  Measurement of the surface temperature of a human face using a radiation thermometer will be described with reference to FIG. FIG. 7 is a schematic diagram for explaining a measurement field of view and a measurement range of the infrared ray measurement unit. The radiation thermometer 200 has an infrared amount measurement unit that receives infrared rays from a predetermined measurement field 201, and outputs the surface temperature of the measurement object from the received infrared amounts. In a general radiation thermometer 200, the measurement visual field 201 extends radially toward the measurement direction. Therefore, the measurement range of the radiation thermometer 200 increases as the distance between the radiation thermometer 200 and the measurement object increases.

  When the person 204 is at the position (a) (when the distance between the radiation thermometer 200 and the person 204 is short), the measurement range 202 of the radiation thermometer 200 is within the range of the face. Therefore, the radiation thermometer 200 receives infrared rays from the face of the person 204. Therefore, the surface temperature of the face of the person 204 can be accurately measured.

  On the other hand, when the person 205 is at the position (b) (when the distance between the radiation thermometer 200 and the person 205 is long), the measurement range 203 of the radiation thermometer 200 exceeds the face area. Therefore, the radiation thermometer 200 receives not only infrared rays from the face of the person 205 but also infrared rays from the hair of the person 205, clothes worn by the person 205, and the surroundings of the person 205. Therefore, the surface temperature of the face of the person 205 cannot be measured accurately.

  Here, in the vehicle air conditioning control devices described in Patent Documents 1 and 2, since the position of the occupant can be assumed to be the position of a predetermined seat, the direction of the occupant with respect to the infrared sensor and the distance between the infrared sensor and the occupant are constant. is there. Therefore, if the infrared sensor is installed so that the measurement range of the infrared sensor is within the face area, the surface temperature of the human face can be accurately measured.

  However, for example, when measuring the temperature of a person in a room, the position of the person in the room and the distance between the person and the radiation thermometer are constant because it is not possible to determine where the person is in the room. Not. Therefore, the measurement range of the radiation thermometer exceeds the face area, and the surface temperature of the human face may not be accurately measured.

  Here, in the non-contact temperature measuring device described in Patent Document 3, since the thermoviewer is used to measure the temperature of the human face, it is not always necessary to grasp the distance between the thermoviewer and the person. Further, since the thermoviewer is generally more expensive than the radiation thermometer, this measuring apparatus is relatively expensive.

  Therefore, the human body temperature measuring device and the measuring method thereof according to the present invention have been made to solve the above-described problems, and in an environment where the position of the person is not fixed, the temperature of the person can be contacted relatively inexpensively. The purpose is to measure.

  In order to achieve the above object, a human body temperature measuring apparatus according to the present invention includes an infrared ray amount measuring unit that measures an infrared ray amount from a predetermined measurement field, and the infrared ray amount measuring unit attached to the infrared ray amount measuring unit. A movable part for changing the direction, direction control means for controlling the movable part so that the infrared amount measuring unit faces at least a part of the human body, and a distance between the infrared amount measuring part and at least a part of the human body. The distance acquisition means for acquiring, and the infrared amount measured by the infrared amount measuring unit toward at least a part of the human body based on the distance acquired by the distance acquisition means to correct the temperature of at least a part of the human body And a temperature correction means for acquiring.

  In order to achieve the above object, a human body temperature measurement method according to the present invention includes an imaging process, and an image analysis for recognizing at least a part of a human body reflected in the image by analyzing an image captured in the imaging process. And the infrared amount measuring unit is attached so that the infrared amount measuring unit faces at least a part of the human body based on the position of at least a part of the human body in the image recognized in the step and the image analyzing step A driving step for driving the movable portion, an infrared ray amount measuring step in which the infrared ray amount measuring unit measures an infrared ray amount toward at least a part of the human body, and a distance between the infrared ray amount measuring unit and at least a part of the human body.

[First Embodiment]
A human body temperature measuring apparatus and a human body temperature measuring method according to a first embodiment of the present invention will be described with reference to FIGS.

  First, the configuration of the human body temperature measuring apparatus according to the first embodiment will be described with reference to FIG. FIG. 1 is a block diagram showing a main configuration of a human body temperature measuring apparatus according to the first embodiment of the present invention.

  The human body temperature measurement apparatus 1 includes a photographing unit 11, an image analysis unit 21, an infrared ray measurement unit 31, a movable unit 41, a direction control unit 51, a distance measurement unit 61 (distance acquisition unit), and a temperature correction unit 71.

  The imaging unit 11 is, for example, a wide angle camera. The captured image is output as image data. The shooting unit 11 may be a video.

