It may be a thermal image camera.

The deep body temperature estimation unit 12 estimates the deep body temperature of the subject 2 according to the deep body temperature estimation algorithm from the thermal image acquired by the thermal image acquisition unit 11, and outputs the estimated deep body temperature as a measurement result by the deep body temperature measuring device 10. It is a processing unit. The core body temperature estimation unit 12 volatilizes, for example, a non-volatile memory such as a flash memory holding a program including a core body temperature estimation algorithm, a readable / writable volatile memory such as a DRAM, and a program including a core body temperature estimation algorithm from the non-volatile memory. It is composed of a processor that executes the program after being loaded into the volatile memory, a microcomputer having an input / output port, and the like. The deep body temperature estimation algorithm loaded in the volatile memory can be changed by the control unit 14, but when the deep body temperature estimation algorithm is changed, the deep body temperature estimation unit 12 follows the changed deep body temperature estimation algorithm.

The personal authentication unit 13 is a processing unit that performs personal authentication of the person to be measured 2, and is composed of an imaging device 13a and an authentication processing unit 13b. The image pickup device 13a is a device that generates a visible light image by taking an image of the person to be measured 2, and is, for example, a digital camera for visible light. The authentication processing unit 13b is a processing unit that performs personal authentication according to an authentication algorithm held inside using an image obtained by imaging by the image pickup device 13a. For example, as personal authentication, an image obtained by the image pickup device 13a. By matching the characteristics in the above with the characteristics of the image corresponding to each item of the personal authentication held in advance, the personal information of the person to be measured 2, that is, the identification information, the age, the hairstyle, whether or not the glasses are worn, and so on. Identify at least one of your illness, gender, height, race, weight, and living information. The "specification" by the authentication processing unit 13b includes determining, predicting, and acquiring the above-mentioned personal information. The authentication processing unit 13b loads, for example, a non-volatile memory such as a flash memory holding a program including an authentication determination algorithm, a readable / writable volatile memory such as a DRAM, and a program including an authentication algorithm from the non-volatile memory to the volatile memory. It is composed of a processor that executes a program after this, and a microcomputer or the like equipped with an input / output port or the like. At this time, the authentication algorithm loaded in the volatile memory can be changed by the control unit 14, but when the authentication algorithm is changed, the authentication processing unit 13b performs personal authentication according to the changed authentication algorithm.

The personal authentication unit 13 is not limited to the configuration using an imaging device, and may be a card reader in which an individual ID such as an IC card is recorded. Further, the personal authentication unit 13 may perform personal authentication by referring to the database unit 15 described later.

The database unit 15 is a storage unit that holds personal information about a plurality of persons who can be the subject 2 (for example, an employee of a certain company and a person who may enter and leave the company), and is, for example, a flash. It is a non-volatile memory such as a memory. The database unit 15 may be not only a local storage unit but also a computer device or a cloud connected to the control unit 14 via a communication network. FIG. 4 is a diagram showing an example of personal information held in the database unit 15. Personal information includes an ID that identifies an individual, name, height, weight, normal core body temperature, face image (face image by visible light), face heat image (face image acquired by the heat image acquisition unit 11), and hairstyle. , The ratio of face length to width, type and type of clothes often worn, etc. are included.

The control unit 14 is a processing unit that changes the core body temperature estimation algorithm according to the result of personal authentication by the personal authentication unit 13.

More specifically, the control unit 14 collates the characteristics (face image, height, etc.) of the measured person 2 obtained by the personal authentication unit 13 with the personal information registered in the database unit 15, so that the measured person 2 To identify. Then, the control unit 14 acquires the detailed personal information of the person to be measured 2 by referring to the database unit 15 for the identified person 2, and the person to be measured 2 is based on the acquired personal information. The core body temperature estimation unit 12 is instructed to change to the optimum core body temperature estimation algorithm. As a modification of the core body temperature estimation algorithm, the control unit 14 identifies a portion of the subject 2 in the thermal image, which is suitable for estimating the core body temperature, and notifies the core body temperature estimation unit 12 of information indicating the identified portion. Therefore, the part used for estimating the core body temperature is changed.

The deep body temperature estimation unit 12, the authentication processing unit 13b, and the control unit 14 constituting the deep body temperature measuring device 10 may be realized by a common processor for a part or all of them. In that case, the non-volatile memory in which the program is held, the volatile memory, and the like may also be shared.

