  [Configuration and basic operation]

  FIG. 1 is a diagram showing a configuration of a hand-washing monitor according to an embodiment of the present invention.

  Referring to FIG. 1, a hand-washing monitor 101 includes a touch panel PC (personal computer) 1, a camera 2, Patlite (registered trademark) 3, and a hub (HUB) 5.

  The camera 2 is installed at a position overlooking the hand-washing sink 61 to which the faucet 62 is attached, captures an image including the hand-washing sink 61, and outputs the captured image to the touch panel PC 1 via the hub 5. This image may be a still image or a moving image.

  For example, the camera 2 is disposed obliquely with respect to the hand-washing sink 61 instead of directly above the hand-washing sink 61. Thereby, the operator's hand washing operation in the hand washing sink 61 can be photographed in detail.

  The touch panel PC1 is a personal computer with a touch panel display. The touch panel PC1 performs predetermined image processing on the image received from the camera 2 to determine whether or not the person H has performed a handwashing operation in the handwashing sink 61.

  The touch panel PC1 turns on and off the patrol light 3 and outputs a message to its own screen based on the result of the image processing.

  The touch panel PC1 records an image received from the camera 2 and outputs log information to an administrator terminal (management apparatus) 151 such as a personal computer.

  FIG. 2 is a diagram showing an example of an application area of the hand-washing monitor according to the embodiment of the present invention.

  Referring to FIG. 2, hand-washing monitor 101 is installed, for example, in room R1 next to room R2, which is a kitchen.

  The room R1 has an entrance D1 for an operator to enter and exit from the outside, and an entrance D2 for entering and exiting the room R2. The worker normally enters the room R1 from the entrance D1 and performs hand washing in the hand-washing sink 61, and then enters the room R2 serving as a cooking place from the entrance D2. The camera 2 is installed, for example, in a position overlooking the hand-washing sink 61 and the doorway D1.

  In addition, a soap 71, a towel 72, and a disinfecting alcohol 73 are provided on the hand-washing sink 61 side.

  When a plurality of hand-washing sinks 61 are installed in the room R1, or when there are a plurality of entrances and exits of the room R1, a plurality of hand-washing monitors 101 may be provided in the room R1, or a plurality of cameras 2 may be provided. May be.

  FIG. 3 is a diagram showing an image taken by the hand-washing monitor according to the embodiment of the present invention.

  Referring to FIG. 3, touch panel PC1 sets an area in the vicinity of doorway D1 of room R1 as monitoring area AR1 in the image captured by camera 2.

  And touch panel PC1 detects the approach of the person to monitoring area AR1 based on the image which the camera 2 image | photographed by the method similar to the monitoring apparatus of patent document 2, for example.

  Further, the touch panel PC1 sets an area near the hand-washing sink 61 in the image taken by the camera 2 as the monitoring area AR2.

  And touch panel PC1 detects the approach of the person to monitoring area AR2 based on the image which the camera 2 image | photographed by the method similar to the monitoring apparatus of patent document 2, for example.

  Further, the touch panel PC1 detects that, for example, the hand of the intruder is moving in a predetermined pattern in the monitoring area AR2 based on the image taken by the camera 2, and measures this operation time. For example, the touch panel PC1 detects that an intruder's hand is moving in a predetermined pattern by extracting feature points of the image by shape, color, brightness, and the like, and performing edge detection. Here, the touch panel PC1 can exclude the time during which the intruder's hand is not moving from the measurement time when the intruder has a conversation with another person and the hand moves intermittently.

  FIG. 4 is a diagram illustrating an operation in which the hand-washing monitor according to the embodiment of the present invention detects a human hand and its operation. FIG. 4 schematically shows an enlarged image of the monitoring area AR2 shown in FIG.

  Referring to FIG. 4, touch panel PC 1 detects the position of intruder's hand G based on the image taken by camera 2, and measures the operating time of the detected hand G. The touch panel PC1 detects the intruder's hand G by edge detection and pattern matching, for example.

  The touch panel PC1 stores in advance the positions of the soap 71, the towel 72, and the disinfecting alcohol 73 in the monitoring area AR2. That is, touch panel PC1 sets monitoring areas AR3, AR4, and AR5 that include soap 71, towel 72, and disinfecting alcohol 73, respectively, within monitoring area AR2.

