Abstract

An embodiment of the invention discloses a method for detecting states of drivers in real time. The method includes detecting face regions from video images of the drivers; detecting eye regions and mouth regions from the face regions; normalizing the detected eye regions and the detected mouth regions and matching the eye regions and the mouth regions with preliminarily trained eye and mouth templates so as to determine fatigue states of the drivers; detecting face feature points from the face regions by the aid of local constraint models in real time; three-dimensionally modeling the detected face feature points by means of converting world coordinate systems, camera coordinate systems, image physical coordinate systems and image pixel coordinate systems so as to determine head poses of the drivers and judging whether the drivers are in the states of being tired or not on the basis of the fatigue states and the head poses of the drivers. The video images of the drivers are taken by a camera.

Description

technical field [0001] The disclosure belongs to the technical field of computer vision and image processing, and in particular relates to a method and device for real-time detection of a driver's state. Background technique [0002] With the development of science and technology economy, people's living standards are improving day by day, and cars have become an indispensable part of people's life, but at the same time, the number of traffic accidents is also increasing, which has caused huge losses to people's lives and property. Among them, driver's fatigue driving and inattention are the important reasons for causing traffic accidents. Fatigue is a common physiological phenomenon in daily life. It is caused by people who cannot get enough rest after working for a long time. However, traffic accidents caused by fatigue driving have caused immeasurable losses to countries all over the world every year. [0003] There are several works on driver status detection as follows...
