Description

一种三维内容的观看提示方法和装置 技术领域
本申请涉及三维立体显示技术领域，尤其涉及三维内容的观看提示方法和装置，可应用于云端智能机器人。
背景技术
3D(3Dimensional，三维)显示技术在中高端手机中越来越普及，越来越多的应用也采用3D的方式来呈现，如3D电影和3D地图等。随着云端智能机器人技术的发展，3D显示会越来越多地呈现，呈现质量也会越来越好。但是，在现阶段，一些用户第一次使用时很难观察到3D效果，其原因是当前最为广泛使用的手机3D显示方案是基于视差屏障技术。为了获得最好的观看效果，视差屏障技术要求用户的眼睛必须保持在视觉甜区位置。
如图1所示，左侧菱形为右眼的甜区，右侧菱形为左眼的甜区。对3D样本的观察效果测试表明，为保持用户的眼睛在视觉甜区位置，对成人来说，头部的角度自由度只有+/-3度，距离自由度在30厘米到50厘米之间，可见这是一个限制很大，若用户不能找到视觉甜区，则非常影响用户体验。
发明内容

在一个方面，本申请实施例提供了一种三维内容的观看提示方法，包括：

具体实施方式
为了使本申请的技术方案及优点更加清楚明白，以下结合附图对本申请的示例性实施例进行进一步详细的说明，显然，所描述的实施例仅是本申请的一部分实施例，而不是所有实施例的穷举。并且在不冲突的情况下，本说明书中的实施例及实施例中的特征可以互相结合。
为了提升用户体验，针对那些第一次使用手机3D显示或者对手机3D显示不太熟悉的用户，以及对3D显示视觉效果要求比较高的用户，我们基于视觉识别技术，为用户提供一种视觉的甜区指示方法，来帮助用户找到3D显示的最佳观看点。
本申请的关键之处在于利用智能手机或其他3D显示设备(如云端智能机器人的3D显示设备)的前摄像头来检测用户的瞳孔距离和位置，来判断瞳孔是否处于甜区位置，判断结果可以通过屏幕上的显示或者语音/声音的方式来反馈给用户。
图2示出了本申请实施例中的三维内容的观看提示方法，包括：
步骤101，根据用户的瞳孔距离确定该用户观看三维内容时与屏幕的合适距离；
步骤102，通过前置摄像头获取该用户的图像；
步骤103，根据该用户的图像确定该用户与该屏幕的实际距离；
步骤104，根据该实际距离是否符合该合适距离进行用户提示。
通过上述流程，可以帮助用户找到3D显示的最佳观看距离，帮助用户在观看时保持在视觉甜区，保障3D内容的观看效果。
进一步地，上述流程中实际距离是否符合该合适距离的判断方式可以为：
该合适距离为一个距离区间，该实际距离落入该区间则判断出该实际距离符合所述合适距离；或
该合适距离为一个距离值，该实际距离等于该合适距离则判断出所述实际距离符合该合适距离；或
该合适距离为一个距离值，该实际距离与所述合适距离的差值在设定阈值范围内则判断出该实际距离符合该合适距离。
上述不同的实际距离是否符合该合适距离的判断方式，为判断提供了多种实现方案。
进一步地，在该实际距离符合该合适距离后，根据该用户的图像中左右眼的像素坐标，确定左右眼在水平方向是否位于合适区域，并进行用户提示。
由于视觉甜区位于在水平方向上，位于屏幕的中间位置，因此，在提示用户合适的观看距离之后，用户可自行在该距离上根据视觉效果确定水平方向是否落入视觉甜区。但是，对于部分追求高质量3d效果的用户，也为了更好地服务用户，本发明实施例中，在确定了该实际距离符合该合适距离后，还可以对根据该用户的图像中左右眼的像素坐标，确定左右眼在水平方向是否位于合适区域，并进行用户提示，从而更加准确地帮助用户确定用户的瞳孔位于视觉甜区。
进一步地，获取该用户的图像后，还包括：识别用户两个瞳孔的位置，若判断出两个瞳孔的纵坐标不一致，则对用户进行提示。
对两个瞳孔的纵坐标不一致的情况进行提示，可以使得用户瞳孔中心的连线要和屏幕的x轴方向平行，通过提示对存在的角度进行矫正，使用户获得更好的观影效果。
为了便于本申请的实施，下面以实施例进行说明。
实施例一：
图3示出了本申请实施例一中的三维内容的观看提示方法，包括：
步骤201，确定用户瞳孔距离。
用户瞳孔距离可由用户设置，也可以采用默认值，或者根据用户的信息来确定。
具体来说，可以如下：
可设置用户瞳孔距离的默认值，默认值可根据需要设置。由于儿童的瞳孔距离通常为55毫米，女性成人的瞳孔距离通常为65毫米，男性成人的瞳孔距离通常为70毫米，因此，本实施例中的默认值设置为65毫米，在具体实现时可根据需要设置。
在存在默认值或不存在默认值的情况下，用户均可自行设置瞳孔距离。
若用户已知自己的瞳孔距离，则手动输入自己的瞳孔距离即可。
若用户不知道自己的瞳孔距离，则可以让用户提供自己的年龄和性别，通过查表的方式来计算瞳孔距离，表格可以如表1所示(不同国家和不同人种，表格中的数值可能会不同)。
表1
  儿童(毫米) 成人(毫米)
男 55 70
