The invention discloses a dangerous driving behavior recognition method, device and system and a computer readable storage medium. The method comprises the following steps: acquiring a to-be-recognized near-infrared image, and calling a face detector to perform face detection on the to-be-recognized near-infrared image to obtain a face region image in a to-be-recognized driver image; calling a face key point detection model to detect the face area to obtain face key point data; aligning a face in the face region image, and calculating a head attitude angle in the aligned face region image based on a head attitude estimation algorithm and the face key point data; calling a human face state detection model to analyze the human face region image to obtain human eye closing state features andmouth action features; and generating a dangerous driving behavior judgment result according to the head attitude angle, the human eye closing state characteristics and the mouth action characteristics, so that the detection speed and the detection accuracy of dangerous driving behaviors can be improved, and the traffic accident occurrence probability is effectively reduced.

    本申请公开了一种危险驾驶行为识别方法、装置、系统及计算机可读存储介质。其中,方法包括获取待识别近红外图像,调用人脸检测器对待识别近红外图像进行人脸检测,得到待识别驾驶员图像中的人脸区域图像;调用人脸关键点检测模型对人脸区域进行检测,得到人脸关键点数据;对人脸区域图像中人脸进行对齐处理,基于头部姿态估计算法和人脸关键点数据计算对齐后的人脸区域图像中头部姿态角;调用人脸状态检测模型对人脸区域图像进行分析,得到人眼闭合状态特征和嘴部动作特征;根据头部姿态角、人眼闭合状态特征和嘴部动作特征生成危险驾驶行为判决结果,可提高危险驾驶行为的检测速度和检测准确率,有效降低交通事故发生概率。
