Problems solved by technology

However, the fatigue state of the driver is not only reflected in the above-mentioned typical morphological indicators, but also in the physiological and psychological indicators. It is not accurate enough to judge that the driver’s fatigue state is no longer able to continue driving, and it will cause misjudgment of the driver’s fatigue level
The existing driving fatigue detection technology mainly has the following defects: (1) the morphological indicators based on video image acquisition are objectively restricted by background light (such as night, bridges, etc.); It is difficult to improve the sensitivity of morphological index detection; (3) The significance of basic fatigue before departure to real-time detection of vehicle fatigue is not considered

Embodiment 1

[0015] See attached picture.

[0016] The present invention is a driver's fatigue state detection device before driving, comprising a device cabinet body, a camera is installed on the cabinet body, a central control processor for processing the data collected by the camera and analyzing the data to make a judgment is arranged in the cabinet body, the data of the camera is The output end is connected with the data input end of the central control processor, and the scene test module is arranged in the cabinet body, and the scene test module is interactively connected with the central control processor; the direction control device and the touch display screen are arranged on the cabinet body; the direction control device The data output terminal is connected with the signal input terminal of the central control processor; the touch display screen is interactively connected with the central control processor; Analyze relevant patient data and make a judgment on fatigue and fatig...

Embodiment 2

[0019] The cabinet body is provided with a pulsometer for measuring the pulse rate of the subject; the data output terminal of the pulsometer is connected to the signal input terminal of the central control processor; Analyze the data related to the beating frequency and make a judgment on whether or not you are fatigued and the degree of fatigue.

[0020] The detection method includes: measuring the pulse beating frequency of the subject by the pulse meter, and transmitting the measured pulse beating frequency data to the central control processor.

[0021] All the other are with embodiment 1.

[0022] The scene test module analyzes and judges the results of the above scene tests and transmits the judgment result data to the central processing unit. fatigue level.

Abstract

The invention relates to an apparatus for detecting fatigue state of driver before driving and detection method thereof. The detection apparatus comprises a cabinet main body, a camera installed on the cabinet, a central control processer disposed in the cabinet body, a scenario test module, a pulse instrument, a direction operating apparatus and a touch display screen disposed on the cabinet. Morphological index of the measured is obtained by the camera, a plurality of psychological index of the measured such as response capability, danger sensing ability, attention are measured through the direction operation device and the touch display screen. Physical index of the measured such as pulse frequency is measured by the pulse instrument. A determination result is given based on synthetic evaluation of the three types of index, so that the determination result is more accurate and objective in comparison with that given only from morphological index, and error determination of driver's fatigue degree is prevented.

Description

technical field [0001] The invention relates to a rapid detection device and a detection method for detecting whether there is fatigue tendency in front of a vehicle based on multi-parameters of morphological indexes, physiological indexes and situational psychological reaction indexes. Background technique [0002] At present, with the rapid increase in the number of cars, driving safety has been raised to a very important position. Most of the major traffic accidents in driving are related to driving fatigue. research, and developed a related driving fatigue detection device. Chinese patent application number 200610031817.0 discloses a driver fatigue monitoring system and method based on image processing and information fusion technology. The received digital image information is calculated and processed to determine whether the driver is already in a state of fatigue by determining the proportion of the driver's eye closure time, the frequency of yawning, the law of head...