Next, the operation of the core body temperature measuring device 10 according to the present embodiment configured as described above will be described.

FIG. 5 is a flowchart showing the operation of the deep body temperature measuring device 10 (that is, the deep body temperature measuring method) according to the present embodiment.

First, the personal authentication unit 13 performs personal authentication of the person to be measured 2 (personal authentication step S10). Specifically, the image pickup device 13a takes an image of the person to be measured 2. Then, the authentication processing unit 13b uses the image obtained by the image pickup by the image pickup device 13a, and according to the authentication algorithm held inside, the identification information of the person to be measured 2 is obtained from the image obtained by the image pickup device 13a as personal authentication. , Age, hairstyle, wearing glasses, illness, gender, height, race, weight, and at least one of living information. In this personal authentication step S10, the control unit 14 may perform personal authentication by collating the result of personal authentication by the personal authentication unit 13 with the personal information of the database unit 15.

Next, the control unit 14 causes the thermal image acquisition unit 11 to acquire the thermal image of the person to be measured 2 by giving an operation instruction to the thermal image acquisition unit 11 (thermal image acquisition step S11). For example, the thermal image acquisition unit 11 acquires a thermal image by taking an image while scanning a space including the person to be measured 2 with a one-dimensional thermal image sensor, or the person to be measured with a two-dimensional thermal image sensor. A thermal image is acquired by taking an image without scanning the space including 2. At this time, the thermal image acquisition unit 11 may adjust the focus before imaging.

Next, the control unit 14 instructs the deep body temperature estimation unit 12 according to the result of the personal authentication (personal authentication step S10) by the personal authentication unit 13 to obtain the deep body temperature estimation algorithm held by the deep body temperature estimation unit 12. Change (control step S12). For example, the control unit 14 identifies the person to be measured 2 by collating the result of personal authentication by the personal authentication unit 13 with the personal information of the database unit 15, and the person to be measured is based on the personal information of the person to be measured 2. When it is found that the hairstyle of No. 2 is short hair, the forehead is designated as the part of the person to be measured 2 in the thermal image used for estimating the core body temperature to the core body temperature estimation unit 12.

Finally, the deep body temperature estimation unit 12 estimates the deep body temperature from the thermal image acquired by the thermal image acquisition unit 11 according to the deep body temperature estimation algorithm modified by the control unit 14 (deep body temperature estimation step S13). For example, when the control unit 14 designates the forehead as the part of the subject 2 in the thermal image used for estimating the core body temperature, the core body temperature estimation unit 12 uses the thermal image acquired by the thermal image acquisition unit 11. Of these, the core body temperature is estimated using the thermal image on the forehead of the subject 2.

The personal authentication step S10 and the thermal image acquisition step S11 are not limited to this order, and may be interchanged or may be performed in parallel.

6A and 6B are diagrams showing an operation example of the deep body temperature measuring device 10 according to the present embodiment. FIG. 6A illustrates how a plurality of subjects 2a and 2b are sequentially measured for core body temperature by the core body temperature measuring device 10. FIG. 6B shows an example in which the core body temperature estimation algorithm is changed according to the result of personal authentication.

As shown in FIG. 6A, the person to be measured 2a has a short hairstyle and wears glasses by personal authentication by the personal authentication unit 13 or personal authentication by the personal authentication unit 13 and the control unit 14. If not, it will be authenticated. As a result, the control unit 14 obtains thermal images of the forehead, eyes, cheeks, mouth and neck directly under the hair as an optimal core body temperature estimation algorithm for a person who has short hair and does not wear glasses. The method of estimating the core body temperature using the method (for example, “METHOD: A”) is instructed to the core body temperature estimation unit 12. As a result, the core body temperature estimation unit 12 estimates the core body temperature from the thermal image acquired by the thermal image acquisition unit 11 according to the core body temperature estimation algorithm (for example, “METHOD: A”) instructed by the control unit 14. ..

