 本发明的实施方式
应当理解，此处所描述的具体实施例仅用以解释本申请，并不用于限定本申请。
参照图1，图1为本申请实施例方案涉及的硬件运行环境的电视结构示意图。
如图1所示，该电视可以包括：处理器1001，例如中央处理器（Central Processing Unit，CPU），通信总线1002、用户接口1003，网络接口1004，存储器1005。其中，通信总线1002用于实现这些组件之间的连接通信。用户接口1003可以包括显示屏（Display）、输入单元比如键盘（Keyboard），可选用户接口1003还可以包括标准的有线接口、无线接口。网络接口1004可选的可以包括标准的有线接口、无线接口（如无线保真（Wireless-Fidelity，Wi-Fi）接口）。存储器1005可以是高速的随机存取存储器（Random Access Memory，RAM）存储器，也可以是稳定的非易失性存储器（Non-Volatile Memory，NVM），例如磁盘存储器。存储器1005可选的还可以是独立于前述处理器1001的存储装置。
本领域技术人员可以理解，图1中示出的结构并不构成对电视的限定，可以包括比图示更多或更少的部件，或者组合某些部件，或者不同的部件布置。
如图1所示，作为一种存储介质的存储器1005中可以包括操作系统、网络通信模块、用户接口模块以及基于雷达的电视曲率调整程序。
在图1所示的电视中，网络接口1004主要用于与网络服务器进行数据通信；用户接口1003主要用于与用户进行数据交互；本申请电视中的处理器1001、存储器1005可以设置在电视中，所述电视通过处理器1001调用存储器1005中存储的基于雷达的电视曲率调整程序，并执行本申请实施例提供的基于雷达的电视曲率调整方法。
本申请实施例提供了一种基于雷达的电视曲率调整方法，参照图2，图2为本申请一种基于雷达的电视曲率调整方法第一实施例的流程示意图。
本实施例中，所述基于雷达的电视曲率调整方法包括以下步骤：
步骤S10：获取全局点云阵列。
需要说明的是，本实施例的执行主体为电视，电视所采用的屏幕为柔性屏，例如柔性OLED。电视上设置有多线束激光雷达传感器，多线束激光雷达传感器中包括激光发射器和接收器，激光发射器和接收器竖向排列形成一个面，位于电视底部正中央位置。
可以理解的是，激光雷达传感器对比图像传感器识别观看目标，激光雷达传感器有以下几个优点：抗光表现好，在黑夜无灯光或者强光环境下，能精准测量观看目标的距离与角度，稳定性与可靠性搞；而图像传感器容受外界光线的影响，成像质量不稳定导致测量不精准；图像传感器呈现的是2D图像，从2D到3D进行定位，测量观看目标方位距离数据需要多个摄像头，算法复杂测位比较困难，而采用激光雷达传感器只需要一个传感器就能够准确获取目标的三维信息，精准的测量目标方位距离；激光雷达传感器测量范围广、精度高，可基于电视上下左右360°发射雷达波束，精度可达1CM，所以对运动目标状态的判断激光雷达优于图像传感器。
在一实施例中，为了更好的获得全局点云阵列，步骤S10包括：确定全局视场角；根据所述全局视场角获取各点云阵列组；根据各点云阵列组生成全局点云阵列。
可以理解的是，由于用户是坐在电视前方观看，因此全局点云阵列是指电视前方180°视角范围内的点云阵列，因此，全局视场角是指电视前方180°。
在具体实现中，电视的多线束激光雷达传感器模块可内置10组激光发射器和接收器，基于垂直视场角40°、垂直分辨率10°方式进行垂直排列。多线束激光雷达进行探测时，脉冲驱动电路同时驱动10组激光发射器发射10个持续时间极短但瞬时功率非常高的竖直排列激光脉冲组。激光发射器开始发射激光脉冲组后，多线束激光雷达传感器下方的旋转机构子模块，基于电视中心位置水平的全局视场角180°、水平分辨率0.2°、10Hz(1秒扫描10次)，控制线束激光雷达传感器从0°~180°旋转方式进行发射与接收激光脉冲，即10*180/0.2=9000，1秒扫描10次，每一次扫描得到一组点云阵列组，1周期得到90000pts/s采集点数，即全局点云阵列。