  The infrared amount measuring unit 31 has a predetermined measurement field that spreads radially in the measurement direction, receives infrared rays from the measurement field, and measures the amount of infrared rays. The amount of received infrared light is output as a voltage value, for example.

  The distance measuring unit 61 is an example of a distance acquiring unit, and is, for example, a PSD (Position Sensitive Detector). This is a so-called infrared reflection type sensor, based on the time from when infrared light is emitted toward the measurement direction until the infrared light is reflected by the measurement object and the reflected light is received. It is a sensor that measures the distance between the distance measuring unit 61 and its measurement object. The distance measuring unit 61 may be a sensor using ultrasonic waves.

  The imaging unit 11, the infrared amount measuring unit 31, and the distance measuring unit 61 are movable units such that the imaging direction of the imaging unit 11, the measuring direction of the infrared amount measuring unit 31, and the measuring direction of the distance measuring unit 61 are in the same direction. 41 are attached at substantially the same position. Therefore, the distance between the distance measurement unit 61 and the measurement object and the distance between the infrared ray measurement unit 31 and the measurement object are substantially the same.

  The movable part 41 is, for example, an actuator that moves in the pan / tilt direction. When the movable unit 41 moves, the photographing direction of the photographing unit 11, the measuring direction of the infrared amount measuring unit 31, and the measuring direction of the distance measuring unit 61 are simultaneously changed to the same direction.

  The image analysis unit 21 is connected to the photographing unit 11, detects the presence or absence of a human face in the image photographed by the photographing unit 11, and recognizes the position of the human face in the image. It is not always necessary to have a human face, for example, a human hand.

  The direction control unit 51 is connected to the image analysis unit 21 and controls the movable unit 41 based on the position of the human face recognized by the image analysis unit 21.

  The temperature correction unit 71 includes a temperature verification unit 72 and a temperature database 73. The temperature database 73 includes an infrared ray amount (voltage value), a distance between the infrared ray amount measuring unit 31 and the measurement object (a distance between the distance measurement unit 61 and the measurement object), and a corrected temperature (a surface of the measurement object). Multiple temperature relationships are stored.

  The temperature verification unit 72 is connected to the infrared amount measurement unit 31, the distance measurement unit 61, and the temperature database 73. The temperature collation unit 72 collates the infrared ray amount (voltage value) output from the infrared ray amount measurement unit 31 and the distance output from the distance measurement unit 61 with the data stored in the temperature database 73 to correct the corrected temperature. Is output.

  Next, the human body temperature measuring method according to the first embodiment will be described with reference to FIG. Hereinafter, the measurement target of the human body temperature measurement method 1 will be described as the face of a person in the room. FIG. 2 is a flowchart showing a human body temperature measuring method according to the first embodiment of the present invention.

  After the human body temperature measuring apparatus 1 is initialized (S1), the photographing unit 11 photographs an arbitrary space in the room (S2) and outputs the photographed image data.

  The image analysis unit 21 receives the image data output from the photographing unit 11 and detects whether or not a human face is included in the image (S3, S4). This detection method may be based on, for example, detection of a skin color area, or may be based on face image pattern matching.

  When the image analysis unit 21 cannot detect a human face in the image, the movable unit 41 performs a pan / tilt operation under the control of the direction control means 51 (S5). As a result, the shooting direction of the shooting unit 11 attached to the movable unit 41 changes (S6), and the shooting space changes. After the movable part 41 operates, the photographing part 11 again takes a picture (S2), and the image analysis part 21 analyzes the image (S3, S4). These processes are repeated until a human face is detected in the image (S2 to S6).

  On the other hand, when the image analysis unit 21 detects a person's face in the image, the image analysis unit 21 analyzes the position in the image where the person's face is located (S7), and obtains data related to the position. It outputs to the direction control means 51.

  The direction control unit 51 controls the movable unit 41 based on the data related to the position of the person's face so that the centers of the measurement ranges of the infrared amount measuring unit 31 and the distance measuring unit 61 coincide with the center of the person's face ( S8). As a result, the movable unit 41 performs a pan / tilt operation, and the measurement directions of the infrared amount measurement unit 31 and the distance measurement unit 61 face the center of the human face (S9).

  The infrared ray amount measuring unit 31 receives the infrared ray from the measurement visual field and measures the infrared ray amount after the measurement direction stops facing the person's face (S10). The distance measuring unit 61 measures the distance between the distance measuring unit 61 and the person's face after the measurement direction is stopped facing the person's face (S11).

