Abstract

The invention discloses a driver fatigue state facial feature recognition and detection method, and relates to the technical field of driver fatigue early warning. The method comprises the steps of S01, acquiring a real-time monitoring video of a driver, and recognizing a face in the detection video; S02, positioning human eyes in the human face area; and S03, identifying the human eye state, determining the human eye state, comprehensively judging the fatigue degree according to the human eye state, and sending out corresponding alarm information according to the fatigue degree. The method issuitable for complex and variable cab illumination conditions and high-frequency low-amplitude vibration environments during operation, the recognition accuracy is improved, and driver fatigue detection is accurately and effectively carried out.

Description

Technical field: [0001] The invention relates to the technical field of driver fatigue early warning, in particular to a method for recognizing and detecting facial features in a driver's fatigue state. Background technique: [0002] Driving fatigue refers to the decrease in the driver's response ability due to lack of sleep or long-term continuous driving. Investigations on the causes of traffic accidents have found that 85% of accidents are related to drivers, while vehicle and environmental factors account for only 15%. The driver's behaviors and failures in the moment before the accident directly lead to the accident, these behaviors include the delay of perception, wrong decision-making on the environment, improper handling of dangerous situations, etc. Among all driver errors, the most common ones are perception delays and decision errors, which can lead to inattention, slow response, improper operation, etc. The root cause of these errors is driving fatigue.
