Summary:A computer-implemented method for detecting a head pose in a vehicle including receiving images of a vehicle occupant located in the vehicle from an imaging device and selecting facial feature pointsfrom a plurality of facial feature points extracted from the images. The method includes calculating a head pose point based on normalizing the selected facial feature points, determining the head pose based on a change in position of the head pose point over a period of time T, and controlling one or more vehicle systems of the vehicle based on the head pose. 检测注意力分散和向下垂直头部姿势的系统和方法。种用于在车辆中检测头部姿势的计算机实现的方法包括从成像设备接收位于所述车辆中的车辆乘员的图像，以及从提取自所述图像的多个面部特征点中选择面部特征点。所述方法包括：基于对所述选择的面部特征点进行归化来计算头部姿势点；基于所述头部姿势点的位置在时间段T内的变化来确定所述头部姿势；以及基于所述头部姿势来控制所述车辆的个或多个车辆系统。
