The invention relates to a method for triggering the acquisition of image data of an empty elevator car (110). The method includes obtaining (310) door status data representative of a status of a door of the elevator car (110), obtaining (320) occupancy status data representative of an occupancy status of the elevator car (110), detecting (330) that the door of the elevator car (110) is closed based on the obtained door status data, detecting (340) that the elevator car (110) is empty based on the obtained occupancy status data, and determining (330) that the elevator car (110) is empty. And in response to detecting that the door of the elevator car (110) is closed and the elevator car (110) is empty, generating (350) a control signal to an imaging device (230) arranged inside the elevator car (110). The control signal comprises instructions for triggering acquisition of the image data of the empty elevator car (110). The invention also relates to a triggering system (200) for triggering the acquisition of image data of an air elevator car (110), and to an elevator system comprising a triggering system (200).

    本发明涉及一种用于触发获取空电梯轿厢(110)的图像数据的方法。该方法包括获得(310)表示电梯轿厢(110)的门的状态的门状态数据,获得(320)表示电梯轿厢(110)的占用状态的占用状态数据,基于所获得的门状态数据检测(330)电梯轿厢(110)的门关闭,基于所获得的占用状态数据检测(340)电梯轿厢(110)是空的,以及响应于检测到所述电梯轿厢(110)的门关闭并且所述电梯轿厢(110)是空的,向布置在所述电梯轿厢(110)内部的成像装置(230)生成(350)控制信号。所述控制信号包括用于触发对所述空电梯轿厢(110)的所述图像数据的采集的指令。本发明还涉及一种用于触发对空电梯轿厢(110)的图像数据的采集的触发系统(200),以及涉及一种包括触发系统(200)的电梯系统。
