The invention relates to a method for detecting a trapped situation in an elevator car (110). The method comprises: receiving (210) an inoperable notification indicating an inoperable condition of the elevator car (110); obtaining (220) real-time image data of the interior of the elevator car (110) from at least one imaging device (120a-120n) arranged inside the elevator car (110); detecting (230) one or more human objects (140) within the elevator car (110) by performing a detection process based on the obtained real-time image data and at least one previously generated reference image; and generating (240) a signal indicating that the trapped condition is detected. Generating the at least one reference image includes: obtaining (310) random image data of an interior of the elevator car (110) from the at least one imaging device (120a-120n), wherein the random image data includes a plurality of images captured in a plurality of random reference scenes; and processing (320) the obtained random image data to generate at least one reference image (330). The invention also relates to an elevator computing unit (130), a detection system (100) and a computer program (525) for detecting a trapped condition within an elevator car (130).

    本发明涉及一种用于检测电梯轿厢(110)内的受困情况的方法。该方法包括:接收(210)指示电梯轿厢(110)的不可操作状况的不可操作通知;从布置在电梯轿厢(110)内部的至少一个成像装置(120a‑120n)获得(220)电梯轿厢(110)内部的实时图像数据;通过基于获得的实时图像数据和至少一个先前生成的参考图像执行检测过程来检测(230)电梯轿厢(110)内的一个或多个人类对象(140);以及生成(240)指示检测到受困情况的信号。生成至少一个参考图像包括:从至少一个成像装置(120a‑120n)获得(310)电梯轿厢(110)内部的随机图像数据,其中随机图像数据包括在多个随机参考场景中捕获的多个图像;以及处理(320)获得的随机图像数据以生成至少一个参考图像(330)。本发明还涉及用于检测电梯轿厢(130)内的受困情况的电梯计算单元(130)、检测系统(100)和计算机程序(525)。
