Description

[0001] The present invention relates to an object health state determining method and system,

The present invention relates to a method and system for determining an object health state, and more particularly, to a method and system for determining an object health state using object recognition.

Methods for determining the health status of a person or an animal include doctor interview, blood test, computer tomography (CT), and magnetic resonance imaging (MRI). In addition, as a method of determining the health state, a physician may judge biometric information of an object photographed by a camera or compare the biometric information sensed by the biometric information detection means of the object with a predetermined reference value to determine the health state of the object And the like.

However, since the above-described conventional object health state determination method considers only the present judgment time, it is not easy to reliably diagnose the present state of health which is connected to the previous state and shows different modes.

For example, in a case where it is necessary to judge the health state of a large number of objects in a specific atmosphere such as an airport, a passenger terminal, a national main facility, or the like in a specific atmosphere such as a specific place or an influenza atmosphere, When the body temperature is higher than a certain temperature, it is assumed that the health of the object is abnormal.

In particular, since most thermal cameras have an error of about 2 ° C depending on the ambient temperature of the object, there is a problem that the reliability of body temperature of an object photographed by a thermal camera is very low.

As described above, in the technical field for determining the health state of an object, there is a need for an effective method for quickly determining the health state of the object with a certain degree of reliability.

Hereinafter, preferred embodiments will be described in detail with reference to the accompanying drawings. In the following description, well-known functions or constructions are not described in detail to avoid unnecessarily obscuring the subject matter of the present invention. In order to clearly explain the present invention in the drawings, parts not related to the description are omitted, and similar parts are denoted by similar reference numerals throughout the specification.

1 is a flowchart of a method for determining an object health state according to an embodiment of the present invention.

Referring to FIG. 1, a method for determining an object health condition according to an embodiment of the present invention includes a first step (S1) of acquiring a thermal image including at least one object and at least one black body from a thermal image camera, A second step S2 of detecting the face temperature of one object, a third step S3 of correcting the face temperature based on the difference between the measured temperature of the black body in the thermal image and the preset temperature of the black body, And a fourth step S4 of comparing the reference temperature range with the reference temperature range to determine the health state of the object.

In the first step S1, the object may be a person or an animal. A blackbody is a complete absorber that does not let out the light that comes into it again. In other words, when heat is applied to a blackbody, the heat in the blackbody goes out of the blackbody without loss in infrared form. Therefore, the temperature of the black body can be measured by measuring infrared rays on the black body.

The black body can be set to a predetermined temperature. For example, the black body may be set to a temperature of 32.0 ° C, 33.0 ° C, 33.5 ° C, 34.0 ° C, 34.5 ° C, 35.0 ° C, 36.0 ° C, 36.5 ° C, 37.2 ° C, 38.0 ° C, 38.5 ° C or 39.0 ° C. Here, the temperature of 32.0 캜 to 35.0 캜 is for the face temperature, and the temperature is for the body temperature of 36.0 캜 to 39.0 캜. If a plurality of black bodies is used, two or more temperatures can be set as reference temperatures.

For example, by setting the first black body to 36.0 占 폚 and the second black body to 37.2 占 폚, the body temperature of the object is compared with the temperatures of the first black body and the second black body to determine whether the health state of the object is normal, It is possible to easily display in color on the screen. Particularly, when a plurality of black bodies are arranged in a line at a predetermined interval, it can be used as a reference temperature indicator.

The thermal camera is also called an infrared camera or an infrared (IR) camera. The thermal camera captures light of a predetermined wavelength emitted from an object according to temperature of an object or an animal (hereinafter referred to as an object) . The object emits light of the wavelength when it has a temperature higher than the absolute temperature (-273.15 ℃), and it emits far infrared rays of 8-14㎛ wavelength near 37 ℃ in humans.

In the second step S2, the object health state determination system connected to or provided with the thermal camera analyzes the thermal image acquired from the thermal image camera to recognize the face region of the object belonging to the ROI, The temperature is detected.

For example, the system may detect the highest temperature in the face region as the face temperature of the object according to the type of the thermal camera or the function of the image processing module mounted on the thermal camera, The face temperature of the object can be detected.

In a third step S3, the system corrects the body temperature or the face temperature of the object using a black body. That is, the system compares the temperature of the blackbody (the first blackbody temperature) detected through the thermal image with a predetermined temperature (the second blackbody temperature) of the blackbody, and calculates the difference between the first blackbody temperature and the second blackbody temperature And corrects the body temperature or the face temperature of the object to be detected.

According to the present step (S3), the error with respect to the temperature of the object detected from the thermal image can be corrected by the own error of the thermal image camera, the ambient temperature of the photographing place, and the like, The body temperature or the face temperature of the object can be obtained.

In other words, the thermal camera has its own error of ± 1 ° C even in the case of an advanced camera, and the error of body temperature or face temperature of the object obtained from the thermal image taken by this thermal camera becomes larger appear. Therefore, the conventional method of detecting the body temperature of the object using the thermal camera has a limitation in that it can not be used for judging the health state of the object substantially because the reliability thereof is greatly deteriorated. However, And can be used to determine the health state of an object by reliably detecting the temperature of the object by correcting the body temperature or the face temperature of the object.

