Description

一种控制视频播放的方法、装置、电子设备及存储介质
本申请要求在2020年5月22日提交中国专利局、申请号为202010443500.8的中国专利申请的优先权，该申请的全部内容通过引用结合在本申请中。

背景技术
随着5G技术的快速推进落地以及短视频等富媒体的出现，让网民获取信息的方式变得更加多样化，同时网民对于如何更智能化地获取并且处理信息的诉求越来越强烈。例如，好看视频App自发布以来，用户在该App中的活动越来越多，对于观看视频体验的要求也会越来越高。
然而，在实践中发现，在移动手机、平板电脑等智能设备播放视频的过程中，当用户需要暂停智能设备当前播放的视频时，用户需要用手点击智能设备的屏幕上的暂停按键，而当用户需要智能设备继续播放视频时，用户又得用手指点击智能设备的屏幕上的播放按键。显然，这种以手指点击屏幕来控制视频播放的方式不仅会降低视频播放的便捷性，还会降低控制视频播放的效率。
在现有的控制视频播放的方法中，通过识别算法只能分析出眼睛动作，包括：眼睛的睁开、闭合、眼睛的转动方向等，因而无法通过上述眼睛动作对视频播放进行更加精准地控制。

具体实施方式
以下结合附图对本申请的示范性实施例做出说明，其中包括本申请实施例的各种细节以助于理解，应当将它们认为仅仅是示范性的。因此，本领域普通技术人员应当认识到，可以对这里描述的实施例做出各种改变和修改，而不会背离本申请的范围和精神。同样，为了清楚和简明，以下的描述中省略了对公知功能和结构的描述。
实施例一
图1是本申请实施例提供的一种控制视频播放的方法的流程示意图，该方法可以由控制视频播放的装置或者电子设备来执行，该装置或者电子设备可以由软件和/或硬件的方式实现，该装置或者电子设备可以集成在任 何具有网络通信功能的智能设备中。如图1所示，控制视频播放的方法可以包括以下步骤：
S101、当至少一个视频在显示屏幕上正在播放或者暂停播放时，采集显示在屏幕前方的用户的当前人脸图像。
在本申请的具体实施例中，当至少一个视频在显示屏幕上正在播放或者暂停播放时，电子设备可以采集显示在屏幕前方的用户的当前人脸图像。较佳地，电子设备可以按照预设周期采集显示在屏幕前方的用户的当前人脸图像。具体地，电子设备可以先获取前置摄像头权限，然后通过增强现实(Augmented Reality，AR)引擎自动地采集显示在屏幕前方的用户的人脸图像。AR技术是一种将虚拟信息与真实世界巧妙融合的技术，广泛运用了多媒体、三维建模、实时跟踪及注册、智能交互、传感等多种技术手段，将计算机生成的文字、图像、三维模型、音乐、视频等虚拟信息模拟仿真后，应用到真实世界中，两种信息互为补充，从而实现对真实世界的“增强”。
S102、基于增强现实的目光追踪方法对当前人脸图像进行解析，确定出用户在显示屏幕上的当前视觉焦点。
在本申请的具体实施例中，电子设备可以基于增强现实的目光追踪方法对当前人脸图像进行解析，确定出用户在显示屏幕上的当前视觉焦点。具体地，基于增强现实的目光追踪方法可以是ARkit目光追踪方法。
S103、根据当前视觉焦点控制至少一个视频在显示屏幕上继续播放或者暂停播放。
在本申请的具体实施例中，电子设备可以根据当前视觉焦点控制至少一个视频在显示屏幕上继续播放或者暂停播放。具体地，若在预设时间段内确定出用户连续眨眼N次，则电子设备可以根据用户在显示屏幕上的当前视觉焦点，确定出当前视觉焦点所在的视频；其中，N为大于1的自然数；当当前视觉焦点所在的视频在显示屏幕上正在播放时，则电子设备可以控制当前视觉焦点所在的视频在显示屏幕上暂停播放；或者，当当前视觉焦点所在的视频在显示屏幕上暂停播放时，则电子设备可以控制当前视觉焦点所在的视频在显示屏幕上继续播放。
