Method, device and equipment for identifying sand content of colorless liquid and storage medium

The invention provides a method, device and equipment for identifying the sand content of colorless liquid and a storage medium, and belongs to the field of sand content detection.The method comprises the steps that a sand sample in seawater is collected; sequentially adding the sand samples into pure water according to a preset unit weight, and carrying out image acquisition after the sand samples are added each time, so as to obtain a sand content gradient image; calculating the sand content according to the amount of the pure water and the weight of the added sand sample after the sand sample is added every time, and mapping the sand content and the grayed sand content gradient image to form a mapping relation; and identifying the sand content corresponding to the obtained seawater image according to the mapping relation. According to the method, the water sample image is processed and analyzed, the characteristic that sand components are stable is utilized, the relation between the sand content and the wa
