Description

  The present invention relates to a notification device that detects and reports the occurrence of an emergency such as a burglary, and more particularly to a notification device that does not require operation of a notification button or the like.

Conventionally, as a notification device for a user such as a store or an office to notify an emergency such as a burglary to the outside, a remote monitoring center displays an image captured by a monitoring camera together with an emergency signal by operating a so-called emergency button. What is sent out to is widely known.
Although this type of reporting device is based on the user's voluntary operation, it rarely reports an emergency situation accidentally, but when an emergency such as a burglary occurs, the operation of the emergency button is prevented by the burglary. The user may be upset and forget to operate the emergency button, and there is a problem that the certainty of the notification is lacking.

  In addition, the person who engages in the delivery of cash in the face of the customer operates a notification function to the police etc. that is attached to the lower part of the counter as a detour because the perpetrator for the purpose of robbery possesses weapons etc. Doing so may irritate the perpetrator and cause injury. As a countermeasure against such a problem, Patent Document 1 includes an imaging unit, an abnormality occurrence recognition unit, and an abnormality occurrence notification unit, recognizes the occurrence of an abnormality using image data captured by the imaging unit, and when an abnormality occurs. In an active surveillance camera that notifies the restraint organization of the occurrence of an abnormality, a frame memory that stores a plurality of image frames, and a “person” component is extracted from the image data using the plurality of image frames. An abnormality occurrence recognizing means that extracts the head and both hands from the components and recognizes that both hands are placed above or on the head and recognizes the occurrence of an abnormality, and an abnormality occurrence notification unit when the occurrence of the abnormality is recognized An alarm device having alarm output means for operating an alarm and notifying the occurrence of an abnormality to the outside is disclosed.

JP 2002-35459 A

  According to the reporting device proposed in Patent Document 1, it is possible to report the occurrence of an emergency such as a burglary to the outside while eliminating the need for an emergency button operation by the user. Both convenience and certainty of reporting are possible. Can be improved.

  However, for example, the posture of placing a hand on the head for a predetermined time is a posture that can occur other than when a burglary occurs. If only such a posture is detected and reported, there is a possibility that many malfunctions occur. As a result, the load on the monitoring center that receives the notification increases, and the reliability of the notification device decreases.

  Also, for example, in a 24-hour store such as a convenience store, robbery cases are concentrated between 2 am and 5 am. In addition, there are no other customers in the store and there are one or two store clerks.

  The present invention has been made in view of the above-described problems.When a predetermined posture is detected and an occurrence of an emergency is reported, the posture is detected at a time other than the occurrence of the emergency to detect that an emergency has occurred. The purpose is to propose a notification device that improves the reliability by reducing judgment.

  In order to achieve the above object, a notification device according to the present invention includes an image acquisition unit that acquires an image of a monitoring area, a posture detection unit that detects a posture of a person from the acquired image information, When a storage unit that stores a predetermined posture and a posture detected by the posture detection unit coincide with a posture stored in the storage unit, it is determined whether an emergency call is necessary based on the burglary occurrence factor. A reporting necessity determination unit and a reporting unit that performs reporting according to a determination result of the reporting necessity determination unit.

  As a result, when the clerk takes a predetermined posture, the reporting device determines whether or not reporting is necessary depending on the situation in which the burglary occurs, so it is possible to prevent reporting by mistake other than during an emergency. .

  In the notification device of the present invention, the burglary occurrence state factor is the number of people in the store, and the notification necessity determination unit determines that an emergency call is necessary when the number of people in the store is equal to or less than a predetermined number.

  Thereby, when the monitoring object is crowded with the store visitor or the like, it is possible to prevent erroneous notification due to the attitude of the store clerk or the store visitor.

  Further, in the notification device of the present invention, the burglary occurrence factor is a time zone, and the notification necessity determination means determines that an emergency notification is necessary in the case of a late night time zone.

  According to the present invention, when a predetermined posture taken at the time of occurrence of an emergency situation is detected, an emergency call is made when the number of people in the night time zone or in the store is less than a predetermined number of people, so there is little risk of burglary. It can prevent reducing false reports in the situation.

