The invention belongs to the technical field of elevators, discloses an elevator door recognition method and device, and aims at solving the problems that an existing elevator door area position recognition method is poor in accuracy and large in human resource consumption. Background modeling is adopted for motion extraction, an image mask corresponding to the monitoring image is obtained, and the image mask is used for representing the pixel change position in the monitoring image; carrying out contour extraction on the image mask to obtain at least one contour and a corresponding contour size parameter; screening out contours meeting requirements according to the contour dimension parameters; and the door area position of the elevator is determined according to the screened outline. According to the invention, the accuracy and universality of door area position identification of the elevator are improved, the consumption of human resources is reduced, and the method is particularly suitable for detecting the opening/closing state of the elevator door.

    本发明电梯技术领域,公开了一种电梯门的识别方法及装置,旨在解决现有的电梯的门区位置识别方法存在准确性较差以及人力资源消耗大的问题,方案主要包括:获取电梯的监控图像;采用背景建模进行运动提取,获得所述监控图像对应的图像掩膜,所述图像掩膜用于表示监控图像中的像素变化位置;对所述图像掩膜进行轮廓提取,获得至少一个轮廓及其对应的轮廓尺寸参数;根据所述轮廓尺寸参数筛选出满足要求的轮廓;根据筛选出的轮廓确定电梯的门区位置。本发明提高了电梯的门区位置识别的准确性和通用性,并且降低了人力资源消耗,特别适用于电梯门的开关状态检测。
