The temperature scanning matrix comprises a plurality of temperature point location coordinates and temperatures corresponding to the temperature point location coordinates. In this embodiment, the infrared thermopile sensor may scan and acquire a temperature scan data matrix of the indoor target object, for example, the infrared thermopile sensor with 32 × 32 matrix points may be used to acquire the relative temperature of the target object.

The temperature scanning data matrix comprises a plurality of temperature point location coordinates and the temperature of the temperature point location coordinates, if the temperature corresponding to the temperature point location coordinates is relatively high, temperature points on the target object are considered to be represented, and if the temperature corresponding to the temperature point location coordinates is relatively low or is the same as the ambient temperature, the temperature point location is not considered to be the temperature point location on the target object, so that the shape formed by the temperature point location coordinates with the relative temperature is the temperature imaging shape of the target object.
Step 130: and matching the temperature imaging shape with the pre-stored human body temperature imaging data to determine whether the target object is a human body.
Performing temperature imaging shapes formed by a temperature scanning data matrix of the target object and pre-stored human body temperature imaging data, wherein the human body temperature imaging data comprise temperature imaging shapes which are determined according to the temperature scanning matrix corresponding to different human body postures in advance, and if the temperature imaging shapes of the target object can be matched with the corresponding human body temperature imaging data, the target object is a human body, and executing step 140; if the temperature imaging shape of the target object cannot be matched with the corresponding human body temperature imaging data, it indicates that the target object is not a human body, step 110 is executed, and scanning is performed again.
Step 140: and when the target object is a human body, determining the bare occupation ratio of the target object.
And when the target object is determined to be a human body, determining the exposure proportion of the target object, namely the human body, wherein the exposure proportion is the proportion of the number of the high-temperature point locations in the temperature scanning data matrix of the target object to the number of the temperature point locations of the temperature scanning matrix corresponding to the human body temperature imaging data matched with the target object. In this embodiment, the naked state means that the user does not wear the clothes or covers the quilt. For example, when a user sleeps, the arms of the user are exposed when the user stretches out of the quilt; if the quilt is not covered on the head, the head is exposed; if the user covers the quilt on the lower body but not on the upper body, the upper body is exposed.
Step 150: and controlling the air outlet mode of the air conditioner according to the exposed ratio.
The exposed ratio can well reflect the situation that a user covers a quilt or wears clothes, therefore, the air outlet mode of the air conditioner is adjusted according to the exposed ratio, the use requirement of the user can be met, the air outlet mode is intelligently adjusted according to the exposed ratio of the user, supercooling or overheating is prevented, and the comfortable experience of the user is enhanced.
According to the air conditioner control method, the temperature imaging shape of the target object is matched with the human body temperature imaging data, the non-human body target is removed, then the exposed ratio is determined according to the ratio of the number of high-temperature points in the temperature scanning data matrix of the target object to the number of temperature points of the corresponding human body temperature imaging data, whether a user covers a quilt or wears clothes can be determined, the air outlet mode of the air conditioner is adjusted according to the exposed ratio, the air outlet can be adjusted according to the actual condition of the user, and the user can be prevented from catching a cold due to too low temperature in the sleeping process.
In practical use, the infrared thermopile sensor receives thermal radiation to sense the temperature of a target object, and detects a plurality of temperature points and the temperature of the points. In order to facilitate matching and comparing the detected target object with the pre-stored human body temperature imaging data, the temperature imaging shape of the target object should be formed according to the temperature scanning data matrix. On the basis of fig. 2, referring to fig. 3, step 120 includes the following substeps 120-1 through 120-2.
Step 120-1: and determining effective points in the temperature scanning data matrix.
An active site is a site that is at a temperature above ambient temperature. For example, if the user lies on a bed, the average temperature of the bed is 19 ℃, and the points in the temperature scan data matrix with the temperature higher than 19 ℃ are all valid points.
Step 120-2: and determining the shape formed by the plurality of effective points as the temperature imaging shape of the target object.
It can be understood that the coordinates of the temperature point represent the physical position of the point, and temperature imaging shapes representing the outline of the target object can be formed according to the coordinate set of the effective points.
Since the user may have different postures when resting, such as lying on his side, lying on his bed, lying in a bold letter, etc., and further, the user may have different postures when resting in different places, such as lying on a sofa may have different postures than lying on a bed, and also have different postures than lying on a chair, on the basis of fig. 3, referring to fig. 4, the following gives step 130 a possible embodiment, step 130 comprises the sub-steps of step 130-1 to step 130-3.
Step 130-1: and comparing the temperature imaging shape with the pre-stored human body temperature imaging data to determine the contact ratio.
The human body temperature imaging data comprises temperature imaging shapes determined by temperature scanning matrixes corresponding to different human body postures, the temperature imaging shapes of the target objects are preprocessed, for example, the modes include but are not limited to mirror images, turning, rotating, stretching and the like, and then the preprocessed temperature imaging shapes are compared with prestored human body temperature imaging data by turns to determine the coincidence degree.