It is the schematic which shows the whole structure of the notification system by the notification apparatus of this invention. It is a block diagram which shows the structure of the notification apparatus of this invention. It is a flowchart which shows the monitoring process of the notification apparatus of this invention.

Embodiments of the present invention will be specifically described below with reference to the drawings.
In the present embodiment, a case where a sales office such as a financial institution or a store is a monitoring target, and a store area and a cashier counter area are provided as monitoring areas to be monitored, the scope of the present invention is described here. It is not limited to.

FIG. 1 is a configuration diagram showing a notification system 1 using the notification device of the present invention.

These security sensors 7 are connected to a LAN connecting the reporting device 4 and the monitoring camera 3.

  The monitoring camera 3 is a monitoring unit that generates monitoring information of the monitoring area 2. The surveillance camera 3 stores a camera number for identifying each surveillance camera 3 in advance, and an image signal input from the image sensor is transmitted at a predetermined photographing interval (for example, a cycle of 0.2 seconds, that is, 5 fps (frame / second)). Then, the image data is converted into a digital signal, compression-encoded, and image data compliant with a predetermined standard (for example, JPEG standard) is generated. The generated image data is output to the LAN and transmitted to the notification device 4. The image data transmitted at this time includes a camera number. Note that the surveillance camera 3 may compress and encode the audio signal input from the microphone to generate audio data, multiplex the image data and audio data, and output the multiplexed audio data to the LAN.

  The security sensor 7 is a monitoring unit that detects an intruder entering the inside of the area. The security sensor 7 stores a sensor number for identifying each security sensor 7 in advance, and outputs a detection signal including the sensor number to the notification device 4 when an intruder is detected.

  The reporting device 4 monitors an intruder entering the monitoring area 2 based on the detection signal from the security sensor 7 and the security mode set in the monitoring area 2. The security mode includes a security set mode as a monitoring mode and a security release mode as a non-monitoring mode. The security set mode is a mode that is set in an unattended state in which no user is present in the monitoring area 2, and when the security set mode is set, the reporting device 4 is intruded when receiving a detection signal from the security sensor 7. The intrusion detection signal is transmitted to the monitoring center 5. The security release mode is a mode that is set in a manned state where a user exists in the monitoring area 2, and the notification device 4 receives a detection signal from the security sensor 7 when the security release mode is set. Is not determined as an intrusion, and the intrusion detection signal is not transmitted to the monitoring center 5.

  Further, the notification device 4 receives the image data input from the monitoring camera 3, detects the posture of the person in the monitoring area 2 from the image data, and determines a predetermined posture (for example, both hands of the store clerk). If it is detected, a notification necessity determination process for determining necessity of notification according to a predetermined burglary occurrence factor is executed. If it is determined that the notification is necessary as a result of the notification necessity determination process, an emergency notification signal is notified to the monitoring center 5 via the communication network 6 and image data received from the monitoring camera 3 is transmitted to the monitoring center 5. . The image data transmission process is continuously performed until a stop input is received from a user of the monitoring center 5 or the monitoring area 2.

In particular, in the present embodiment, the reporting device 4 stores information on the number of people and the time zone in the monitoring area 2 as burglary occurrence status factors.
The reporting device 4 executes the emergency reporting process when detecting the predetermined posture of the person in the monitoring area 2 assuming that the risk of burglary occurrence is high when the number of persons in the monitoring area 2 becomes a predetermined number or less. In addition, a time zone with a high risk of burglary is stored in advance as a time zone required for notification, and emergency notification processing is executed when a predetermined posture of a person in the monitoring area 2 is detected when the current time is the time zone required for notification. .
As a result, the emergency call operation is surely performed in a situation where the monitoring area 2 is predicted to be quiet and the risk of burglary intrusion is high. To prevent it from happening.

  The monitoring center 5 is a facility provided with a center device 51 operated by a security company or the like. The center device 51 is composed of one or a plurality of computers, and realizes the function of the monitoring center 5 related to the present invention. In the monitoring center 5, various devices are controlled by the center device 51, and a suspicious person detection signal received as an emergency call from the reporting device 4 is recorded, and image data transmitted from the reporting device 4 is displayed on the display 52. The monitor monitors a plurality of monitoring areas 2 to be monitored.