In a fourth step S4, the system determines whether the object is in a health state based on the corrected body temperature or the face temperature. For example, the system compares at least one of the calibrated body temperature and the face temperature with at least one reference temperature for the body temperature of the object and, based on the comparison result, determines whether the first signal or health of the object It is possible to output the second signal for the state no abnormality.

Here, the reference temperature of the object may include a first reference temperature for the body temperature and a second reference temperature for the face temperature, and the first reference temperature and the second reference temperature may include an upper limit value and a lower limit value, respectively. Typically, the face temperature may be about 2 ° C lower than the body temperature of the object detected through the thermal image.

According to this embodiment, when a body temperature or a face temperature of an object is measured using a thermal camera, the body temperature or the face temperature is effectively corrected using a black body, and the health state of the object is determined using the body temperature or the face temperature of the object It is possible to provide a method of judging object health state that can be usefully used in a system.

2 is a block diagram of an object health state determination system according to an embodiment of the present invention.

2, the object health state determination system 10 includes a thermal image camera 11, an image processing module 12, a correction processing module 13, and a control module 14.

The thermal imaging camera 11 photographs the object 2 and the black bodies 111 and 112 together and generates a thermal image including at least one object 2 and a plurality of black bodies 111 and 112. The first black body 111 is set to the temperature of the first reference value and the second black body 112 is set to the temperature of the second reference value.

The image processing module 12 recognizes the object 2, the first black body 111 and the second black body 112 by imaging the thermal image received from the thermal imaging camera 11 and connected to the thermal imaging camera 11. [ The image processing module 12 distinguishes the body and the face of the object 2, detects the body temperature having the highest temperature in the body region excluding the face portion, and the face temperature having the highest temperature in the face region. The image processing module 12 detects the first temperature of the first black body 111 and the second temperature of the second black body 112. [

The correction processing module 13 compares the detected temperature of the black body of at least one of the first black body 111 and the second black body 112 with the temperature of the predetermined reference value with respect to the black body and compares the detected temperature with the temperature difference Adjusts the detection temperature of the object up or down.

When the temperature difference between the first black body 111 and the second black body 112 is different from each other, the temperature difference between the first black body 111 and the second black body 112 is equal to the average difference, Up or downward of the detection temperature of the gas.

The control module 14 compares the body temperature or the face temperature of the object corrected by the correction processing module 13 with the first reference value and the second reference value and outputs a signal indicating whether the health state of the object is abnormal according to the comparison result . Such an output signal may be used to drive an alarm in an alarm device or to display a predetermined form or image on a screen of an administrator terminal.

In addition, the control module 14 can control the operation of the thermal imaging camera 11, the image processing module 12, and the correction processing module 13, and can process signals and data transmission / reception therebetween. For example, the control module 14 manages the execution unit (process) of the program implementing the object health state determination method, allocates or releases the memory to the program, writes data to the auxiliary storage device, reads the recorded data And provide it to where it is needed.

3 is a flowchart of a method for determining an object health state according to another embodiment of the present invention.

Referring to FIG. 3, a method for determining an object health state according to an embodiment of the present invention includes a first step (S1) of acquiring a thermal image including at least one object and at least one black body through a thermal camera, (S3) of correcting the face temperature based on the difference between the temperature of the black body in the thermal image and the preset temperature of the black body, a third step (S3) of detecting the face temperature of the at least one object A fourth step S41 of processing the image of the camera disposed adjacent to the thermal camera for searching the database, a fourth step S42 of retrieving the object recognized by the image processing in the database, a disease history of the object retrieved from the database, A fourth step (S43) of extracting record data of at least one of a body temperature and a face temperature of the object from history information including at least one of a result and a medication history, And a fifth step of determining the health state of the object based on the donor body temperature and the record data.

Since the first to third steps S1 to S3 are substantially the same as the corresponding steps of FIG. 1, detailed description will be omitted.

However, in the present embodiment, when detecting the body temperature or the face temperature of the object in the thermal image based on the difference between the set temperature of the black body and the measured temperature, it is possible to have an additional correction value depending on the condition or condition of the object to be measured. For example, when measuring the temperature of an object using a thermal camera, the surface of the object to be measured plays a very important role. The emissivity of the surface is influenced by the structure of the surface (such as clothes on clothes) Water drops, snow, frost, etc.) and handbags (hats, bags, etc.). Therefore, when acquiring a thermal image for an object by using the system of the present embodiment, it is preferable to shoot the object in a dry state in which a thick coat is removed without wearing a hat or a bag on the head or upper body of the object, In an environment where it is difficult to set an atmosphere, it is preferable to determine the health state of the object around the face temperature rather than the body temperature to prevent the occurrence of an error.