On the other hand, for the person to be measured 2b, the hairstyle is shaved, the glasses are not worn, and the mouth is in the mouth by the personal authentication by the personal authentication unit 13 or the personal authentication by the personal authentication unit 13 and the control unit 14. You will be authenticated if you are wearing a mask. As a result, the control unit 14 obtains thermal images of the forehead, both eyes, and the neck as an optimal core body temperature estimation algorithm for a person whose hairstyle is shaved, who does not wear glasses, and who wears a mask on his mouth. The method of estimating the core body temperature using the method (for example, “METHOD: B”) is instructed to the core body temperature estimation unit 12. As a result, the deep body temperature estimation unit 12 estimates the deep body temperature from the thermal image acquired by the thermal image acquisition unit 11 according to the deep body temperature estimation algorithm (for example, “METHOD: B”) instructed by the control unit 14. ..

In addition, as in the subject "ID003" shown in FIG. 6B, the hairstyle is short and the sunglasses are worn by the personal authentication by the personal authentication unit 13 or the personal authentication by the personal authentication unit 13 and the control unit 14. If it is authenticated that it is worn, as an optimal core body temperature estimation algorithm, a method of estimating core body temperature using thermal images on the forehead, both cheeks, mouth and neck (for example, "METHOD: K") is used. The control unit 14 instructs the deep body temperature estimation unit 12 to adopt the product.

Further, as in the case of the subject "ID004" shown in FIG. 6B, the hairstyle is long and the person wears sunglasses by the personal authentication by the personal authentication unit 13 or the personal authentication by the personal authentication unit 13 and the control unit 14. If it is certified that the person is wearing turtleneck clothes, the optimum core body temperature estimation algorithm is a method of estimating the core body temperature using thermal images of both cheeks and mouth (for example, "METHOD:". The control unit 14 instructs the deep body temperature estimation unit 12 to adopt G ”).

In this way, the deep body temperature is estimated from the thermal image by the deep body temperature estimation algorithm according to the result of the personal authentication of the subject 2a obtained by the personal authentication unit 13, and the deep body temperature can be accurately estimated.

FIG. 7A is a diagram showing an example of a measurement result by the deep body temperature measuring device 10 according to the present embodiment.

As shown in this figure, each time the subject is detected by the core body temperature measuring device 10, the detected "day", "time", "ID", and "core body temperature estimation algorithm" are measured as the measurement results. , "Measurement site", "Environmental data", "Deep body temperature", "Measurement accuracy", "Remarks" are generated. The generated measurement result is output from the core body temperature measuring device 10 and displayed on the user interface device 4 or stored in the database unit 15.

In the measurement result, "day" and "time" are the day and time when this measurement was performed. The "ID" is an ID that identifies an individual obtained as a result of personal authentication. The "core body temperature estimation algorithm" is information indicating the type of the core body temperature estimation algorithm used for estimating the core body temperature. A "measurement site" is a site in a thermal image used to estimate core body temperature. The "environmental data" is environmental data such as room temperature, humidity, brightness and wind speed obtained from an environmental measuring instrument such as a thermometer, a hygrometer, an illuminance meter and an anemometer connected to the core body temperature measuring device 10. The "deep body temperature" is the deep body temperature estimated by the deep body temperature measuring device 10. The “measurement accuracy” is the estimated accuracy of the core body temperature, and is a value calculated by the core body temperature estimation unit 12.

Machine learning will be described later with reference to Modification 3. "Data security & sharing management" indicates the information sharing destination regarding the measurement result. The information sharing destination will be described later in the second embodiment.

In the measurement result shown in FIG. 7A, the following situation is shown as an example. That is, since the person to be measured with ID0004 usually wears a muffler and glasses, "METHOD G" is usually selected as a suitable core body temperature measurement algorithm (the date is "December 5, 2016"). , See the line where the ID is "ID004"). However, on March 1, 2017, the subject was not wearing a muffler and glasses, so this was recognized and a more accurate algorithm (“METHODA”) was selected.

FIG. 7B is a diagram showing another example of the measurement result by the deep body temperature measuring device 10 according to the present embodiment. Here, the history of measurement results for the same subject (in this example, "ID0001") is shown.

As shown in this figure, each time the person to be measured is detected by the core body temperature measuring device 10, the detected “day”, “time”, “goodly detected measurement site”, as the measurement result, "Measurement method that can be used daily", "Statistically suitable measurement method", "Priority item in measurement", and "Selected measurement method" are generated. The generated measurement result is output from the core body temperature measuring device 10 and displayed on the user interface device 4 or stored in the database unit 15.

