本实施例提供一种自动识别用户状态，并根据用户状态自动进行电视时移控制的方法，所述电视时移控制方法应用于电视时移控制系统，所述电视时移控制系统包括：电视机、摄像头模块、识别模块及时移控制模块。其中，本实施例的电视机为通过接收外界电视信号并根据电视信号播放电视节目的设备，包括电源系统、控制系统以及视听系统等部分；摄像头模块与电视机相连，用于在电视机启动时对电视机可视范围内的区域进行拍摄获得拍摄图片并发送至电视机；识别模块为开发基于人体检测与识别技术的处理模块，与电视机和时移控制模块相连，可以从电视机中获取摄像头模块拍摄的图片中的人体特征信息或者其他人体特征信息并进行分析，并将人体特征信息作为用户的身份信息从而识别和区分不同的用户，并根据对图片的分析发送控制指令至时移控制模块；时移控制模块与电视机及识别模块相连，可以接收并响应识别模块发送的控制指令，获取当前电视播放节目的的电视信号，根据该电视信号进行录像，并控制电视机播放的节目内容，时移控制模块可以是基于PVR文件系统的时移控制模块。在本实施例中，摄像头模块、识别模块或者时移控制模块可以配置在电视机内部，也可以在使用时在电视机外部分别与电视机通过数据线相连，也可以把该三个部分集成到一个模块中，在使用时再把该模块与电视相连。本实施例的具体实现过程如下各步骤所述。
步骤S10，所述电视机通过所述摄像头模块获取预设区域的拍摄图片，并将所述图片发送至所述识别模块；
在本实施例中，摄像头可以安装在电视机的正上方或者正下方等位置，以朝向电视机屏幕正前方的方向安装，预设区域指的是电视机前方的预设范围内的空间区域，该空间区域被识别模块识别为用户可以正常观看电视的空间区域，该空间区域也是摄像头能够拍摄的空间区域，预设区域与摄像头的性能和摄像头的安装位置有关，可以根据用户的观看习惯来确定。在本实施例中，摄像头安装设定每隔特定时间拍摄电视前方图像信息。由于所述摄像头是对电视机的可视范围进行拍摄，所以可以根据观看者的观看习惯，以及人眼的生理特性，对摄像头的拍摄范围进行限定。例如，根据观看者观看电视时通常所在的位置区域，以及人眼能清楚的看到电视画面时，距离电视机的最远距离，来限定摄像头的拍摄范围。在一个实施例中，可以限定摄像机的拍摄距离调节小于等于10米，摄像机的拍摄角度为120度以上。摄像头模块可以包括摄像头和数据传输模块，摄像头模块每隔预设时间便拍摄一次，并把拍摄得到的图像发送至电视机。电视机接收到摄像头模块的拍摄图片后，将该图片发送至识别模块。
步骤S20，所述识别模块利用预设算法获取所述图片的图片信息；
基于上述步骤，识别模块接收到电视机发送的图片后根据预设算法获取图片中的信息。该预设算法通过获取图片中特定的特征点来确定图片中用户的特征信息，并根据特征信息对用户进行识别与区分。例如，可以通过人脸识别算法对图片中的人脸进行检测和识别，识别模块在识别区分用户后再根据图片中用户的姿势状态等特征确定用户是否在看电视，例如，分析用户是站立还是坐下的状态，是侧身还是正对朝向电视屏幕，脸部偏离屏幕方向的角度等情况，从而确定用户是否在观看电视。
步骤S30，所述识别模块根据所述图片信息发送控制指令至所述时移控制模块；
基于上述步骤，识别模块对图片进行分析，获取了图片中的人脸特征信息以及状态信息后，根据获取的信息向时移控制模块发送对应的控制信息。当图片中出现某个用户处于低头或侧脸偏离屏幕方向的角度预设角度，以及用户处于站立准备准备离开状态时，识别模块向时移控制模块发送录像指令，使得时移控制模块根据当前电视播放的电视节目电视信号生成录像任务并进行录像。当用户处于正常观看电视的状态，即坐下状态，并且正对屏幕或者侧身角度满足一定的角度范围时，可以判断该用户是否存在对应的正在进行领的录像任务，当该用户存在对应正在进行的任务时，说明该用户之前离开或者处于非观看状态，当前已恢复观看状态，在不考虑其他因素的前提下，可以停止录像，识别模块向时移控制模块发送停止录像指令。