  And touch panel PC1 detects the presence or absence and approach order of the approaching person's hand G to monitoring area AR3, AR4, AR5.

  Note that only one of the monitoring areas AR3, AR4, and AR5 may be set as the monitoring area for detecting the entry of the hand G, or four or more including other areas may be set. That is, not only the soap 71, the towel 72, and the disinfecting alcohol 73, the hand-washing sink 61 is provided with other hand-washing items such as a hand-washing brush, and the touch panel PC1 includes a hand-washing brush and the like of an intruder's hand. The structure which detects further approach to the monitoring area may be sufficient.

  The hand-washing monitor 101 performs status notification to an intruder using, for example, an external output device based on the image taken by the camera 2.

  Specifically, the hand-washing monitor 101 uses a patrol light 3 that displays a plurality of colors, that is, lights or blinks.

  For example, the hand-washing monitor 101 turns on the patrol light 3 in yellow when a person enters the monitoring area AR2, turns on the patrol light 3 in green when the invader completes the hand-washing operation according to a predetermined rule, When the intruder violates a predetermined rule, such as when the hand washing time is short, the patrol light 3 is lit in red. In addition, the hand-washing monitor 101 blinks the patrol light 3 in yellow when the human H enters the monitoring area AR2 and there is no movement of the intruder.

  The hand-washing monitor 101 uses the screen of the touch panel PC1. For example, the hand-washing monitor 101 displays the hand washing time of the intruder, displays “OK” when the instructor completes the hand-washing operation according to a predetermined rule, and skips the procedure and the hand washing time is short. If the rule is violated, a message prompting re-execution is displayed.

  In addition, since an operator such as a cafeteria usually wears a mask and a hat, it is difficult to specify an individual only with an image taken by the camera 2. For this reason, hand-washing monitor 101 performs personal recording using touch panel PC1, for example.

  Specifically, the name of the worker who enters the room R2 is registered in advance in the touch panel PC1.

  Then, the touch panel PC1 is installed in the vicinity of the hand-washing sink 61, a name list is displayed on the display of the touch panel PC1, and the operator can press the name on the display. The operator then presses his name on the display before hand washing.

  This does not force handwashers to do more than traditional acts. It is desirable to record hand-washing actions according to HACCP (Hazard Analysis and Critical Control Point) standards. Normally, hand-washers record personal names on a recording sheet (form) before hand-washing.

  That is, in the hand-washing monitor 101, the recording action by the hand-washing person is replaced by pressing the touch panel.

  The hand-washing monitor 101 accumulates information for supervisors. That is, the touch panel PC1 stores hand washing action records and videos. The handwashing record and video can be confirmed by the supervisor.

  Specifically, the touch panel PC1 outputs log information such as hand-washing action records and videos to the administrator terminal 151. The administrator terminal 151 creates a form based on the log information received from the touch panel PC1.

  FIG. 5 is a diagram illustrating an example of a form screen created by the administrator terminal and used by the supervisor.

  Referring to FIG. 5, this form shows the correspondence between the monitoring location, the date of occurrence of the event, the time of occurrence of the event, the judgment result of the hand washing operation, the hand washing time, and the operator name. For example, when an administrator double-clicks each line of a form on the screen, a corresponding video is displayed on the screen.

  FIG. 6 is a functional block diagram of the hand-washing monitor according to the embodiment of the present invention.

  Referring to FIG. 6, hand-washing monitor 101 includes imaging unit 11, intruder detection unit 12, body part detection unit 13, operation time measurement unit 14, operation determination unit 15, presentation unit 16, and part. An entry detection unit 17, an indoor entry detection unit 18, an intruder information acquisition unit 19, a personal information output unit 20, and an original information output unit 21 are provided.

The imaging unit 11 corresponds to the camera 2 shown in FIG. 1, and the presentation unit 16 corresponds to the screen of the patrol light 3 and the touch panel PC1 shown in FIG.

  The intruder detection unit 12 detects a person entering the monitoring area AR2 based on the image captured by the imaging unit 11.

  Based on the image photographed by the photographing unit 11, the body part detection unit 13 detects a target part that is a part or all of the hand-washing part of an intruder who has entered the monitoring area AR2. Here, the target portion is, for example, the entire hand, and may include a wrist and an arm in addition to the entire hand. Further, the target portion may be a part of a hand, such as a finger or the back of a hand.

