description The invention relates to a driver fatigue detection method based on facial action unit recognition. The method includes the steps of 1, locating a facial area in a video sequence; 2, locating and zoning facial key feature points; 3, subjecting corresponding facial areas in multiple frame images to movement feature extraction; 4, classifying and recognizing extracted movement features, and using an AU (action unit) to mark out; 5, detecting whether a driver is fatigue or not by the facial action unit. The method has the advantages that facial appearance features in the fatigue state are extracted according to facial appearance states so that more stable and rich visual information can be obtained; the method is convenient and practical.
