Therefore, in the process of water outlet of the water dispenser, after the color image containing the container is acquired, the imaging area of the water surface boundary generated based on the tension formed between the container and the water can be extracted from the color image, and the second imaging area can be obtained. In the process of discharging water, the water surface in the container fluctuates due to tension, and an obvious reflective boundary is arranged at the boundary of the inner wall of the container, so that the boundary of the water surface can be obtained through image analysis. For example, the last current image in the current images of multiple frames is compared with the previous N (the specific value of N is flexibly set according to actual needs) images, so as to obtain an area with an obvious brightness difference, which is an imaging area of the current water surface boundary, i.e. the second imaging area.
