  FIG. 1 is a block diagram schematically showing a configuration of a monitoring system 1 according to an embodiment of the present invention. As shown in FIG. 1, the monitoring system 1 includes a difference camera 100 that is an imaging unit, a monitoring device 10, a warning unit 600 that is a warning unit, a regulation unit 610 that is a regulation unit, and a guidance unit 620 that is a guidance unit. . Furthermore, the monitoring apparatus 10 includes an area setting unit 200 that is a setting unit, a trajectory detection unit 300 that is a first detection unit, a stay time detection unit 400 that is a second detection unit, and a determination unit 500 that is a determination unit. ing. The output of the difference camera 100 is connected to the input of the trajectory detection unit 300. The output of the area setting unit 200 is connected to the input of the stay time detection unit 400. The output of the trajectory detection unit 300 is connected to the input of the stay time detection unit 400. The output of stay time detection unit 400 is connected to the input of determination unit 500. The output of the determination unit 500 is connected to the input of the warning unit 600, the input of the restriction unit 610, and the input of the guidance unit 620.

  Here, the monitoring device 10 may be a general-purpose computer system. In that case, as a configuration (not shown), a CPU, a memory, and the like are provided, and the monitoring device 10 realizes the function by executing a program stored in the memory by the CPU.

  Next, the operation of the monitoring system 1 according to the embodiment of the present invention will be described. First, the area setting unit 200 sets at least one attention area in a monitoring area that is substantially equal to the imaging range of the difference camera 100. The setting of the area of interest is output to the stay time detection unit 400 as area setting information S12. The monitoring system 1 uses the attention area to monitor a moving object that is a monitoring target.

FIG. 2 is a flowchart showing a mobile monitoring process performed by the monitoring system 1 according to the embodiment of the present invention. The monitoring system 1 performs the processing shown from step SP100 to step SP150 in each set attention area. Hereinafter, the mobile body monitoring process performed by the monitoring system 1 will be described with reference to FIG.

  First, in step SP100, the trajectory detection unit 300 detects a moving object whose operation is to be monitored in the video included in the output signal S11 output from the difference camera 100. The difference camera 100 is a camera using a device such as a silicon retina that is a moving body sensor that outputs a time difference image, and an image included in the output signal S11 is a difference image obtained by time difference of the imaging range. The trajectory detection unit 300 detects the moving object based on the video that has been subjected to the time difference. In addition, when there are a plurality of moving objects whose operations are to be monitored, the trajectory detection unit 300 may detect a plurality of moving objects at the same time.

  Next, in step SP110, the trajectory detection unit 300 determines whether a moving object has been detected. When the locus detection unit 300 detects a moving body (that is, when the determination result in step SP110 is “YES”), the determination unit 500 performs an operation of step SP120 described later. On the other hand, when the locus detection unit 300 does not detect the moving body (that is, when the determination result in step SP110 is “NO”), steps SP100 and SP110 are performed until the locus detection unit 300 detects the moving body. repeat.

  Next, in step SP120, the determination unit 500 determines whether or not the motion of the moving body detected by the trajectory detection unit 300 matches a predetermined operation. When the movement of the moving body is adapted to the predetermined movement (that is, when the determination result in step SP130 is “YES”), the determination unit 500 determines the determination result information S15 that the movement of the moving body is adapted to the predetermined movement. Is output. On the other hand, when the movement of the moving body does not match the predetermined movement (that is, when the determination result in step SP130 is “NO”), the determination unit 500 does not match the movement of the moving body to the predetermined movement. The determination result information S15 is output.

  When the determination result in step SP130 is “NO” and determination result information S15 indicating that the motion of the moving body does not match the predetermined motion is output from the determination unit 500, the determination result information S15 includes the warning unit 600. And the restriction unit 610. In step SP150, the warning unit 600 warns the moving body to perform a predetermined operation. The restricting unit 610 restricts the moving body from leaving the monitoring area until a predetermined operation is completed. At this time, the determination result information S15 may be input to the guide unit 620. In this case, the guide unit 620 may guide the moving body to a place where a predetermined operation should be performed.

  When the determination result in step SP130 is “YES” and determination result information S15 indicating that the motion of the moving body is adapted to the predetermined motion is output from the determination unit 500, the determination result information S15 is guided to the regulation unit 610. To the unit 620. In step SP140, the restriction unit 610 cancels the restriction when the restriction on the moving body leaving the monitoring area has been performed. In addition, the guiding unit 620 performs guidance in the direction in which the moving body should move next.

