Elevator anti-pinch method and system based on image processing

The invention discloses an elevator anti-pinch method and system based on image processing. According to the key point of the technical scheme, the method comprises the following steps that video dataof a door seam of an elevator door is acquired; whether a foreign matter exists in the current frame elevator door image or not is determined through an image comparison mode based on each frame elevator door image in the video data; and the elevator door is controlled to stop closing or open when the foreign matter exists in the current frame elevator door image. According to the method and system, the video data of the door seam of the elevator door is acquired, the video data is analyzed, whether the foreign matter exists in the door seam of the elevator door or not is judged by using theimage comparison technology, so that compared with an infrared detection mode, the method can detect a much tinier object and has the characteristics of high detection precision and high detection sensitivity. 本发明公开了一种基于图像处理的电