需要说明的是，通过上述步骤S101-S103，可以实现多个视频的切换。 例如，假设显示屏幕上有三个视频，分别为视频1、视频2和视频3，其中，视频1和视频2暂停播放，视频3正在播放，电子设备可以先采集显示在屏幕前方的用户的当前人脸图像；然后基于增强现实的目光追踪方法对当前人脸图像进行解析，确定出用户在显示屏幕上的当前视觉焦点，假设当前视觉焦点所在的视频为视频3，则电子设备可以控制视频3继续播放，控制视频1和视频2暂停播放。接着，电子设备还可以继续采集显示在屏幕前方的用户的当前人脸图像；然后基于增强现实的目光追踪方法对当前人脸图像进行解析，确定出用户在显示屏幕上的当前视觉焦点，假设当前视觉焦点所在的视频为视频2，则电子设备可以控制视频2继续播放，控制视频1和视频3暂停播放，从而实现了从视频3到视频2的切换。
本申请实施例提出的控制视频播放的方法，当至少一个视频在显示屏幕上正在播放或者暂停播放时，电子设备可以采集显示在屏幕前方的用户的当前人脸图像；然后基于增强现实的目光追踪方法对当前人脸图像进行解析，确定出用户在显示屏幕上的当前视觉焦点；再根据当前视觉焦点控制至少一个视频在显示屏幕上继续播放或者暂停播放。也就是说，本申请可以通过采集显示在屏幕前方的用户的当前人脸图像，即可通过眼睛精准地控制视频播放。而在现有的控制视频播放的方法中，通过识别算法只能分析出眼睛动作，包括：眼睛的睁开、闭合、眼睛的转动方向等，因而无法通过上述眼睛动作对视频播放进行更加精准地控制。因为本申请采用了基于增强现实的目光追踪方法对当前人脸图像进行解析，确定出用户在显示屏幕上的当前视觉焦点的技术手段，克服了现有技术中通过眼睛动作无法精准地控制视频播放的技术问题，本申请提供的技术方案，可以通过眼睛更加精准地控制视频播放，更加方便用户操作，从而可以有效地提升用户的观看体验；并且，本申请实施例的技术方案实现简单方便、便于普及，适用范围更广。

S201、当至少一个视频在显示屏幕上正在播放或者暂停播放时，采集显示屏幕前方的用户的当前人脸图像。
S202、基于增强现实的目光追踪方法对当前人脸图像进行解析，确定出用户的左眼目光对应与显示屏幕的交点以及用户的右眼目光与显示屏幕的交点。
在本申请的具体实施例中，电子设备可以基于增强现实的目光追踪方法对当前人脸图像进行解析，确定出用户的左眼目光与显示屏幕的交点以及用户的右眼目光与显示屏幕的交点。具体地，电子设备可以先通过用户对应的左眼转换模型(Left Transform)和右眼转换模型(Right Transform)确定出左眼目光的空间位置和右眼目光的空间位置；然后根据左眼目光的空间位置和右眼目光的空间位置以及预先确定的显示屏幕的空间位置，确定出左眼目光与显示屏幕的交点以及右眼目光与显示屏幕的交点。本申请先确定左眼目光与显示屏幕的交点以及右眼目光与显示屏幕的交点，然后根据左眼目光与显示屏幕的交点以及右眼目光与显示屏幕的交点，可以准确地确定出用户在显示屏幕上的当前视觉焦点，从而可以精准地控制视频继续播放或者暂停播放。
图3是本申请实施例提供的目光追踪技术的实现原理图。如图3所示，电子设备可以先在三维空间中分别添加用户的左眼节点和右眼节点；以及左眼节点对应的左虚拟锚点和右眼节点对应的右虚拟锚点；然后根据左眼节点和左虚拟锚点的空间位置确定出左眼目光的空间位置；根据右眼节点和右虚拟锚点的空间位置确定出右眼目光的空间位置。用户的左眼目光是指用户的左眼节点与左虚拟锚点之间的连线；用户的右眼目光是指用户的右眼节点与右虚拟锚点之间的连线；其中，左眼节点的空间位置可以表示为(x l,y l,z l)；左虚拟锚点的空间位置可以表示为(x’ l,y’ l,z’ l)；右眼节点的空间位置可以表示为(x r,y r,z r)；右虚拟锚点的空间位置可以表示为(x’ r,y’ r,z’ r)。较佳地，用户的左眼节点可以为用户的左眼瞳孔；用户的右眼节点可以为用户的右眼瞳孔。本申请先确定左眼节点和左虚拟锚点的空间位置，以及右眼节点和右虚拟锚点的空间位置，从而可以将左眼节点和左虚拟锚点进行连线，得到用户的左眼目光的空间位置；将右眼节点和右虚拟锚点进行连线，得到用户的右眼目光的空间位置，从而可以准确地确定出左眼目光 与显示屏幕的交点以及右眼目光与显示屏幕的交点。