女 55 65
步骤202，根据用户的瞳孔距离确定该用户观看三维内容时与屏幕的合适距离。
一般3D显示技术都是基于默认的瞳孔距离6毫米来设计，这时最佳的观看距离是35厘米，视线和屏幕法线的角度自由度+/-3度。然而，每个人的瞳孔间距都是不一样的，如：儿童的瞳孔间距为55mm的话，那最佳观看距离为30cm，视线和屏幕法线的角度自由度为+/-3.5度。通过简单的线性公式可以计算出最佳观看距离，公式如下：
P＝30+(X-55)*(35-30)/(65-55)        公式(1)
其中，P为最佳观看距离，X为用户的瞳孔距离。
在具体实现时，可以将P直接作为该用户观看三维内容时与屏幕的合适距离，也可以根据P给出一个区间作为合适距离，例如以【P-10，P+1O】毫 米作为合适距离的距离区间。
步骤203，通过前置摄像头获取该用户的图像；
在本实施例中，前摄像头在打开3D显示模式时，会自动启动。本实施例需要双眼同时位于图片中，通过对拍摄的图片进行分析，可以判定出拍摄的人脸图片是否为有效图片。图4中左图为有效图片，右图为无效图片。
步骤204，根据该用户的图像确定该用户与该屏幕的实际距离；
步骤205，进行瞳孔水平方向校正；
在计算观看距离前，可以对观影角度进行校正，如图5所示，用户的瞳孔中心的连线要和屏幕的x轴方向不是平行，可以对存在的角度进行矫正。在最理想的场景中，在计算瞳孔间距离时，N1＝Nr，即瞳孔中心的连线要和屏幕的x轴方向平行。
具体来说，若判断出两个瞳孔的纵坐标不一致，则对用户进行提示。对用户进行提示可以通过图6中的“眼睛位置指示”用不同的颜色来提示用户。如：黑色代表瞳孔位置水平，白色代表瞳孔中心线和X轴有夹角。
然而，虽然进行瞳孔水平方向校正可以更好地通过U＝M1-Mr来计算用户在获取的图像中的瞳孔距离。但进行瞳孔水平方向校正并非必要步骤，只要识别出了两个瞳孔的位置，那么即可通过两个瞳孔的坐标计算用户在获取的图像中的瞳孔距离。
步骤206，根据该用户的图像确定该用户与该屏幕的实际距离。
本步骤中该用户与该屏幕的实际距离的计算方法为：
Figure PCTCN2016077315-appb-000001
其中，Y为用户与屏幕的实际距离，U为用户的图像中用户瞳孔的距离，V为前置摄像头拍摄照片的宽度，alpha为前置摄像头的拍摄视角，X为用户的瞳孔距离。上述各参数如图7所示，U、V还可以参考图4。
步骤207，根据该实际距离是否符合该合适距离进行用户提示。
该合适距离为一个距离区间，该实际距离落入该区间则判断出该实际距离符合所述合适距离，在本实施例中，若以【P-10，P+10】毫米作为合适距离的距离区间，则根据Y是否落入该区间来进行判断；或
该合适距离为一个距离值P，该实际距离等于该合适距离则判断出所述实际距离符合该合适距离；或
该合适距离为一个距离值P，该实际距离与所述合适距离的差值P-Y在设定阈值范围(如+/-10毫米)内则判断出该实际距离符合该合适距离。
此外，当Y值处于甜区的垂直区域内时，左右眼的像素坐标是已知的，通过左右眼的水平像素坐标值，可以判断出左右眼是否在水平方向上位于甜区内。
具体提示可如图8所示，通过在屏幕上进行是否位于甜区的提示，可提醒用户不断调整观看位置，通过眼睛位置指示，可以很容易判断自己的双眼是否位于最佳观看的甜区位置。
基于同一发明构思，本申请实施例中还提供了一种三维内容的观看提示装置，由于这些设备解决问题的原理与一种三维内容的观看提示方法相似，因此这些设备的实施可以参见方法的实施，重复之处不再赘述。
如图9所示，本申请实施例中三维内容的观看提示装置，包括：
合适距离确定模块901，用于根据用户的瞳孔距离确定该用户观看三维内容时与屏幕的合适距离；
前置摄像头902，用于获取该用户的图像；
实际距离确定模块903，用于根据该用户的图像确定该用户与该屏幕的实际距离；
提示模块904，用于根据该实际距离是否符合该合适距离进行用户提示。
提示模块904中实际距离是否符合所述合适距离的判断方式可以为：
该合适距离为一个距离区间，该实际距离落入该区间则判断出该实际距离符合所述合适距离；或
该合适距离为一个距离值，该实际距离等于该合适距离则判断出所述实际距离符合该合适距离；或
该合适距离为一个距离值，该实际距离与所述合适距离的差值在设定阈值范围内则判断出该实际距离符合该合适距离。
此外，提示模块904还可以用于在所述实际距离符合所述合适距离后，根据该用户的图像中左右眼的像素坐标，确定左右眼在水平方向是否位于合适区域，并进行用户提示。
该装置还可以包括水平调整模块905，如图10所示，用于在获取该用户的图像后，识别用户两个瞳孔的位置，若判断出两个瞳孔的纵坐标不一致，则对用户进行提示。
本申请实施例中的三维内容的观看提示装置可以是移动终端，也可以是云端智能机器人。

