Title:
FATIGUE DRIVING WARNING METHOD AND TERMINAL
Document Type and Number:
WIPO Patent Application WO/2019/056259
Kind Code:
A1
Abstract:
Provided are a method and a terminal for fatigue driving warning. The method of fatigue driving warning is applied to the terminal, and the terminal is provided with a camera. The method comprises: determining a fatigue threshold reduction component on the basis of a continuous traveling time, the current date, and the current time, and determining a real-time fatigue threshold according to an initial fatigue threshold and the fatigue threshold reduction component (S110); obtaining a driver's head drooping frequency and the driver's eye state information according to a video obtained from a camera (S120); obtaining a fatigue value of the driver according to the head drooping frequency and the eye state information (S130); and when it is determined that the fatigue value is greater than or equal to the real-time fatigue threshold, making an alert to the driver (S140). The method and the terminal determine a real-time fatigue threshold according to the continuous driving time, the current date, and the current time. Thus, the real-time fatigue threshold is used as a criterion for determining the degree of fatigue of the driver, thereby reducing the computational complexity of fatigue driving determination and improving the warning accuracy of fatigue driving.
