  The in-vehicle monitoring device 1b is installed in a vehicle (see B1 and B2 in FIG. 1). In the present embodiment, description will be made assuming that the vehicle is mounted on the vehicle B1 and the vehicle B2 as an example. Here, an example of a schematic configuration of the in-vehicle monitoring device 1b will be described with reference to FIG.

  The communication device 11b is the same as the communication device 11a. Therefore, the description overlapping with the description of the communication device 11a is omitted, and the difference from the communication device 11a is described. The communication device 11b also corresponds to the communication unit in the claims.

  For example, the communication between the communication device 11b and the monitoring center 2 may be configured to use a communication module used for telematics communication such as DCM or a mobile phone connected by Bluetooth (registered trademark) communication.

A monitoring image around the subject vehicle captured by the camera 12b is output to the monitoring control device 15b. The camera 12b also corresponds to the monitoring camera in the claims. For example, the camera 12a may be configured to use a color camera using a CCD (Charge Coupled Device).

  As an example, the camera 12b is installed above the front bumper, for example, of the host vehicle so that the optical axis faces the front of the vehicle body, and images a region extending in a predetermined angular range in front of the host vehicle. The camera 12b is installed on the side surface of the host vehicle so that the optical axis faces diagonally forward from the side of the vehicle body or from the side of the vehicle body, and spreads in a predetermined range from the side of the vehicle or from the side of the vehicle to the diagonally front. It is good also as composition which picturizes a field. In addition, it is good also as a structure which combines these. The monitoring DB 14b is an electrically rewritable large-capacity storage device such as an HDD. The monitoring DB 14b also corresponds to a storage unit in claims.

  The position detector 16 includes, for example, a geomagnetic sensor for detecting geomagnetism, a gyroscope for detecting an angular velocity around the vertical direction of the own vehicle, a wheel speed sensor for detecting the speed of the own vehicle from the rotational speed of each rolling wheel, and a satellite. Based on information obtained from each sensor such as a GPS receiver for a global positioning system (GPS) that detects the current position based on radio waves, the current position is detected sequentially. The current position may be expressed by coordinates (latitude, longitude, altitude). Further, it is assumed that the traveling direction (azimuth angle) of the own vehicle is detected from the geomagnetic sensor. Note that the azimuth angle may be expressed as a positive azimuth with the north as the reference azimuth.

  Since these sensors have errors of different properties, they are configured to be used while being complemented by a plurality of sensors. Depending on the accuracy of each sensor, the position detector 16 may be configured by a part of the above-described sensors, or may be configured by using a sensor other than those described above.

  Further, in the present embodiment, the configuration in which the GPS receiver for GPS is used as the receiver of the satellite positioning system is shown, but the present invention is not necessarily limited thereto. For example, it is good also as a structure which uses the receiver of satellite positioning systems other than GPS.

  The alarm device 17 is a device for outputting an alarm sound, and outputs an alarm sound in accordance with an instruction from the monitoring control device 15b. The alarm device 17 may be configured to use, for example, a vehicle horn (sound alarm), or may be configured separately from the horn.

The monitoring control device 15b also corresponds to the monitoring control unit in the claims.

  The monitoring control device 15b is related to monitoring of a suspicious person by executing various control programs stored in the ROM based on various information input from the communication device 11b, the camera 12b, the monitoring DB 14b, and the position detector 16. Various processing such as processing to be performed (that is, monitoring related processing) is executed.

  Returning to FIG. 1, the monitoring center 2 is composed of a server device. The monitoring center 2 may be composed of one server device or may be composed of a plurality of server devices.

  Here, an example of a schematic configuration of the monitoring center 2 will be described with reference to FIG. As shown in FIG. 4, the monitoring center 2 includes a center side communication unit 21, a suspicious person information database (DB) 22, and a center side control unit 23.

  The center side communication unit 21 receives information such as a suspicious person information response message and a suspicious person detection message transmitted from the fixed monitoring device 1 a and the in-vehicle monitoring device 1 b and outputs the information to the center side control unit 23. Further, the center side communication unit 21 transmits a suspicious person detection notification to be described later to a server device of an organization that performs security or public service related to security based on an instruction from the center side control unit 23. Further, the center side communication unit 21 also transmits a suspicious person detection notification to the user terminal 3 based on an instruction from the center side control unit 23.

  The organization that performs public duties or services related to security here refers to, for example, the police, security companies, communication companies that provide security services, and the like. In addition, what is necessary is just to set it as the structure which performs the communication with the center side communication part 21 and the server apparatus of the structure | organization which performs the public affairs or service regarding the vehicle-mounted monitoring apparatus 1b, the fixed monitoring apparatus 1a, the user terminal 3, and security.

  The center-side control unit 23 is configured as a normal computer, and includes a well-known CPU, a memory such as a ROM, a RAM, and an EEPROM, an I / O, and a bus line for connecting these configurations (all not shown). Etc.). The center-side control unit 23 executes various processes such as a suspicious person detection notification-related process described later based on various information input from the center-side communication unit 21 and the suspicious person information DB 22. For example, the center-side control unit 23 stores the suspicious person information response message and the suspicious person detection message received from the fixed monitoring apparatus 1a and the in-vehicle monitoring apparatus 1b in the suspicious person information DB 22.

  Returning to FIG. 1, the user terminal 3 is a terminal device used by the user. For example, as the user terminal 3, a mobile phone, a tablet computer, a notebook PC, a desktop PC, a PDA (Personal Digital Assistants), or the like can be used. In addition, it is possible for the user to quickly recognize that a suspicious person detection notification or a suspicious person movement route notification, which will be described in detail later, has been received, and to quickly know the contents of the suspicious person detection notification or the suspicious person movement route notification. From a viewpoint, it is more preferable to use a mobile terminal carried by a user such as a mobile phone.

  In the present embodiment, the following description will be given by taking as an example the case where a touch panel type mobile phone is used as the user terminal 3. For the sake of convenience, among the configurations relating to the functions of a general touch panel type mobile phone, those not necessary for the description of the present invention will be omitted.