本申请是参照根据本申请实施例的方法、设备(系统)、和计算机程序产品的流程图和/或方框图来描述的。应理解可由计算机程序指令实现流程图和/或方框图中的每一流程和/或方框、以及流程图和/或方框图中的流程和/或方框的结合。可提供这些计算机程序指令到通用计算机、专用计算机、嵌入式处理机或其他可编程数据处理设备的处理器以产生一个机器，使得通过计算机或其他可编程数据处理设备的处理器执行的指令产生用于实现在流程图一个流程或多个流程和/或方框图一个方框或多个方框中指定的功能的装置。
这些计算机程序指令也可存储在能引导计算机或其他可编程数据处理设备以特定方式工作的计算机可读存储器中，使得存储在该计算机可读存储器 中的指令产生包括指令装置的制造品，该指令装置实现在流程图一个流程或多个流程和/或方框图一个方框或多个方框中指定的功能。
这些计算机程序指令也可装载到计算机或其他可编程数据处理设备上，使得在计算机或其他可编程设备上执行一系列操作步骤以产生计算机实现的处理，从而在计算机或其他可编程设备上执行的指令提供用于实现在流程图一个流程或多个流程和/或方框图一个方框或多个方框中指定的功能的步骤。
尽管已描述了本申请的优选实施例，但本领域内的技术人员一旦得知了基本创造性概念，则可对这些实施例作出另外的变更和修改。所以，所附权利要求意欲解释为包括优选实施例以及落入本申请范围的所有变更和修改。

Claims (10)

  3. 如权利要求1所述的方法，其特征在于，在所述实际距离符合所述合适距离后，根据所述用户的图像中左右眼的像素坐标，确定左右眼在水平方向是否位于合适区域，并进行用户提示。
  4. 如权利要求1所述的方法，其特征在于，获取所述用户的图像后，还包括：
    识别用户两个瞳孔的位置，若判断出两个瞳孔的纵坐标不一致，则对用户进行提示。
  5. 如权利要求1所述的方法，其特征在于，所述根据用户的瞳孔距离确定所述用户观看三维内容时与屏幕的合适距离的计算方法为：
    P＝30+(X-55)*(35-30)/(65-55)
    其中，P为所述合适距离，X为所述用户的瞳孔距离。
  6. 如权利要求1所述的方法，其特征在于，所述根据所述用户的图像确 定所述用户与所述屏幕的实际距离的计算方法为：
    Figure PCTCN2016077315-appb-100001
    其中，Y为所述用户与所述屏幕的实际距离，U为所述用户的图像中用户瞳孔的距离，V为所述前置摄像头拍摄照片的宽度，alpha为所述前置摄像头的拍摄视角，X为所述用户的瞳孔距离。
  7. 一种三维内容的观看提示装置，其特征在于，包括：
    合适距离确定模块，用于根据用户的瞳孔距离确定所述用户观看三维内容时与屏幕的合适距离；
    前置摄像头，用于获取所述用户的图像；
    实际距离确定模块，用于根据所述用户的图像确定所述用户与所述屏幕的实际距离；
    提示模块，用于根据所述实际距离是否符合所述合适距离进行用户提示。
  8. 如权利要求7所述的装置，其特征在于，所述实际距离是否符合所述合适距离的判断方式为：
    所述合适距离为一个距离区间，所述实际距离落入该区间则判断出所述实际距离符合所述合适距离；或
    所述合适距离为一个距离值，所述实际距离等于所述合适距离则判断出所述实际距离符合所述合适距离；或
    所述合适距离为一个距离值，所述实际距离与所述合适距离的差值在设定阈值范围内则判断出所述实际距离符合所述合适距离。
  9. 如权利要求7所述的装置，其特征在于，所述提示模块还用于在所述实际距离符合所述合适距离后，根据所述用户的图像中左右眼的像素坐标，确定左右眼在水平方向是否位于合适区域，并进行用户提示。
  10. 如权利要求7所述的装置，其特征在于，所述装置还包括水平调整模 块，用于在获取所述用户的图像后，识别用户两个瞳孔的位置，若判断出两个瞳孔的纵坐标不一致，则对用户进行提示。
