Abstract

The "Closing and Centering" of the miter gate of the large shiplock is one of the core control process requirements of the ship-lock operation control system. It is an important guarantee for the safe and efficient operation of the shiplock. Taking the miter gate of the Three Gorges Shiplock as the object, this paper studies the principle and method of image recognition, and adopts the methods of real-time image preprocessing, filtering and denoising, threshold segmentation, algorithm detection, Hough transform straight line fitting, system calibration and mathematical conversion to realize the real-time monitoring scheme of miter gate centering door gap. The research results are helpful to realize the real-time monitoring of the closing process of miter gate of Three Gorges Shiplock, and effectively avoid the collision and extrusion accident caused by the too large closing gap. It provides the theoretical support for the navigation benefit of the Changjiang River Junction and promoting the automatic and intelligent operation level of the Three Gorges Shiplock.