步骤S20：根据所述全局点云阵列确定观看目标的距离方向信息。
需要说明的是，观看目标进入激光脉冲探测范围，激光发射器的激光脉冲照射到观看目标以后，通过目标的反射光线汇聚到激光接收器上，因此，全局点云阵列中包括观看目标的点云数据。
可以理解的是，雷达测距原理如图3所示，反射到激光接收器的反射光线，通过光电器件转化为光电流，输送给回波信号处理电路。回波信号处理电路将光电流转化为电压信号，经过一级或数级放大并调理后，得到一个回波信号对应的电脉冲，通过多线束激光雷达传感器测量回波信号对应的电脉冲从发射到返回的全程所用的时间为“tr”。根据距离公式：R=c·tr/2（其中R表示目标到电视雷达的单程距离，单位为m；tr表示激光脉冲往返观看目标与雷达之间的时间间隔，单位为s；c为光速）得出一个反射点的距离信息。
同上述方式，计算得出观看目标上其他各反射点的距离信息，再将这些距离信息与该点对应光束指向的方位角和俯仰角结合得到目标的距离-角度-角度，观看目标的点云数据。将各个反射点的距离和方位角，各自进行相加并取平均值，从而得到观看目标最终的距离以及方位角，即距离方向信息。
步骤S30：根据所述距离方向信息确定对应的曲率值以及方位值。
在具体实现中，电视上还设置有曲率调整模块，可以改变电视屏幕的曲率，电视上还设置有可转动底座，可以调整电视屏幕的方向。
可以理解的是，电视屏幕的曲率是通过将曲线形成一个完整的圆弧，测量其半径而获得，当测量曲面显示屏时，“R”值表示曲率的半径，例如：一个4200R曲率的曲面电视可以形成一个半径为4200MM的圆圈。如果以平均观影距离3.5-4米来推算，此时观看者的眼睛恰好处于这个圆形的中心区域，使得人眼到屏幕各点距离相等，获得最佳的观看体验。因此，当根据距离方向信息确定观看目标的的距离后，则可以根据距离确定电视屏幕的曲率需要如何调整。例如，当观看目标距离电视屏幕4.5米时，此时需要调整电视屏幕的曲率为4500R，即曲率值为4500R。以上仅为举例说明，本实施例不加以限制。
在一实施例中，步骤S30包括：根据所述距离方向信息确定所述观看目标与所述电视屏幕的距离；根据所述距离确定对应的曲率值。
需要说明的是，为了方便电视的曲率调节，电视的曲率模式可以根据观看目标的距离进行设置，距离与曲率值的关系如下表1所示：
表1
距离 1~2M 2~3M 3~4M 4~5M
曲率值 1800R 2500R 3000R 4200R
可以理解的是，当观看目标与电视的距离为1至2米时，则将电视曲率值为1800R，以此类推。
步骤S40：根据所述曲率值调整电视屏幕的曲率。
在具体实现中，曲率调整模块中包含伸缩结构，当曲率调整模块接收到曲率值后，根据曲率值控制伸缩结构变化，从而将电视屏幕调整至对应的曲率。
步骤S50：根据所述方位值调整所述电视屏幕的方位角度。
可以理解的是，可转动底座与电视屏幕连接，用于控制电视屏幕的方向角度，当根据距离方向信息确定观看目标的方位值后，方位值对应唯一的方位角度，从而确定观看目标的方位角度，此时底座转动带动电视屏幕转动至对应的方位角度。
需要说明的是，用于通常电视会摆放在距离电视墙较近的位置，而电视与电视墙的距离会限制电视机的转动，并且若电视转动时碰到墙壁可能会损坏电视，因此，电视屏幕后方两侧设置有距离传感器，用于检测电视后方与障碍物或墙壁的距离，当距离小于距离阈值时，则向可转动底座发送停止转动的指令，从而避免电视碰上障碍物而引起的损坏。
在一实施例中，为了更好的提升用户体验，步骤S50之后，还包括：当检测到所述观看目标移动时，获取所述观看目标的停留时长；当所述停留时长超过预设时长时，获取所述观看目标的当前距离方向信息；根据所述当前距离方向信息调整所述电视屏幕的曲率以及方位角度。
在具体实现中，观看目标会因自身原因而移动，因此需要持续监测观看目标的位置，但若观看目标仅是短暂移动又返回原位时，电视屏幕不停地转动则会影响用户体验，因此，需要持续检测观看目标在同一位置的停留时长，例如当预设时长为30秒时，当停留时长超过30秒时，则通过全局点云整列确定观看目标当前的距离方向信息，并根据距离方向信息调整电视屏幕的曲率以及方位角度。观看目标位置的监测可通过红外摄像头进行判断。
