Abstract

The invention discloses a real-time fatigue driving detection method. The method comprises the following steps: 1, acquiring image data from a video shot by a camera; 2, according to the obtained image data, performing state recognition, including face recognition, and completing eye and mouth positioning and classification; 3, calculating various parameters, and forming a multi-parameter composite criterion; 4, performing fatigue detection: determining whether fatigue exists or not according to a multi-parameter composite criterion, and if not, turning to the step 1; and if so, giving an alarm. According to the technology of the invention, an SSD (Single Shot MultiBox Detector) network is mainly utilized to identify faces in video images and position and classify eyes and mouths, and thena PERCLOS method, blinking frequency, yawn frequency and the like are utilized as fatigue judgment standards. In view of the detection effect of the SSD network, the technology of the invention has higher detection accuracy and real-time performance.

Description

technical field [0001] The invention belongs to the field of computer graphics and image processing, and in particular designs a driver fatigue detection method. Background technique [0002] Video image processing is one of the research focuses and hotspots in the field of computer science, and has made great progress. Fatigue driving detection based on image processing is the focus of scholars, and it is also the field involved in this patent application. [0003] The existing face recognition and fatigue driving detection algorithms mainly include AdaBoost algorithm, PERCLOS method and so on. It mainly uses the AdaBoost-based face detection and the active shape model of human eye positioning to detect the position of the human eye, and then uses the PERCLOS method to judge the opening and closing state of the driver's eyes. For example, the detection rate based on AdaBoost classifier and PERCLOS standard implemented by Xiao Qing can reach 86%-93%, but the processing spe...
