The invention discloses a video-based elevator space occupancy ratio detection method, which comprises the following steps of: installing a monitoring camera in the middle of the top of an elevator car, covering the whole ground of the elevator car with a camera monitoring area, drawing a ground area and setting detection parameters when the elevator car is in a closed and vacant state; initial background information including brightness, chromaticity and pixel tolerance is generated according to the set parameters, one set of background information is fixed and cannot be updated in real time, meanwhile, another set of background information is generated, the initial value of the background information is consistent with that of the first set of fixed background information, then real-time updating is conducted according to environment changes, and image information is obtained in real time; and comparing the background information with the first group of fixed background information to generate a foreground image, and calculating the occupancy proportion of the car according to the foreground image information. According to the method, the elevator car monitoring camera video is utilized, elevator image analysis is carried out, the elevator car occupied space proportion is estimated, a reference basis can be provided for elevator dispatching, and the elevator use efficiency is improved.
本发明公开了一种基于视频的电梯空间占用比例检测方法,在轿厢顶部正中间安装监控摄像头,摄像头监控区域覆盖轿厢全部地面,在轿厢关闭并空置状态下绘制地面区域以及设置检测参数,然后根据设置的参数生成初始的包括亮度、色度、像素点容差度的背景信息,一组背景信息固定,不会实时更新,同时另外生成一组背景信息,初始值与第一组固定的背景信息一致,然后根据环境变化实时更新,并实时获取图像信息,再与第一组固定的背景信息比较后生成前景图像,根据前景图像信息计算轿厢的占用比例。本发明的方法,利用轿厢监控摄像头视频并通过电梯图像分析,实现对轿厢占用空间比例的估计,能够为电梯的调度提供参考依据,并提高电梯的使用效率。
