Description

  The present invention relates to a person detection technique for detecting the position of a person existing in a section based on a thermal image detected from the section.

  Conventionally, as an air conditioning control system, a technology has been proposed in which a section where a person is present is specified and controlled to a comfortable air conditioning environment, and air conditioning and lighting are stopped for a section without a person (for example, Patent Document 1). 2 etc.). In such a system, as a technology for detecting people in the compartment, a thermal image (thermography) of the compartment is detected by a plurality of infrared sensors attached to the wall or ceiling, and the temperature distribution on the obtained compartment floor is used to detect the person. A person is detected by extracting a human region indicating the surface temperature of the human.

  One of infrared sensors that detect thermal images is a thermopile array sensor. When a thermopile array sensor is installed on the ceiling to detect a thermal image and measure the temperature distribution on the section floor, a human being as a heating element is detected at a higher temperature than the floor. At this time, by using a thermopile array sensor with a high resolution, it is possible to acquire human position information in units of about 10 cm. By detecting thermal images at a constant frame rate and continuously measuring the temperature distribution of the compartment floor, it is possible to track the movement of people and to detect the location information of people in the compartment in real time. Become.

For example, the user terminal 20 accesses the human detection device 10 in response to a user operation on a browser. By doing so, it has a function of acquiring the presence status of an arbitrary section D and displaying it on the screen.

[Human detection device]
The human detection device 10 includes, as main functional units, a sensor I / F unit 11, a communication I / F unit 12, a storage unit 13, a thermal image acquisition unit 14, a human tracking unit 15, a human detection determination unit 16, and situation data generation. A unit 17 and a distribution processing unit 18 are provided. Among these functional units, the thermal image acquisition unit 14, the human tracking unit 15, the human detection determination unit 16, the situation data generation unit 17, and the distribution processing unit 18 have a central processing unit (CPU) and a program that cooperate with each other. It is realized by.

The sensor I / F unit 11 has a function of performing data communication with each thermal image sensor T arranged in the section D via the communication line L1.
The communication I / F unit 12 has a function of performing data communication with the user terminal 20 via the communication line L2.

The storage unit 13 includes a storage device such as a hard disk or a semiconductor memory, and has a function of storing various processing information and programs used for human detection processing in the human detection device 10.
As main processing information, in addition to the thermal image acquired from each thermal image sensor T, there is human detection information indicating the human detection result for each seat arranged in the section D.

  FIG. 2 is an example of the arrangement of seats according to the first embodiment. FIG. 3 is a configuration example of the human detection information according to the first embodiment. In the human detection information, a name, a seat position (X coordinate value, Y coordinate value), and presence / absence of human detection are registered for each seat ID for identifying the seat. The X and Y coordinate values representing the seat position are coordinate values in the XY coordinate system based on the origin O set in advance in the section D.

For example, in the seat “P11”, the name of the resident “Azbil Taro” who owns this seat is registered as the name, and the seat positions of this seat are “X11” and “Y11”. “Yes” indicating that a person has been detected is registered in the presence / absence of person detection. Thereby, it is understood that the resident “Taro Azbil” is present in the seat “P11”.
In addition, the seat “P21” is registered with the name of the resident “Jiro Azbil” who owns this seat as the name, and the seat positions of this seat are “X21” and “Y21”. “None” indicating that no person is detected is registered in the presence / absence of person detection. Accordingly, it can be understood that the occupant “Jiro Azbil” is not present in the seat “P21”, that is, is away.

The thermal image acquisition unit 14 has a function of periodically acquiring a thermal image detected by the thermal image sensor T via the sensor I / F unit 11 and the communication line L1 and storing the thermal image in the storage unit 13.
The person tracking unit 15 performs time-series image processing on the thermal image stored in the storage unit 13 and tracks a high-temperature portion higher than the floor surface temperature of the floor included in the thermal image as a person. It has a function of detecting the position of a person existing in the section D. For the tracking method here, for example, a known method such as Patent Document 2 may be used.

