The invention discloses an elevator door fault detection method and device and an elevator door fault occurrence rate prediction method and device. The elevator door fault detection method comprises the steps that a time sequence image of an elevator door is obtained; elevator door key point detection is conducted on the time sequence image, and a left door edge key point and a right door edge key point are obtained; calculating the distance between the left door edge key point and the right door edge key point; and judging the fault type according to the distance. And if no elevator fault is found, the fault occurrence probability of the current normal elevator door is intelligently predicted. The fault occurrence probability is calculated through the coordinates, the speed and the acceleration of the key points, the calculation method is simple, and judgment is more accurate.

    本发明公开了一种电梯门故障检测方法、电梯门故障发生率预测方法及装置,包括:获取电梯门的时间序列图像;对所述时间序列图像进行电梯门关键点检测,得到左门边缘关键点和右门边缘关键点;计算所述左门边缘关键点和右门边缘关键点之间的距离;根据所述距离判断故障类型。如果没有发现电梯故障,对当前正常电梯门故障发生概率进行智能预测。通过关键点的坐标、速度以及加速度,计算故障发生概率,计算方法简单,判断更准确。