较佳地，在本申请的具体实施例中，用户人脸与虚拟面板之间的距离可以预先设置，例如，用户人脸与虚拟面板之间的距离可以设置为2米。
S203、根据左眼目光与显示屏幕的交点和右眼目光与显示屏幕的交点，确定用户在显示屏幕上的当前视觉焦点。
在本申请的具体实施例中，电子设备可以根据左眼目光与显示屏幕的交点和右眼目光与显示屏幕的交点，确定用户在显示屏幕上的当前视觉焦点。具体地，电子设备可以将左眼目光与显示屏幕的交点和右眼目光与显示屏幕的交点的中点，作为用户在显示屏幕上的当前视觉焦点。假设左眼目光与显示屏幕的交点的空间位置为(x lm,y lm,z lm)；右眼目光与显示屏幕的交点的空间位置为(x rm,y rm,z rm)；用户在显示屏幕上的当前视觉焦点的空间位置为
Figure PCTCN2021070412-appb-000001
S204、根据用户在显示屏幕上的当前视觉焦点，控制至少一个视频在显示屏幕上继续播放或者暂停播放。
本申请实施例提出的控制视频播放的方法，当至少一个视频在显示屏幕上正在播放或者暂停播放时，电子设备可以采集显示在屏幕前方的用户的当前人脸图像；然后基于增强现实的目光追踪方法对当前人脸图像进行解析，确定出用户在显示屏幕上的当前视觉焦点；再根据当前视觉焦点控制至少一个视频在显示屏幕上继续播放或者暂停播放。也就是说，本申请可以通过采集显示在屏幕前方的用户的当前人脸图像，即可通过眼睛精准地控制视频播放。而在现有的控制视频播放的方法中，通过识别算法只能分析出眼睛动作，包括：眼睛的睁开、闭合、眼睛的转动方向等，因而无法通过上述眼睛动作对视频播放进行更加精准地控制。因为本申请采用了基于增强现实的目光追踪方法对当前人脸图像进行解析，确定出用户在显示屏幕上的当前视觉焦点的技术手段，克服了现有技术中通过眼睛动作无法精准地控制视频播放的技术问题，本申请提供的技术方案，可以通过眼睛更加精准地控制视频播放，更加方便用户操作，从而可以有效地提升用户的观看体验；并且，本申请实施例的技术方案实现简单方便、便于普及， 适用范围更广。
实施例三
图4是本申请实施例提供的一种控制视频播放的方法的流程示意图。本实施例是在上述实施例的基础上提出的一种可选方案。如图4所示，控制视频播放的方法可以包括以下步骤：
S401、当至少一个视频在显示屏幕上正在播放或者暂停播放时，采集显示在屏幕前方的用户的当前人脸图像。
图5是本申请实施例提供的眼球追踪控制视频播放技术的工作原理图。如图5所示，电子设备可以先获取前置摄像头权限，然后通过AR引擎自动地采集显示在屏幕前方的用户的当前人脸图像；针对采集到的当前人脸图像进行计算，得到用户在显示屏幕上的当前视觉焦点；然后根据当前视觉焦点在展示界面的相对位置来自动地控制展示界面向上滚动或者向下滚动。具体地，若用户在显示屏幕上的当前视觉焦点位于显示屏幕的上半区域，则电子设备可以控制显示屏幕上的展示界面向下滚动；若用户在显示屏幕上的当前视觉焦点位于显示屏幕的下半区域，则电子设备可以控制显示屏幕上的展示界面向上滚动。由此可见，本申请不仅可以通过眼睛控制视频播放，还可以通过眼睛控制展示页面的滚动，从而可以进一步提升用户的使用体验。
S402、通过用户对应的左眼转换模型和右眼转换模型确定出左眼目光的空间位置和右眼目光的空间位置。
在本申请的具体实施例中，电子设备可以通过用户对应的左眼转换模型和右眼转换模型确定出左眼目光的空间位置和右眼目光的空间位置。具体地，用户的左眼目光是指用户的左眼节点与左虚拟锚点之间的连线；用户的右眼目光是指用户的右眼节点与右虚拟锚点之间的连线；较佳地，用户的左眼节点可以为左眼瞳孔；用户的右眼节点可以为右眼瞳孔；左眼瞳孔的空间位置可以表示为(x l,y l,z l)；左虚拟锚点的空间位置可以表示为(x’ l,y’ l,z’ l)；右眼瞳孔的空间位置可以表示为(x r,y r,z r)；右虚拟锚点的空间位置可以表示为(x’ r,y’ r,z’ r)。
