The invention relates to the technical field of posture recognition, in particular to an early warning method and system for falling in an elevator, and the method comprises the steps: collecting an image in the elevator through a depth camera, extracting a first key image and a reference image, and extracting key points from the first key image, whether an abnormal human body posture exists or not is obtained according to the key points and the reference image, a falling-down abnormal signal is sent out for the abnormal human body posture, and an alarm is given after the falling-down abnormal signal is obtained. According to the method, the steps of target identification are simplified, and the abnormal signals are obtained at the positions of the target at different moments through height identification of the target, so that the identification is more efficient, the response is faster, and the processing pressure is reduced.

    本发明涉及姿态识别技术领域,具体涉及一种电梯内跌倒预警的方法及系统,所述方法包括:使用深度相机采集电梯内的影像提取第一关键图像和参考图像,从第一关键图像中提取关键点,根据关键点和所述参考图像得到是否存在异常人体姿态并对异常人体姿态发出跌倒异常信号,得到跌倒异常信号后进行报警。本发明实现了简化了目标识别的步骤,通过对目标的高度识别,在不同时刻目标的位置得到异常信号,使得识别更高效,反应更快,减轻了处理压力。
