Problems solved by technology

[0004] Due to the complexity of the implementation method of the existing fatigue detection technology, the amount of calculation is very large. It can only process about 20 frames of face images per second. When blinking, it only takes 1 to 2 frames under normal conditions, and only 3 frames under fatigue conditions. When it reaches 4 frames, it is difficult to accurately detect the blinking process, so misjudgment or missed judgment may occur
And the currently available fatigue driving monitoring and early warning devices are difficult to popularize due to the high cost

Embodiment Construction

[0015] The present invention will be described in detail below with reference to the drawings and specific embodiments.

[0016] Such as figure 1 As shown, this embodiment provides a safe driving early warning system. The safe driving early warning system is applied to the safe driving of a car, can monitor the car driver in real time, and give a timely warning when the driver is tired, distracted, or distracted. , Reduce driving safety accidents.

[0017] Among them, such as figure 1 As shown, the safe driving early warning system includes a collection unit, a processing unit, and an alarm unit connected in sequence. The collection unit is provided with an infrared camera, and the driver’s facial image information is obtained in real time through the infrared camera. For example, it can be obtained through the infrared camera. The image information of the first frame of the driver’s face and the image information of one or more secondary frames, wherein the image information of th...

Abstract

The invention discloses an early warning system and a method for safe driving. The system comprises a collecting unit, a processing unit and a warning unit which are sequentially connected, wherein the collecting unit is provided with an infrared camera used for acquiring real-time image information of a driver's face; the processing unit is provided with an image enhancement processing module for performing enhancement processing on the image information, a search module for searching in the image information to obtain image information of a face iris region and a nostril region of the driver, a calculating module for obtaining the current iris area and the sight direction of the driver through calculation and an early warning signal generating module for generating early warning signals through a preset mode according to the iris area and the sight direction obtained through the calculation. The early warning method for safe driving corresponds to the early warning system. According to the system and the method, real-time monitoring and timely warning can be performed on fatigue and distraction of the driver, driving security accidents can be reduced, the processing speed is high, the warning is accurate, and the production cost is low.

Description

Technical field [0001] The present invention relates to the technical field of safe driving of vehicles, in particular to a safe driving early warning method. Background technique [0002] Most of the institutions that studied driving fatigue used PERCLOS80 (the time it takes when the eyelid covers 80% of the pupil area and the percentage of the specific time) as a measure of physiological fatigue. Under normal circumstances, the time from opening to closing of eyes is between 0.05 and 0.1 seconds. If it exceeds 0.2 seconds, traffic accidents are prone to occur while driving. [0003] The existing non-contact fatigue driving alarm system generally installs an infrared camera in front of the driver's seat of the car, which is mainly aimed at the eyes of the driver to monitor the driver's blinking activity. If the driver is dozing off, the eyelid blinking will slow down, and the alarm system will emit a sharp warning sound to wake the driver from the doze. [0004] Due to the complex...
