Summary:The invention discloses a method for monitoring the lubrication state of a large open gear of a ship lock hoist. The method comprises the steps that when the gear runs, adopting an infrared thermal imaging camera for obtaining an RGB image and a thermal image of the gear surface; segmenting the tooth surface RGB image and the thermal image to obtain a complete and single pure tooth surface RGB image and a pure tooth surface thermal image; for the pure tooth surface RGB image, adopting a preset algorithm to screen out a suspected oil shortage area; analyzing the pure tooth surface thermogram toobtain characteristic data; according to the thermogram feature data corresponding to the suspected oil starvation area, judging the oil starvation degree of the related area according to preset logic judgment steps; and obtaining an oil shortage area position and an oil shortage degree grade, and taking corresponding measures. The tooth surface lubricating effect can be monitored in real time, the tooth surface lubricat