  The operation time measurement unit 14 measures the operation time of the target part detected by the body part detection unit 13 based on the image captured by the imaging unit 11.

  Based on the operation time measured by the operation time measurement unit 14, the operation determination unit 15 determines whether the instructor has performed a prescribed hand washing operation.

  More specifically, the part entry detection unit 17 detects the entry of the target part into the partial area in the monitoring area AR2, that is, the monitoring areas AR3, AR4, and AR5, from the image.

  Then, the motion determination unit 15 determines whether or not the instructor has performed a prescribed hand-washing operation based on the detection result by the part entry detection unit 17 and the operation time measured by the operation time measurement unit 14.

  For example, the part entry detection unit 17 detects whether or not the target part has entered the plurality of partial areas AR3, AR4, and AR5 in the monitoring area AR2 and the order of entry.

  Then, based on the presence / absence and order of entry detected by the part entry detection unit 17 and the operation time measured by the operation time measurement unit 14, the operation determination unit 15 determines whether the instructor has performed a prescribed hand-washing operation. Determine whether or not.

  The photographing unit 11 photographs an image including the entrance D1.

  Based on the image captured by the imaging unit 11, the indoor entry detection unit 18 detects whether or not a person has entered the entrance D1 and whether the entry to the entrance D1 is the exit direction or the entrance direction.

  Then, the operation determination unit 15 determines whether or not the instructor has performed a prescribed hand-washing operation based on the detection result by the indoor entry detection unit 18 and the operation time measured by the operation time measurement unit 14.

  In addition, the presentation unit 16 presents the intruder information regarding the hand washing operation to the intruder.

  Further, the intruder information acquisition unit 19 receives an individual specifying operation by the intruder, for example, a pressing operation on the display of the touch panel PC1, and acquires information on the intruder.

  Then, the personal information output unit 20 outputs the information on the intruder acquired by the intruder information acquiring unit 19 to the manager terminal 151 via the hub 5.

  The photographing unit 11 performs photographing and recording of a moving image in the monitoring area AR2. Then, the original information output unit 21 uses the detection result and the operation time measurement by the body part detection unit 13 as information to be used as a source for creating management information indicating the correspondence relationship between the intruder and the information on the hand washing operation in the administrator terminal 151. The operation time measured by the unit 14, the determination result by the operation determination unit 15, and the moving image shot and recorded by the shooting unit 11 are output to the administrator terminal 151.

[Operation]
Next, the operation when the hand washing monitor according to the embodiment of the present invention performs hand washing monitoring will be described.

  The touch panel PC 1 in the hand-washing monitor 101 reads out and executes each step of the following flowcharts from a memory (not shown). This program can be installed externally. The installed program is distributed in a state stored in a recording medium, for example.

  FIG. 7 is a flowchart defining an operation procedure when the hand washing monitor according to the embodiment of the present invention performs the hand washing monitoring process.

  With reference to FIG. 7, first, the indoor entry detection unit 18 monitors the approach of a human to the monitoring area AR <b> 1 based on the image captured by the imaging unit 11.

  When detecting that a person has entered the monitoring area AR1 from outside the room R1 (YES in step S1), the indoor entry detection unit 18 notifies the intruder detection unit 12 of the detection.

  Next, the intruder detection unit 12 receives a notification from the indoor entry detection unit 18 and monitors the entry of a human into the monitoring area AR2 based on the image captured by the imaging unit 11. When the person enters the monitoring area AR2 within a predetermined time after receiving the notification (YES in step S2), the intruder detection unit 12 notifies the body part detection unit 13 that the entry has occurred. Notice.

  Next, the body part detection unit 13 receives the notification from the intruder detection unit 12 and performs a process for detecting the hand of the intruder based on the image captured by the imaging unit 11 (step S3).

  Next, when the body part detection unit 13 detects the hand of the intruder, the body part detection unit 13 notifies the operation time measurement unit 14 and the part entry detection unit 17 of the detection, and lights the patrol light 3 that is the presentation unit 16 in yellow. (Step S4).

  Next, the original information output unit 21 starts recording the video imaged by the imaging unit 11 (step S5).

