The invention discloses a novel drunk driving behavior early warning recognition method and system, and the method comprises the steps: building a red face database, carrying out the analysis and processing of a face image obtained on site, judging whether a detected target object is suspected of drunk driving or not, and transmitting an early warning signal if the detected target object is suspected of drunk driving; and if not, returning to continue to collect the on-site face image. According to the method, by means of the red face recognition algorithm and the face recognition algorithm based on the database, real-time drunk driving behavior recognition can be achieved, drinking behavior recognition within a period of time can also be achieved, and the blank that recognition is missed due to the fact that the red face passes too fast but the concentration of residual alcohol in the body is still high is filled. The method based on red face detection can obtain higher drunk driving behavior recognition accuracy, and the method effectively expands the time range of drunk driving behavior recognition in combination with a face recognition method based on a database.

    本发明公开了一种新型的酒后驾驶行为预警识别方法及系统,通过构建红脸数据库,将现场获取的人脸图像进行分析处理,判断被检测的目标对象是否有酒驾嫌疑,如果是,则发出预警信号;如果否,则返回继续采集现场人脸图像。本方法借助于红脸识别算法和基于数据库的人脸识别算法,不仅可以实现实时的酒后驾驶行为识别,还能实现一段时间范围内的饮酒行为识别,填补了红脸消逝过快但是体内酒精残留浓度仍然较高而导致漏识别的空白。基于红脸检测的方法可以获得更高的酒后驾驶行为识别准确率,结合基于数据库的人脸识别方法,该方法有效拓展了酒后驾驶行为识别的时间范围。
