Abstract

The invention relates to the technical field of intelligent driving, and discloses a driver fatigue behavior monitoring method and device, equipment and a storage medium. The method comprises the following steps: monitoring the interference of the current action of a driver on a wireless signal to obtain channel state information; performing feature extraction on the channel state information to obtain signal features; performing dimension reduction on the signal features to obtain target features; inputting the target feature into a pre-trained target fatigue behavior recognition model to obtain a classification result output by the target fatigue behavior recognition model; and judging whether the current action of the driver is a fatigue driving action or not according to the classification result to obtain a driver fatigue behavior monitoring result. By means of the mode, the actions of the driver are monitored in combination with wireless sensing, whether the actions of the driver are fatigue driving actions or not is recognized through the trained fatigue behavior recognition model, fatigue driving monitoring is achieved, fatigue driving is reduced, and the occurrence rate of road traffic safety accidents is reduced.

Description

technical field [0001] The present invention relates to the technical field of intelligent driving, in particular to a driver fatigue behavior monitoring method, device, equipment and storage medium. Background technique [0002] At present, driver's fatigue driving is one of the most important factors causing road traffic safety accidents. When the driver is driving in a fatigued state, there will be phenomena such as shifting gears and braking not in time, severe cases will cause slow movements, forgetting to operate, etc., and even short-term sleep phenomenon will occur, and the control of the car will be lost. ability, thus causing a series of security incidents. Therefore, reducing the occurrence of fatigue driving can effectively reduce the incidence of road traffic safety accidents. [0003] At present, there are two methods for driver fatigue monitoring. The first method is to use image processing and analysis to monitor driver fatigue. Yawning and other actions a...