步骤S40，所述时移控制模块根据所述控制指令进行时移控制。
基于上述步骤，时移控制模块接收识别模块发送停止录像指令或者录像指令后进行时移控制。时移控制模块接收到的控制指令为录像指令时，根据当前电视机播放节目的电视信号进行录像，电视机继续根据当前的电视信号进行电视播放。当时移控制模块接收到的控制指令为停止录像指令时，为了更好的用户体验，优选地，时移控制模块先发送提示用户观看回放的提示信息至电视机，当用户接受回放时，时移控制模块根据电视信号继续录像并发送回放指令至电视机，电视机接收回放指令后播放录像缓存里的内容。当用户拒绝回放时，时移控制器发送继续根据电视信号播放的指令至电视机使得电视机根据电视信号继续进行电视播放。
在本实施例中，所述电视时移控制方法应用于电视时移控制系统，所述电视时移控制系统包括：电视机、摄像头模块、识别模块及时移控制模块，所述电视机通过所述摄像头模块获取预设区域的拍摄图片，并将所述图片发送至所述识别模块；所述识别模块利用预设算法获取所述图片的图片信息；所述识别模块根据所述图片信息发送控制指令至所述时移控制模块；所述时移控制模块根据所述控制指令进行时移控制。通过上述方式，对用户拍摄图片，并根据拍摄的图片自动识别用户当前的状态并判断是否进行时移控制，从而解决现有技术在启动时移功能时存在操作不便，用户体验低的问题。
进一步地，参照图3，图3为本发明电视时移控制方法第二实施例流程示意图，基于上述本发明电视时移控制方法实施例，提出本发明的第二实施例。
在本实施例中，步骤S20包括：
步骤S50，所述识别模块利用预设算法获取所述图片中用户的状态信息和用户的人体特征信息，并将用户的人体特征信息作为用户的身份信息；
步骤S30包括：
步骤S60，所述识别模块根据所述状态信息和预设条件确定所述用户的状态；
步骤S70，当所述用户处于非观看状态时，所述识别模块发送录像指令至所述时移控制模块，所述录像指令包括所述用户的身份信息，所述非观看状态包括准备离开状态或非观看朝向状态；
步骤40包括：
步骤S80，所述时移控制模块根据所述录像指令生成录像任务，并根据所述录像任务和所述电视机当前播放节目的电视信号进行录像。
基于上述实施例，在本实施例中，获取图片信息包括获取用户的人体特征信息和用户状态信息，其中人体特征信息可以是人脸特征信息或者人体其他部位的特征信息，以人脸特征信息为例，人脸特征信息通过人脸检测算法来实现，利用人脸识别提取图片中人脸信息时，获取用户的面部图像后，利用核心的算法对其脸部的五官位置、脸型和角度进行计算分析，人脸识别技术基于局部特征区域的单训练样本人脸识别方法。第一步，先对局部区域进行定义；第二步，人脸局部区域特征的提取，依据经过样本训练后得到的变换矩阵将人脸图像向量映射为人脸特征向量；第三步，局部特征选择；后一步是进行分类。分类器多采用组合分类器的形式，每个局部特征对应一个分类器，后可用投票或线性加权等方式得到终识别结果。人脸识别综合运用了数字图像/视频处理、模式识别、计算机视觉等多种技术，核心技术是人脸识别算法。目前人脸识别的算法有4种：基于人脸特征点的识别算法、基于整幅人脸图像的识别算法、基于模板的识别算法、利用神经网络进行识别的算法。