  Here, an example of a schematic configuration of the user terminal 3 will be described with reference to FIG. As illustrated in FIG. 5, the user terminal 3 includes a terminal-side communication unit 31, a terminal-side storage unit 32, a display unit 33, an operation input unit 34, and a terminal-side control unit 35.

  The terminal side communication unit 31 receives information such as a suspicious person detection notification and a suspicious person movement route notification transmitted from the monitoring center 2 and outputs them to the terminal side control unit 35. The display unit 33 is configured using, for example, a liquid crystal display or an organic EL display capable of full color display.

  For example, a touch switch or a mechanical switch integrated with the display unit 33 is used as the operation input unit 34, and various operation instructions are given to the terminal-side control unit 35 by a switch operation.

  The terminal-side control unit 35 is configured as a normal computer, and includes a well-known CPU, a memory such as a ROM, a RAM, and an EEPROM, an I / O, and a bus line for connecting these configurations (all not shown). Etc.). The terminal-side control unit 35 performs processing related to display of the contents of the suspicious person detection notification and the suspicious person movement route notification based on various information input from the terminal-side communication unit 31, the terminal-side storage unit 32, and the operation input unit 34. Various processes such as these are executed.

  Subsequently, an example of a processing flow in the monitoring area monitoring system 100 will be described with reference to the sequence diagram of FIG. Here, a case where a suspicious person is detected by the fixed monitoring device 1a of the house A and a suspicious person information request message is transmitted from the fixed monitoring device 1a to the in-vehicle monitoring device 1b of the vehicle B1 or B2 will be described as an example. I do.

  First, the fixed monitoring device 1a performs monitoring related processing (t1). Here, an outline of the monitoring-related processing will be described using the flowchart of FIG. The flow in FIG. 7 is started when the fixed monitoring device 1a is activated, for example, when the power of the fixed monitoring device 1a is turned on.

  In step S1, the monitoring control device 15b performs imaging-related processing, and proceeds to step S2. In the imaging-related processing, every time a monitoring image sequentially captured by the camera 12a is acquired, the monitoring image is captured with the date and time of the monitoring image, the camera position of the camera 12a that captured the monitoring image, and when the monitoring image is captured. Is associated with information on the imaging direction of the camera 12a and stored in the monitoring DB 14a (see FIG. 10). Therefore, the processing in step S1 corresponds to the image storage means in the claims.

  The information stored in the monitoring DB 14a may be deleted from the old information when the capacity of the monitoring DB 14a is exceeded, or may be deleted after a certain period of time has elapsed since the storage. Good.

  The camera position of the camera 12a is represented by coordinates (latitude, longitude, altitude), for example. The imaging direction of the camera 12a is represented by the azimuth angle and elevation angle of the optical axis of the camera 12a. The azimuth angle may be based on the north, and the elevation angle may be based on the horizontal.

  When the camera position and the imaging direction of the camera 12a are fixed, for example, by storing a value measured in advance when the camera 12a is installed in a nonvolatile memory such as an EEPROM of the monitoring control device 15b, What is necessary is just to make it the structure which can be utilized. Further, when the camera position and imaging direction of the camera 12a can be changed, it is the same as that used in a technique for recording the imaging position and the azimuth angle and elevation angle at the time of imaging in a known digital camera or the like. A configuration may be employed in which the camera position and the imaging direction are sequentially determined using technology.

  In the imaging-related processing, when a plurality of cameras 12a are installed, the imaging date and time, the camera position, and the imaging direction are stored in association with the captured image for each camera 12a.

  In step S2, the monitoring control device 15b performs suspicious person detection related processing, and proceeds to step S3. Here, the outline of a suspicious person detection related process is demonstrated using the flowchart of FIG.

  First, in step S21, a suspicious person presence determination process is performed, and the process proceeds to step S22. In the suspicious person presence determination process, it is determined whether or not there is a suspicious person in the set monitoring area based on the monitoring image stored in the monitoring DB 14a in the imaging related process. This step S21 corresponds to the suspicious person judging means in the claims.

  The monitoring area referred to here is, for example, represented by a closed circuit connecting a plurality of coordinates (latitude, longitude, and altitude in this example). The monitoring area may be fixed or may be switchable to a plurality of patterns. For example, the monitoring area may be set in advance through an operation input unit (not shown) of the fixed monitoring device 1a.

  Here, an example of the monitoring area will be described with reference to FIG. A of FIG. 9 represents the above-mentioned house A, and a hatched area represents a monitoring area. As an example, the monitoring area may be set in a garden or parking lot around a building in the site of the house A, and a suspicious person who has entered the garden or parking lot in the site of the house A may be detected. In addition, the camera 12a is installed so as to capture an image of the inside of the monitoring area, and the threatening device 13a is installed so as to be able to threaten a suspicious person who has entered the monitoring area.

  Moreover, what is necessary is just to make the determination whether a suspicious person exists using the well-known image recognition technique. For example, an example of an image of a person in any posture (that is, an example of a correct image) and an example of an image of a structure that is clearly not a person (that is, an example of an inaccurate image) are stored in a non-volatile memory such as an EEPROM of the supervisory control device 15a Store it. An image similar to the non-correct image example stored in the nonvolatile memory is removed, while an image similar to the correct image example is detected as a suspicious candidate image.

  Further, an image example of the resident of the house A and the acquaintance (hereinafter, an excluded image example) is also stored in a non-volatile memory such as an EEPROM of the monitoring control device 15a, and images similar to this excluded image example are excluded. What is necessary is just to set it as the structure which determines with a suspicious person existing in a monitoring area, when a suspicious person candidate image is obtained. Further, a person included in the suspicious person candidate image is detected as a suspicious person.

  Various specific algorithms for pattern matching can be employed. For example, pattern matching may be performed using a pattern discriminator constructed by machine learning using boosting such as a neural network or AdBoost, a support vector machine, or the like.

  Moreover, although the structure which determines with a suspicious person existing is shown here when the monitoring image containing the person except the inhabitant of the house A and the acquaintance is obtained, the structure which determines that a suspicious person exists is not necessarily restricted to this. For example, it may be configured to determine that there is a suspicious person when a monitoring image including a person is obtained regardless of whether the person is a resident of the house A, his / her acquaintance, or another person.