  The measurement of the amount of infrared rays (S10) and the measurement of the distance (S11) may be performed simultaneously. When the distance measuring unit 61 is a sensor using infrared light, the distance is preferably measured before and after measuring the amount of infrared light. This is because if both measurements are performed simultaneously, the infrared amount measuring unit 31 receives the infrared rays emitted by the distance measuring unit 61 and cannot measure the desired amount of infrared rays.

  Processing of the temperature correction unit 71 will be described. When the measurement range of the infrared amount measuring unit 31 is within the face region (in the case of FIG. 7A), the infrared rays received by the infrared amount measuring unit 31 are substantially infrared rays from a human face. It is. Therefore, no correction is required, and the surface temperature of the human face can be obtained by converting the measured amount of infrared rays into temperature.

  On the other hand, when the measurement range of the infrared amount measuring unit 31 exceeds the region of the human face (in the case of FIG. 7B), the infrared rays received by the infrared amount measuring unit 31 are infrared rays from the human face. As well as infrared rays from things other than a person's face (the person's hair and clothes, the wall behind the person, etc.). Therefore, the measured amount of infrared rays is the total amount of these. Therefore, if this total amount is directly converted into temperature, the temperature does not coincide with the surface temperature of the human face.

  Furthermore, in the case where the measurement range of the infrared ray amount measuring unit 31 exceeds the area of the human face, the farther the infrared ray amount measuring unit 31 is from the human face, the closer the human face is to the measurement range of the infrared ray amount measuring unit 31. The percentage of the range becomes smaller.

  Therefore, the temperature correction means 71 corrects the infrared ray amount measured by the infrared ray amount measuring unit 31 as necessary to obtain the surface temperature of the human face (S12). Specifically, the temperature matching unit 72 is configured to measure the amount of infrared rays (for example, voltage value) measured by the infrared amount measuring unit 31 and the distance (distance measurement) between the infrared amount measuring unit 31 measured by the distance measuring unit 61 and the measurement object. The distance between the unit 61 and the measurement object) is input. Thereafter, the temperature verification unit 72 compares the input infrared amount and distance with data stored in the temperature database 73 in advance, and outputs the corrected temperature.

  Hereinafter, a robot to which the human body temperature measuring apparatus according to the first embodiment is applied will be described with reference to FIG. FIG. 3 is a perspective view of a robot to which the human body temperature measuring device according to the first embodiment of the present invention is applied.

  The robot 100 has a head portion 101 and a trunk portion 102. The head portion 101 is attached to the trunk portion 102 via the neck portion 103. The robot 100 includes the human body temperature measuring device 1 therein.

  The neck portion 103 has the function of the movable portion 41, and the head portion 101 moves in the pan / tilt direction. Inside the head 101 is a photographing unit 11, an infrared amount measuring unit 31, and a distance measuring unit 61, which perform photographing and measurement from the eyes 104.

  The robot 100 can obtain the surface temperature of the human face by the human body temperature measuring apparatus 1 and adjust the temperature of the air conditioner installed in the room according to the temperature. When the temperature is higher than a predetermined temperature, a voice such as “Is there a fever” or “Is a cold caught” can be output to the person.

  Hereinafter, effects of the human body temperature measurement device and the human body temperature measurement method according to the first embodiment will be described.

  According to this embodiment, the surface temperature of at least a part of the human body can be measured in an environment where the position of the person is not fixed, such as a room. In addition, this can be realized using a relatively inexpensive infrared amount meter.

  In addition, the human body temperature measuring apparatus 1 according to the present embodiment uses the infrared amount measured by the infrared amount measuring unit 31 even when the measurement range of the infrared amount measuring unit 31 exceeds the region of the human face. Since the correction is performed when the temperature is converted, the output result is a value close to the actual surface temperature of the human face.

[Second Embodiment]
A human body temperature measurement device and a human body temperature measurement method according to a second embodiment of the present invention will be described with reference to FIGS. 4 and 5. In addition, since this embodiment is a modification of 1st Embodiment, the same code | symbol is attached | subjected to the same part or similar part as 1st Embodiment, and duplication description is abbreviate | omitted.

  First, the structure of the human body temperature measuring device according to the second embodiment will be described with reference to FIG. FIG. 4 is a block diagram showing a main configuration of a human body temperature measuring apparatus according to the second embodiment of the present invention.

  The human body temperature measurement apparatus 1 includes an imaging unit 11, an image analysis unit 21, an infrared ray measurement unit 31, a movable unit 41, a direction control unit 51, a distance measurement unit 61 (distance acquisition unit), a temperature correction unit 71, and a guide light irradiation unit. 81 and a drive unit 91.