<Notification device>
Next, the configuration of the notification device 4 will be described with reference to FIG. FIG. 2 is a block diagram showing the configuration of the notification device 4.
The notification device 4 is installed in the monitoring area 2 (in the present embodiment, the cashier counter area 2b) so as to be able to communicate with the monitoring camera 3, the security sensor 7, and the monitoring center 5.

  The reporting device 4 includes a monitoring information acquisition unit 41 as a communication I / F (interface) connected to the LAN, a communication unit 42 connected to the communication network 6, and an operation unit 43 on which a user performs an input operation. The storage unit 44 includes an HDD, a memory, and the like, and the control unit 45 includes an MPU, a microcomputer, and the like and controls each unit.

The monitoring information acquisition unit 41 is connected to the monitoring camera 3 and the security sensor 7 and receives the camera number and image data output from the monitoring camera 3 as the monitoring information of the monitoring area 2 and the detection signal output from the security sensor 7. The data is output to the control unit 45.
The communication unit 42 is connected to the center device 51 via the communication line network 6 and communicates with the monitoring center 5. When the control unit 45 determines that the notification is necessary, the communication unit 42 transmits an emergency notification signal including its own address information and image data captured by the monitoring camera 3 to the monitoring center 5. In addition, the communication unit 42 detects intrusion that includes its own address information when it is determined by the control unit 45 that an intruder exists in the area set in the guard set mode (the store area 2a and the cashier counter area 2b). A signal is transmitted to the monitoring center 5.
The operation unit 43 is a switch capable of inputting setting information such as a security mode setting operation.

  The storage unit 44 is configured by a ROM, a RAM, or an HDD, stores address information for identifying itself, various programs, and the like, and further stores various information for operating the reporting device 4. Specifically, the storage unit 44 is a burglar for performing reference data as background information for extracting a moving object, mode information indicating the current security mode, posture data information, and emergency call necessity determination processing. Occurrence status factor information is stored. Further, the storage unit 44 stores image data for a past predetermined time output from the monitoring camera 3.

  Here, the reference data stored in the storage unit 44 is comparison reference information used for extracting a moving object in the monitoring area 2 in comparison with the current image data in the visitor detection process described later. This is image data acquired by capturing an image of the monitoring area 2 in the unattended state in advance.

  Moreover, the mode information has memorize | stored the security mode (security set mode or security cancellation | release mode) currently set to the monitoring area 2 (the store area 2a and the cashier counter area 2b). The security mode is set by the control unit 45 based on an operation input to the operation unit 43 by the user.

Further, the posture data is predetermined posture data of a store clerk taken when an emergency such as a burglary occurs. Specifically, it is information of feature points and contour feature amounts corresponding to a predetermined posture by a specific person.
Robbery occurrence factor information includes the number of visitors information (for example, 3 people) that stores the number of people in the monitoring area 2 that needs to perform emergency call processing, and the time required for notification that stores the time zone when the risk of burglary occurrence is high. (For example, 2 am to 5 am).

  The control unit 45 includes a microcomputer including a CPU, a ROM, a RAM, and the like and peripheral circuits thereof, and controls each unit described above. For this purpose, the control unit 45 includes an electronic calendar unit 450 as a clock means for acquiring the current date and time as a functional module realized by the microcomputer and a computer program executed on the microcomputer, and a security mode of the monitoring area 2. By a mode setting unit 451 for setting / changing an intruder, an intruder detection unit 452 for detecting an intruder into the monitoring area 2, a visitor number detection unit 453 for detecting the number of visitors to the monitoring area 2, and a store clerk A posture detection unit 454 that detects a predetermined posture, a notification necessity determination unit 455 that determines whether notification is necessary, and a communication control unit 456 that controls communication processing by the communication unit 42 are provided.

  The mode setting unit 451 checks the information input from the operation unit 43 when the user sets the security mode, and if the verification is OK, sets the security mode of the monitoring area 2 based on the input of the operation unit 43 as a security set. Set to mode or security release mode. The security mode set by the mode setting unit 451 is stored in the mode information of the storage unit 44.

