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.
本申请公开了一种眼睑闭合检测方法、报警方法、装置、车辆、介质及设备,属于数据处理领域。该方法包括将感知模型对每帧当前图像中的人员进行感知检测到的双眼参考点的位置进行距离计算,得到每个当前眼睛宽度,并将当前眼睛宽度映射到归一化区间内,得到当前宽度归一化值;在预设时间段内,对获取到的多个当前宽度归一化值进行排序,得到宽度时序队列,并对宽度时序队列中的当前宽度归一化值进行加权计算,得到宽度时序队列的宽度平均值;对宽度平均值与宽度阈值进行对比判断,当宽度平均值小于宽度阈值时,确定人员的眼睛状态为眼睑闭合。本申请提高了人员眼睑闭合检测的准确度,减少了误报率,提升了用户体验。