  Next, the operation time measurement unit 14 receives the notification from the body part detection unit 13, measures the operation time of the intruder's hand, and notifies the operation determination unit 15 of the measurement result (step S6).

  In addition, the part entry detection unit 17 receives the notification from the body part detection unit 13 and detects the presence and the order of entry of the intruder's hand in the monitoring area AR2 into the monitoring areas AR3, AR4, and AR5, The detection result is notified to the operation determination unit 15 (step S6).

  Next, the motion determination unit 15 moves the intruder's hand in the monitoring area AR2 for a predetermined time or more (YES in step S7) and the intruder's hand enters the monitoring areas AR3, AR4, and AR5 in this order. (YES in step S8), it is determined that the intruder has performed the correct hand washing operation (step S9), and the patrol light 3 is lit in green (step S10).

  Next, the original information output unit 21 finishes recording the video imaged by the imaging unit 11, updates the log information based on the video image and the hand washing action record, and outputs the log information to the administrator terminal 151. Here, the hand washing action record includes the detection result and detection date and time of the indoor entry detection unit 18, the intruder detection unit 12 and the body part detection unit 13, the measurement time of the operation time measurement unit 14, the determination result of the operation determination unit 15, and the like. (Step S11).

  Next, the intruder detection unit 12 monitors the exit of the person from the monitoring area AR2 based on the image captured by the imaging unit 11. Then, when the person leaves the monitoring area AR2 (step S12), the intruder detection unit 12 turns off the patrol light 3 (step S13).

  On the other hand, when the intruder detection unit 12 receives the notification of entering the monitoring area AR1, the operation determining unit 15 does not enter the monitoring area AR2 within a certain time (NO in step S2). When the intruder's hand has not moved more than the specified time before leaving the monitoring area AR2 (NO in step S7), or when the intruder's hand has not entered the monitoring areas AR3, AR4 and AR5 in order. (NO in step S8), it is determined that the intruder did not perform the correct hand washing operation (step S14), and the patrol light 3 is lit red (step S15).

  Next, the original information output unit 21 finishes recording the video imaged by the imaging unit 11, updates the log information based on the video image and the hand washing action record, and outputs the log information to the administrator terminal 151. (Step S11).

  Next, the intruder detection unit 12 monitors the exit of the person from the monitoring area AR2 based on the image captured by the imaging unit 11. Then, when the person leaves the monitoring area AR2 (step S12), the intruder detection unit 12 turns off the patrol light 3 (step S13).

  The intruder detection unit 12 turns on the patrol light 3 in red because the intruder's hand has not moved for a predetermined time or more before the intruder leaves the monitoring area AR2 (NO in step S7). Since the person has left the monitoring area AR2, the patrol light 3 is immediately turned off (step S13).

  By the way, in the method of patent document 1, since the said time cannot be specified, it cannot judge based on the total time of a hand-washing act. Moreover, in the method described in Patent Document 1, it is necessary to install an electronic soap applicator, a water faucet, an air towel, and a sterilizer, which is expensive. Moreover, with the technique described in Patent Document 2, it is difficult to determine whether, for example, an operator located in front of the sink is standing or washing his / her hand.

  On the other hand, in the hand-washing monitor according to the embodiment of the present invention, the intruder detection unit 12 detects the human approach to the monitoring area AR2 in the image captured by the imaging unit 11. The body part detection unit 13 detects from the image a target portion that is a part or all of the hand-washing portion of an intruder who has entered the monitoring area AR2. The operation time measurement unit 14 measures the operation time of the target portion detected by the body part detection unit 13. Then, based on the operation time measured by the operation time measurement unit 14, the operation determination unit 15 determines whether or not the instructor has performed a prescribed hand washing operation.

  As described above, in the hand-washing monitor according to the embodiment of the present invention, for example, an algorithm for discriminating a human hand-washing action using image processing is added to the method using the monitoring device described in Patent Document 2. That is, instead of the staying time in the intruder's monitoring area AR2, the time during which the intruder is moving is measured. Thereby, since both a human stay and a human action can be monitored and a hand-washing time can be measured correctly, the presence or absence of hand-washing can be determined correctly. Further, by measuring the operation time of the target portion such as the hand of the intruder, a more accurate hand washing time can be detected.