  As described above, the security set mode is set when the monitoring area becomes unmanned, such as a holiday, and an intrusion detection signal is sent to the remote monitoring center 5 via the communication unit 42 when the security sensor 7 detects a change in the event. This is a mode for reporting anomalies. Further, the security release mode is a mode that is set when the monitoring area is manned and does not perform abnormality notification by detection of the security sensor 7.

  When an intruder detection unit 452 receives a detection signal from the security sensor 7 via the monitoring information acquisition unit 41, the intruder detection unit 452 refers to the mode information stored in the storage unit 44 and the current security mode is in the security set mode. When the security sensor 7 outputs a detection signal, it is determined that there is an intruder in the monitoring area 2. On the other hand, if the security sensor 7 outputs a detection signal when the current security mode is the security release mode, the presence of an intruder is not determined. Information that the intruder detection unit 452 detects the intruder and information of the security sensor 7 that has output the detection signal are stored in the storage unit 44 and reported to the monitoring center 5 as an intrusion detection signal.

  The visitor number detection unit 453 performs image processing on the image data acquired by the monitoring information acquisition unit 41 (image data input from the monitoring camera 3) to detect the number of visitors to the monitoring area 2. In the number-of-entry detection unit 453, position information of an area (entrance / exit area) on the image including the entrance / exit 21 to the outside in the captured image data is set in advance corresponding to each monitoring camera 3. The visitor number detection unit 453 detects a fluctuating region newly appearing on the image from the entrance / exit region, detects the presence of the visitor, and obtains the number of visitors.

  Specifically, the number-of-entry detection unit 453 compares the reference data (image data when nobody is present) stored in the storage unit 44 with the current image data input from the monitoring information acquisition unit 41 to determine the luminance. A variation pixel whose value variation is equal to or greater than a predetermined value is extracted, a group of substantially continuous variation pixels is grouped as one variation region, and each variation region is labeled with a unique label. Then, the label detected in the previous frame process is associated with the label of the current frame by the tracking process. The association is performed according to the distance and size between the labels of both frames. The attendance detection unit 453 captures the label of the current frame that cannot be matched by the tracking process, that is, when an object that newly appears on the image data is located in the entrance / exit area, the image data of the object is captured. It is determined that it is a new visitor in the designated area. The visitor number detection unit 453 performs the above-described processing on the image data captured by each monitoring camera 3 to detect visitors to the monitoring area 2.

  The detection of the number of visitors is not limited to this, and any method may be used as long as the number of visitors to the monitoring area 2 can be detected. For example, a traffic detection sensor capable of detecting the direction in which a person has passed is installed at the entrance 21 to the outside in the monitoring area 2, and the notification device 4 sends a detection signal from the traffic detection sensor via the monitoring information acquisition unit 41. The number of visitors who received and detected the passing direction of the person who passed through the entrance / exit by the number-of-entry detection unit 453, and determined that there were visitors to the store area 2a and the office area 2b. You may ask for a number. As such a traffic detection sensor, various methods such as a method of providing a plurality of infrared sensors along the traffic direction and detecting the traffic direction according to the detection order are known.

In this embodiment, the posture detection method by the posture detection process executed by the posture detection unit 454 is detected from the image of the store clerk in the register counter area 2b photographed by the monitoring camera 3b.
There are various methods for posture detection processing. In this embodiment, the outline of an area in which a person is captured is extracted from an image, a plurality of feature points are set on the outline, and each of the plurality of feature points is set. For each of the other feature points different from the feature point, a distance from the feature point and a line segment connecting the feature point to the other feature point are determined based on the outline of the other feature point. The angle formed with the reference line is calculated as a contour feature value, and the posture of the person is detected using a plurality of contour feature values.
That is, the data of a plurality of contour feature values detected by the posture detection unit 454 is compared with the data of contour feature values of a predetermined posture stored in the storage unit 44.