  In step S22, when it is determined that there is a suspicious person in the suspicious person presence determination process (YES in step S22), the process proceeds to step S23. On the other hand, if it is determined in the suspicious person presence determination process that there is no suspicious person (NO in step S22), the process proceeds to step S29.

  In step S23, the suspicious person detection flag is turned on, and the process proceeds to step S24. In step S24, the threatening device 13a is driven to threaten the suspicious person, and the process proceeds to step S25. In step S25, a feature extraction process is performed and the process proceeds to step S26. In the feature extraction process, based on the image of the suspicious person detected in the suspicious person presence determination process, the feature of the suspicious person is extracted using a known image recognition technique.

  Further, the extracted suspicious person feature is added to the monitoring image in which the suspicious person is detected, linked and stored in the monitoring DB 14a (see FIG. 10). The suspicious person feature is not associated with the monitoring image in which the suspicious person is not detected (see “None” in FIG. 10).

  As an example, by performing pattern matching using image examples for each part of the human body and equipment such as shoes, each part and equipment of the human body of the suspicious person is specified, and the color ratio and shape of the image are also included. In addition, it may be configured to extract features such as clothing color, hair color, eye color, shoe color, clothing type, shoe type, and gender. Further, the height of the suspicious person may be extracted based on the size of the suspicious person in the monitoring image. In addition, it is good also as a structure which adds the image data of the part which extracted the characteristic as a suspicious person characteristic to a monitoring image, links | relates and preserve | saves it in monitoring DB14a.

  In step S26, a position estimation process is performed and the process proceeds to step S27. In the position estimation process, the coordinates of the position of the suspicious person detected in the suspicious person presence determination process (hereinafter referred to as suspicious person position) are estimated. Therefore, the process of step S26 corresponds to the suspicious person position estimating means in the claims. As an example, the position of the object in the monitoring image can be converted into actual coordinates (latitude / longitude / altitude in this example) if the suspicious person position is determined by the camera position and imaging direction of the camera 12a. For this reason, a configuration that uses this for estimation may be used.

  Further, the extracted suspicious person position is also added to the monitoring image in which the suspicious person is detected, linked and stored in the monitoring DB 14a (see FIG. 10). For the monitoring image in which no suspicious person is detected, the position of the suspicious person is not linked (see “None” in FIG. 10). In addition, it is good also as a structure which determines a suspicious person's position using this ranging sensor by providing the ranging sensor which detects the distance to an obstruction in the fixed monitoring apparatus 1a.

  In step S27, a request message generation process is performed, and the process proceeds to step S28. In the request message generation process, a suspicious person information request message is generated for a suspicious person determined to be present in the monitoring area in the suspicious person presence determination process. Therefore, the process in step S27 corresponds to the request generation unit in the claims.

  For example, as shown in FIG. 11, the suspicious person information request message includes “identification information (for example, device ID)” for specifying the transmission source device, “message ID” indicating the message type, and position estimation processing. Estimated “suspicious person position”, “detection date and time” indicating the date and time of detection of the suspicious person, “characteristic of the suspicious person (hereinafter referred to as suspicious person characteristic)” extracted by the feature extraction process, and the period for which information on the suspicious person is collected The “collection period” for designating the information, and the “collection area” information for designating the area from which the information of the suspicious person is collected. Note that “collection period” information corresponds to claim period designation information, and “collection area” information corresponds to claim area designation information.

  What is necessary is just to set it as the structure which acquires and uses "apparatus ID" previously recorded on non-volatile memories, such as ROM of the fixed monitoring apparatus 1a. The “message ID” may be determined by selecting an ID set in advance for each message type. As an example, as shown in FIG. 12, the suspicious person information request message is set to “0”, the suspicious person information response message described later is set to “1”, and the suspicious person detection message described later is set to “2”. In the case of a suspicious person information request message, “0” is selected and determined as “message ID”. The detection date and time may be the imaging date and time of the monitoring image including the suspicious person.

  The “collection period” includes, for example, a collection start date and time and a collection end date and time, and specifies at least a period that goes back to the past, such as ten or so minutes before and after the imaging date and time of the monitoring image including the suspicious person. As an example, a collection start date / time “December 1, 2011 00: 15: 30.220 seconds”, a collection end date “December 1, 2011 00: 35: 30.220 seconds”, and the like are designated. And it is sufficient. The “collection area” is designated by a plurality of coordinates such as a coordinate group representing a range of about several tens of meters from the site of the house A.

  In step S28, a request message transmission process is performed, and the process proceeds to step S3. In the request message transmission process, the suspicious person information request message generated in the request message generation process is transmitted from the communication device 11a within the communication range of the communication device 11a (see the broken circle in FIG. 14). Therefore, the processing in step S27 corresponds to the request transmission means in the claims.

  In step S29 when it is determined that there is no suspicious person in step S22, if the suspicious person detection flag is on (YES in step S29), the process proceeds to step S30. On the other hand, if the suspicious person detection flag is off (NO in step S29), the process proceeds to step S3. In step S30, the threatening device 13a is stopped and the process proceeds to step S30. In step S31, the suspicious person detection flag is turned off, and the process proceeds to step S3.

  The suspicious person presence / absence determination processing may be performed every time a new monitoring image is obtained in the imaging-related processing, or whenever the monitoring image newly stored in the imaging-related processing reaches a certain period or a certain amount of capacity. It is good also as a structure to perform.

  Returning to FIG. 7, in step S <b> 3, the monitoring control device 15 a determines whether or not a suspicious person information request message has been received from a fixed monitoring device 1 a other than its own device or the in-vehicle monitoring device 1 b. For example, when a suspicious person information request message is input from the communication device 11a within a certain period, it is determined that the suspicious person information request message is received, and the suspicious person information request message is input from the communication device 11a within a certain period. If not, it may be determined that the suspicious person information request message has not been received.

