Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As described in the background art, the body surface temperature measured by infrared radiation does not represent the body internal temperature well, and thus cannot be applied to the diagnosis of the presence or absence of abnormality in the human body.
In order to solve the above problems, the present application provides a body temperature measuring method, which corrects and adjusts body surface temperature data obtained by non-contact measurement according to a corresponding first body temperature deviation value and a preset adjustment rule, so as to obtain corresponding target temperature data according to the body surface temperature data, and the target temperature data can reflect the body temperature of a human body more truly than the body surface temperature data, so as to further determine whether the body temperature is abnormal.
Fig. 1 shows a body temperature measuring device, which includes an infrared camera and a processing module, wherein the infrared camera may be an infrared photographic device such as a thermal infrared imager, and the processing module may be a device such as a computer with data processing capability. The body temperature measuring device can also be any other equipment with infrared image shooting and data processing capabilities, and the application does not limit the equipment.
In order to determine the corresponding body temperature according to the initial body temperature measured by infrared, experiments can be performed in advance to determine the deviation values of the first body temperature and the second body temperature and preset adjustment rules.
Specifically, the process of determining the preset adjustment rule corresponding to each age through an experiment includes:
the persons participating in the experiment were divided into a plurality of age groups by age in advance. For example, persons 0-10 years old may be divided into A groups, 11-65 years old into B groups, and persons over 65 years old into C groups.
The method comprises the steps that at a preset time point every day in a first experiment period, the environment temperature in a preset closed place is set to be 23 ℃, after a group A of people stay in the preset closed place for a long enough time, the temperature of the forehead part of all the people, namely the body surface temperature T _ head, is measured through a contact type temperature sensor, and the armpit temperature of all the people, namely the body temperature T _ body, is measured through a thermometer. According to the experimental results of each time, the relationship between the in-vivo temperature and the in-vitro temperature corresponding to the age value section corresponding to the group a at the preset time point, i.e. the preset adjustment rule T _ body _ a (T _ head), can be obtained.
Preferably, the preset time point is between six and seven am.
And simultaneously, respectively carrying out experiments on the group B and the group C to respectively obtain a preset adjustment rule T _ body _ B (T _ head) corresponding to the age value interval corresponding to the group B staff at the preset time point and a preset adjustment rule T _ body _ C (T _ head) corresponding to the age value interval corresponding to the group C staff at the preset time point.
The process of experimentally determining the second body temperature deviation value determined according to the age and the ambient temperature includes:
at the preset time point of every day in the second experiment period, the ambient temperature T _ atm in the preset closed place is set to be different preset temperatures, after the stay time of the group A personnel in the preset closed place is long enough, the temperature of the forehead part of all the personnel, namely the body surface temperature, is measured through the contact type temperature sensor, the difference value of the body surface temperature of each personnel in the group A at the preset temperature and the body surface temperature of the personnel at 23 ℃ is obtained, and the average difference value of the body surface temperature of the personnel in the group A at the preset temperature and the body surface temperature of the personnel at 23 ℃ is further obtained. According to the average difference values obtained by the group A personnel at all preset temperatures, the average difference value of the body surface temperature of the age value interval corresponding to the group A personnel at the preset temperature T _ atm and the body surface temperature at 23 ℃ can be generated, namely the expression GA (T _ atm) of the second body temperature deviation value.
And simultaneously carrying out experiments on the group B and the group C respectively to obtain an expression GB (T _ atm) of the average difference value between the body surface temperature of the age value interval corresponding to the group B at the preset temperature T _ atm and the body surface temperature at 23 ℃ and an expression GC (T _ atm) of the average difference value between the body surface temperature of the age value interval corresponding to the group C at the preset temperature T _ atm and the body surface temperature at 23 ℃.
