The embodiment of the application provides a fan control method, which realizes that a fan is controlled when a user is in a sleep state so that the current temperature is suitable for the current state of the user by means of thermal imaging images including the user, and improves convenience and flexibility of fan control.
The following describes in detail the steps of implementing the fan control step by step in the embodiment of the present application:
step S101, obtaining current human body sign data of at least one user, and analyzing the human body sign data to judge whether the user is in a sleep state currently.
Illustratively, the fan is communicatively coupled to a wearable device of the user. The wearable device obtains the current human body sign data of the user and sends the human body sign data to the fan. And the fan receives the current human body sign data of the user, analyzes the current human body sign data of the user and determines whether the user enters a sleep state currently.
In some embodiments, the obtaining current human body sign data of at least one user and analyzing the human body sign data to determine whether the user is currently in a sleep state specifically includes the following steps:
receiving a user heart rate sent by the wearable device, and analyzing the user heart rate to judge whether the user is in a sleep state currently.
Specifically, the heart rate of a person in a sleeping state is greatly different from that of the person in a waking state, so that whether the user enters the sleeping state currently can be judged according to the heart rate of the user. Illustratively, the heart rate at rest for normal persons is about 60-80 times/min for men and about 70-90 times/min for women; the heart rate is reduced when the patient is asleep, with 50-70 times/min for men and 60-70 times/min for women. Therefore, when the user is a male, the heart rate is reduced from the interval of 60-80 times/min to the interval of 50-70 times/min and is stabilized at the interval of 50-70 times/min, the user can be determined to be in the sleep state currently; when the user is female, the heart rate is reduced from the interval of 70-90 times/min to the interval of 60-70 times/min, and is stabilized in the interval of 60-70 times/min, the user can be determined to be in the sleep state currently.
And step S102, if the user is determined to be in the sleep state currently, calling the shooting module to acquire a thermal imaging image containing the user.
When a user enters a sleep state, the fan cannot be regulated and controlled in time according to the requirement of the user, so that the situations of over-strong air supply or insufficient air supply of the fan and the like easily occur. In some embodiments, the fan is provided with a camera module for taking a thermographic image, which may include a thermographic camera, but may also include other devices or systems capable of taking a thermographic image. And when the user is judged to be in the sleep state currently, the shooting module is called regularly according to a preset time interval so as to acquire the thermal imaging image containing the user.
Step S103, determining the current body temperature data of the user according to the color corresponding to the target image area in the thermal imaging image based on the corresponding relation between the color and the temperature of the thermal imaging image.
The different colors on the thermographic image represent the different temperatures of the object under test. In this embodiment, the target image area in the thermal imaging image corresponds to an area where the user is located, so that the current body temperature data corresponding to the user can be determined according to the color corresponding to the target image area in the thermal imaging image.
In some embodiments, before determining the current body temperature data of the user according to the color corresponding to the target image region in the thermal imaging image, the method further includes: a target image region in the thermographic image is determined.
Illustratively, the determining the target image area in the thermal imaging image specifically includes the following steps:
a1, extracting human body contour information of a user in the thermal imaging image;
and A2, determining a target image area where the user is located in the thermal imaging image according to the human body contour information.
Illustratively, the step of extracting the human body contour information of the user in the thermal imaging image comprises: determining a pseudo color interval corresponding to the temperature range of the human body according to the corresponding relation between the preset temperature range and the pseudo color interval; determining an image of a false color in the thermal imaging image in a false color interval corresponding to the temperature range of the human body as a thermal imaging person image of the user; and extracting the human body outline information of the user according to the thermal imaging person image of the user.
Specifically, the corresponding relationship between the temperature range and the pseudo color interval may be preset, where the corresponding relationship may be that one temperature value corresponds to one pseudo color, and one temperature range corresponds to one pseudo color interval, for example: and the temperature range of 36 ℃ corresponds to dark red, the temperature range of 37 ℃ corresponds to red, the temperature range of 38 ℃ corresponds to dark red, and the like, so that the false color interval corresponding to the temperature range of the human body can be determined to be dark red to dark red according to the corresponding relation between the preset temperature range and the false color interval. And then determining the image of the false color in the thermal imaging image in the false color interval corresponding to the temperature range of the human body as the thermal imaging person image of the user, namely determining the image of the false color in the thermal imaging image in the false color interval from dark red to dark red as the thermal imaging image of the user.
After the thermal imaging character image of the user is determined, determining the position information of the thermal imaging character image, and determining the coordinate value of the edge pixel point of the thermal imaging character image from the position information of the thermal imaging character image; obtaining human body contour information of the thermal imaging character image according to the coordinate values of the edge pixel points, namely the human body contour information of a user; and finally, determining a target image area where the user is located in the thermal imaging image according to the human body contour information.
In the embodiment of the invention, the pseudo color interval corresponding to the temperature range of the human body can be determined by acquiring the corresponding relation between the pre-defined temperature range and the preset temperature range and the pseudo color interval, and further the position information of the thermal imaging person image in the thermal imaging image is determined; extracting human body contour information of the thermal imaging figure image, namely human body contour information of a user according to the position information of the thermal imaging figure image; and determining a target image area where the user is located in the thermal imaging image according to the human body contour information, and finally determining the current body temperature data of the user according to the target image area, so that the interference caused by the ambient temperature is avoided, and the error of fan control is reduced.
In some embodiments, the determining the current body temperature data of the user according to the color corresponding to the target image area in the thermal imaging image specifically includes: step S1031 to step S1033.