作为人脸识别的第一步，人脸检测所进行的工作是将人脸从图像背景中检测出来，由于受图像背景、亮度变化以及人的头部姿势等因素影响使人脸检测成为一项复杂研究内容。检测定位：检测是判别一幅图像中是否存在人脸，定位则是给出人脸在图像中的位置。定位后得到的脸部图像信息是测量空间的模式，要进行识别工作，首先要将测量空间中的数据映射到特征空间中。采用主分量分析方法，原理是将一高维向量，通过一个特殊的特征向量矩阵，投影到一个低维的向量空间中，表征为一个低维向量，并且仅仅损失一些次要信息。通过对经过检测和定位过的人脸图像进行特征提取操作可以达到降低图像维数，从而可以减小识别计算量，提高识别精度的作用。人脸识别系统采用基于特征脸的主成分分析法（PCA），根据一组人脸训练样本构造主元子空间，检测时，将测试图像投影到主元空间上，得到一组投影系数，再和各已知的人脸图像模式比较，从而得到检测结果。识别模块每次获取了一个新用户的人脸特征信息时，可以把还特征信息作为新的用户身份信息并存储在预设位置，以便后续对该用户的身份及状态进行识别和跟踪，对应的建立时移录像。
识别模块在识别区分用户后再根据图片中用户的姿势状态等特征确定用户是否在看电视，例如，分析用户是站立还是坐下的状态，是侧身还是正对朝向电视屏幕，脸部偏离屏幕方向的角度等情况，从而确定用户是否在观看电视。对于用户状态的判断，可以预先设置判定对应的判定条件，当图片中用户的姿态特征满足某一特定条件时，判定用户处于站立状态，满足另外某一特征时判断用户处于坐下状态。在本实施例中，可以把用户的站立状态判定为准备离开状态。非朝向状态指的是用户视线与用户和电视机之间的连线超过某一预设角度，超过该角度时，用户不能正常的观看电视。用户在不同位置的预设角度可以不同，例如，用户在正对着电视的位置时，朝向偏移较大的角度也可以正常看电视，而用户在越往电视两边的位置时能正常观看电视的角度较小。识别模块从图片中获取了用户的朝向角度信息之后，将用户的朝向角度与对应的预设角度进行对比，判断用户是否处于非观看状态。
当用户处于非观看状态时，识别模块发送录像指令至时移控制模块，录像指令中包含了用户的身份信息，使得时移控制模块根据用户身份信息建立根据不同用户建立以用户图像为区分特征的文件夹来存储录像缓存的录像任务。本实施例的电视信号为电视节目数据外界来源，时移控制模块接收到录像指令后，根据录像指令在本实施例中时移控制模块可以是基于PVR文件系统的时移控制模块，PVR即个人视频录像机，其突出特点是以硬盘作为存储媒介，建立本地的海量缓冲区和巨大的节目存储库，利用数字化处理技术，实现对节目的控制和管理。数字化和存储技术是PVR技术的核心.。PVR技术用于数字电视系统，相对于模拟PVR，它把数字化的工作放在了前端，而不是在每个客户端进行数字化的编码工作.。PVR时移控制过程如下所述，接收机通过高频头解调和解复用模块解复用后得到用户所选中的数字电视节目电视信号数据，在正常观看节目的情况下，解复用得到的电视信号数据同时通过通道1送到解码器进行解码输出视频，进行解码播出。在录像的过程中，电视信号数据从通道2传输到硬盘并存储，当用户进行暂停、后退、慢放等操作时，接收机进入时移状态，通道1切断，解码器通过通道2从硬盘录像数据进行解码输出。在本实施例中，电视机在联网状态时，云端可以用云端进行替换。时移控制模块生成录像任务后，从当前电视节目播放节点的数据开始录像，从当前节点开始对电视数据进行缓存，放在对应的文件夹。
在本实施例中，所述识别模块利用预设算法获取所述图片中用户的状态信息和用户的人体特征信息，并将用户的人体特征信息作为用户的身份信息；所述识别模块根据所述状态信息和预设条件确定所述用户的状态；当所述用户处于非观看状态时，所述识别模块发送录像指令至所述时移控制模块，所述录像指令包括所述用户的身份信息；所述时移控制模块根据所述录像指令生成录像任务，并根据所述录像任务和所述电视机当前播放节目的电视信号进行录像。通过上述方式，获取图片中的用户人体特征信息和状态信息并进行分析，自动识别用户是否在观看电视，进而在用户不观看电视的时候对电视节目进行录像，以便用户进行回看，从而提高用户的观看体验。
进一步地，参照图4，图4为本发明电视时移控制方法第三实施例流程示意图，基于上述本发明电视时移控制方法实施例，提出本发明的第三实施例。