The process of determining the first body temperature deviation value corresponding to each preset time period through experiments comprises the following steps:
under the constant temperature environment of 23 ℃, the armpit temperature of the human body participating in the experiment is collected as the human body temperature after a preset time period within 24 hours after the preset time point, and the change value of the human body temperature of each human body within 24 hours relative to the human body temperature at the preset time point is obtained. Preferably, the body temperature may be collected every one hour. The average value of the variation values of the human body temperature of all the human bodies participating in the experiment at each acquisition time point relative to the human body temperature at the preset time point is taken, so that the average variation value of the human body temperature at each acquisition time point relative to the human body temperature at the preset time point can be obtained. The average variation value may be expressed as (time1, T _ body _1-T _ body _1), (time2, T _ body _2-T _ head _1), … (time, T _ body _ k-T _ body _1), … (time j, T _ body _ j-T _ body _1), where time k represents the kth time period, T _ body _ k-T _ body _1 represents the average variation value of the body temperature of the human body at the kth time period with respect to a preset time point, and j represents the total number of time periods. According to the average change value, the change rule of the human body temperature along the time period, namely h (time) T _ body _ k-T _ body _1, can be obtained. The average change value of the body temperature of the human body at each acquisition time point relative to the body temperature at the preset time point can be obtained by acquiring the temperature of the forehead part of the human body participating in the experiment as the in-vivo temperature of the human body.
Example one
As shown in fig. 2, the process of measuring the body temperature of the user using the body temperature measuring device includes:
acquiring an infrared image shot by an infrared camera and a corresponding visible light image;
secondly, identifying a head image of the user contained in the infrared image, and determining the body surface temperature of the user according to the head image;
the infrared image can be subjected to image recognition, a user contained in the infrared image is recognized, and a head image of the user contained in the infrared image is further recognized. And then determining the head temperature of the user, namely the body surface temperature, by adopting a preset algorithm according to the head image.
Step three, determining the ambient temperature;
the environment temperature can be determined according to the temperature of the surrounding environment of the user in the infrared image, and the environment temperature of the environment where the user is located can also be determined by adopting any method such as determining the environment temperature through temperature data returned by a preset temperature sensor.
Acquiring the age of the user and the acquisition time of body surface temperature data;
the age of the user can be determined according to the age input by the user in advance, or can be determined according to the age of the user in the visible light image, or can be determined according to the age of the user recorded in the user data by performing image recognition on the visible light image and predicting the age of the user in the image, or according to the matching of the facial features of the user in the visible light image with the corresponding user data.
Fifthly, correcting body surface temperature data according to the age and the environment temperature of the user to generate corrected body surface temperature data;
the preset age interval to which the user belongs can be determined according to the age of the user, for example, when the age of the user does not exceed 10 years, the preset age interval to which the user belongs is determined to be a, and the second body temperature deviation value corresponding to the preset age interval to which the user belongs can be obtained through an expression GA (T _ atm) obtained through experiments. The second body temperature deviation value corresponding to each age and the environment temperature comprises the average difference value of the body surface temperature of the age value interval to which the age belongs at the environment temperature and the body surface temperature at 23 ℃.
And correcting body surface temperature data according to the age of the user and a second body temperature deviation value corresponding to the environment temperature, wherein the corrected body surface temperature data represents the body surface temperature of the user at the environment temperature of 23 ℃. And then, adjusting the corrected body surface temperature data according to a preset adjustment rule corresponding to the age of the user to generate corresponding internal temperature data, wherein the internal temperature data represents the internal temperature of the user in the environment with the collection time and the temperature of 23 ℃. The preset adjustment rule corresponding to each age comprises a relational expression between the in-vivo temperature and the in-vitro temperature of the human body in the age value interval to which the age belongs at a preset time point.
Step six, determining a first body temperature deviation value corresponding to the acquisition time according to a corresponding relation between preset time and the first body temperature deviation value;
and step seven, correcting the internal temperature data according to the corresponding first body temperature deviation value to generate target body temperature data.
In order to avoid the influence of the time for measuring the body temperature on the judgment of whether the measured body temperature data is abnormal or not, a first body temperature deviation value corresponding to the acquisition time can be acquired, and the measured body temperature data is corrected by using the first body temperature deviation value. The first body temperature deviation value corresponding to the acquisition time comprises an average change value of the body temperature of the human body at the acquisition time relative to the body temperature at a preset time point. Because the internal temperature data represents the internal temperature of the user in the environment of acquisition time and 23 ℃, the target body temperature data obtained after the correction of the first body temperature deviation value represents the internal temperature of the user in the environment of 23 ℃ at the preset time point, so that the influence of the environmental temperature and the time of the environment on the body temperature degrees is eliminated, and the body temperature degrees can more accurately indicate the real state of the human body.
Preferably, the normal body temperature range of the human body in the environment of 23 ℃ at the preset time point of each age group can be predetermined. When the generated target body temperature data is not in the corresponding normal body temperature range, a warning signal can be sent to the user.