  Further, the operation determination performed in step SP120 will be described in detail. FIG. 3 is a flowchart showing processing of the monitoring system 1 in operation determination. First, in step SP200, based on the time difference video output from the difference camera 100, the trajectory detection unit 300 detects a moving trajectory in which the mobile body detected in step SP110 moves with time. The trajectory detection unit 300 outputs the travel trajectory information S13 including information on the travel trajectory to the stay time detection unit 400.

Next, in step SP210, the stay time detection unit 400 determines whether or not the mobile body has entered the attention area based on the input movement trajectory information S13 and the area setting information S12 input from the area setting unit 200. judge. When the moving body enters the attention area (that is, when the determination result in step SP210 is “YES”), the staying time detection unit 400 starts measuring the staying time during which the moving body stays in the attention area. On the other hand, when the moving object does not enter the attention area and does not advance to other attention areas, the monitoring system 1 ends the operation determination and ends the monitoring of the moving object.

  Next, in step SP220, the stay time detector 400 determines whether or not the mobile object has left the area of interest within a predetermined time based on the input movement trajectory information S13. When the mobile object has left the attention area (that is, when the determination result in step SP220 is “YES”), in step SP230, the stay time detection unit 400 detects the stay time in which the mobile object stayed in the attention area. . On the other hand, when the moving object has not left the area of interest (that is, when the determination result in step SP220 is “NO”), the staying time detection unit 400 performs the process of step SP250 described later.

  FIG. 4 is a diagram schematically showing the relationship between the movement trajectory of the moving object and the attention area. In FIG. 4, a point where the moving locus L1 of the moving body enters the attention area F1 is a point P1, and a point where the moving locus L1 leaves the attention area F1 is a point P2. In step SP230, when the stay time detection unit 400 detects the stay time in which the mobile object stays in the attention area, the elapsed time required to move from the point P1 to the point P2 is detected as the stay time of the mobile object. Then, stay time detection section 400 outputs moving body stay information S14 including the detected stay time and the movement trajectory to determination section 500.

  Next, in step SP240, the determination unit 500 determines whether or not the operation performed by the mobile body is suitable for a predetermined operation based on the input mobile body stay information S14. In this determination, the trajectory of the moving body and the staying time are used, and it is determined whether or not each of the attention areas has stayed in the attention area for a predetermined time required for a predetermined operation. For example, if the time required for the predetermined operation is 30 seconds, it is determined that the predetermined operation is performed if the predetermined operation is performed if the user stays in the attention area for 30 seconds or more. On the other hand, if the moving object stays in the attention area for less than 30 seconds, it is determined that the predetermined operation has not been met. At this time, if the user stays in the area of interest for 30 seconds or more, but stays in the area of interest for a period of time that significantly exceeds the predetermined time (for example, a time exceeding 2 minutes), the abnormal action is determined as the abnormal action. Judge that it does not conform. These determination results are output from the determination unit 500 as determination result information S15.

  Also, if the determination result in step SP220 is “NO” and it is not possible to detect the exit of the moving object from the attention area (for example, if the exit is not performed after 5 minutes), in step SP250 The determination unit 500 determines that the abnormal action is not suitable for the predetermined operation. This determination result is output from the determination unit 500 as determination result information S15.

  Accordingly, the monitoring system 1 can determine whether or not the operation performed by the moving body is a predetermined operation by monitoring the moving body shown in steps SP100 to SP150. In addition, when a plurality of attention areas are set, the monitoring system 1 comprehensively determines the actions performed in each of the attention areas, and a continuous operation across the plurality of attention areas is a predetermined continuous operation. It can also be determined whether or not.

As described above, the monitoring system 1 detects the movement trajectory of the moving object and the staying time in the attention area based on the video imaged by the difference camera 100, and is the moving object performing a predetermined operation? It can be determined whether or not. Therefore, it can be determined by simple logic whether the moving body is performing a predetermined operation. As a result, according to the monitoring system 1, when the moving object to be monitored is not performing a predetermined operation, appropriate measures such as warning by the warning unit 600, regulation by the regulation unit 610, and guidance by the guidance unit 620 are taken. Using a relatively low-cost and small-scale system, real-time processing can be performed.

