In an elevator, at each of a plurality of floors, a mark having identification information corresponding to each of the plurality of floors is disposed at a position that can be visually recognized from the inside of a car when an elevator door is open and that cannot be visually recognized from the inside of the car when the elevator door is closed. The door state determination device acquires an in-car image captured by a camera mounted on a moving body capable of getting on and off an elevator, determines a door opening/closing state of an elevator door according to whether the in-car image includes a marked image, and when the in-car image includes the marked image, extracts identification information from the marked image, and determines the door opening/closing state of the elevator door. And determining the floor where the elevator door is opened according to the identification information.

    在电梯中,在多个楼层的层站中的各个层站,具有与多个楼层的层站分别对应的识别信息的标记配置于在电梯门打开的状态下能够从轿厢内视觉辨认且在电梯门关闭的状态下不能从轿厢内视觉辨认的位置。门状态判定装置取得由搭载于能够乘降电梯的移动体的摄像头拍摄到的轿厢内图像,根据在轿厢内图像中是否包含标记的图像来判定电梯门的门开闭状态,在轿厢内图像中包含标记的图像时,从标记中提取识别信息,根据识别信息判定电梯门开着的楼层。