Step S1031, based on a preset picture division rule, dividing the target image region into a plurality of pixel blocks, where each pixel block includes at least one pixel point.
For example, in order to increase the reading rate of the thermal imaging image information, that is, the reading rate of the target image area information, a block reading method is adopted, that is, the target image area is divided into a plurality of pixel blocks according to a preset picture division rule, wherein the pixel blocks include at least one pixel.
Step S1032 determines temperature data corresponding to each of the pixel blocks according to the color of each of the pixel blocks based on a correspondence between the color and the temperature of the thermal imaging image.
Exemplarily, firstly, a mapping relation table between preset thermal imaging image colors and temperatures is obtained, and a corresponding relation between the thermal imaging image colors and the temperatures is obtained; and then determining temperature data corresponding to each pixel block in the target image area according to the color of each pixel block in the target image area based on the corresponding relation between the colors and the temperatures of the thermal imaging image.
And step S1033, determining the current body temperature data of the user according to the temperature data.
Exemplarily, a temperature set corresponding to the target image area, that is, a temperature set of the current body temperature of the user, is generated according to the temperature data corresponding to each pixel block; and then determining the current body temperature data of the user according to the temperature set of the current body temperature of the user.
In some embodiments, the determining the current body temperature data of the user according to the temperature set of the current body temperature of the user includes the following steps:
selecting highest temperature data from the temperature set of the current body temperature of the user, and taking the highest temperature data as the current body temperature data of the user;
or averaging all the temperature data recorded in the temperature set of the current body temperature of the user to obtain an average temperature, and taking the average temperature as the current body temperature data of the user.
And step S104, adjusting the rotating speed of the rotating motor according to the current body temperature data of the user so as to adjust the wind speed of the fan.
The method comprises the steps of firstly presetting a corresponding relation between body temperature data and air supply speed, then determining the air supply speed corresponding to the current body temperature data of a user according to the corresponding relation, and finally adjusting the rotating speed of a rotating motor according to the air supply speed corresponding to the current body temperature data of the user so as to adjust the air speed of a fan.
In some embodiments, as shown in fig. 4, the adjusting the rotation speed of the rotating motor according to the current body temperature data of the user to adjust the wind speed of the fan specifically includes: step S1041 to step S1043.
And S1041, acquiring mapping relation data between preset body temperature data and the wind speed of the fan.
For example, a mapping relation table between body temperature data and the wind speed of the fan may be preset, and the mapping relation data between the body temperature data and the wind speed of the fan may be recorded in the mapping relation table. The mapping table may be stored in a memory of the fan or on a device communicatively interconnected to the fan.
Step S1042, determining the wind speed of the fan corresponding to the current body temperature data according to the mapping relation data.
The mapping relation data represents the corresponding relation between the body temperature data and the wind speed of the fan, and the wind speed of the air supply required by the current state of the user is determined according to the current body temperature data, namely the wind speed corresponding to the current body temperature data of the user is determined.
And S1043, adjusting the rotating speed of the rotating motor according to the wind speed corresponding to the current body temperature data.
The different rotating speeds of the rotating motor and the air supply speed have a direct proportion relation, namely the faster the rotating speed of the rotating motor is, the faster the corresponding air supply speed is, so that the air supply speed of the fan can be controlled by adjusting the rotating speed of the rotating motor, and the air speed corresponding to the current body temperature data can be obtained by adjusting the rotating speed of the rotating motor.
In some embodiments, after the fan performs air supply, the method specifically includes step S201 and step S202.
Step S201, determining the azimuth information of the target image area according to the thermal imaging image.
Exemplarily, after determining the target image area in the thermal imaging image by using the image recognition technology; focus aggregation is carried out on each target image area respectively to obtain a plurality of focal length change data of the thermal imaging camera; according to a plurality of focal length change data of the thermal imaging camera, respectively determining the distance information between the thermal imaging camera and each target image area, thereby determining the azimuth information of the target image area, wherein the focal length change data is the change information of the focal length of the thermal imaging camera.
And S202, adjusting the air supply range of the fan according to the azimuth information of the target image area.
And adjusting the air supply range of the fan according to the azimuth information of the user so that the user is in the air supply range of the fan, namely adjusting the air supply range of the fan according to the azimuth information of the target image area so that the user is in the air supply range of the fan.
In some embodiments, the determining the orientation information of the target image region in the thermal imaging image specifically includes the following steps:
if the number of target image areas in the thermal imaging map is multiple, acquiring azimuth information of each target image area, and determining leftmost azimuth information and rightmost azimuth information in the multiple azimuth information;
in some embodiments, the adjusting the blowing range of the fan according to the azimuth information of the target image area specifically includes the following steps:
and adjusting the air supply range of the fan according to the leftmost bit information and the rightmost bit information so as to supply air to the target image areas.
For example, if there is one target image area in the thermal imaging map, that is, there is one user appearing in the thermal imaging map, the orientation information of the user is determined, and the air blowing range of the fan is adjusted so that the user is within the air blowing range. However, sometimes there may be more than one target image area in the thermal imaging map, that is, there may be more than one user appearing in the thermal imaging map, for example, the thermal imaging map includes user a and user B, so it is necessary to adjust the blowing range of the fan so that user a and user B are both in the blowing range. Specifically, the leftmost bit information and the rightmost bit information in the azimuth information may be determined from the azimuth information of the target image area corresponding to the user a and the user B, and the air blowing range of the fan may be adjusted according to the leftmost bit information and the rightmost bit information, so that both the user a and the user B are within the air blowing range.
