Embodiment Construction

[0037] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0038] A driver anti-fatigue early warning method, such as figure 1 and figure 2 shown, including the following steps:

[0039] S1. Obtain the driver's heart rate data and blink frequency data;

[0040] S101. Obtain the driver's heart rate data and facial image data;

[0041] S102. Process the facial image data to obtain the blink frequency.

[0042] Specifically, the eyes are monitored and tracked in real time by camera technology, the characteristic parameters of the eyes are analyzed and extracted, and the blink frequency is obtained.

[0043] S2. Display the driver's current heart rate data and blink frequency data, and preset the heart rate data and blink frequency range corresponding to the driver's fatigue state;

[0044] S3. Comparing the driver's heart rate data and eye blink frequency data with the preset heart rate data and e...

Abstract

The invention discloses a driver fatigue prevention early warning method, a driver fatigue prevention early warning system and terminal equipment. The method comprises the following steps: acquiring the heart rate data and the blink frequency of a driver; displaying the current heart rate data and blink frequency data of the driver, and presetting heart rate data and blink frequency ranges corresponding to the fatigue state of the driver; comparing the heart rate data and the blink frequency data of the driver with the preset heart rate data and blink frequency ranges, and judging whether thedriver is in a fatigue state or not; and if the driver is in the fatigue state, sending a warning signal. Through comprehensive comparison and analysis of the heart rate and the blinking frequency, whether the driver is in the fatigue state or not can be directly and quickly judged, the driver is reminded, and traffic accidents are effectively reduced.

Description

technical field [0001] The invention belongs to the technical field of monitoring and early warning methods, and relates to a driver anti-fatigue early warning method, a driver anti-fatigue early warning system, and a driver anti-fatigue early warning terminal device. Background technique [0002] In daily traffic, the proportion of automobiles is getting higher and higher. Although automobiles can greatly improve people's quality of life, the safety driving problems brought about by the popularization of automobiles have become a problem that people must not ignore. When a driver is fatigued, his ability to observe, recognize and control the vehicle will be significantly reduced, seriously threatening his own safety and the lives of others. For most people, they still rely on subjective thoughts and consciousness to judge emergencies in the driving process. With the frequent occurrence of safety accidents, the safety concept has attracted people's attention. [0003] Exis...