When the posture detection unit 454 detects a predetermined posture by the store clerk in the cashier counter area 2b by the posture detection unit 454, the notification necessity determination unit 455 stores the number of visitors detected by the visitor number detection unit 453 as the storage unit 44. It is determined that an emergency call is necessary when the number of visitors is less than the number of visitors stored.
Further, when the current time corresponds to the time required for notification stored in the storage unit 44, it is determined that an emergency notification is necessary.

The communication control unit 456 transmits an emergency notification signal to the monitoring center 5 when it is determined by the notification necessity determination unit 455 that an emergency notification is necessary. The emergency notification signal includes address information of the notification device 4. Further, the communication control unit 456 starts transmitting image data input from the monitoring camera 3 to the monitoring center 5 when it is determined that an emergency call is required. The camera number and the address information of the reporting device 4 are added as header information to the transmitted image data, and the current image data is continuously transmitted each time it is input from the monitoring camera 3. The communication control unit 456 stops the image data transmission processing to the monitoring center 5 when receiving either the image transmission stop signal by the stop input of the operation unit 43 or the image transmission stop signal transmitted from the monitoring center 5. To do.
Further, the communication control unit 456 transmits an intrusion detection signal to the monitoring center 5 when the intruder detection unit 452 determines that an intruder exists in the area set in the guard set mode in the monitoring area 2. .

<Description of operation>
About the notification system 1 comprised as mentioned above, the operation | movement is demonstrated with reference to drawings. Here, the operation related to the emergency notification process by the notification device 4 will be mainly described. FIG. 3 is a flowchart showing the operation of the monitoring program repeatedly executed by the notification device 4.

  The notification device 4 accepts input of image data captured by the monitoring camera 3 from the monitoring information acquisition unit 41 at a predetermined cycle (for example, a cycle of 0.2 seconds, that is, 5 fps (frames / second)), and stores it in the storage unit 44. .

When the monitoring program shown in FIG. 3 is executed, the posture detection unit 454 detects the posture of the clerk in the checkout counter area 2b and determines whether or not the posture is a predetermined posture. In the posture detection process executed by the posture detection unit 454, it is determined that the posture of the person in the checkout counter area 2b matches the posture data set in advance. In the present embodiment, the outline of a person's region shown in the image data acquired by the monitoring information acquisition unit 41 is extracted, and a plurality of feature points are set on the outline. For each of the set feature points, the distance from the feature point and the line segment connecting the feature point to another feature point are different from each other feature point different from the feature point. An angle formed with a reference line determined based on the contour at the feature point is calculated as the contour feature amount.
Then, it is determined that the person in the cashier counter area 2b takes the predetermined posture when there is a similarity equal to or higher than a predetermined value compared with the contour feature amount of the posture data stored in the storage unit 44 in advance. To do.

As a result of the posture detection process, when a person with a predetermined posture is determined in the cashier counter area 2b (step ST2-Yes), the notification necessity determination unit 455 determines the necessity of emergency notification. The report necessity determination unit 455 acquires the number of people in the store area 2a from the number of visitors detection unit 453. The visitor number detection unit 453 performs image processing on the image data acquired by the monitoring information acquisition unit 41 and detects the number of visitors in the monitoring area 2. The notification necessity determination unit 455 reads the number of visitors information that is the burglary occurrence factor information from the storage unit 44. Here, for example, when the number of visitors information in the storage unit 44 is 3, it is determined whether or not the number of people detected by the number of visitors detection unit 453 is 3 or less.
If the number of persons detected by the number-of-entry detection unit 453 is not three or less (four or more), it is determined that there is no need for an emergency call (step ST4-No), and the process is terminated. . If the number is three or less, it is determined that an emergency call is necessary (step ST4-Yes), and the process proceeds to a process for transmitting an emergency call signal.

  The communication control unit 456 transmits an emergency notification signal to the monitoring center 5 (step ST5), and starts transmitting image data input from the monitoring camera 3 to the monitoring center 5 (step ST6). The transmission of the image data is continuously performed until an image transmission stop signal is input from the operation unit 43 or the monitoring center 5. When an image transmission stop signal is input from the operation unit 43 or from the monitoring center 5 (step ST7—Yes), the transmission of image data to the monitoring center 5 is stopped and the process is terminated (step ST8).

