The invention relates to an elevator door state detection method based on a video image. The elevator door state detection method comprises the steps of: S1, collecting the video image containing an elevator door area through a camera arranged in an elevator; S2, setting an elevator door label area in the video image; S3, extracting a label area image when the elevator door is closed, and performing feature extraction and storage on the label area image; S4, performing image similarity comparison on the label area image stored in the step S3 and the elevator door label area image acquired in real time; and S5, if the similarity comparison result in the step S4 is higher than a set threshold value, outputting that the current elevator door is in a closed state, and if the similarity comparison result in the step S4 is lower than the set threshold value, outputting that the current elevator door is in an open state. The method provided by the invention is not interfered by external factors, and has better accuracy and stability. Meanwhile, according to the method, detection is carried out in a mode of combining a simple first algorithm and a complex second algorithm, and meanwhile, the requirements of accurate detection result and high detection speed are met.

    本发明涉及一种基于视频图像的电梯门状态检测方法,包括:S1、通过设置于电梯内的摄像机采集包含电梯门区域的视频图像;S2、在视频图像中设置电梯门标签区域;S3、在电梯门关闭时提取标签区域图像,对标签区域图像进行特征提取并存储;S4、将步骤S3存储的标签区域图像和实时采集的电梯门标签区域图像进行图像相似度比对;S5、若步骤S4中相似度比对结果高于设定阈值,则输出当前电梯门为关闭状态,若步骤S4中相似度比对结果低于设定阈值,则输出当前电梯门为开启状态。本发明的方法不会受到外界因素的干扰,准确性和稳定性更好。同时,本发明的方法,通过简单的第一算法和复杂的第二算法相结合的方式进行检测,同时满足检测结果精准、检测速度快。