  In addition, since the movement trajectory is detected using the time-difference video by the difference camera 100 and the motion determination is performed using the movement trajectory, information on an object that does not move on the image is not used. Therefore, the amount of information to be used is small, and the load on information processing can be further reduced. In addition, since the output of the difference camera 100 is a time difference image, a face or characters of a person with little movement is not clearly captured. Therefore, an image related to personal information is not imaged, and it is possible to monitor an operation in consideration of personal information.

  In the embodiment of the present invention, it is not necessary to have one camera for imaging the monitoring area, and a plurality of cameras may be used. When there are a plurality of cameras, by partially overlapping the imaging ranges of the respective cameras, it is possible to detect the movement locus of the moving body as one continuous locus even if the cameras to be imaged are changed.

<First Embodiment>
The first embodiment of the present invention is a monitoring system 1 that monitors whether or not an operator has performed hand washing in a food factory or canteen that requires hygiene management by hand washing. In this case, the moving body to be monitored is a worker in a food factory or canteen. FIG. 5 is an example of setting the attention area in the monitoring area where the hand washing operation is monitored. The area setting unit 200 includes, in the monitoring area, an attention area F2 having an entrance / exit, an attention area F3 having a hand-washing area, and an attention area F4 in which a gate G1 that separates a workplace requiring hygiene management from the outside is installed. Three attention areas are set.

  First, when an operator of the food factory enters the factory, the food factory enters the attention area F2 set as an entrance. At this time, the trajectory detection unit 300 of the monitoring system 1 detects the worker and starts monitoring the moving object in the attention area F2. The predetermined operation monitored in the attention area F2 is “entry into the factory”. The trajectory detection unit 300 detects that the moving trajectory of the moving body has entered the attention area F2, and the staying time detection unit 400 calculates the staying time (for example, a staying time of 0.5 seconds or more) of the moving body in the attention area F2. If it is detected, the determination unit 500 determines that a predetermined operation “entering the factory” has been performed. When this determination is made, determination result information S15 output from the determination unit 500 is input to the guidance unit 620.

  Next, in response to a predetermined operation “entering the factory”, the guiding unit 620 guides the operator to the next operation to be performed. Specifically, an arrow like the guidance display C1 in FIG. 5 may be displayed so that it is easy for the operator to know which direction to go next. Moreover, when the monitoring system 1 has an audio output function such as a speaker, guidance may be performed by audio output.

  Next, when the worker heads for the hand washing place according to the guidance such as the guidance display C1, the movement locus of the worker detected by the locus detection unit 300 enters the attention area F3. At this time, the stay time detection unit 400 detects the stay time in which the worker stayed at the hand washing area. For example, when the hand washing is required for 30 seconds or more according to the sanitary management standard of the food factory, the predetermined time for determining the predetermined operation in the determination unit 500 can be set to 35 seconds. That is, when the worker stays in the attention area F3 for less than 35 seconds at the hand washing place, the determination unit 500 determines that the hand washing is not performed or the hand washing is insufficient.

If an operator who does not wash his hands or has insufficient hand washing leaves the attention area F3 and tries to enter the attention area F4 following the work place requiring hygiene management (to this attention area F4) The determination of approach can also be performed based on the movement trajectory detected by the trajectory detection unit 300), and the monitoring system 1 performs warning and regulation by the warning unit 600 and the regulation unit 610. The warning performed by the warning unit 600 may be a warning text displayed on a display device, or may be a voice warning message or a warning sound. In addition, the regulation performed by the regulation unit 610 is such that the person who does not wash hands or who does not have enough hand washing does not enter the workplace where hygiene management is required so that the gate G1 is not opened. Good. FIG. 6 is a diagram illustrating an example of warning by the monitoring system 1. In FIG. 6, the warning unit 600 includes a warning display D1 that issues a warning on the gate G1 side.

  In addition, when an operator who has entered from the attention area F2 that is the entrance / exit attempts to enter the attention area F4 that requires hygiene management without entering the attention area F3 that has the hand-washing area, the determination unit 500 The operator's motion is determined by integrating the motion determination in each area of interest. In this case, since the determination in the attention area F3 is not performed, the determination unit 500 determines that the worker is not performing a predetermined operation of hand washing. Then, the warning unit 600 issues a warning that hand washing has not been completed, and the regulation unit 610 closes the gate G1 to regulate the worker. Further, the guiding unit 620 guides the worker to the attention area F3 that is a hand washing place.

