Engine oil consumption monitoring method and system based on machine vision and vehicle

The invention relates to the technical field of engine oil consumption monitoring, in particular to an engine oil consumption monitoring device and method based on machine vision and a vehicle. The method comprises the steps that a liquid level image of backflow engine oil in an engine is obtained; and according to the liquid level image, the liquid level height and the liquid level inclination angle are determined, the amount of backflow engine oil in the engine is determined according to the liquid level height and the liquid level inclination angle of the backflow engine oil in the engine, and the total remaining engine oil amount in the engine is determined by combining the rotating speed of the engine. The system comprises an image acquisition device for acquiring a liquid level image of engine oil; and the processor determines the liquid level height and the liquid level inclination angle of the engine oil according to the liquid level image, determines the amount of backflow engine oil in the engine ac