较佳地，在本申请的具体实施例中，用户人脸与虚拟面板之间的距离 可以预先设置，例如，用户人脸与虚拟面板之间的距离可以设置为2米。
S403、根据左眼目光的空间位置和右眼目光的空间位置以及预先确定的显示屏幕的空间位置，确定出左眼目光与显示屏幕的交点以及右眼目光与显示屏幕的交点。
在本申请的具体实施例中，电子设备可以根据左眼目光的空间位置和右眼目光的空间位置以及预先确定的显示屏幕的空间位置，确定出左眼目光与显示屏幕的交点以及右眼目光与显示屏幕的交点。具体地，显示屏幕的空间位置可以用显示屏幕所在的平面来表示；由于左眼目光以及右眼目光与显示屏幕所在的平面不相交，因此左眼目光和右眼目光分别与显示屏幕所在的平面存在一个交点。
S404、根据左眼目光与显示屏幕的交点和右眼目光与显示屏幕的交点，确定用户在显示屏幕上的当前视觉焦点。
S405、根据用户在显示屏幕上的当前视觉焦点，控制至少一个视频在显示屏幕上继续播放或者暂停播放。
在本申请的具体实施例中，电子设备采集到的当前人脸图像中可以包括一个用户的人脸，也可以包括多个用户的人脸；若当前人脸图像只包括一个用户的人脸，则电子设备可以将该用户确定为控制至少一个视频在显示屏幕上继续播放或者暂停播放的用户；若当前人脸图像中包括多个用户的人脸，则电子设备可以在多个用户中确定一个用户作为控制至少一个视频在显示屏幕上继续播放或者暂停播放的用户。例如，若当前人脸图像中包括多个用户的人脸，则电子设备可以将靠近显示屏幕的中心位置的用户确定为控制至少一个视频在显示屏幕上继续播放或者暂停播放的用户。由此可见，本申请不仅可以针对一个人脸的图像进行识别，还可以针对多个人脸的图像进行识别，在各种观看场景中均可以采用本申请提供的技术方案，从而可以扩大本申请的使用范围。
本申请实施例提出的控制视频播放的方法，当至少一个视频在显示屏幕上正在播放或者暂停播放时，电子设备可以采集显示在屏幕前方的用户的当前人脸图像；然后基于增强现实的目光追踪方法对当前人脸图像进行解析，确定出用户在显示屏幕上的当前视觉焦点；再根据当前视觉焦点控制至少一个视频在显示屏幕上继续播放或者暂停播放。也就是说，本申请 可以通过采集显示在屏幕前方的用户的当前人脸图像，即可通过眼睛精准地控制视频播放。而在现有的控制视频播放的方法中，通过识别算法只能分析出眼睛动作，包括：眼睛的睁开、闭合、眼睛的转动方向等，因而无法通过上述眼睛动作对视频播放进行更加精准地控制。因为本申请采用了基于增强现实的目光追踪方法对当前人脸图像进行解析，确定出用户在显示屏幕上的当前视觉焦点的技术手段，克服了现有技术中通过眼睛动作无法精准地控制视频播放的技术问题，本申请提供的技术方案，可以通过眼睛更加精准地控制视频播放，更加方便用户操作，从而可以有效地提升用户的观看体验；并且，本申请实施例的技术方案实现简单方便、便于普及，适用范围更广。
实施例四
图6是本申请实施例提供的一种控制视频播放的方法的流程示意图。本实施例是在上述实施例的基础上提出的一种可选方案。如图6所示，控制视频播放的方法可以包括以下步骤：
S601、当至少一个视频在显示屏幕上正在播放或者暂停播放时，采集显示在屏幕前方的用户的当前人脸图像。
在本申请的具体实施例中，当至少一个视频在显示屏幕上正在播放或者暂停播放时，电子设备可以采集显示在屏幕前方的用户的当前人脸图像。具体地，电子设备可以通过采样率算法确定出人脸图像的采样率；然后按照该采样率采集显示在屏幕前方的用户的人脸图像，将每次采集到的人脸图像作为当前人脸图像。
S602、基于增强现实的目光追踪方法对当前人脸图像进行解析，确定出用户在显示屏幕上的当前视觉焦点。
