Embodiment Construction

[0043] The following specific examples further illustrate the present invention, but are not intended to limit the present invention.

[0044]Shooting video in a real car can be divided into three situations: wearing myopia glasses during the day, wearing myopia glasses at night and using infrared lights to fill the light, and wearing sunglasses during the day and using infrared penetration. The wavelength of the infrared lamps is 850nm, the irradiation angle of the inner row of infrared lamps is 30 degrees, and the irradiation angle of the outer row of infrared lamps is 45 degrees. When supplementing light at night, turn on the outer infrared lamp. When it is necessary to penetrate the sunglasses, the inner and outer rows of infrared lamps are turned on at the same time to strengthen the intensity of the infrared light, which is beneficial to the penetration of the sunglasses. In order to ensure the diversity of samples, the researchers collected have different characteristi...

Abstract

The invention discloses a method for detecting fatigue of a driver wearing glasses. The method comprises the following steps: positioning human eyes based on positioning of a human face, and finding out a method for positioning eyes insensitive to interference in the process of positioning human eyes in terms of interference of an optical frame and other factors; extracting eye height by adopting a proper processing mode according to characteristics of the image, and calculating the opening degree; and determining the fatigue state of the driver. By adopting the method, according to the situation of the driver wearing glasses, the radial symmetry of strong iris and pupil but weak optical frame is utilized, and the interference of the optical frame is reduced as much as possible when the eyes are positioned; and corresponding measures are adopted according to night, sunglasses transmitted by infrared ray and other situations, the eye height can be effectively calculated, the opening degree of eyes is calculated, and the fatigue of the driver can be correctly determined.

Description

technical field [0001] The invention relates to a fatigue detection method for a driver wearing glasses. Background technique [0002] With the rapid development of the economy, people's material level is also increasing day by day; as a convenient and fast means of transportation, motor vehicles are rapidly entering people's lives. Fatigue driving, speeding, and drunk driving are the three main causes of traffic accidents. [0003] At present, there are relatively mature detection technologies for speeding and drunk driving; therefore, the importance of a mature and robust driver fatigue detection system is even more prominent. Researchers at Carnegie Mellon University proposed the PERCLOS (Percent age of Eyelid Closure over the Pupil overtime) standard. PERCLOS refers to the percentage of eyelid closure time per unit time. A large number of experiments have proved that the PERCLOS standard can well reflect whether the driver is tired or not, so it has become the only fat...
