Abstract

The invention discloses an eyelid closing detection method and device, an alarm method and device, a vehicle, a medium and equipment, and belongs to the field of data processing. The method comprises the following steps: performing distance calculation on the positions of two eye reference points detected by a perception model for perceiving a person in each frame of current image to obtain the width of each current eye, and mapping the width of each current eye to a normalization interval to obtain a current width normalization value; in a preset time period, sorting the obtained current width normalization values to obtain a width time sequence queue, and performing weighted calculation on the current width normalization values in the width time sequence queue to obtain a width average value of the width time sequence queue; and comparing and judging the width average value with a width threshold value, and when the width average value is smaller than the width threshold value, determining that the eye state of the person is eyelid closing. According to the invention, the accuracy of person eyelid closure detection is improved, the false alarm rate is reduced, and the user experience is improved.

Description

technical field [0001] The present application relates to the field of data processing, and in particular, to an eyelid closure detection method, an alarm method, a device, a vehicle, a medium and a device. Background technique [0002] The detection of the closed state of the human eyelid is more and more widely used in all walks of life. For example, the eyelid closure detection for drivers is mainly used to detect the driver's fatigue driving; the eyelid closure detection for online class students is mainly used to detect whether the students are drowsy during the class; the eyelid closure detection for salespersons is mainly used for To detect if the salesperson dozed off during work, etc. [0003] However, due to the different sizes of eyes of different people and the different opening distances of the eyes, under the same criterion, the detection results of the eyelids of people with small eyes are often inaccurate. SUMMARY OF THE INVENTION [0004] In order to sol...
