And S101, when the fan is in an electric hair drier mode and the head of a user is positioned in the air supply range of the fan, acquiring the head image of the user through a camera.
Specifically, a fan operation instruction sent by a water heater is received, and the fan is controlled to be in an electric hair drier mode according to the fan operation instruction; the method comprises the steps of collecting an environment image of an air supply range of a fan through a camera, determining whether the head of a user is located in the air supply range of the fan or not according to the environment image, and collecting the head image of the user through the camera if the head of the user is located in the air supply range of the fan.
In one embodiment, if the head of a user is not in the air supply range of a fan, acquiring the relative position information and the relative height of the user and the fan; and adjusting the air supply range of the fan according to the relative position information and the relative height so as to enable the head of the user to be in the air supply range of the fan.
Specifically, a yaw angle of a fan head of the fan is determined according to the relative position of a user and the fan, and specifically, a mapping relation table between prestored relative position information and the yaw angle is obtained, wherein the relative position information and the yaw angle have a corresponding relation; and determining a target yaw angle of the fan head of the fan according to the relative position information and the mapping relation table, namely inquiring the mapping relation table, acquiring the yaw angle corresponding to the relative position information, and taking the acquired yaw angle as the yaw angle of the fan head of the fan.
The specific mode of determining the pitch angle of the fan head of the fan according to the relative height of the user and the fan is as follows: acquiring a mapping relation table between pre-stored user height information and a pitch angle of the fan head, wherein the user height information and the pitch angle of the fan head have a corresponding relation; and determining the pitch angle of the fan head of the fan according to the relative height information and the mapping relation table. And inquiring the mapping relation table, acquiring the pitch angle corresponding to the relative height information of the user, and taking the acquired pitch angle as the pitch angle of the fan head of the fan.
Adjusting the air supply range of the fan according to the yaw angle of the fan head of the fan until the head of the user is positioned in the air supply direction of the fan; and adjusting the blowing height of the fan according to the pitch angle of the fan head of the fan until the head of the user is positioned in the air supply range of the fan.

And inputting the head image of the user collected by the camera into a preset hair wettability recognition model, and recognizing the hair wettability to obtain the hair wettability of the user. Wherein, the preset hair moisture recognition model is a pre-trained neural network model.
Specifically, a sample hair humidity image is obtained, and the sample hair humidity image is identified according to a preset hair humidity label table to construct sample data; and carrying out iterative training on the neural network model based on the sample data until the neural network model converges, thereby obtaining the hair wettability recognition model. It is understood that the neural network model includes a convolutional neural network model, a cyclic neural network model and a cyclic convolutional neural network model, and of course, other network models may be used to train and obtain the hair wettability model, which is not specifically limited in this application.
In one embodiment, in order to improve the accuracy of the head image recognition of the user and reduce the complexity of the operation in the image processing, the head image of the user may be pre-processed after being acquired. Specifically, the preprocessing includes resizing the image to obtain a preset size image; and performing format conversion on the preset size image to obtain a preset format image. The preset size can be adjusted according to the pixels of the camera, for example, the preset size of the image has preset sizes of 640 × 480, 1024 × 768, 1600 × 1200, and the like, and the user can adjust the preset size to 1600 × 1200 according to the requirement; the preset format image can be set in advance by a user, for example, the format of the image includes TIFF format, RAW format, JPEG format, and the like, and the user can adjust the preset format to the RAW format according to the requirement.
Specifically, the size of the collected head images of the user is adjusted, so that the collected images with different sizes are adjusted to be uniform in size; after the size of the image is adjusted, format conversion is performed on the image with the preset size, wherein different formats of the acquired head image of the user may be caused due to different sampling formats of the cameras, for example, the head image may be in a RAW format or a JPEG format, and format conversion is performed on the image with the preset size by using a conversion formula to convert the image into a uniform format, for example, the image with the preset size is converted into the RAW format. It should be noted that, when performing size adjustment and format adjustment on the acquired image, the adjustment sequence of size adjustment and format adjustment is not limited, and the size adjustment and then the format adjustment may be performed first, or the format adjustment and then the size adjustment may be performed first.

In one embodiment, when the fan is in the three-gear warm air mode, images within the air supply range of the fan are collected at intervals, and if a user leaves the air supply range of the fan, the warm air gear of the fan is adjusted to the lowest gear, so that the energy consumption of the fan is reduced.