The human detection determination unit 16 compares the human position obtained by the human tracking unit 15 with the seat position of each seat registered in the human detection information of the storage unit 13, so that a person is detected at these seat positions. It has the function to determine the presence or absence of human detection indicating whether or not it has been performed, and to update the presence or absence of human detection in the human detection information stored in the storage unit 13 based on the obtained detection result.
Regarding the presence / absence of human detection at each seat position, for example, the human position obtained by the human tracking unit 15 is compared with the seat position of each seat registered in the human detection information. If the difference is within the allowable range, it may be determined that there is human detection at the seat position.

  At this time, a threshold value is set at a time when the difference between the person position and the seat position is within the allowable range, and it is determined that there is human detection only when the threshold value is continuously within the allowable range for a time longer than the threshold value. It may be. Thereby, when it falls within the allowable range for a short time due to movement of a person or the like, it is not determined that there is human detection, and as a result, the presence or absence of human detection can be accurately determined.

  The situation data generation unit 17 detects the detection status of the person existing in the section D, specifically, the section D based on the presence / absence of the person detection related to each seat in the section D registered in the person detection information of the storage unit 13. It has a function of generating status data indicating the presence status regarding the occupant of the room and storing it in the storage unit 13. When the presence / absence detection of a person in a given seat indicates that there is detection, the occupancy status of the occupant of this seat is present.

  In response to the status request from the user terminal 20 received via the communication line L2 and the communication I / F unit 12, the distribution processing unit 18 acquires the status data of the section D from the storage unit 13, and the communication I / F. And a function of delivering to the user terminal 20 via the communication unit L2 and the communication line L2. The status data distributed to the user terminal 20 may be distributed on a Web screen created using a description language such as HTML, or may be distributed by mail or message.

[Operation of First Embodiment]
Next, the operation of the human detection device 10 according to the present embodiment will be described with reference to FIG. FIG. 4 is a sequence diagram illustrating a situation data generation operation and a situation data distribution operation according to the first embodiment. Here, a case will be described as an example in which the situation data includes the occupancy status of the occupant.

[Status data generation operation]
First, the presence status generation operation will be described.
When the thermal image transmission timing arrives (step 100), the thermal image sensor T detects the thermal image of the section D (step 101) and transmits the detected thermal image to the human detection device 10 (step 102).
At this time, the thermal image sensor T may return the detected thermal image to the human detection device 10 in response to an acquisition request from the human detection device 10.

The thermal image acquisition unit 14 acquires a thermal image of the section D by receiving the thermal image autonomously transmitted from the thermal image sensor T, and stores it in the storage unit 13 (step 103).
The person tracking unit 15 performs image processing on a time-series thermal image stored in the storage unit 13 and tracks a temperature part higher than the floor surface temperature as a person, thereby detecting a person's position in the section D. A tracking process is executed (step 104).

  Next, the person detection determination unit 16 compares the person position obtained by the person tracking unit 15 with the seat position of each seat registered in the person detection information in the storage unit 13, so that The presence / absence of human detection indicating whether or not a person has been detected is determined, and the presence / absence of human detection in the human detection information stored in the storage unit 13 is updated based on the obtained detection result (step 105).

  Thereafter, the situation data generation unit 17 stores situation data indicating the presence status of the occupants in the section D based on the presence / absence of the person detection related to each seat in the section D registered in the human detection information of the storage unit 13. The data is generated and stored in the storage unit 13 (step 106), and the series of situation data generation operations is terminated.

[Status data distribution operation]
Next, the situation data distribution operation will be described.
When a status request operation for requesting status data of the section D is performed, for example, by a browser (step 110), the user terminal 20 sends a status request from the user terminal 20 to the human detection device 10 via the communication line L2. It is transmitted (step 111).

