Problems solved by technology

There is a serious problem with this method: for drivers without any additional objects on the face, traditional eye detection and positioning methods based on machine vision can better locate the eye area, but for drivers wearing various styles of glasses/sunglasses For the driver, because the glasses affect some parameters of

Embodiment Construction

[0016] The present invention will be further described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0017] The design concept of the embodiment of the present invention is: obtain the real-time image of the driver's head through the camera, use the similarity in the frame structure of various glasses, first search the nose frame area, judge whether the driver wears glasses, and then according to the nose frame area The search results determine the corresponding human eye area positioning method. When the nose bridge area is searched, the human eye area acquisition method based on the nose bridge area is used. When the nose bridge area is not found, the head image of the driver is located. Directly locate the human eye area. Therefore, it overcomes the defect that the human eye is directly searched in the traditional human eye search method based on machine vision and is easily interfered by objects such as glasses / sunglasses.

Abstract

The invention discloses a fatigue driving detection method and device. The method comprises the following steps of: locating a face region based on a collected head image of a driver; detecting a nose frame region based on the face region, wherein the nose frame region is a region where a connecting part for connecting a left spectacle frame and a right spectacle frame of a pair of spectacles is spanned on the nose bridge of the driver; if detecting the nose frame region, acquiring an eye region based on the nose frame region; if not detecting the nose frame region, locating the eye region based on the face region; analyzing the closing state of eyes based on the eye region, and comparing the closing state of the eyes with a fatigue standard to judge whether the driver is in a fatigue state. Through the scheme for searching the nose frame region, the defect that directly searching eyes in the traditional eye searching method based on machine vision is easy to be interfered by objects such as spectacles/sunglasses and the like is overcome, and the accuracy for judging the close of the eyes of the driver is improved, furthermore, the accuracy for judging fatigue driving is improved,and better adaptability is obtained.

Description

technical field [0001] The invention relates to the technical field of safe driving of vehicles, in particular to the technical field of fatigue driving monitoring. Background technique [0002] The development direction of advanced automotive safety technology is active safety technology, that is, through the detection of the driver, vehicle and surrounding environment, it can judge possible dangers in advance and take preventive measures. The driver fatigue driving warning technology is a typical active safety technology. When the driver is in a state of fatigue, the ability to perceive the surrounding environment, the ability to judge the situation, and the ability to control the vehicle are all reduced to varying degrees, and traffic accidents are prone to occur. Therefore, the research and development of high-performance driver attention real-time monitoring and early warning technology can effectively reduce the hidden dangers caused by fatigue driving and other behav...