In the measurement result, "day" and "time" are the day and time when this measurement was performed. A "goodly detected measurement site" is a measurement site that is well detected in the measurement. "Measurement method that can be used daily" is a list of core body temperature estimation algorithms that can measure core body temperature using "a well-detected measurement site". "Statistically suitable measurement method" is a core body temperature estimation algorithm judged to be statistically suitable from the history of measurement results, and appears most frequently in, for example, "measurement method that can be used daily". It is a core body temperature estimation algorithm or a core body temperature estimation algorithm that has been adopted most frequently in past measurements. "Items prioritized in measurement" are items designated in advance by the person to be measured, and indicate items such as giving priority to high "measurement accuracy" or having a short "measurement time". The "selected measurement method" is the core body temperature estimation algorithm adopted in the measurement.

In the measurement result shown in FIG. 7B, the following situation is shown as an example. That is, for the person to be measured with ID0001, in the measurement at 8:20 on March 3, 2017 (see the data in the first line of FIG. 7B), the available measurement methods are "A01", "A02", "A03", Based on "A04", the statistically preferable measurement method is "A02", and the priority item is "measurement accuracy", the measurement method "A01" is selected by the core body temperature measuring device 10. You can see that.

FIG. 8 is a diagram showing a comparative example between the measurement method by the deep body temperature measuring device 10 according to the first embodiment and the standard method. FIG. 8 shows the available deep body temperature measurement methods, the parts required for the deep body temperature measurement, the correlation between the measurement results when the experiment was performed with the deep body temperature measurement method and the output of the standard method, and the measurement accuracy of the experiment. Is shown. The standard method is, for example, a method of measuring by contacting any of the temperature of the mouth, the temperature of the ear, the temperature of the rectum, and the temperature of the armpit. 9A-9C are graphs showing an example of a measurement method using the core body temperature measuring device of FIG. 8 (“METHOD D1”, “METHOD D1C1” and “METHOD D2C1”, respectively) and a comparative example of a standard method. .. FIG. 10 is a diagram showing an example of a person to be measured using the measurement method by the core body temperature measuring device of FIG.

Taking FIGS. 8 to 10 as an example, a method of selecting a core body temperature measurement algorithm as shown in FIG. 7A will be described.

The person to be measured 2 in FIG. 10 is the person to be measured of ID0004 wearing the muffler and glasses shown in FIG. 7A. The core body temperature measurement algorithm applied to the subject 2 is determined by comparison with the measurement results by the standard method shown in FIGS. 8 and 9A to 9C. Since the person to be measured 2 wears a muffler and glasses, the parts of the face that are often detected are the forehead, cheeks, and mouth. When selecting a highly accurate algorithm as shown in FIG. 7A, “METHOD D2C1”, which has the highest correlation with the output of the standard method and the best measurement accuracy of the experiment, is selected from the comparison results of FIG. The algorithm.

I explained how to select the core body temperature measurement algorithm when the forehead, cheeks, and mouth can be detected, but when the subject 2 is measured, the mouth of the subject 2 cannot be detected well due to a bad angle or the like. In that case, the most accurate "METHOD D2C1" cannot be selected. In this case, the core body temperature measurement algorithms that can be selected are "METHOD D1" and "METHOD D1C1", but from FIG. 8, there is no big difference in the measurement accuracy between "METHOD D1" and "METHOD D1C1". At this time, if there is a "priority item in measurement" shown in FIG. 7B or if the subject gives an instruction of a priority item, the core body temperature measurement algorithm is selected according to the priority item.

For example, when the priority item is the measurement accuracy, as shown in FIG. 8, since there is no difference in the measurement accuracy of the experiments of "METHOD D1" and "METHOD D1C1", there is a correlation with the output of the standard method. select. As shown in FIG. 8, “METHOD D1C1”, which has a high correlation with the output of the standard method, is selected.

Alternatively, when the subject 2 instructed to reduce the calculation time, the correlation between the output of the standard method of "METHOD D1" and "METHOD D1C1", as shown in FIG. Since there is no big difference in the measurement accuracy of the experiment, it is possible to select "METHOD D1", which has few measurement items and shortens the calculation time.