When receiving the status request from the user terminal 20 via the communication I / F unit 12, the distribution processing unit 18 of the human detection device 10 acquires status data regarding the designated section D from the storage unit 13 (step 112). Then, the obtained situation data is distributed to the user terminal 20 that is the request source (step 113).
When the presence data distributed from the human detection device 10 is received, the user terminal 20 displays the received status data on the screen by the browser (step 114), and ends the series of status data distribution operations.

  FIG. 5 is a screen display example of status data (attended status). Here, the seat arrangement of the section D is displayed as a graphic symbol indicating a chair, a desk, or a table, and the presence / absence (seated / vacant) is identified and displayed by the color pattern of the graphic symbol. Thereby, the user can check the presence status regarding each occupant in the section D, that is, the presence / absence status very easily.

  The situation data is not limited to the Web screen format using the graphic symbol as shown in FIG. For example, for each occupant name included in the human detection information, a presence list indicating presence / absence based on presence / absence of corresponding human detection may be expressed in a Web screen format. Further, the presence list may be generated in a text format and distributed by mail or message.

[Effect of the first embodiment]
As described above, in the present embodiment, the human tracking unit 15 detects the human position by performing time-series image processing on the acquired thermal image and tracking the high-temperature portion, and the human detection determination unit 16 is detected. The presence / absence of the person at the seat position is determined by comparing the seat position of the person registered with the seat position registered in the person detection information, and the situation data generation unit 17 determines whether or not the person is detected for each seat. The status data indicating the detection status of the person existing in the section D is generated, and the distribution processing unit 18 distributes the status data to the user terminal 20.

  More specifically, the status data generation unit 17 indicates presence or absence as the occupancy status of the occupant based on the presence or absence of human detection of the seat related to the occupant in the section D registered in the human detection information. The situation data is generated.

  Thereby, the presence / absence of detection of the person at the seat position is determined based on the person position detected from the thermal image of the section D, and the situation data indicating the detection state of the person existing in the section D generated from the presence / absence of the person detection is obtained. Then, it is delivered to the user terminal 20 and displayed on the screen. Therefore, even if the user cannot visually confirm the floor or the compartment, for example, the user's presence of the presence status of the occupant, specifically the presence status of the occupant, can be used. The user terminal 20 can easily confirm remotely. For this reason, when the other party is absent, it is possible to avoid unnecessary attempts such as a user calling the other party or going to the other party in advance.

[Second Embodiment]
Next, a human detection device 10 according to a second embodiment of the present invention will be described.
In the first embodiment, the case where the presence status of the occupant is distributed as status detection data in the human detection device 10 as the detection status of the section D has been described as an example. In the present embodiment, as the detection status of the section D, a case will be described in which the usage status of a shared facility such as a meeting table or a conference table provided in the section D is distributed as status data instead of the presence status. .

  The situation data generation unit 17 generates and stores situation data indicating the usage status of the shared equipment in the section D based on the presence / absence of the person detection related to each seat in the section D registered in the person detection information of the storage unit 13. The unit 13 has a function of saving. The configuration of the human detection device 10 according to the present embodiment is the same as that shown in FIG. 1, and a detailed description thereof is omitted here.

  FIG. 6 is an arrangement example of seats according to the second embodiment. FIG. 7 is a configuration example of human detection information according to the second embodiment. In the human detection information, the name, the X coordinate, the Y coordinate, and the presence / absence of human detection are registered for each seat ID for identifying the seat. The X and Y coordinates are coordinate values in an XY coordinate system based on the origin O set in advance in the section D.

  For example, in the seat “P41”, the shared equipment “meeting table A” of this seat is registered as a name, and the seat positions of this seat are “X41” and “Y41”, and a person detects at this seat position. “None” indicating that no detection has been made is registered in the presence / absence of human detection. At this time, since the presence / absence of human detection in the other seat “P42” of the shared facility “meeting table A” also indicates “none”, the shared facility “meeting table A” is not used and can be used. I understand that.

