And S101, acquiring an image of a container placed below a water outlet of the water dispenser to obtain a target image.
The type of the container can be flexibly set according to actual needs, and the container is a water cup such as a plastic cup, a ceramic cup, a glass cup or a vacuum cup.
In an embodiment, a camera may be preset around the water outlet of the water dispenser for collecting an image of a container below the water outlet of the water dispenser, wherein the camera may be an infrared camera or other types of cameras, and the specific position where the camera is installed may be flexibly set according to actual needs, for example, the camera may be installed obliquely above the water outlet or near the water outlet, so that the camera may accurately collect an image of a preset area below the water outlet of the water dispenser.
In one embodiment, when no object such as a container is placed below the water outlet of the water dispenser, the image (i.e., the image) collected by the camera is generally fixed, so that when the container for receiving water is not placed below the water outlet of the water dispenser, the image below the water outlet of the water dispenser is collected by the camera preset in the water dispenser to obtain a background image, wherein the background image does not contain the container. As shown in fig. 2, the camera 20 is located around the water outlet 10, and no container is placed below the water outlet 10 of the water dispenser.
When objects such as a container and the like are placed in a water receiving area below the water outlet of the water dispenser, the picture of the area where the container is located is obviously different from the background image, so that the collected image and the background image can be subjected to pixel comparison at the moment, and if the collected image and the background image have pixel difference, the container is determined to be placed below the water outlet of the water dispenser. Whether a container is placed below the water outlet of the water dispenser can be accurately determined through the background image and the current image below the water outlet.
In one embodiment, a pressure sensor is arranged in a water receiving area below a water outlet of the water dispenser, pressure values of the pressure sensor are obtained at intervals of preset time, if the pressure value is larger than a preset pressure value, the water receiving area below the water outlet of the water dispenser can be determined to be placed in a container, and if the pressure value is smaller than or equal to the preset pressure value, the container is not placed in the water receiving area below the water outlet of the water dispenser. As shown in fig. 3, the container for receiving water is placed below the water outlet 10 of the water dispenser.

The preset similarity may be set according to actual conditions, for example, the preset similarity is 98% or 99%.
The container image library and the volume corresponding to each container image in the container image library are stored in a cloud end or a memory of the water dispenser in advance, different containers are placed below a water outlet by a manufacturer or a user of the water dispenser, the images of the containers placed below the water outlet are shot by a camera, the water outlet of the water dispenser is manually controlled, then when the containers are full of water, the water outlet amount of the water dispenser is recorded, the volume of the containers is obtained, the container images are obtained by cutting from the shot images, the relationship between the container images and the volume is established, and the volume corresponding to each container image in the container image library are obtained.
And S103, controlling the water outlet of the water dispenser according to the volume, and controlling the water dispenser to stop water outlet when the ratio of the water outlet quantity of the water dispenser to the volume is within a preset range.
Specifically, after the volume of a container placed below the water outlet is determined, the water outlet of the water dispenser can be controlled according to the volume, namely the water outlet of the water dispenser is controlled to be opened; in the water outlet process, the current water outlet quantity of the water dispenser is obtained through a flowmeter; and determining the ratio of the current water yield to the volume, determining whether the ratio is within a preset ratio range, if so, controlling the water dispenser to stop water outlet, namely, controlling the water outlet of the water dispenser to be closed, and if not, continuing to control the water outlet of the water dispenser. The preset ratio range can be set according to actual needs, for example, the preset ratio range is 0.8-0.95, 0.85-1, or 0.8-1.
Illustratively, the preset ratio range is 0.8-0.95, the volume of the container is 1 liter, and the current water yield of the water dispenser is 0.75 liter, then the ratio of the current water yield to the volume of the water dispenser can be determined to be 0.75, if 0.75 is not within the preset ratio range of 0.8-0.95, the water dispenser is continuously controlled to discharge water, the current water yield of the water dispenser is increased, and if the current water yield of the water dispenser is increased to 0.82 liter, then the ratio of the current water yield to the volume of the water dispenser can be determined to be 0.82, and if 0,82 is within the preset ratio range of 0.8-0.95, the water dispenser is controlled to stop discharging water.
In one embodiment, when the ratio of the water outlet quantity of the water dispenser to the volume of the container is greater than or equal to a preset ratio, the water dispenser is controlled to stop water outlet. The preset ratio can be set according to actual needs, for example, the preset ratio is 0.8, 0.85, or 0.9.