在本实施例中，步骤S60之后还包括：
步骤S90，当所述用户处于观看状态时，所述时移控制模块判断所述身份信息是否存在正在进行的录像任务；
步骤S100，当所述身份信息存在对应的正在进行的录像任务时，所述识别模块发送停止录像指令至所述时移控制模块。
基于上述实施例，在本实施例中，识别模块在对图片的用户特征信息和用户的状态信息进行分析后，还可能得到用户处于观看状态的结果。当用户处于正在观看状态时可能对应两种情况：1）用户当前为本次电视启动后，第一次加入观看，处于观看状态；2）用户在电视启动后的某个时间点加入观看，处于观看状态，中途有事离开或者处于低头、朝向偏离大于预设角度的非观看状态，当前时间重新恢复到观看状态。基于上述实施例，对于上述情况2），时移控制模块在用户处于非观看状态的时间点已建立录像任务并进行录像。在本实施例中识别模块在发送录像指令时可以预先对对应用户身份信息存储在预设位置并进行备注，用户在恢复观看状态后，再向时移控制模块发送停止录像指令，时移控制模块接收到该指令后根据录像情况和用户操作进行响应。
在本实施例中，当所述用户处于观看状态时，所述时移控制模块判断所述身份信息是否存在正在进行的录像任务；当所述身份信息存在对应的正在进行的录像任务时，所述识别模块发送停止录像指令至所述时移控制模块。通过上述方式，识别模块识别出用户处于观看状态时，发送停止录像指令至时移控制模块，根据用户的实际状态，对时移控制作出调整。
进一步地，参照图5，图5为本发明电视时移控制方法第四实施例流程示意图。基于上述实施例，提出本发明的第四实施例。
在本实施例中，步骤S100之后包括：
步骤S110，所述时移控制模块确定接收到所述停止录像指令时所述录像任务的录像时间；
步骤S120，所述电视时移控制系统判断所述录像时间是否小于预设时间；
步骤S130，当所述录像时间小于预设时间时，所述时移控制模块终止所述录像任务并删除对应的录像缓存。
在实际的观看电视场景中，用户的观看姿态不可能一直保持不动，可能会经常发生变化，例如用户可能在观看过程中会作出中途离开取零食或者低头捡东西等动作，一般来说，用户短暂时间内不处于观看状态对用户观看节目不会产生影响，在这些情况下，没必要对电视录像内容进行保存。
在本实施例中，可以预设一时间，例如5秒，用户处于非观看状态的时间小于该预设时间时，可以将缓存的录像删除。具体地，时移控制模块接收到人体检测模块发出的信息，开始录制电视节目。同时启动计时器，记录开始录制时间。时移控制模块接收到人体检测模块发出的停止录制信息，启动计时器，获取当前停止录制时间。计算出录制时长，若用户选择不回看或录制时长小于预设的时间大小，不会对用户的观看体验产生影响，则时移控制模块删除录制缓存。
在本实施例中，所述时移控制模块确定接收到所述停止录像指令时所述录像任务的录像时间；所述电视时移控制系统判断所述录像时间是否小于预设时间；当所述录像时间小于预设时间时，所述时移控制模块终止所述录像任务并删除对应的录像缓存。通过上述方式，时移控制模块接收到停止录像指令时根据录像时间自动作出是否对用户观看节目存在影响的判定，当不影响用户观看节目时自动将缓存录像删除，避免缓存的录像对用户观看节目造成干扰。
进一步地，参照图6，图6为本发明电视时移控制方法第五实施例流程示意图，基于上述本发明电视时移控制方法实施例，提出本发明的第五实施例。
基于上述实施例，在本实施例中，步骤S120之后包括：
步骤S140，当所述录像时间大于或等于预设时间时，所述时移控制模块发送是否进行回放的提示信息至所述电视机；
步骤S150，当所述电视机接收到用户接受回放的请求信息时，所述电视机根据接受回放的请求信息播放对应的缓存录像，并向所述时移控制模块发送继续录像指令，以使得所述时移控制模块根据所述电视信号继续进行录像。
