Embodiment Construction

[0018] The realization method of monitoring the car steering wheel is: paste a sign image on the car steering wheel in advance, fix the mobile phone at the position where the mobile phone camera can accurately capture the sign image on the car steering wheel, and then use the video recording function on the mobile phone to regularly collect images At the same time, image processing technology is used to analyze and recognize the current steering wheel logo image and the steering wheel logo image collected 1 minute ago. If the car is driving and the logo image does not rotate within a certain period of time, the driver may be in a state of fatigue driving. The system automatically sends out a voice prompt to warn the driver not to drive fatigued, but to concentrate immediately and look for a parking spot to rest at the same time.

[0019] The implementation method of judging the driving state is: the fatigue warning system performs recording operation in real time, the audio ret...

Abstract

The invention discloses an early warning method of a cell phone platform for car driving fatigue, which can quickly popularize the early warning for car driving fatigue and greatly improve the safety factor of car driving. The software is realized by mainly using the existing hardware of the existing smart phone through the following steps: 1. the steering wheel is monitored by combining the image recognition technology and audio analysis technology; 2. the car driving status is analyzed and the collision event is recognized by combining the audio analysis technology and acceleration control; and 3. the fatigue driving early warning is realized through the software in case of long-time operation of the steering wheel or long-time driving to remind the driver to rest. After collision, the position information is obtained and the text message is sent for help or automatic call for help. The incoming call monitoring is carried out in driving, and automatic rejection or automatic answering in the outdoor mode can be set. The method maximizes the functional integration including the call for help function when accident happens and accelerates the rescue speed after the accident while ensuring the accuracy and stability of the fatigue driving early warning function.

Description

technical field [0001] The invention relates to a system for realizing the driver's fatigue early warning function on a smart phone platform. Background technique [0002] Traffic accidents caused by fatigue driving have become a common problem all over the world, and these traffic accidents usually do not occur immediately at the initial stage of driving fatigue. Therefore, if a fatigue early warning system can be developed to detect the driver's The mental state of the man, and when he just shows signs of fatigue, he will send out an alarm, which can effectively improve the safety factor. [0003] At present, there are many products on the market in foreign countries, which can judge the driver's fatigue status by monitoring the driver's pupil and other physiological responses, driving information and other factors. Domestic research on driver safety status monitoring technology started relatively late, and related research is mainly carried out in universities and other ...
