In some embodiments, acquiring the current image containing the container may include: detecting the current light intensity of the environment where the water dispenser is located; if the current light intensity is smaller than a preset intensity threshold value, controlling a preset light supplement lamp to be started; and after the light supplement lamp is turned on, acquiring a current image containing the container.
Because the quality of the current image can be affected when the light intensity of the environment is weak, in order to effectively detect the clear current image, the light intensity can be enhanced to reduce the influence on image acquisition. Specifically, an LED light source may be disposed on the water dispenser as a fill-in light, for example, as shown in fig. 5, the camera and the fill-in light (i.e., the light source in fig. 5) may be installed obliquely above the water outlet of the water dispenser, or, for example, as shown in fig. 6, the camera and the fill-in light (i.e., the light source in fig. 6) may be installed in the middle of the water receiving area of the water dispenser in parallel, near the water outlet, and in the same direction. The effect of light filling lamp is the illumination condition of reinforcing water receiving area for it is more controllable, thereby improves the quality that the camera gathered the image.
When the water dispenser is used for discharging water, the current light intensity of the environment where the water dispenser is located can be detected through the light sensor, whether the current light intensity is smaller than a preset intensity threshold value or not is judged, the preset intensity threshold value can be flexibly set according to actual needs, and under the condition that the current light intensity is larger than or equal to the preset intensity threshold value, a shooting device can be guaranteed to collect clear images. If the current light intensity is smaller than the preset intensity threshold value, the current light of the environment where the water dispenser is located is relatively weak, the preset light supplement lamp can be controlled to be turned on at the moment, and after the light supplement lamp is turned on, the current image containing the container is collected through the camera. If the current light intensity is greater than or equal to the preset intensity threshold value, the light supplement lamp does not need to be started.

The pixel difference may be a pixel of a region where a pixel value in the color image does not match a pixel value in a preset background image.
In an embodiment, the determining manner of the second imaging area is specifically as follows: the water in the container can form an adhesion effect on the inner wall of the container due to the existence of tension, so that the water optically shows optical characteristics such as abnormal refraction effect, and the optical characteristics can be captured and identified through a camera in the view of visual identification technology. 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.
In an embodiment, the first depth value may be determined in a specific manner: acquiring the depth value of each pixel point on the first imaging area from the depth image; and calculating an average depth value according to the depth value of each pixel point, and taking the average depth value as the first depth value. Similarly, the second depth value may be determined in a specific manner: acquiring the depth value of each pixel point on the second imaging area from the depth image; and calculating an average depth value according to the depth value of each pixel point, and taking the average depth value as the second depth value.
In an embodiment, the determining the distance between the water surface boundary and the container opening according to the first depth value and the second depth value is specifically: and calculating the difference value between the first depth value and the second depth value, and taking the absolute value of the difference value between the first depth value and the second depth value as the distance between the water surface boundary and the container opening.
And step S104, if the distance is smaller than or equal to the preset distance, controlling the water dispenser to stop discharging water.
If the distance between the water surface boundary and the container opening is smaller than or equal to the preset distance, the container can be determined to be filled with water, and therefore the water dispenser can be controlled to stop discharging water, and the water in the container cannot overflow.
In one embodiment, the actual height of the container can be determined from the current image, and the height of the water surface boundary in the container can be determined according to the current image; and determining the difference value between the actual height of the container and the height of the water surface boundary, determining whether the absolute value of the difference value is less than or equal to a preset threshold value, and controlling the water dispenser to stop discharging water if the absolute value of the difference value is less than or equal to the preset threshold value.
The embodiment of the application places the distance between container and the shooting device below the delivery port through the adjustment, so that the definition of the current picture of shooting device is greater than or equal to preset definition, then control the water dispenser to go out water, and at the in-process of going out water, based on the current image that contains the container that this shooting device shot obtained, confirm the distance between the surface of water border of container and the container mouth of container, and when this distance is less than preset distance, control the water dispenser and stop going out water, the condition of the water level of detection container that can be accurate, can be when the container will fill with water promptly, the control water dispenser of intelligence stops out water, prevent that the water in the container from spilling over, very big improvement user experience.
