The invention discloses a method, system and equipment for automatically detecting foreign matters on a metro platform screen door, and the method comprises the following steps: S1, closing the metro platform screen door, starting an infrared light curtain, and obtaining the state data of the infrared light curtain by a control unit; s2, in the infrared light curtain correlation process, when an abnormal state occurs, a control unit obtains camera video data before and after the abnormal state of the infrared light curtain; s3, dividing the video frame by frame, and performing frame difference operation with the template image frame by frame; s4, comparing a difference result with a threshold value, and reasoning by using a foreign matter model to obtain a foreign matter type; and S5, displaying a detected foreign matter type discrimination result and an image, and performing manual checking. When the shielding door is closed, the infrared light curtains at the two ends of the shielding door are opposite to judge whether foreign matters exist between the shielding doors or not, the types of the foreign matters are judged through visual recognition of the camera at the top of the shielding door, and the state and the judgment result are sent to the server through the control unit for personnel to judge and operate. And the detection means is reliable, the human input is low, and the risk of clamping people and objects is reduced.
本发明的一种地铁屏蔽门异物自动检测方法、系统及设备,其方法分别包括:S1:地铁屏蔽门关闭,启动红外光幕,控制单元获取红外光幕状态数据;S2:在红外光幕对射过程中,出现异常状态,控制单元获取红外光幕异常状态前后相机视频数据;S3:逐帧划分视频,逐帧与模板图像进行帧差分运算;S4:比较差分结果与阈值,利用异物模型推理,获取异物类型;S5:显示检测出的异物类型判别结果及图像,并人工核查。本发明利用在屏蔽门关闭时,屏蔽门两端红外光幕对射,判别屏蔽门间是否有异物,通过屏蔽门顶部相机视觉识别,从而判别异物种类,并将状态和判断结果通过控制单元发送至服务器供人员判断及操作,检测手段可靠、人力投入少、减少了夹人、夹物风险。