  Also, in the seat “P51”, the shared equipment “conference table C” of this seat is registered as a name, and the seat positions of this seat are “X51” and “Y51”, and a person is detected at this seat position. “Yes” indicating that it has been registered is registered in the presence / absence of human detection. Thereby, it can be seen that the shared facility “Conference Table C” is used and cannot be used.

  Generally, if there is no person detection for all the seats provided in the shared facility, no one is using the shared facility. For this reason, the situation data generation unit 17 determines that this shared facility can be used. In addition, if any one of the seats provided in the shared facility has human detection, that shared facility is used by someone. For this reason, the situation data generation part 17 determines with this shared facility being unusable.

  FIG. 8 is a screen display example of status data (use status). Here, the seat arrangement of the section D is displayed as a graphic symbol indicating a chair, a desk, or a table, and the presence / absence (seated / vacant) is identified and displayed by the color pattern of the graphic symbol. Thereby, the user can confirm the utilization status regarding the shared facilities in the section D, that is, the availability status, very easily.

  Note that the usage status is not limited to the Web screen format using graphic symbols as shown in FIG. For example, for each shared facility name included in the human detection information, a use availability list indicating the corresponding use availability may be represented in a Web screen format. Further, the availability list may be generated in a text format and distributed by mail or message.

[Effect of the second embodiment]
As described above, in the present embodiment, the human tracking unit 15 detects the human position by performing time-series image processing on the acquired thermal image and tracking the high-temperature portion, and the human detection determination unit 16 is detected. The presence / absence of the person at the seat position is determined by comparing the seat position of the person registered with the seat position registered in the person detection information, and the situation data generation unit 17 determines whether or not the person is detected for each seat. The status data indicating the usage status related to the shared equipment in the section D is generated, and the distribution processing unit 18 distributes the status data to the user terminal 20.

  Thereby, the presence / absence of detection of a person at the seating position is determined based on the position of the person detected from the thermal image of the section D, and the situation data indicating the use situation regarding the shared equipment of the section D generated from the presence / absence of the person detection is obtained. It is distributed to the terminal 20 and displayed on the screen. Therefore, even when the user cannot visually confirm the floor or section, for example, it is possible to easily confirm the usage status of the shared facility. For this reason, if the usage status of the shared facilities is obtained, it is not necessary to go to the shared facilities to check whether the shared facilities are being used. It becomes possible.

[Third Embodiment]
Next, a human detection device 10 according to a third embodiment of the present invention will be described.
In the first and second embodiments described above, a case where status data indicating the presence status and usage status of the section D is delivered from the human detection device 10 in response to a status request from the user terminal 20 is taken as an example. explained. In the present embodiment, notification data indicating the specified presence status or usage status is sent from the human detection device 10 to the user terminal 20 when a preset notification condition regarding the presence status or usage status is satisfied. A case of distribution will be described.

FIG. 9 is a configuration example of the notification condition. Here, a seat ID indicating a detection target, a shared facility ID, notification contents, and a notification destination are registered for each condition ID for identifying the notification condition.
For example, for the condition “J01”, the seat “P11”, that is, “Azbil Taro” is registered as the detection target, and the notification content is registered to notify that “attended”, that is, “Azbil Taro” has returned to her seat. Has been. As the notification destination, user identification information, for example, an e-mail address or the IP address of the user terminal 20 is registered.

  For the condition “J02”, the conference table “C” is registered as a detection target, and is registered to notify that “not available” is set as the notification content. In addition, user identification information, for example, a user's mail address or the IP address of the user terminal 20 is registered as a notification destination.

  The distribution processing unit 18 receives a notification condition from the user terminal 20 and saves it in the storage unit 13, and the notification condition of the storage unit 13 is established when the presence status and usage status of the storage unit 13 are updated. If it is established, if it is established, it has a function of delivering notification data indicating notification contents indicating the presence status or usage status to the user terminal 20 specified by the notification condition. . Notification data may be distributed by mail or message.