  The guide light irradiation unit 81 emits guide light in the irradiation direction. For example, an infrared light emitting LED is used for light emission of the guide light.

  The guide light irradiation unit 81, the infrared light amount measurement unit 31, and the distance measurement unit 61 are arranged such that the irradiation direction of the guide light irradiation unit 81, the measurement direction of the infrared light amount measurement unit 31, and the measurement direction of the distance measurement unit 61 are in the same direction. In addition, the movable part 41 is attached at substantially the same position.

  On the other hand, the photographing unit 11 is not attached to the movable part 41 but attached to the driving part 91. The imaging unit 11 is arranged at a position different from the guide light irradiation unit 81, the infrared amount measurement unit 31, and the distance measurement unit 61. The imaging direction of the imaging unit 11 is the irradiation direction of the guide light irradiation unit 81 and the infrared amount measurement unit. 31 and the measurement direction of the distance measuring unit 61 are different.

  The drive unit 91 is connected to the image analysis unit 21 and performs pan / tilt operation or stops based on the presence or absence of a human face in the image analyzed by the image analysis unit 21.

  Next, a human body temperature measuring method according to the second embodiment will be described with reference to FIG. FIG. 5 is a flowchart showing a human body temperature measuring method according to the second embodiment of the present invention.

  After the human body temperature measuring device 1 is initialized (S21), the guide light irradiation unit 81 continuously emits guide light (S22). After starting the irradiation of the guide light, the photographing unit 11 photographs an arbitrary space in the room (S23) and outputs the photographed image data.

  The image analysis unit 21 inputs the image data output from the photographing unit 11 and analyzes whether or not a human face is included in the image (S24, S25).

  If the image analysis unit 21 cannot detect a human face in the image, the drive unit 91 performs a pan / tilt operation (S26). As a result, the shooting direction of the shooting unit 11 attached to the drive unit 91 changes, and the space for shooting changes. After the operation of the drive unit 91 stops, the imaging unit 11 captures again (S23), and the image analysis unit 21 analyzes the image (S24, S25). These processes are repeated until a human face is detected in the image (S23 to S26).

  On the other hand, when the image analysis unit 21 detects a human face in the image, the image analysis unit 21 analyzes whether or not the guide light is radiated to the approximate center on the human face in the image. (S26, S27).

  If the image analysis unit 21 cannot detect the guide light at the approximate center on the human face, the movable unit 41 performs pan / tilt operation under the control of the direction control means 51 (S28). Thereby, the irradiation direction of the guide light irradiation part 81 attached to the movable part 41 changes (S29). After the operation of the movable unit 41 stops, the imaging unit 11 captures again (S30), and the image analysis unit 21 analyzes the image (S26). These processes are repeated until guide light is detected at the approximate center on the human face (S26 to S30).

  Note that the image analysis unit 21 is not approximately the center on the human face, but when the guide light is detected in the image, the image analysis unit 21 outputs data regarding the position to the direction control unit 51. Based on the information, the movable part 41 may be controlled (not shown).

  On the other hand, when the image analysis unit 21 can detect the guide light at substantially the center on the human face, the guide light is stopped (S31). Thereafter, the infrared amount measuring unit 31 measures the amount of infrared rays (S32), and the distance measuring unit 61 measures the distance between the distance measuring unit 61 and a human face (S33). The reason for measuring the amount of infrared light after stopping the guide light is to prevent the reflected light of the guide light from being added to the infrared light received by the infrared light amount measuring unit 31 when an infrared light emitting LED is used to emit the guide light. It is.

  After that, the temperature collation unit 72 collates the input infrared amount and distance with data stored in advance in the temperature database 73, and outputs the corrected temperature (S34).

  Hereinafter, a robot to which the human body temperature measuring apparatus according to the second embodiment is applied will be described.

  The robot 100 includes the respective units 21, 31, 41, 51, 61, 71, 81 excluding the photographing unit 11 and the driving unit 91. The photographing unit 11 and the driving unit 91 are installed on a wall in the room. The imaging unit 11 wirelessly transmits the captured image as data to the image analysis unit 21 inside the robot 100. Inside the head 101, there is an infrared amount measurement unit 31, a distance measurement unit 61, and a guide light irradiation unit 81, which perform measurement and irradiation from the eyes 104.

  Also by the human body temperature measuring device and the human body temperature measuring method according to the present embodiment, the same effects as those of the human body temperature measuring device and the human body temperature measuring method according to the first embodiment can be obtained.