  On the other hand, when it is determined in step ST4 that the notification is not required (step ST4-NO), the execution of the emergency notification process is prohibited by skipping the processing of step ST5 to step ST8. Therefore, when there are more than a predetermined number of people in the store area 2a, it is possible to suppress an erroneous report of an emergency report.

  Note that the determination in step ST4 described above may not be determined based on the number of people in the monitoring area 2, but may be determined whether or not the time when the posture is detected is a dangerous time zone. In this case, the notification necessity determination unit 455 reads the notification required time information that is the burglary occurrence factor information from the storage unit 44 and compares it with the current time acquired from the electronic calendar unit 450. If the current time is not in the emergency call time zone, it is determined that no emergency call is necessary (step ST4-No), and the process is terminated. If the current time is an emergency call time zone, it is determined that an emergency call is necessary (step ST4-Yes), and the process proceeds to a process of transmitting an emergency call signal.

In the present embodiment, as the determination process of the notification necessity determination unit 455, the necessity of emergency notification is determined based on the number of visitors or the time zone in the store area 2a when a predetermined posture is detected. However, the present invention is not limited to this. For example, the necessity of notification may be determined according to the number of visitors set according to the time zone. Specifically, for example, since there is a high risk of robbery from midnight to 2:00 am, it is determined that an emergency call is required when the number of people in the store area 2a is 3 or less. From 2am to 5am, it is a time zone where the risk of robbery is highest, so it is determined that an emergency call is required even if the number of people in the store area 2a is 5 or less. In the case of, it is determined that an emergency call is required when the number of people in the store area 2a is two or less.
In the present embodiment, the necessity of reporting is determined based on the number of people in the store area 2a. However, the present invention is not limited to this. For example, the necessity of reporting depends on the number of people in the monitoring area 2 or the cashier counter area 2b. You may make it determine NO.

Further, the visitor detection unit 453 always counts the number of people in the store area 2a and stores it in the storage unit 44. When a predetermined posture is detected, the store area is detected within a predetermined time immediately before that. If the number of people within 2a is increasing, it may be determined that reporting is necessary.
Thereby, for example, when a burglar hits a crime with a plurality of persons, it is possible to prevent the number of robbers from being counted.

  The embodiments of the present invention have been described above by way of example, but the scope of the present invention is not limited to these embodiments, and can be changed or modified according to the purpose within the scope of the claims. is there.

  For example, in the present embodiment, an example has been described in which the monitoring information acquisition unit 41 acquires image data as monitoring information of the monitoring area 2 and performs entrance detection using the image data. However, the present invention is not limited to this. That is, the monitoring information is not limited to image data, and may be information that can identify and recognize a moving object in the monitoring area 2. For example, instead of the monitoring camera 3 or in addition to the monitoring camera 3, reflected light reflected by an object on the optical path by performing spatial scanning at a predetermined cycle while irradiating the monitoring area 2 with laser light as monitoring means A laser scanning distance sensor that detects the position of the object by obtaining the distance data to the object existing in the area and the irradiation direction by receiving the light may be used.

  In this case, the position (distance data and irradiation direction) of an object in the monitoring area 2 is input to the monitoring information acquisition unit 41 from the laser scanning distance sensor as monitoring information. As the reference data, the position of the existing object measured during unmanned operation is stored, and the variable object is extracted and labeled from the difference between the reference data and the position of the object in the current monitoring area 2, and is tracked with the previous period. It is determined whether or not it is a new appearance object. In the process of detecting the number of visitors, when a new appearance object is detected in the entrance / exit area set within the scanning range of the laser scanning distance sensor, it is detected as an attendant and the number of visitors is obtained.

  Further, in this embodiment, whether or not an emergency call is necessary is determined by the report necessity determination unit based on whether or not the clerk occurrence state factor is met when a predetermined attitude of the store clerk is detected. However, this is not limited to a predetermined attitude of the store clerk but may be a predetermined attitude of the customer, or may be a predetermined attitude in which a blade or a firearm for threatening the burglar is projected to the customer or the store clerk.