  For example, when a notification condition that sets presence or absence regarding the target seat as notification contents is set, the distribution processing unit 18 sets the target specified in the notification condition when the status data indicating the detection status is updated. If the presence status regarding the seat changes and matches the presence or absence specified in the notification content and the notification condition is satisfied, notification data indicating the notification content is sent to the user terminal 20 specified in the notification condition. To deliver.

  In addition, when a notification condition is set that indicates whether the target shared facility can be used or cannot be used, the distribution processing unit 18 is designated by the notification condition when the status data indicating the usage status is updated. When the usage status regarding the target shared facility is usable or unusable specified by the notification content and the notification condition is satisfied, the notification data indicating the notification content is distributed to the user terminal 20 specified by the notification condition.

  At this time, if the detection target registered in the notification condition is a shared facility, it may be determined whether or not the notification condition is satisfied, in the same manner as the use status non-use determination described in the second embodiment. That is, the distribution processing unit 18 determines that all seats provided in the shared facility can be used if no person is detected, and any one of the seats provided in the shared facility can be detected. Is determined to be unavailable.

[Operation of Third Embodiment]
Next, with reference to FIG. 10, operation | movement of the human detection apparatus 10 concerning this Embodiment is demonstrated. FIG. 10 is a sequence diagram illustrating a notification data distribution operation according to the third embodiment.
Here, the notification data distribution operation will be described. The situation data generation operation and the usage situation generation operation are the same as those in FIG. 4 described above, and a detailed description thereof is omitted here.

[Notification data distribution operation]
When the situation data is newly generated by the situation data generation unit 17, the distribution processing unit 18 of the human detection device 10 acquires the situation data from the storage unit 13 (step 300), and sets notification conditions from the storage unit 13. Obtain (step 301).

Next, the distribution processing unit 18 confirms whether or not each condition registered in the notification condition is satisfied based on the situation data (step 302), and sends notification data indicating the notification content registered in the satisfied condition. Then, it is distributed to the user terminal 20 registered as a notification destination under the conditions (step 303).
When the notification content distributed from the human detection device 10 is received, the user terminal 20 displays the received notification content on the screen (step 304), and ends the series of notification data distribution operations.

  FIG. 11 is a screen display example of notification data. FIG. 11A shows a notification example when the condition “J01” in FIG. 9 is satisfied, and the resident “Azbil Taro” of the seat “P11” to be detected is present, that is, in his seat. The return is informed by the notification data. FIG. 11B shows a notification example when the condition “J02” in FIG. 9 is satisfied, and notification that the shared equipment “conference table C” to be detected is available. Notified by data.

[Effect of the third embodiment]
As described above, according to the present embodiment, the distribution processing unit 18 uses the user terminal 20 as a detection target for any seat or common facility in the section, and notifies the presence / absence or availability of the detection target. If the notification condition is received and saved in the storage unit 13 and the status data is updated, the detection status related to the target seat to be detected and the usage status related to the target shared facility specified in the notification condition of the storage unit 13 The notification data indicating the notification content is distributed to the user terminal 20 specified by the notification condition when the presence / absence specified by the notification content or availability becomes available.

  As a result, the presence / absence or availability of an arbitrary detection target is automatically distributed to the user terminal 20 without transmitting a status request regarding the detection status or usage status from the user terminal 20. Become. Therefore, it is possible to greatly reduce the operation burden on the user regarding confirmation of the detection status and usage status.

  In addition, when the common facility is reserved and managed by the reservation system, the human detection device 10 cooperates with the reservation system and automatically reserves the use of the common facility in the reservation system upon detection of the start of use of the common facility. The reservation of the shared facility may be automatically canceled in the reservation system in response to the detection of the end of use of the shared facility. Thereby, the user's reservation operation burden on the reservation system can be greatly reduced.
