Problems solved by technology

Mainly: when the locomotive driver has mastered the use of the "unmanned alert button" proficiently, the locomotive driver repeatedly taps the button mechanically, but the work is not in a state of excitement, and may even use other auxiliary simple mechanical devices to automatically Knocking, thus opportunistic, the driver can completely ignore it and lose its real effect

Embodiment Construction

[0024] This embodiment is set on a long-distance truck to detect the fatigue state of the driver of the long-distance truck. When in use, the driver's eyes are captured in real time and compared with the image of the fatigue state, and when the truck driver is driving in a fatigue state, some methods are used to remind the truck driver to drive or take a break Then continue working. In the way of self-learning in advance, the eye image of the driver when fatigued is saved in the template library as a fatigue template.

[0025] Such as figure 1 As shown, the truck driver fatigue detection device in this embodiment includes a facial image acquisition device that acquires the facial image of the detected object, and processes the facial image acquired by the facial image acquisition device to obtain a video of the eye image of the detected object. A processing device, a master controller and a storage device storing a database of fatigue templates.

[0026] The facial image ac...

Abstract

The invention provides a method and a device for detecting fatigue. By the method, whether a to-be-detected object is in fatigue or not is determined by detecting opening and closing states of eyes of the to-be-detected object. The method includes: by the device, using a self-light-source to irradiate the face of the to-be-detected object, using a black-white camera to acquire a reflecting image, intercepting an eye image, comparing the eye image with templates in a database to determine whether to-be-detected object is in fatigue or not. By the device, human eyes can be positioned accurately, closed and open eyes can be identified accurately, fatigue state is determined according to eye closing time, the reference eye closing time can be customized, human face (head) state can be determined accurately, human face direction can be determined, driver's driving states can be determined according to different human face directions, and a driver can be reminded of looking forwardly during driving.

Description

technical field [0001] The invention relates to the field of image intelligent processing and recognition, and more specifically relates to a novel fatigue detection method and device with a self-learning function. Background technique [0002] At present, my country's road transportation and railway transportation (including: subway transportation) widely implement the working mode of long-distance roads and single-driver duty. The driver's operating section is long and the work pressure is high, especially when the driver is on duty at night, the probability of driver fatigue at work increases, which is an important risk factor for road driving safety. [0003] According to the current research, the traffic control department and the railway department have adopted active management and technical measures for potential safety hazards such as poor working conditions, fatigue, and even drowsiness of drivers and passengers that may occur during operation. There are mainly two...
