The invention discloses an automobile driving posture detection method based on multi-view vision. The automobile driving posture detection method comprises the following steps: installing that a plurality of camera modules in a cockpit; reading and calibrating the position of the head of the person in the cockpit, acquiring a stereoscopic vision image of the face area, calculating parallax, and correcting the image of the head area; selecting a reference point, and obtaining image pixels and three-dimensional coordinates of the reference point; calibrating the distance relationship between the four reference points and the camera module; carrying out stereo matching on the stereo coordinate positions of the four reference points and the head area image, obtaining image parallax accordingto the matching point pairs, and carrying out calculation and three-dimensional reconstruction to obtain three-dimensional point cloud information; and comparing the head three-dimensional informationobtained by real-time detection and calculation to obtain driver posture information, and detecting and judging. The invention can monitor the head and face information of a person in a cockpit in real time, adapts to environmental changes, is high in detection accuracy, analyzes the posture of a driver, gives an alarm for an abnormal posture, is high in processing efficiency, and guarantees thesafety in a driving process.

    一种基于多目视觉的汽车驾驶姿态检测方法,包括以下步骤:在驾驶舱内安装若干个摄像头模块;对驾驶舱中人头部的位置进行读取和标定,对人脸区域获取立体视觉图像并计算视差,进行头部区域的图像校正;选取参考点,获取其图像像素与立体坐标;对四个参考点和摄像机模组的距离关系进行标定;对四个参考点的立体坐标位置以及头部区域图像进行立体匹配,根据匹配点对得到图像视差,计算并进行三维重建得到三维点云信息;根据实时检测计算得到的头部三维信息对比得到驾驶员姿态信息,检测判定。本发明可实时监测驾驶舱内人的头部脸部信息,适应环境变化,检测准确性高,分析驾驶员姿态,对不正常姿态进行提醒报警,处理效率高,保证驾驶过程中的安全。