  Therefore, the hand washing monitor according to the embodiment of the present invention can accurately determine the hand washing operation of the subject with a low-cost configuration.

  That is, the hand-washing monitor according to the embodiment of the present invention is not limited to the configuration including all the functional blocks shown in FIG.

  For example, the hand-washing monitor 101 may be configured without the photographing unit 11. In this case, the hand washing monitor 101 acquires an image of the monitoring area from the outside of the hand washing monitor 101.

  In addition, the hand-washing monitor 101 does not include the presentation unit 16, the part entry detection unit 17, the indoor entry detection unit 18, the intruder information acquisition unit 19, the personal information output unit 20, and the original information output unit 21. It may be a configuration.

  Moreover, in the hand-washing monitor which concerns on embodiment of this invention, the site | part approach detection part 17 detects the approach of the said target part to the partial area in monitoring area AR2 from an image. Then, the motion determination unit 15 determines whether or not the instructor has performed a prescribed hand-washing operation based on the detection result by the part entry detection unit 17 and the operation time measured by the operation time measurement unit 14.

  With such a configuration, it is possible to detect whether or not the intruder has used a predetermined hand-washing product, for example, so that the hand-washing operation can be determined more accurately.

  Further, in the hand-washing monitor according to the embodiment of the present invention, the part entry detection unit 17 detects the presence / absence and the order of entry of the target part into the plurality of partial areas in the monitoring area AR2. Then, based on the presence / absence and order of entry detected by the part entry detection unit 17 and the operation time measured by the operation time measurement unit 14, the operation determination unit 15 determines whether the instructor has performed a prescribed hand-washing operation. Determine whether or not.

  With such a configuration, it is possible to detect whether or not the intruder has performed hand washing according to the procedure, so that the hand washing operation can be determined more accurately.

  Further, in the hand-washing monitor according to the embodiment of the present invention, the indoor entry detection unit 18 images whether or not a person has entered the entrance D1 and whether the entry to the entrance D1 is the exit direction or the entrance direction. Detect from. Then, the operation determination unit 15 determines whether or not the instructor has performed a prescribed hand-washing operation based on the detection result by the indoor entry detection unit 18 and the operation time measured by the operation time measurement unit 14.

  As described above, the configuration in which the vicinity of the entrance D1 of the room R1 is set as the monitoring area AR1, and when the worker moves to another place without entering the monitoring area AR2 after entering the room R1, that is, the hand An alarm or the like can be output by detecting a case of moving to another place without washing. In addition, when the operator enters the monitoring area AR2 for purposes other than hand washing, the hand washing monitor 101 can be prevented from outputting an alarm or the like by mistake.

  In the hand-washing monitor according to the embodiment of the present invention, the monitoring area AR2 and the entrance D1 are included in one image captured by the imaging unit 11.

  As described above, with the configuration in which the monitoring area AR2 and the entrance D1 are included in one image, it is not necessary to provide two photographing units, and the configuration can be simplified.

  Moreover, in the hand-washing monitor which concerns on embodiment of this invention, the presentation part 16 presents the intruder's information regarding a hand-washing operation to the said intruder.

  By presenting such information, it is possible to prompt an instructor to perform a hand washing action.

  Moreover, in the hand-washing monitor which concerns on embodiment of this invention, the intruder information acquisition part 19 receives the individual specific operation by an intruder, and acquires the information of an intruder.

  Thereby, it is possible to reduce the act of filling the hand-washing record sheet by the hand-washing person, and to reduce the burden on the operator. In addition, since the operator does not touch the writing instrument after hand washing, hygiene management can be more thorough.

  Moreover, in the hand-washing monitor according to the embodiment of the present invention, the photographing unit 11 photographs a moving image in the monitoring area AR2. Then, the original information output unit 21 uses the detection result and the operation time measurement by the body part detection unit 13 as information to be used as a source for creating management information indicating the correspondence relationship between the intruder and the information on the hand washing operation in the administrator terminal 151. The operation time measured by the unit 14, the determination result by the operation determination unit 15, and the moving image shot by the shooting unit 11 are output to the administrator terminal 151.

  In this way, the configuration that enables the creation of management information such as forms can improve the efficiency of the supervisor's work.

  The above embodiment should be considered as illustrative in all points and not restrictive.