  And when it determines with having received the suspicious person information request message (it is YES at step S3), it moves to step S4. On the other hand, if it is determined that the suspicious person information request message has not been received (NO in step S3), the flow returns to step S1 to repeat the flow.

  In step S4, the monitoring control device 15a performs a request message response process and returns to step 1. Here, an outline of the request message response process will be described with reference to the flowchart of FIG. In step S3 and step S4, when returning to step S1 and repeating the flow and performing the suspicious person presence determination process again, the monitoring date and time is newer than the monitoring image already used in the suspicious person presence determination process in the past. A suspicious person presence determination process is performed on the image.

  First, in step S41, a first record extraction process is performed, and the process proceeds to step S42. In the first record extraction process, based on the “collection period” included in the received suspicious person information request message, the monitoring image captured in the “collection period” is stored in the monitoring DB 14a of the own apparatus. Select from and extract.

  In step S42, the second record extraction process is performed, and the process proceeds to step S43. In the second record extraction process, based on the “collection area” included in the received suspicious person information request message, the monitoring image captured at the camera position in the “collection area” is extracted by the first record extraction process. The selected surveillance images are selected and further extracted.

  In step S43, a feature determination process is performed, and the process proceeds to step S44. The process of step S43 corresponds to a feature determination unit in the claims. In the feature determination process, based on the “suspicious person feature” included in the received suspicious person information request message, a monitoring image including a suspicious person having a feature similar to the “suspicious person feature” is extracted as a second record. It is determined whether or not it is included in the monitoring image extracted by the processing. That is, it is determined whether or not a suspicious person having a feature similar to the “suspicious person feature” is included in the monitoring image stored in the monitoring DB 14a.

  As an example, the suspicious person characteristic associated with the monitoring image extracted in the second record extraction process is compared with the “suspicious person characteristic” included in the received suspicious person information request message. When the matching feature is equal to or greater than a predetermined ratio, a monitoring image including a suspicious person having a feature similar to the “suspicious person feature” included in the suspicious person information request message is obtained in the second record extraction process. It is determined that it is included in the extracted monitoring image. On the other hand, if the matching features are less than the predetermined ratio, it is determined that they are not included. The predetermined ratio here is an arbitrarily settable value greater than zero.

  In addition, when the image data of the characteristic part of the suspicious person is received as the “suspicious person characteristic” included in the suspicious person information request message, known pattern matching is performed based on the image data. It is good also as a structure. Then, when a matching monitoring image is obtained, the monitoring image including the suspicious person having a feature similar to the “suspicious person feature” included in the suspicious person information request message is extracted by the second record extraction process. It is good also as a structure determined to be contained in the image.

  If it is determined in the feature determination process that a suspicious person having a similar feature is included (YES in step S44), the process proceeds to step S45. On the other hand, if it is determined that it is not included (NO in step S44), the process returns to step 1 without generating / transmitting a suspicious person information response message described later.

  In step S45, the third record extraction process is performed, and the process proceeds to step S46. In the third record extraction process, the monitoring image determined in the feature determination process as a monitoring image including a suspicious person having a feature similar to the “suspicious person characteristic” included in the suspicious person information request message is stored in the second record extraction process. Extracted from the monitoring images extracted in.

  In step S46, a response message generation process is performed, and the process proceeds to step S47. In the response message generation process, a suspicious person information response message for the suspicious person requested by the suspicious person information request message is generated based on the monitoring image extracted in the third record extraction process. Therefore, the processing in step S46 corresponds to the response generation means in the claims.

  For example, as shown in FIG. 13, the suspicious person information response message includes “identification information (for example, device ID)” for identifying the transmission source device, “message ID” indicating the type of message, and the position of the suspicious person. `` Suspicious person position '' indicating `` camera position '' indicating the camera position when the surveillance image is captured, `` imaging direction '' indicating the imaging direction when the surveillance image is captured, `` imaging date and time '' indicating the imaging date and time of the surveillance image, It consists of information of “suspicious person image” including the suspicious person.

  The “device ID” and “message ID” may be determined in the same manner as in the generation of the suspicious person information request message. The “suspicious person position” and “imaging date and time” may be configured to use the suspicious person position and imaging date and time associated with the extracted monitoring image. Regarding the “suspicious person image”, the extracted monitoring image may be the “suspicious person image”, or the image of the area including the suspicious person in the extracted monitoring image may be the “suspicious person image”.

  Note that it is more preferable that the image of the area including the suspicious person is the “suspicious person image” because the data amount of the suspicious person information response message can be suppressed. The suspicious person information response message may not include “camera position” and “imaging direction”.

  In step S47, a response message transmission process is performed, and the flow returns to step S1 to repeat the flow. In the response message transmission process, the suspicious person information response message generated in the response message generation process is transmitted from the communication device 11a.

  Here, the communication protocol for wireless communication between the fixed monitoring device 1a and the in-vehicle monitoring device 1b may be configured to use an ad hoc communication protocol such as a mesh net or MANET (mobile ad hoc network). In addition, a configuration using a geocast protocol for transmitting information to nodes existing in a specified specific area may be used, or a configuration using a protocol for distributing information to a specific area using a mobile phone or multicast. Also good.

  Returning to FIG. 6, when a suspicious person is detected by the fixed monitoring device 1a of the house A, a suspicious person information request message is transmitted (t2). At this time, the in-vehicle monitoring device 1b of the vehicles B1 and B2 performs the monitoring related process similarly to the fixed monitoring device 1a (t3, t4). When the suspicious person information request message is received, the monitoring control device 15b transmits (replies) the suspicious person information response message to the fixed monitoring device 1a of the house A (t5, t6). Therefore, the monitoring control device 15b also corresponds to the feature determination unit, the response generation unit, and the response transmission unit.

  The in-vehicle monitoring device 1b receives the suspicious person information response message transmitted by the in-vehicle monitoring device 1b of the vehicle B2 and transfers it to the fixed monitoring device 1a of the house A so that the in-vehicle monitoring device 1b transmits the suspicious person information response message. It is good also as a structure which the other vehicle-mounted monitoring apparatus 1b receives and transfers the transmitted suspicious person information response message. In this case, a known multi-hop communication protocol may be used.

