Embodiment Construction

[0020] Such as figure 1 shown. A lighting adaptive fatigue driving detection system, including a DSP main control board, a video acquisition circuit board, and a CCD camera, the output end of the CCD camera is connected to the input end of the video acquisition circuit board, and the output end of the video acquisition circuit board is connected to the DSP main control board input, where:

[0021] The video acquisition circuit board is integrated with an asynchronous serial communication interface circuit, a video acquisition circuit, and a power supply circuit. The power supply circuit supplies power to the asynchronous serial communication interface circuit and the video acquisition circuit respectively. The output end is connected with the input end of the DSP main control board through an asynchronous serial communication interface circuit;

[0022] The DSP main control board is constructed by the DSP, and the DSP is also connected with a memory expansion circuit, a netw...

Abstract

The invention discloses a lighting adaptive fatigue driving detection system and a detection method thereof. The system comprises a DSP main control board, a video acquisition circuit board and a CCD camera. Firstly a DSP controls the CCD camera to shoot an original image of a driver, after the DSP main control board receives the collected original image, a fatigue detection algorithm is started, the judgment of lighting intensity is carried out according to the characteristic that the clustering feature of skin color is influenced by lighting bright and dark conditions, the DSP main control board adaptively selects the corresponding treatment measure to complete the positioning of eye areas, then the eye positions are accurately positioned, and finally a PERCLOS value is calculated by using the relative distances of upper and lower eyelids to judge whether the driver is fatigue or not. According to the system and the method, the fatigue driving detection can be effectively carried out in a harsh light condition.

Description

technical field [0001] The invention relates to the field of fatigue driving detection systems, in particular to an illumination adaptive fatigue driving detection system and a detection method. Background technique [0002] According to the report of the Ministry of Communications, my country's traffic accidents caused by fatigue driving are the highest in the world in both absolute numbers and proportions. The conclusion drawn from the analysis of a large number of cases of traffic accidents over the years in our country is that the road traffic accidents caused by driver fatigue driving account for about 10% to 15% of the total. Especially in recent years, the rate of serious traffic accidents due to fatigue driving has a rising trend. According to Xinhuanet, fatigue driving has become the No. 1 killer on highways. [0003] In the current situation where most drivers lack awareness of the hazards of fatigue driving, it is very difficult and unrealistic to solve the prob...