本实施例通过获取全局点云阵列；根据所述全局点云阵列确定观看目标的距离方向信息；根据所述距离方向信息确定对应的曲率值以及方位值；根据所述曲率值调整电视屏幕的曲率；根据所述方位值调整所述电视屏幕的方位角度。通过上述方式，电视上的雷达获取电视机前方的全局点云阵列，从而确定观看者与电视之间的距离以及角度，将电视的屏幕调整为距离对应的曲率，并根据角度转动电视屏幕，从而使电视达到最佳的观看效果，从而提升了用户体验。
参考图4，图4为本申请一种基于雷达的电视曲率调整方法第二实施例的流程示意图。
基于上述第一实施例，本实施例基于雷达的电视曲率调整方法在所述步骤S20，包括：
步骤S21：根据所述全局点云阵列生成三维环境图像。
可以理解的是，全局点云阵列中包含每个点的三维坐标数据，因此可以根据三维坐标数据建立三维环境图像，三维环境图像中不仅包括观看目标的三维图像，还包括周围环境的三维图像，例如沙发、茶几等。
步骤S22：根据所述三维环境图像确定所述观看目标的三维图像。
需要说明的是，由于每种物体的三维图像特征是不同的，可通过机器学习识别三维环境图像中观看目标的三维图像，因为观看目标的三维图像是人形，预先使用人体观看电视时各形态的三维图像训练机器学习算法，训练后的机器学习算法则可以识别三维环境图像中观看目标的三维图像。
步骤S23：根据所述三维图像确定所述观看目标的距离方向信息。
在一实施例中，为了让用户获得更好的观看体验，步骤S23包括：根据所述三维图像识别所述观看目标的三维人脸图像；根据所述三维人脸图像确定所述观看目标的三维人眼图像；根据所述三维人眼图像确定所述观看目标的眼睛距离以及眼睛方位；根据所述眼睛距离以及所述眼睛方位生成距离方向信息。
可以理解的是，由于观看电视屏幕的是人体的眼睛，而考虑人体的其他部位的位置方向时，可能会影响眼睛的观看体验，因此需要从观看目标的三维图像中确定三维人脸图像，即观看目标脸部的三维图像。
在具体实现中，三维人脸图像中包括面部五官的图像，因此需要从三维人脸图像中识别三维人眼图像，并确定三维人眼图像对应的点云数据，点云数据中包括人眼与电视屏幕的距离（即眼睛距离）以及方位角（即眼睛方位）等信息，从而根据这些信息生成距离方位信息，电视则根据距离方位信息调整曲率以及方位角度。
本实施例通过根据所述全局点云阵列生成三维环境图像；根据所述三维环境图像确定所述观看目标的三维图像；根据所述三维图像确定所述观看目标的距离方向信息。通过上述方式，将观看目标的三维图像从三维环境图像中分离出来，从而可以更准确的确定观看目标的位置。
参考图5，图5为本申请一种基于雷达的电视曲率调整方法第三实施例的流程示意图。
基于上述第一实施例，本实施例基于雷达的电视曲率调整方法在所述步骤S30之后，还包括：
步骤S31：根据所述全局点云阵列确定所述观看目标的人数。
需要说明的是，观看目标可能存在多个，而当多人观看电视，由于坐在不同的位置，电视以曲面进行显示则会影响用户的观看体验，因此需要根据全局点云阵列确定观看目标的人数。可以通过全局点云阵列确定观看目标点云数据集的个数，从而确定观看目标的人数。
步骤S32：当所述人数超过预设人数时，显示直屏提示信息，以供用户进行选择。
可以理解的是，预设人数可为1，当观看目标的人数超过1人时，则在电视上显示是否需要直屏显示的提示信息，用户则可以通过遥控器进行选择。
步骤S33：当接收到直屏选择指令时，将所述电视屏幕调整为直屏。
在具体实现中，当用户选择直屏后，遥控器发送直屏选择指令，电视机则将屏幕调整为直屏，即曲率为0。同时，将电视屏幕转向至正前方。
本实施例中通过根据所述全局点云阵列确定所述观看目标的人数；当所述人数超过预设人数时，显示直屏提示信息，以供用户进行选择；当接收到直屏选择指令时，将所述电视屏幕调整为直屏。通过上述方式，可以确定观看目标的人数，根据人数来调整电视屏幕的曲率，从而进一步提升了用户体验。
