The invention relates to the technical field of image processing, in particular to a multi-source data fusion elevator safe operation monitoring method, which comprises the following steps: acquiring displacement sensor data, acquiring peak points of elevator door edge images at each moment in an elevator door video, acquiring all peak point pairs of the elevator door edge images at two adjacent moments, and acquiring a displacement sensor image; calculating the matching distance of the peak point pairs, obtaining the first difference of the two peak point pairs according to the matching distance, further obtaining a door slot point, obtaining the credibility of door slot detection according to the door slot point, obtaining a first displacement distance sequence, a second displacement distance sequence, a second distance sequence and a third distance sequence according to the credibility and the displacement sensor data, and obtaining the first distance sequence, the second distance sequence and the third distance sequence; and four correlation coefficients are further obtained, displacement sensor abnormity recognition is conducted according to the correlation coefficients, and elevator door opening and closing state operation detection is conducted according to data of displacement sensors without abnormity. The abnormal displacement sensor can be recognized, and the state of the elevator door can be detected more accurately.

    本发明涉及图像处理技术领域,具体涉及多源数据融合的电梯安全运行监测方法,包括:采集位移传感器数据,获取电梯门视频中每一时刻的电梯门边缘图像的峰值点,获取所有相邻两个时刻的电梯门边缘图像的所有峰值点对,计算峰值点对的匹配距离,根据匹配距离获取两个峰值点对的第一差异,进一步得到门缝点,根据门缝点获取门缝检测的可信度,根据可信度以及位移传感器数据获取第一位移距离序列、第二位移距离序列、第二距离序列以及第三距离序列,进一步得到四个相关系数,根据相关系数进行位移传感器异常识别,根据不存在异常的位移传感器的数据进行电梯门开关状态运行检测。本发明可识别异常的位移传感器,对电梯门状态的检测更加准确。