  Here, the monitoring related processing in the in-vehicle monitoring device 1b will be described. The monitoring-related processing in the in-vehicle monitoring device 1b is the same as the monitoring-related processing in the fixed monitoring device 1a except that some of the processing is different. Therefore, different points will be described below.

  First, in the imaging-related process of the monitoring-related processes, the camera position and the imaging direction of the camera 12b change depending on the travel of the vehicles B1 and B2, and therefore the mounting position and the mounting position of the camera 12b on the vehicles B1 and B2 In addition to the direction of the optical axis, the monitoring control device 15b sequentially determines the current position and azimuth detected by the position detector 16 of the vehicles B1 and B2.

  The camera position of the camera 12b may be determined from the current position of the host vehicle detected by the position detector 16 and the mounting position of the camera 12b on the host vehicle. The information on the mounting position of the camera 12b is, for example, the relative position of the camera 12b with respect to the mounting position of the GPS receiver of the own vehicle. In this case, the position determined by the relative position from the current position of the vehicle detected by the position detector 16 may be determined as the camera position of the camera 12b.

  For example, it is assumed that the relative position of the camera 12b with respect to the mounting position of the GPS receiver of the host vehicle is stored in advance in a non-volatile memory of a vehicle system (for example, ECU) (not shown) of the host vehicle. And the monitoring control apparatus 15b shall be able to set automatically the information of the attachment position of the camera 12b by acquiring this relative position via vehicle-mounted LAN19 grade | etc.,. In addition, when the sensor which detects the relative position of the camera 12b with respect to the mounting position of the GPS receiver of the own vehicle can be utilized, it is good also as a structure which preserve | saves the value detected by this sensor previously in the non-volatile memory of a vehicle system.

  According to this, when installing the monitoring control device 15b for the first time in the own vehicle, or when replacing the monitoring control device 15b after buying the own vehicle, information on the mounting position of the camera 12b can be set from the vehicle system. As a result, it is not necessary for the user to set information on the attachment position of the monitoring control device 15b, and convenience is increased.

  The imaging direction of the camera 12b may be determined from the azimuth angle of the own vehicle detected by the position detector 16 and the direction of the optical axis at the position where the camera 12b is attached to the own vehicle. For example, the orientation of the optical axis at the position where the camera 12b is attached to the host vehicle is, for example, an azimuth angle based on the traveling direction of the host vehicle when traveling straight and an elevation angle based on the horizontal. In this case, if the angle obtained by adding the azimuth angle based on the traveling direction when the vehicle is traveling straight to the azimuth angle detected by the position detector 16 is determined as the azimuth angle in the imaging direction. Good. Moreover, what is necessary is just to determine the elevation angle on the basis of the horizontal of the optical axis in the attachment position to the own vehicle of the camera 12b as an elevation angle in an imaging direction.

  As for the relative position of the camera 12b with respect to the mounting position of the GPS receiver of the own vehicle and the direction of the optical axis of the camera 12b, for example, values measured in advance when the camera 12b is installed are stored in the nonvolatile memory of the vehicle system in advance. It may be configured to keep.

  In the suspicious person presence determination process in the monitoring related process, the monitoring area is set in a garden or a parking lot around a building in the site of a house or the like to be watched (for example, a house A) and is set as a watch target. What is necessary is just to make it detect the suspicious person who invaded the garden and parking lot in site | parts, such as a house. It is assumed that the monitoring image is captured by the camera 12b sequentially even outside the monitoring area.

  Intimidation performed when it is determined that there is a suspicious person in the suspicious person presence determination process is performed by outputting an alarm sound from the alarm device 17 or irradiating light from the lighting device 18.

  The transmission of the suspicious person information request message from the in-vehicle monitoring device 1b may be performed toward the fixed monitoring device 1a, or may be configured toward the in-vehicle monitoring device 1b of a vehicle other than the own vehicle. However, it is also possible to adopt a configuration for performing both.

  In the request message response process of the monitoring related processes, the following process may be performed between the third record extraction process and the response message generation process.

  First, following the third record extraction process, a vehicle number estimation process is performed. In the vehicle number estimation process, the number of transmission sources of packets received per unit time in vehicle-to-vehicle communication is estimated as the number of surrounding vehicles performing vehicle-to-vehicle communication. Therefore, the monitoring control device 15b corresponds to the vehicle number estimation means in the claims. The number of packet transmission sources may be configured such that, for example, the same transmission source packet is not counted repeatedly based on the transmission source device ID included in the packet.

  Subsequent to the vehicle number estimation process, an allocation amount estimation process is performed. In the allocation amount estimation process, based on the number of surrounding vehicles estimated in the vehicle number estimation process, the vehicle and the monitoring device 1 (in this example, the fixed monitoring device 1a of the house A) that is the transmission source of the suspicious person information request message When it is assumed that the surrounding vehicle transmits a suspicious person information response message from the communication device 11b, the allocated amount of communication capacity (communication path capacity) per vehicle is estimated. Therefore, the monitoring control device 15b corresponds to the allocated amount estimation means in the claims.

As an example, the value calculated by Equation 1 below may be configured to estimate the allocated amount of communication capacity. Note that the communicable period in Equation 1 is an estimated time during which the in-vehicle monitoring device 1b can communicate with the fixed monitoring device 1a that is the transmission source of the suspicious person information request message. Further, the capacity per record in Expression 1 is, for example, the capacity of one monitoring image, and may be configured to use a virtually determined fixed value.

  In the response message generation process subsequent to the allocation amount estimation process, the monitoring image is further extracted by randomly extracting the monitoring image extracted in the third record extraction process so as not to exceed the allocation amount estimated in the allocation amount estimation process. Narrow down. If the monitoring image extracted by the third record extraction process is less than or equal to the allocated amount, it is not necessary to perform the narrowing down. And a suspicious person information response message is produced | generated from the monitoring image narrowed down so that it may not exceed the allocation amount estimated by the allocation amount estimation process.