基于上述实施例在本实施例中，若录制市场大于预设的时间大小，对用户观看电视节目产生了影响，则时移控制体系提示用户是否回看错过的电视节目，提示方式可以发送提示回看信息至电视机，使得电视机将该提示信息显示于显示屏，例如，在当前电视机上的电视播放进度为00：50：35时，某个用户重新恢复了观看状态，时移控制模块接收提示信息可以为“检测到上次观看断点为00：38：16，是否进行回放？”在提示信息下方可以设置是否两个对应的选择按钮，以供用户选择接收回放请求或者拒绝回放请求，其中“00：38：16”为在处于非观看状态时的观看进度，也是录像任务的录像开始时间。在本实施例中，用户点击了“是”按钮时，用户接受回放，电视机接收到用户触发的接受回放的请求信息时，从对对应的缓存录像进行播放，从缓存录像的起点，即电视节目实际的进度点00：38：16进行播放，当前并未播放00：50：35之后的节目内容，并向时移控制模块发送继续录像的指令，时移控制模块接收到继续录像指令后继续接收00：50：35之后的进度内容并进行缓存，以便电视机对缓存录像持续地进行播放，使得用户对完整的电视节目进行观看，在本实施例中用户可以通过遥控器上或者电视机上的按钮进行操作来确定接受或者拒绝回放
在本实施例中，当所述录像时间大于或等于预设时间时，所述时移控制模块发送是否进行回放的提示信息至所述电视机；当所述电视机接收到用户接受回放的请求信息时，所述电视机根据接受回放的请求信息播放对应的缓存录像，并向所述时移控制模块发送继续录像指令，以使得所述时移控制模块根据所述电视信号继续进行录像。通过上述方式，当用户接受回放时，时移控制模块控制电视机播放缓存的录像，并继续根据电视信号进行录像，使得用户可以观看完整的电视节目。
进一步的，参照图7，图7为本发明电视时移控制方法第六实施例流程示意图，基于上述本发明电视时移控制方法实施例，提出本发明的第六实施例。
基于上述实施例，在本实施例中，步骤S140之后包括：
步骤S160，当所述电视机接收到用户拒绝回放的请求信息时，所述电视机根据所述电视信号继续进行电视播放，并向所述时移控制模块发送终止所述录像任务的终止指令；
步骤S170，所述时移控制模块根据所述终止指令终止对应的录像任务。
步骤S180，所述时移控制模块删除对应的录像缓存。
基于上述实施例，在本实施例中，当用户点击了“否”按钮时，用户拒绝回放，电视机接收到用户触发的拒绝回放的请求信息，根据当前接收到的电视信号继续进行电视播放。基于以实施例，当用户拒绝回放时，电视机根据电视信号从播放进度点00：50：35开始进行电视播放。由于时移控制模块当前已完成了从00：38：16至00：50：35之间的录像，用户在00：50：35的进度点恢复了观看，因此当前无需再对00：50：35进度点之后的节目内容进行录像，电视机接收到拒绝回放的请求信息进行电视播放的同时，向时移控制模块发送停止录像的指令，时移控制模块接收到该指令后，在对应电视节目进度00：50：35 的进度点停止录像，获得对应录像任务完成的缓存录像，时移控制模块可以将该缓存录像存储在预设位置以便用户可以根据需要进行观看，也可以在预设时间后将该缓存视频删除，以免造成存储空间资源浪费和影响用户后续的观看体验。
在本实施例中，当所述电视机接收到用户拒绝回放的请求信息时，所述电视机根据所述电视信号继续进行电视播放，并向所述时移控制模块发送终止所述录像任务的终止指令；所述时移控制模块根据所述终止指令终止对应的录像任务；所述时移控制模块删除对应的录像缓存。通过上述方式，用户拒绝回放时，电视机继续根据电视信号进行电视播放并终止对应的录像任务，将对应的录像缓存删除，基于用户自身操作进行相应，实现良好的用户互动，提高用户观看体验。
