Embodiment Construction

[0102] The driver fatigue state detection system includes video DSP, camera, data storage circuit, program memory, clock chip, keyboard and voice chip. The system uses the camera to collect the driver's face image in real time. Under the scheduling of the video DSP processor, the image data is analyzed and processed by the algorithm processor to judge in real time whether the driver is distracted or dozing off. In the state of fatigue driving, immediately notify the driver and relevant departments to deal with it through sound alarm and GPRS sending information.

[0103] According to the circuit function structure, the system can be divided into three main functional modules: image acquisition and storage module, image processing module and human-computer interaction interface module.

[0104] 1. Image acquisition and storage module

[0105] The image acquisition is mainly composed of camera, data storage circuit, I2C controller and video DSP. At the same time, in order to i...

Abstract

The invention discloses a method for detecting a fatigue state of a driver based on a digital video. The method comprises the following steps: firstly detection and positioning of a human face are carried out based on images acquired by a camera; after the human face is positioned, the eye area and the mouth area are searched; and based on the found eye area and mouth area, the eye condition and the mouth condition are judged so as to judge whether the driver is in the fatigue driving state or not. In the invention, the high-precision face detection algorithm and the highly reliable fatigue detection algorithm are adopted, so that the function of the high-precision and highly reliable fatigue state detection can be realized.

Description

technical field [0001] The invention relates to a driver fatigue detection and alarm device, which belongs to a traffic safety protection alarm device. The device has the functions of sound and light warning and forced parking for fatigue driving. Background technique [0002] Safe driving depends on many factors. In addition to natural factors such as vehicle conditions and road conditions, the driver's human factors play a decisive role. A large number of analysis and research have shown that driver fatigue driving is one of the main causes of traffic accidents, especially in Nearly half of all traffic fatalities on highways are due to fatigued driving. [0003] Some foreign automobile manufacturers and research institutions have invested huge manpower and material resources to carry out extensive research on driver fatigue detection, and some research has been transformed into corresponding products. For example, VOLVO Motor Corporation has launched a "driver warning sy...
