Title:
DRIVER FATIGUE DETECTION METHOD BASED ON MULTIPLE STRATEGIES
Document Type and Number:
WIPO Patent Application WO/2023/103206
Kind Code:
A1
Abstract:
A driver fatigue detection method based on multiple strategies. The method comprises the steps of: calibrating a target region and inputting a related threshold value; segmenting an image of the target region by using an improved DeepLabV3+ algorithm, so as to obtain contours of eyes and a mouth; calculating related values of the eyes and the mouth according to the contours, so as to determine states of the eyes and the mouth; and determining, according to an adaptive fatigue determination rule and the states of the eyes and the mouth, whether a driver is in a fatigue driving state. Rectangular fitting is performed on contours obtained by means of segmentation, so as to remove interference target information; misjudgment of closed eyes or a yawn caused by factors such as small eyes and a big mouth of a driver is effectively prevented; and by means of an adaptive fatigue determination rule, misjudgment caused by information being incomplete, insufficiently using calculation information, etc., is prevented.