  When the worker who has entered from the attention area F2 that is the entrance / exit stays in the attention area F3 that is the hand-washing area for a predetermined staying time and no abnormal motion that does not conform to the predetermined motion is detected, the monitoring system 1 The determination unit 500 determines that the worker appropriately performed hand washing. At this time, the regulation by the regulation unit 610 (regulation such as the gate G1 in FIG. 5) is released, and the operator is guided to the work place by the guidance unit 620 (by guidance display such as C2 in FIG. 5).

  As described above, if the monitoring system 1 of the first embodiment is used, the operator's hand washing operation is monitored in a place where hygiene management by hand washing is necessary, and it is determined that the worker is not performing hand washing appropriately. In such cases, warnings and regulations can be given, and guidance can be provided so that workers can wash their hands. Hygiene management by the monitoring system 1 is not limited to food factories, and can be used for medical treatment and countermeasures against infectious diseases.

<Second Embodiment>
In the second embodiment of the present invention, the monitoring system 1 includes a camera 700 that is recording means for recording information capable of identifying a moving object to be monitored and another moving object, and a moving object obtained by the camera 700. And a recording unit 800 for recording information such as images. FIG. 7 is a block diagram schematically showing a configuration in the second embodiment of the present invention. FIG. 8 is a diagram schematically illustrating an installation example of the camera 700 that captures a moving object as an identifiable video.

  As in the monitoring system shown in the first embodiment, when the restriction unit 610 restricts the movement of the moving object by the gate G1, the camera 700 can capture the appearance of the moving object that is going through the gate G1. is set up. When a moving body that is not performing a predetermined operation in the area of interest attempts to pass through the gate G1, the determination unit 500 determines that the moving body is not performing a predetermined operation. At this time, the determination unit 500 locks the gate G <b> 1 so as not to open due to the restriction of the restriction unit 610, and sends a command to the camera 700 to image the moving body. Images captured by the camera 700 are recorded in the recording unit 800.

  Accordingly, by leaving a moving body that is not performing a predetermined operation as an image by the camera 700, it is possible for the monitoring side to grasp which moving body has not performed the predetermined operation. In addition, when a warning is given when a predetermined operation is not performed, the captured image is displayed on the mobile body itself, thereby clearly indicating that the monitoring is being performed and enhancing the warning effect. It becomes possible.

<Third Embodiment>
In the third embodiment of the present invention, an identification device such as a non-contact type ID tag is attached to a moving body in advance, and the monitoring system 1 includes a moving body to be monitored and other moving bodies. The ID tag reader 750 is installed as a recording means for recording information that can identify the ID. In addition, the monitoring system 1 includes a recording unit 800 for recording ID information read by the reading device 750. FIG. 9 is a block diagram schematically showing a configuration in the third embodiment of the present invention. FIG. 10 is a diagram schematically illustrating an installation example of the reader 750 for the non-contact ID tag.

  The moving body monitored by the monitoring system 1 according to the third embodiment is a factory worker, for example, and a contactless ID tag is embedded in advance in each worker's name tag or uniform. When the gate G1 to be passed by the worker is installed as in the monitoring system shown in the first embodiment, the reading device 750 is installed in front of the gate G1, and the worker (or the worker passing through the gate G1) (or The ID information of the worker who tried to pass is read, and information such as the ID and the passing time is recorded in the recording unit 800.

  Therefore, according to the monitoring system 1 which concerns on 3rd Embodiment, identification of each moving body is attained with a non-contact-type ID tag. Therefore, a different monitoring system can be taken for each moving body, and the contents of monitoring, regulation, and guidance can be changed for each moving body. It is also possible to obtain information such as the number of times of entry / exit and the frequency of performing an operation that does not match the predetermined operation.

<Fourth Embodiment>
The fourth embodiment of the present invention is a monitoring system using a CCD camera 150, which is a camera that does not perform time difference output as an imaging means for detecting a moving object. In this case, since the camera itself does not output the time-difference video, the monitoring system 10 performs image processing using the video that is not time-difference output from the CCD camera 150 and detects the movement locus of the moving body. FIG. 11 shows an example of a schematic configuration of the fourth exemplary embodiment of the present invention. At this time, the monitoring device 10 is a general-purpose computer system.

  The image processing function for performing the time difference of the video included in the monitoring device 10 is realized by executing a program 955 called from the memory 950 by the CPU 900. At this time, the movement trajectory detection function, the stay time detection function, and the operation determination function, which are other functions of the monitoring device 10, are also realized by the CPU 955 executing the program 955 called from the memory 950.