In possible embodiments, after generating the temperature imaging shape, comparing the temperature imaging shape with pre-stored human body temperature imaging data one by one to determine the degree of coincidence, and then preprocessing the temperature imaging shape in at least preprocessing manners such as mirroring, turning, rotating, stretching and the like, and comparing the pre-stored human body temperature imaging shape to determine the degree of coincidence of the preprocessed temperature imaging shape with the human body temperature imaging data.
If different degrees of overlap are obtained before and after the pretreatment, the maximum value of the degrees of overlap obtained is retained, and the remainder is discarded.
And step 130-2, judging whether the contact ratio is higher than an th threshold value.
When the coincidence degree is higher than or equal to the th threshold value, the temperature imaging shape of the target object can be matched with the corresponding human body temperature imaging data, the target object is determined to be a human body, step 140 is executed, when the coincidence degree is lower than the th threshold value, the temperature imaging shape of the target object cannot be matched with the corresponding human body temperature imaging data, the target object is determined not to be a human body, step 110 is executed, and scanning is conducted again.
For example, referring to fig. 5, when the user exposes the head, arms and part of the body out of the quilt, the temperature imaging shape determined according to the temperature scanning data matrix only includes the part exposed out of the quilt, when the temperature imaging shape is matched and compared with the human body temperature imaging data, and when the corresponding human body temperature imaging exists, so that the coincidence degree of the temperature imaging shape of the target object and the human body temperature imaging data reaches the th threshold (for example, 20%), it is determined that the corresponding human body temperature imaging exists and corresponds to the target object, that is, the target object is determined to be a human body.
In the embodiment, the exposure refers to that the human body is not covered or has no clothes, possible implementation modes for determining the exposure proportion of the target object are provided below, and referring to fig. 6 on the basis of fig. 4, the step 140 comprises the following substeps of 140-1-140-2.
Step 140-1: and acquiring the number of high-temperature point locations of a temperature scanning data matrix of the target object and the number of corresponding temperature point locations of human body temperature imaging.
And acquiring the number of high-temperature point locations of a temperature scanning data matrix of the target object, wherein the number of the high-temperature point locations refers to the temperature point locations with the temperature higher than a temperature threshold value. In practical situations, since the infrared thermopile receives the radiation of an object to sense the temperature information of the object, and for a human body, the skin surface has a temperature, so that the skin surface continuously emits the thermal radiation, and therefore, the infrared thermopile sensor can sense the temperature, and if a quilt is covered or the clothes are worn, the temperature of the surface of the human body can be maintained, but the surface temperature of the quilt or the clothes is close to the ambient temperature, so that a temperature point with a temperature higher than a temperature threshold (which can be set according to the average temperature of the skin surface of the human body) can be determined as a part where a target object (i.e., the human body) is exposed.
The method comprises the steps of obtaining the number of high-temperature point locations, namely the number of temperature point locations with the temperature higher than a temperature threshold value, and obtaining the number of temperature point locations of a temperature scanning matrix corresponding to human body temperature imaging data matched with a target object, wherein the number of temperature point locations of the temperature scanning matrix corresponding to the human body temperature imaging data can be determined by using a human body or a human body model according to a test, and the number of temperature point locations of the temperature scanning matrix corresponding to the human body temperature imaging data is the number of all exposed temperature point locations corresponding to the human body.
Step 140-2: and determining the ratio of the number of the high-temperature point locations to the number of the corresponding temperature point locations of the human body temperature imaging as the bare ratio.
For example, with reference to fig. 5, if the number of the high temperature points in the temperature scan data matrix of the target object is N, and the number of the temperature points corresponding to the matched human body temperature imaging is M, the exposure ratio is N/M.
And after the bare ratio is determined, adjusting the air outlet mode of the air conditioner according to the bare ratio. In this embodiment, a second threshold is set, and when the exposure percentage is smaller than the second threshold, it indicates that the exposed part of the user is less, and air is blown out according to the current operation mode; i.e. the air conditioner remains in the current operation mode.
When the exposed ratio is greater than or equal to the second threshold, it indicates that the exposed part of the user is more, if the exposed part is not changed according to the current operation mode, the temperature is reduced, which may cause the user to catch a cold, therefore, when the exposed ratio is greater than or equal to the second threshold, the air is discharged according to the preset sleep air-out mode, which includes: the target temperature of the air conditioner is improved, and the air outlet speed of the air conditioner is reduced.
The second threshold may be set to a value greater than 50%, but is not limited thereto, and for example, may be set to 70%, when the exposure percentage reaches 70%, the target temperature of the air conditioner is increased, and the air outlet speed of the air conditioner is decreased. To prevent the user from catching a cold or catching a cold.
