在步骤S11中，获取车舱内的乘员的影像信息。
在步骤S12中，基于所述影像信息检测所述乘员的目标部位的旋转角，其中，所述目标部位为头部、脸部或者眼睛。
在步骤S13中，响应于根据所述目标部位的旋转角确定所述目标部位转向所述车舱内的车载显示屏，控制所述车载显示屏点亮。
本公开实施例提供的车载显示屏的控制方法可以应用于设置有车载显示屏的各种类型的交通工具中。例如，所述交通工具可以是车辆，也可以是船舶或者飞机等用于载人或者载货的交通工具。其中，车辆可以是私家车或者营运车辆，例如，营运车辆可以是共享汽车、网约车、出租车、公交车、校车、长途货车、短途货车、长途客车、短途客车、火车、地铁、有轨电车等。

在本公开实施例中，所述车舱内的车载显示屏的数量可以为一个或两个以上。在所述车舱内的车载显示屏的数量为两个以上的情况下，可以针对所述车舱内的各个车载显示屏分别执行本公开实施例 提供的车载显示屏的控制方法。当然，也可以仅针对所述车舱内的部分车载显示屏执行所述车载显示屏的控制方法，在此不作限定。所述车载显示屏可以为设置在所述车舱内的任意显示屏。例如，所述车载显示屏可以为中控台屏幕、仪表盘、A柱显示屏、用于供乘客使用的后排显示屏等等。
在本公开实施例中，所述目标部位表示所述乘员身上进行旋转角检测的部位。在本公开实施例中，可以基于所述车舱内的乘员的影像信息中的一个或多个图像，检测乘员的目标部位的旋转角。例如，可以预先训练用于检测目标部位的旋转角的神经网络，在所述神经网络训练完成后，将所述影像信息中的至少一个图像输入所述神经网络，经由所述神经网络得到所述乘员的目标部位的旋转角。又如，可以预先设计用于确定目标部位的旋转角的函数，通过该预先设计的函数得到与所述影像信息对应的目标部位的旋转角。
