头提示用户调整其当前的视场范围，从而使用户能够获知拍摄设备11当前的视场范围。
对于不能直接通过拍摄设备的取景器查看拍摄设备的视场范围的场合(例如，拍摄设备为运动相机，用户将运动相机固定在用户的头顶上方或沿着地面拍摄)，本实施例根据重复画面的百分比确定拍摄设备的取景信息在智能眼镜的镜片上的显示方式，不会对用户的实际视野产生影响，从而能够使用户通过智能眼镜观看到拍摄设备当前的拍摄范围的同时，还能够观看到其面前的真实场景，提高了用户使用智能眼镜的体验。
图5是根据一示例性实施例三示出的显示取景信息的方法的流程；本实施例利用本公开实施例提供的上述方法，以如何根据取景信息对应的取景画面中的主体物与智能眼镜的摄像装置所采集的图像画面中的主体物之间的相似值来将拍摄设备的取景信息显示在智能眼镜的镜片上为例并结合上述图3A至图3E进行示例性说明，如图5所示，包括如下步骤：
在步骤S501中，确定拍摄设备的取景信息。
步骤S501的描述可以参见上述步骤S101的描述，在此不再详述。
在步骤S502中，确定取景信息对应的取景画面。
步骤S502的描述可以参见上述步骤S402的描述，在此不再详述。
在步骤S503中，确定取景画面的主体物与智能眼镜的摄像装置所采集的图像画面中的主体物之间的相似值。
在一实施例中，可以通过对拍摄设备采集的取景画面与智能眼镜的摄像装置采集的图像画面中的画面内容(本公开实施例中的主体物)的对应关系进行相似性分析，从而确定二者之间的相似值。
在步骤S504中，将相似值与第三预设阈值和第四预设阈值进行比较，通过比较结 果确定将取景信息显示在智能眼镜的镜片上，例如，如果相似值大于第三预设阈值，执行步骤S505，如果相似值小于第三预设阈值并且大于第四预设阈值，执行步骤S506，如果相似值小于第四预设阈值，执行步骤S507。
在一实施例中，第三预设阈值与第四预设阈值可以根据拍摄设备和智能眼镜的摄像装置的分辨率来确定，由此可以确保重复画面的百分比的计算精确度。
在步骤S505中，如果相似值大于第三预设阈值，将取景信息以完整取景框的方式显示在智能眼镜的镜片上。
如图3C所示，如图3B和图3C所示，拍摄设备11当前的取景画面321和智能眼镜31当前所拍摄的图像湖面311中均出现了杯子，如果通过图像检测技术确定二者之间的相似值大于第三预设阈值，确定并且杯子在各自的画面中以大体相同的角度出现，在此情形下，可以确定取景湖面321与图像画面311的取景方向大体一致，此时可以在智能眼镜11的镜片32上以取景框30的方式显示拍摄设备11的取景信息，用户在佩戴该智能眼镜31后，可以通过取景框30获知拍摄设备11当前的取景范围。在一实施例中，可以将取景框30以彩色框的方式显示在镜片33上，例如，在取景画面321与图像画面311的取景方向大体一致时取景框30以绿色框的形式呈现在镜片32上。
在步骤S506中，如果相似值小于第三预设阈值并且大于第四预设阈值，将取景信息以部分取景框的方式显示在镜片上。
如图3D所示，用户佩戴智能眼镜11时从另一个角度通过智能眼镜11的摄像装置采集到的图像画面312，从拍摄设备11所拍摄的取景画面321和图像画面312的画面内容上来看，通过图像检测技术可以确定拍摄设备11所拍摄的取景画面321和图像画面312中的杯子的相似值将会变小，例如，杯子的相似值小于第三预设阈值并且大于第四预设阈值时，表明智能眼镜31与拍摄设备11当前的取景方向存在偏差，可以在镜片32上显示部分取景框的方式显示取景信息，并以红色框的形式呈现在镜片32上，以此提供用户进行小幅度的可视方向调整，当检测到取景信息与第二取景信息大体一致后，再将取景信息以完整取景框的方式显示在镜片32上。
在步骤S507中，如果相似值小于所述第四预设阈值，在镜片上显示用于引导用户调整视野方向的提示信息。
如图3E所示，用户佩戴智能眼镜11时从再一个角度通过智能眼镜11的摄像装置采集到的图像画面313，从拍摄设备11所拍摄的取景画面321和图像画面313的画面内容上来看，通过图像检测技术可以确定拍摄设备11所拍摄的取景画面321和图像画面312中的杯子的相似值将会变小，例如小于第四预设阈值时，说明图像画面313中的杯子基本上超出了智能眼镜11的视场范围，智能眼镜11与拍摄设备11当前的取景 方向存在较大偏差，此时可以在镜片32上对用户需要移动的方向进行提示，以此引导用户调整其视野方向，直至检测到取景信息与第二取景信息大体一致后，再将取景信息以完整取景框的方式显示在镜片32上，例如，通过箭头提示用户调整其当前的视场范围，从而使用户能够获知拍摄设备11当前的视场范围。
对于不能直接通过拍摄设备的取景器查看拍摄设备的视场范围的场合(例如，拍摄设备为运动相机，用户将运动相机固定在用户的头顶上方或沿着地面拍摄)，本实施例根据相似值确定拍摄设备的取景信息在智能眼镜的镜片上的显示方式，不会对用户的实际视野产生影响，从而能够使用户通过智能眼镜观看到拍摄设备当前的拍摄范围的同时，还能够观看到其面前的真实场景，提高了用户使用智能眼镜的体验。
本领域技术人员可以理解的是，上述仅以重复画面的百分比和主体物进行示例性说明，本公开还可以通过取景画面和图像画面中的图像特征、图像画面中的纹理特征等信息来确定二者之间在视场范围的一致程度，上述重复画面的百分比和主体物的示例性说明并不能形成对本公开的限制。