在本申请的具体实施例中，电子设备还可以通过焦点位置纠偏算法对确定出的当前视觉焦点进行纠偏。由于每个人的人脸模型以及瞳孔在眼部转动幅度和位置的关系都是不一样的，本申请利用深度学习技术，可以对采集到的当前人脸图像进行模型训练，从而能够得到更准确的位置。虽然千人千面，但是本申请通过深度学习技术，也能做到每个人的焦点位置的相对准确。
较佳地，在本申请的具体实施例中，电子设备还可以通过焦点数据去噪算法对确定出的当前视觉焦点进行去噪。由于瞳孔位置的变化频率是非常高的，某个采样数据的异常可能导致整个焦点位置的抖动，通过去噪算法可以设置阈值，把不符合预期的采样数据丢弃掉。
S603、若在预设时间段内确定出用户连续眨眼N次，则根据当前视觉焦点确定其所在的视频；其中，N为大于1的自然数。
在本申请的具体实施例中，若在预设时间段内确定出用户连续眨眼N次，则电子设备根据用户在显示屏幕上的当前视觉焦点，确定出当前视觉焦点所在的视频；其中，N为大于1的自然数。当当前视觉焦点所在的视频在显示屏幕上正在播放时，则电子设备可以控制当前视觉焦点所在的视频在显示屏幕上暂停播放；或者，当当前视觉焦点所在的视频在显示屏幕上暂停播放时，则电子设备可以控制当前视觉焦点所在的视频在显示屏幕上继续播放。本申请中的预设时间段可以是预先设定一个比较短的时间段，例如，预设时间段可以为1秒，设置预设时间段的目的是确定用户是正常眨眼还是要发出控制指令，以防止电子设备将用户正常的眨眼与发出控制指令相混淆，从而影响用户正常观看。例如，当某个视频在显示屏幕上正在播放时，用户可以在1秒内眨眼两次，表示用户发出暂停播放的指令，当电子设备在检测出用户在1秒内眨眼两次时，视为接收到了用户发出的暂停播放的指令，此时控制该视频在显示屏幕上暂停播放；当某个视频在显示屏幕上暂停播放时，用户可以在1秒内眨眼两次，表示用户发出继续播放的指令，当电子设备在检测出用户在1秒内眨眼两次时，视为接收到了用户发出的继续播放的指令，此时控制该视频在显示屏幕上继续播放。
较佳地，在本申请的具体实施例中，若电子设备通过解析当前人脸图像无法确定当前视觉焦点，则电子设备可以将显示屏幕的亮度值降低预定数值。具体地，若电子设备在一个预设周期内，通过解析当前人脸图像无法确定出用户的当前视觉焦点，则电子设备可以将显示屏幕的亮度值降低一个单位值；若电子设备在多个预设周期内，通过解析当前人脸图像无法确定出用户的当前视觉焦点，则电子设备可以将显示屏幕的亮度值降低多个单位值，从而可以达到动态节电的目的。
S604、当当前视觉焦点所在的视频在显示屏幕上正在播放时，则控制 当前视觉焦点所在的视频在显示屏幕上暂停播放；或者，当当前视觉焦点所在的视频在显示屏幕上暂停播放时，则控制当前视觉焦点所在的视频在显示屏幕上继续播放。
本申请实施例提出的控制视频播放的方法，当至少一个视频在显示屏幕上正在播放或者暂停播放时，电子设备可以采集显示在屏幕前方的用户的当前人脸图像；然后基于增强现实的目光追踪方法对当前人脸图像进行解析，确定出用户在显示屏幕上的当前视觉焦点；再根据当前视觉焦点控制至少一个视频在显示屏幕上继续播放或者暂停播放。也就是说，本申请可以通过采集显示在屏幕前方的用户的当前人脸图像，即可通过眼睛精准地控制视频播放。而在现有的控制视频播放的方法中，通过识别算法只能分析出眼睛动作，包括：眼睛的睁开、闭合、眼睛的转动方向等，因而无法通过上述眼睛动作对视频播放进行更加精准地控制。因为本申请采用了基于增强现实的目光追踪方法对当前人脸图像进行解析，确定出用户在显示屏幕上的当前视觉焦点的技术手段，克服了现有技术中通过眼睛动作无法精准地控制视频播放的技术问题，本申请提供的技术方案，可以通过眼睛更加精准地控制视频播放，更加方便用户操作，从而可以有效地提升用户的观看体验；并且，本申请实施例的技术方案实现简单方便、便于普及，适用范围更广。
