As shown in fig. 2, an embodiment of the present invention provides a method for detecting a position of a human body, the method being performed by a controller of an air conditioner, the method including:
at step 202, raw ambient temperature data is obtained.
In the embodiment of the present invention, the original ambient temperature data is acquired by a thermal imaging sensor, and specifically, the thermal imaging sensor of the air conditioning equipment acquires the original ambient temperature data and sends the original ambient temperature data to the controller, and the controller acquires the original ambient temperature data.
And step 204, determining the attenuated ambient temperature according to the original ambient temperature data.
The attenuated ambient temperature is obtained from the raw ambient temperature data, and specifically the controller determines the attenuated ambient temperature from the raw ambient temperature data.
In some embodiments, as a specific implementation manner of step 204, as shown in fig. 3, the method includes:
In the embodiment of the invention, the original environment temperature data acquired by the thermal imaging sensor can be an original environment temperature image, the original environment temperature image is obtained by combining a plurality of pixel points, and each pixel point represents a temperature, so that the controller acquires the pixel points in the original environment image.
And 304, sequencing the pixel points based on the bubble sequencing algorithm to determine the attenuated ambient temperature.
Bubble sort is a process of swapping when the pair of elements is out of order by repeatedly scanning the sequence to be sorted and comparing each pair of adjacent elements, and looping the process until no two adjacent elements can be swapped. Specifically, the controller sorts the pixel points in the original image based on the bubble sorting method to determine the attenuated ambient temperature.
In some embodiments, as an implementation of step 304, as shown in fig. 4, the method further includes:
and 402, sequencing the pixel points from large to small or from small to large based on the bubble sequencing algorithm.
And facilitating the subsequent determination of the attenuated ambient temperature, and ordering the pixel points in the original ambient temperature image. Specifically, the pixel points may be sorted in an ascending or descending manner, that is, the controller sorts the pixel points from large to small or from small to large based on the bubble sorting algorithm.
Specifically, the controller obtains the median of the sorted pixel points. Illustratively, when the number of the pixel points is singular, only one median value exists after the ordering; when the number of the pixel points is complex, two medians can be obtained after sorting, and the average value of the two medians is taken as a median. For example, the number of the pixels is 2048, and after the pixels are sorted, the average value of the 1024 th data and the 1025 th data is a median value.
And step 406, taking the median of the sorted pixel points as the attenuated ambient temperature.
Generally, the air conditioning equipment is installed at a high position and has a wide field of view, so that the ambient temperature in the sampling data of the thermal imaging sensor is relatively high, and the temperature median value can be used as the attenuated ambient temperature. Specifically, the controller takes the median of the sorted pixels as the attenuated ambient temperature.
In some embodiments, as another specific implementation manner of step 204, as shown in fig. 5, the method includes:
In the embodiment of the invention, in order to improve the operation efficiency, when other high-temperature objects are not considered, the average value of the pixel points can be used as the ambient temperature after attenuation. Specifically, the controller obtains pixel points in the original environment temperature image, wherein each pixel point represents a temperature. Then, the average value of the pixel points in the original environment temperature image can be calculated without sorting, and finally, the calculated average value is used as the environment temperature after attenuation, so that the calculation time can be saved. And when the object in the environment is determined to be a human body or not in the follow-up process, the human body can be regarded as the human body as long as the human body temperature is higher than the average value by judging whether the human body temperature is higher than the average value or not.
The actual environment temperature data are acquired through an environment temperature sensor, specifically, the environment temperature sensor of the air conditioning equipment acquires the actual environment temperature data and then sends the actual environment temperature data to the controller, and the controller acquires the actual environment temperature data.
And 208, determining an ambient temperature attenuation rate according to the actual ambient temperature data and the attenuated ambient temperature.
In the embodiment of the invention, the calculation formula for calculating the ambient temperature attenuation rate is as follows:
the controller obtains the actual environment temperature data and the attenuated environment temperature, and then calculates the environment temperature attenuation rate through the calculation formula, and specifically, the controller obtains the environment temperature attenuation rate by dividing the attenuated environment temperature by the actual environment temperature data.
And 210, determining the attenuated human body temperature range according to the environment temperature attenuation rate and the normal human body temperature range.
In the embodiment of the invention, the calculation formula for calculating the attenuated human body temperature range is as follows (formula II):
the attenuated human body temperature range is normal human body temperature range multiplied by ambient temperature attenuation rate (formula two)
In the embodiment of the present invention, a normal human body temperature range may be set in advance, for example, the normal human body temperature range is 34 to 37 ℃, and after the controller obtains the ambient temperature attenuation rate through calculation of the formula one, the attenuated human body temperature range may be obtained through calculation of the formula two, that is, the controller may obtain the attenuated human body temperature range by changing the normal human body temperature range x the ambient temperature attenuation rate.
And step 212, determining the position of the human body based on the attenuated human body temperature range.
And after the attenuated human body temperature range is determined, determining the position of the human body based on the attenuated human body temperature range. Specifically, by judging whether the temperature of the object in the environment is within the attenuated human body temperature range, if the temperature of the object in the environment is within the attenuated human body temperature range, the object is determined to be a human body. The positions of the pixel points in the original environment temperature image are determined, so that whether the object is a human body can be determined by judging the temperature range of the pixel points, the positions of the human body are determined based on the positions of the pixel points in the original environment temperature image, and air supply or people avoidance of subsequent air conditioning equipment can be conveniently controlled.
To facilitate an understanding of the invention, examples are given below. Illustratively, the thermal imaging sensor is arranged on the air conditioning equipment, the angle is adjusted downwards, after a human body is detected, detection information is sent to the controller, the controller sends an instruction to the air conditioner to adjust the swing of wind to blow the human body, the room temperature is 30 ℃, the body temperature is 36.4 ℃, the detection distance of the thermal imaging sensor is about 1m, and after the method is used, the detection distance is increased to about 2.7 m. When a human body is 2m in front of the thermal imaging sensor, the median of the pixel points is calculated to be 13 ℃, the attenuation rate is 43.3%, the temperature range of the attenuated human body is 14.7-16 ℃, objects in the temperature range can be regarded as the human body, and then the position of the human body is determined according to the position of the pixel points.