  The monitoring image is not limited to being extracted at random. For example, the monitoring image may be extracted according to a certain rule, for example, when the imaging date and time are separated by a certain period or more. In addition, the monitoring image including the suspicious person's face image is determined by the monitoring control device 15b from among the monitoring images extracted by the third record extraction process, and the monitoring image including the suspicious person's face image is preferentially extracted. It is good also as composition to do. Details are as follows.

  First, with respect to the monitoring image extracted by the third record extraction process, an attempt is made to extract the image of the suspicious person's face by a known image recognition technique (for example, pattern matching), and the monitoring image from which the face image has been extracted The monitoring control device 15b makes a determination. Therefore, the monitoring control device 15b corresponds to a determination unit in the claims.

  Subsequently, from the monitoring image extracted in the third record extraction process, the monitoring image from which the suspicious person's face image has been extracted is preferentially extracted, and the remaining amount so as not to exceed the allocation amount estimated in the allocation amount estimation processing. For example, the monitoring images are extracted at random to narrow down the monitoring images. And a suspicious person information response message is produced | generated from the monitoring image narrowed down so that it may not exceed the allocation amount estimated by the allocation amount estimation process.

  In addition, about the monitoring image preserve | saved in monitoring DB14a, the image of the suspicious person's face part is previously extracted by the well-known image recognition technique (for example, pattern matching) etc., and the tag which shows the monitoring image containing a face image is provided. If it is given, the monitoring control device 15b may discriminate the monitoring image from which the face image has been extracted based on this tag.

  According to the above configuration, in wireless communication with a limited communication path capacity, it is possible to prevent congestion by limiting the communication amount of the suspicious person information response message according to the number of vehicles existing in the vicinity. In addition, when limiting the amount of suspicious person information response message traffic, the monitoring image including the suspicious person's face image is preferentially extracted and the monitoring image to be transmitted is narrowed down to efficiently provide evidence with a limited amount of communication. It becomes possible to transmit information with high capability. Therefore, it is possible to efficiently collect information with high evidence capacity with a limited communication amount on the receiving side.

  The in-vehicle monitoring device 1b that has received the suspicious person information request message from the fixed monitoring device 1a may notify the vehicle occupant of the information on the suspicious person based on the suspicious person information request message. As an example, the supervisory control device 15b displays text or an image indicating the suspicious person feature included in the suspicious person information request message on a display (not shown), or the supervisory control device 15b provides voice guidance explaining the suspicious person feature from the speaker. It may be configured to output. In addition, the monitoring control device 15b may display the suspicious person position included in the suspicious person information request message on a map of a navigation device (not shown).

  According to this, since it becomes possible to promptly notify the occupant (for example, driver) of the surrounding vehicle of the site of the building where the suspicious person is detected, the driver encounters the suspicious person without noticing. Risk can be reduced. For example, if a suspicious person can be recognized during driving, it is possible to take an action to avoid an intentional traffic accident by the suspicious person by defensive driving for avoiding the accident.

  Returning to FIG. 6, the fixed monitoring device 1a of the house A that has received the suspicious person information response message returned from the in-vehicle monitoring device 1b of the vehicles B1 and B2 from the in-vehicle monitoring device 1b of the vehicles B1 and B2 The received suspicious person information response message is transmitted (transferred) from the communication device 11a to the monitoring center 2 in accordance with an instruction from the monitoring control device 15a.

  At this time, the fixed monitoring device 1a of the house A generates a suspicious person detection message for the suspicious person detected by the own device by the monitoring control device 15a, and the suspicious person detection message is also communicated according to the instruction of the monitoring control device 15a. Transmission is performed from the device 11a to the monitoring center 2 (t7). Therefore, the monitoring control device 15a corresponds to the monitoring device-side transmission means in the claims.

  The suspicious person detection message may be generated based on information stored in the monitoring DB 14a. For example, as shown in FIG. 16, the suspicious person detection message is estimated by “identification information (for example, device ID)” for specifying the transmission source device, “message ID” indicating the message type, and position estimation processing. "Suspicious person position", "Detection date and time" indicating the detection date and time of the suspicious person, "Camera position" indicating the camera position when the surveillance image including the suspicious person is captured, and the imaging direction when capturing the surveillance image It consists of information of “imaging direction” and “suspicious person image” including the suspicious person. The “device ID”, “message ID”, “suspicious person position”, “detection date / time”, and “suspicious person image” are the same as described above.

  Returning to FIG. 6, the monitoring center 2 receives the suspicious person information response message and the suspicious person detection message transmitted from the fixed monitoring device 1 a of the house A by the center side communication unit 21. Therefore, the center side communication part 21 is equivalent to the center side receiving means of a claim. And the monitoring center 2 performs a suspicious person detection notification generation process which produces | generates a suspicious person detection notification based on the suspicious person information response message and suspicious person detection message which were received from the fixed monitoring apparatus 1a of the house A (t8). .

  For example, as shown in FIG. 17, the suspicious person detection notification includes a “detection date and time” indicating the detection date and time of the suspicious person, a “suspicious person position” indicating the position of the suspicious person, and a camera at the time of capturing a monitoring image including the suspicious person. It is assumed that the information includes a “camera position” indicating a position, an “imaging direction” indicating an imaging direction when the monitoring image is captured, and “suspicious person image” including a suspicious person.

  As an example, when generating a suspicious person detection notification from a suspicious person information response message, the “imaging date”, “suspicious person position”, “camera position”, “imaging direction”, “suspicious direction” included in the suspicious person information response message The “person image” is used as the “detection date”, “suspicious person position”, “camera position”, “imaging direction”, and “suspicious person image” of the suspicious person detection notification. Further, when generating a suspicious person detection notification from a suspicious person detection message, “detection date”, “suspicious person position”, “camera position”, “imaging direction”, “suspicious person image” included in the suspicious person detection message Are used as “detection date / time”, “suspicious person position”, “camera position”, “imaging direction”, and “suspicious person image” of the suspicious person detection notification.

