Fatigue driving identification system and identification method thereof

Abstract

The invention provides a fatigue driving identification system and an identification method thereof, and the system mainly comprises an optical identification module and a monitoring module which are assembled through a vehicle, and the optical identification module comprises an image capturing unit, an image receiving unit, an estimation operation processing unit, a transmission unit and a power supply unit, the image capturing unit emits a laser beam or an LED light beam on the face of an object to be detected and acquires face image information, the wavelength of the laser beam is between 940 nm and 1400 nm, the transmission unit transmits eye identification and head position information to the monitoring module, and the optical identification module carries out flying distance measurement identification steps and procedures on the face of the object to be detected; therefore, when a driver feels tired or dozes, the driver can be informed in real time, and traffic accidents are avoided when the driver feels tired.

Description

technical field [0001] The invention relates to an identification system, in particular to a fatigue driving identification system and an identification method thereof. Background technique [0002] According to the current 20% of traffic accidents and as many as one quarter of the fatal major traffic accidents are caused by the driver's physical fatigue, illness, fever, or drunk driving, so preventing fatigue driving, sick driving, and drunk driving is important for reducing traffic accidents and protecting The personal safety of the driver is of great significance. For fatigue driving, the current detection methods are mainly divided into subjective evaluation and objective evaluation. [0003] Subjective evaluation is through the driver's self-evaluation or other people's evaluation of the driver. Obviously, this method is greatly affected by the prediction of human factors, and the evaluation standards are inconsistent, so objective evaluation is required. Studies have...

[0004] However, the former traditional ECG detection method of human skin contact is not suitable for the application of drivers; while the latter non-contact detection method is as follows: design a detection device, the capacitive electrodes of the detection device are made of double panels, placed On the driver's seat, it is used as a signal electrode: the ground electrode is made of thick copper skin, installed on the outer edge of the left half circle of the steering wheel, connected to the analog ground in the circuit, and directly contacts the driver's left hand during driving In this way, the electrode configuration detection method is formed. When the driver wears ordinary clothes and drives normally, the ECG signal is transmitted to the subsequent amplifier circuit through the coupling effect of the capacitive electrode, and through the analog-to-digital converter (Analog-to-digital converter, ADC), Capturing digital ECG signals to the host computer for detection can help reduce the interference caused by the movement of the driver's upper body, but this non-contact method is theoretically feasible, but the practical application is not enough; use PCB to make capacitive signal electrodes, It is not easy to withstand the collision impact of the driver sitting in the driver's seat and the car body during driving, and the ground electrode still needs to be touched by the left hand, which is not a real non-contact detection
