specific Embodiment approach

[0037] detailed description: Below in conjunction with accompanying drawing, the present invention will be further described:

[0038] The invention provides a multi-modal driver fatigue detection method It is characterized in that: the specific steps of the method are as follows:

[0039] The first step: dual-channel image acquisition;

[0040] (1) Channel 1 is a wide-angle camera with a fixed position and direction. The wide-angle camera collects a complete image in the cab, establishes a three-dimensional coordinate system in space, and combines the background prior knowledge in the collected images to perform face detection and judge the driver's head. The three-dimensional coordinate information of the head in space;

[0041] (2) Channel 2 is a high-resolution camera whose position and angle can be moved three-dimensionally. According to the head coordinate information obtained by channel 1, it is transmitted to channel 2, so as to locate the shooting angle of the c...

Abstract

The invention provides a multimodal driver fatigue detection method and special equipment thereof. The special equipment comprises a dual-channel vision detection device, a multipoint pressure detection device and a physiological signal real-time detection device which are used for detecting the motion trails of heads, forms of human eyes and mouths, multipoint pressure change curves and pulses, so that information is subjected to multimodal fusion to form a set of multi-characteristic fatigue evaluation scheme; and the accuracy of fatigue detection is increased by multiple fatigue characteristics under the condition that the normal operation of drivers is not interfered. The system design gives priority to practicability, operability and humanization, and the stability and safety and reliability of the system is ensured. The method is reasonable, simple in device, accurate in detection and high in operability, and is favorable for popularization and application.

Description

technical field [0001] The present invention relates to a driver fatigue detection method and its special equipment, in particular to a multi-modal driver fatigue detection method and its special equipment. Background technique [0002] Fatigue driving is an important factor that causes traffic accidents. If the driver's fatigue state can be automatically detected and alarmed in time, the occurrence of traffic accidents will be effectively reduced. Existing fatigue detection methods have problems such as single detection and evaluation methods and complex actual working environment, which are difficult to meet the needs of practical applications. As important means of transportation, trains and long-distance transport vehicles have large transport volumes, long working hours for drivers, are prone to drowsiness, and easily lead to traffic accidents. At present, there is no practical driver fatigue detection and alarm device in China. Contents of the invention [0003] P...