  Then, the suspicious person detection notification generated by the suspicious person detection notification generating process is transmitted (reported) from the center side control unit 23 to the server device of the organization that performs public duties or services related to security (t9). Therefore, the center side control part 23 is equivalent to the report means of a claim. According to this, it becomes possible to promptly notify the existence of a suspicious person to an organization that conducts public affairs or services related to security, such as a police or a security company, and it is possible to prompt the suspicious person to be cleared. At the same time, the user is notified of the existence of the risk, the risk of accidentally encountering a suspicious person is suppressed, and the spread of crime damage is suppressed.

  The monitoring center 2 transmits (notifies) the generated suspicious person detection notification to the user terminal 3 of the resident of the house A (t10). Therefore, the center side control part 23 is equivalent to the user notification means of a claim. Note that the notification of the suspicious person detection notification to the user may be configured such that the content of the suspicious person detection notification is made by an electronic message such as an e-mail, a messenger, or Twitter, or may be made by telephone.

  According to this, it becomes possible to promptly notify the user of the existence of the suspicious person, it is possible to suppress the risk of accidentally encountering the suspicious person, and to suppress the spread of crime damage.

  The user terminal 3 of the resident of the house A that has received the suspicious person detection notification transmitted from the monitoring center 2 by the terminal side communication unit 31 performs the suspicious person detection notification process based on the received suspicious person detection notification (t11). ). Therefore, the terminal side communication part 31 is equivalent to the detection notification receiving means of a claim. Here, an outline of the suspicious person detection notification process will be described with reference to the flowchart of FIG.

  First, in step S51, the terminal-side control unit 35 performs incoming call notification processing, and proceeds to step S52. In the incoming call notification process, the user is informed that a suspicious person detection notification has been received by outputting a ringtone from a speaker (not shown) or vibrating the user terminal 3 using a vibration function.

  In step S52, the terminal-side control unit 35 determines whether there is a display action from the user. For example, in the case of a configuration in which a list of a plurality of suspicious person detection notifications is displayed on the display unit 33, when a user operation for selecting a specific suspicious person detection notification from this list is received by the operation input unit 34, It may be configured to determine that there is a display action from.

  In addition, when a point on the map indicating the camera position or the suspicious person position included in each suspicious person detection notification is displayed on the display unit 33, a specific point is selected from the points on the map. When a user operation is accepted by the operation input unit 34, it may be configured to determine that there is a display action from the user.

  If it is determined that there is a display action (YES in step S52), the process proceeds to step S53. On the other hand, if it is determined that there is no display action (NO in step S53), the flow of step S52 is repeated.

  In step S53, the terminal side control part 35 performs a suspicious person detection information display process, and complete | finishes a flow. In the suspicious person detection information display process, based on the "detection date", "suspicious person position", "camera position", "imaging direction", and "suspicious person image" of the suspicious person detection notification, The display unit 33 displays a suspicious person detection screen indicating the camera position and imaging direction in which the monitoring image including the suspicious person is captured, the position of the suspicious person, and the date and time of detection of the suspicious person. Therefore, the display unit 33 corresponds to display means in claims.

  As an example, as shown in FIG. 19, an image indicating the position of a house A (see A in FIG. 19) and a monitoring area (see the hatched portion in FIG. 19) is displayed, and an icon ( 19) and an icon indicating the position of the suspicious person (see E in FIG. 19). In addition, a text indicating the date and time of detection of the suspicious person such as “The intrusion of the suspicious person was detected at 00:15 on December 30” is also displayed. Furthermore, when the icon indicating the suspicious person position is selected, an image of the suspicious person (see F in FIG. 20) is displayed as shown in FIG.

  According to this, by notifying the user of the abnormal state, it becomes possible to reduce the risk that the user does not notice the abnormal situation and encounters a suspicious person. In addition, since the icon indicating the camera position and imaging direction in which the monitoring image including the suspicious person is captured is displayed, the user can quickly understand the sense of direction when viewing the suspicious person image. This makes it possible to quickly take a crime prevention action or an evacuation action when the person is accidentally located near the monitoring area.

  Note that the positions of the house A (see A in FIG. 19) and the monitoring area (see the hatched portion in FIG. 19) are positional information on the house A and the monitoring area stored in the nonvolatile memory of the terminal-side control unit 35 in advance. It is sufficient to adopt a configuration using In addition, the location information of the house A and the monitoring area is included in the suspicious person information response message and the suspicious person detection message, and the location information of the house A and the monitoring area is also included in the suspicious person detection notification. By doing so, it may be configured to use the position information of the house A and the monitoring area included in the suspicious person detection notification.

  The monitoring center 2 also generates a suspicious person movement route notification in addition to the suspicious person detection notification based on the received suspicious person information response message and the suspicious person detection message, and transmits it to the user terminal 3 of the resident of the house A. It is good also as composition to do.

  For example, as shown in FIG. 21, the suspicious person movement route notification includes information on “detection date and time” indicating the detection date and time of the suspicious person and “suspicious person position” indicating the position of the suspicious person. More specifically, it includes information on “detection date” and “suspicious person position” included in each suspicious person information response message and suspicious person detection message.

  The user terminal 3 of the resident of the house A that has received the suspicious person detection notification and the suspicious person movement path notification transmitted from the monitoring center 2 by the terminal side communication unit 31 performs a suspicious person movement path notification process. The suspicious person movement route notification process is the same process as the above-described suspicious person detection notification process (steps S51 to S53) except that the suspicious person's movement route is displayed. Hereinafter, only differences from the above-described suspicious person detection notification process will be described.

  In the suspicious person movement route notification process, in addition to the image of the suspicious person, the camera position and imaging direction in which the monitoring image including the suspicious person is imaged, the position of the suspicious person, the detection date and time of the suspicious person, the movement path of the suspicious person A suspicious person movement route screen is also displayed on the display unit 33. The travel route is created by connecting the “suspicious person location” in the order of “detection date” based on the combination of multiple “detection date” and “suspicious person location” included in the suspicious person travel route notification. And it is sufficient.