In step 4A (S41), the object health state judgment system for executing the method of the present embodiment processes an image photographed by a camera (hereinafter referred to as a video camera) disposed adjacent to the thermal image camera. Then, the face of the object is recognized by the image processing.

The video camera includes a digital camera and shoots a still image or a moving image. The image camera is for acquiring a separate camera image in consideration of the difficulty of recognizing the face of the object by a thermal image. If the thermal camera is to provide a common still image or moving image at the same time, .

In step 4B (S42), the system retrieves a face-recognized object from a database storing face information of objects. The database may be integrated into the object health state determination system, but is not limited thereto. For example, the database may be implemented as at least a part of a database system such as a government agency or a separate higher authority (government agency, police agency, etc.) connected to the present system via a network. In this case, unlike a case where the number of objects is less than a certain number or is limited within a predetermined range, a database storing face information of a whole city, region, or nation can be implemented.

In step 4C (S43), the system extracts record data on body temperature or face temperature of the pre-stored object in the database. According to this step, even when it is difficult to interlock with a specific history information database due to a current issue such as personal information protection, only a specific field item of a specific history information database and a field item (body temperature, face temperature, etc. of the object) Or a distributed database that stores the data.

In other words, in the present embodiment, the database or the distributed database can store the entire history information such as the disease history, the health examination result, and the medication history of the object. However, only the history data of the body temperature and the face temperature Can be stored. That is, the method of the present embodiment can be implemented using a database storing only the body temperature and the face temperature of the object according to the database usage environment.

In addition, if a database in which the body temperature or the face temperature of an object is sequentially recorded by date or time is prepared, the health state of the current object is determined by a part of the previous history information of the object (body temperature and face temperature) So that it can be usefully used.

Next, the system determines whether there is record data on the body temperature or the face temperature in the history information or the history information of the object (S51).

As a result of the determination in step S51, if there is recording data, the system determines whether the body temperature or the face temperature of the object detected on the deterioration phase and corrected based on the temperature of the black body is greater than the maximum value of the body temperature or the face temperature of the recording data (S52). If it is determined that the body temperature or the face temperature of the object is greater than the maximum value of the record data, a signal indicating that the health state of the object is abnormal is output (S53). If it is determined that the body temperature or the face temperature of the object is less than the highest value of the record data, a signal indicating that there is no abnormality in the health state of the object is output (S55).

On the other hand, if it is determined in step S51 that there is no recorded data, the system compares the body temperature or the face temperature of the object detected on the deterioration phase and based on the temperature of the black body with the first reference value and the second reference value (S54 ). For example, the system may determine whether at least one of the body temperature and the face temperature of the object is greater than or equal to a first reference value.

The first reference value may have a first reference value for body temperature of 37.2 占 폚 and have a first reference value for face temperature of 35.2 占 폚. And the second reference value may have 36.0 DEG C as the second reference value for the body temperature and 34.0 DEG C as the second reference value for the face temperature.

If at least one of the corrected face temperature and the body temperature is smaller than the first reference value and greater than the second reference value as a result of the determination in step S54, a signal indicating that the health state of the object is not abnormal is output (S54, S55) .

If at least one of the corrected face temperature and body temperature is equal to or greater than the first reference value or equal to or less than the second reference value as a result of the determination in step S54, the method outputs a signal that determines that the object is in a health state (S54, S53).

According to this embodiment, an object and a black body are photographed together, unlike a conventional thermal imaging camera, which simply corrects the temperature of the object based on the reflection temperature or the ambient temperature of the object, and the temperature and the temperature It is possible to measure the body temperature and the face temperature of a highly reliable object irrespective of the place of use or the thermal imaging time, as well as to measure the body temperature of the object through the face recognition of the object, (Eg, person) by comparing the previous data of the object such as the face temperature with the previous detected body temperature or face temperature, it is possible to extract the different points of the body temperature or the face temperature easily and accurately, It can be judged.

FIG. 4 is an exemplary view illustrating a result of compensating an object temperature using a black body in the object health state determination system of the present embodiment.

The graph of FIG. 4 shows the measured temperature on the straight line in the face region of the predetermined object on the deterioration phase obtained through the thermal camera in the object health state determination system according to the present embodiment. In the graph of FIG. 4, the vertical axis represents the temperature (占 폚) and the horizontal axis represents the position on the straight line in the face region of the object.

4, the first graph m0 represents the measured temperature on a predetermined straight line of the face region detected through the thermal image, and the second graph m1 and the third graph m3 indicate the temperature And the first correction value and the second correction value of the measured temperature corrected based on the difference between the detection temperatures of the black body.

According to the present embodiment, the temperature of the black body is compared with the detection temperature of the black body detected by the thermal camera, and the body temperature and the face temperature of the object are corrected by downward or upward shift by the difference between them, It is possible to detect the face temperature or the body temperature of the object with high accuracy regardless of the temperature of the object, the shooting time (body temperature difference between the morning, the lunch or the evening), or the difference between the infant and the adult, It can be effectively used for state determination.