  As an example, as shown in FIG. 22, an image indicating the position of a house A (see A in FIG. 22) and a monitoring area (see the hatched portion in FIG. 22) is displayed, and an icon ( 22) and an icon indicating the suspicious person position (see E in FIG. 22). In addition, a text indicating the date and time of detection of the suspicious person such as “The intrusion of the suspicious person was detected at 00:15 on December 30” is also displayed. Further, the movement route (see G in FIG. 22) is also displayed.

  According to this, it becomes possible to grasp where the suspicious person has entered from. Moreover, it becomes possible to introduce a system with a higher crime prevention level by grasping the intrusion route of the suspicious person.

  In addition, it is preferable that the suspicious person movement route notification is transmitted (reported) to a server device of an organization that performs public duties or services related to security. According to this, in a security service organization such as the police or security company, in order to grasp the gait before entering the surveillance area of the suspicious person and the gait after the escape, information useful for the clearance of the suspicious person is automatically As a result, the local crime prevention level can be increased.

  Further, when the suspicious person information response message and the suspicious person detection message are configured not to include “camera position” and “imaging direction”, the suspicious person detection notification also includes “camera position” and “imaging direction”. Alternatively, the user terminal 3 may be configured not to display the image indicating the camera position and the imaging direction in which the monitoring image including the suspicious person is captured.

  According to the configuration of the first embodiment, when generating a suspicious person information response message including a suspicious person image, the amount of data of the suspicious person information response message can be reduced by narrowing down according to the collection period, the collection area, and the suspicious person characteristics. . This makes it possible to prevent congestion in the wireless communication path, reduce the influence on other wireless communication, and make it possible to effectively use the communication band.

  In addition, since the data capacity of the suspicious person response message is reduced according to the number of surrounding vehicles, for example, in a region where there are many vehicles such as Ginza, congestion in the wireless communication is suppressed, and the influence on other wireless communication is reduced. It is possible to suppress the communication bandwidth and make effective use of the communication band. As a result, the reliability of communication can be improved for a radio access scheme such as CSMA / CA.

  Furthermore, according to the configuration of the first embodiment, the fixed monitoring device 1a and the in-vehicle monitoring device 1b regularly take a monitoring image, and the past date and time is included in the “collection period” included in the suspicious person information request message. By designating, it is possible to collect monitoring images before the suspicious person enters the monitoring area. Thereby, for example, when a suspicious person parks a vehicle somewhere and enters the monitoring area, vehicle information of the suspicious person can be collected together with the suspicious person, so that the suspicious person can be cleared more easily. Therefore, the local crime prevention effect can be further enhanced.

  In the present embodiment, when a suspicious person is detected by the fixed monitoring apparatus 1a, a suspicious person information request message is transmitted to the in-vehicle monitoring apparatus 1b, and a suspicious person information response message is received (collected) from the in-vehicle monitoring apparatus 1b. Thus, although the configuration for transmitting the collected suspicious person information response message and the suspicious person detection message to the monitoring center 2 has been shown, the present invention is not necessarily limited thereto.

  For example, when a suspicious person is detected by the fixed monitoring apparatus 1a, a suspicious person information request message is transmitted to a fixed monitoring apparatus 1a other than the own apparatus (that is, another), and a suspicious person information response is sent from another fixed monitoring apparatus 1a. The message may be received (collected), and the collected suspicious person information response message and the suspicious person detection message may be transmitted to the monitoring center 2.

  In addition, when a suspicious person is detected by the in-vehicle monitoring device 1b, a suspicious person information request message is transmitted to the in-vehicle monitoring device 1b or the fixed monitoring device 1a other than the own device (that is, other), and other in-vehicle monitoring is performed. The suspicious person information response message may be received (collected) from the device 1a or the fixed monitoring device 1a, and the collected suspicious person information response message and the suspicious person detection message may be transmitted to the monitoring center 2. Therefore, the monitoring control device 15b also corresponds to the feature extraction unit, the request generation unit, the request transmission unit, and the monitoring device side transmission unit in the claims.

  Moreover, it is good also as a structure which transmits a suspicious person information request message to the monitoring center 2 from the monitoring apparatus 1 (fixed monitoring apparatus 1a and vehicle-mounted monitoring apparatus 1b). Then, the monitoring center 2 transmits the suspicious person information request message to the monitoring apparatus 1 around the monitoring apparatus 1 that is the transmission source of the suspicious person information request message, collects the suspicious person information response message at the monitoring center 2, and It is good also as a structure which performs a report and notification.

  In addition, from the monitoring center 2 to the user terminal 3 around the monitoring device 1 that is the transmission source of the suspicious person information request message (that is, the user terminal 3 in the surrounding area where the suspicious person is detected), It is good also as a structure which transmits information including a person's image and alerts the surrounding area where the suspicious person was detected. As an example, a configuration may be adopted in which alerting is performed by displaying the presence of a suspicious person, a suspicious person position, and a suspicious person image.

  In the fixed monitoring device 1a, when it is determined that a suspicious person exists when a monitoring image including a person is obtained, if there is a person in the monitoring area, there is a person in the monitoring area. It is good also as a structure which performs machine learning about the case where it does not carry out. The start and end of the machine learning may be configured in accordance with a user instruction using the user terminal 3 or the like.

  As an example, it is assumed that machine learning is performed by using an image of an actual camera 12a when a person is present in the monitoring area as a correct image and an image of the actual camera 12a when a person is not present in the monitoring area as an incorrect image. That's fine. According to this, the accuracy of the suspicious person detection from the monitoring image can be increased according to the installation location of the camera 12a.

  Further, in the fixed monitoring device 1a, when the camera position and the optical axis direction of the camera 12a are fixed, the pixel of the monitoring image region used for the suspicious person presence / absence determination processing may be designated. Even when the camera position and the direction of the optical axis of the camera 12a are variable, the same target is obtained after the pixels of the monitoring image region used for the suspicious person presence / absence determination processing are specified for a certain camera position and imaging direction. A configuration may be adopted in which pixels are automatically changed in accordance with changes in the camera position and imaging direction so that the region is always designated.

  According to this, since it becomes possible to limit the area to be monitored to a specific area such as a warehouse or a parking lot entrance / exit, it is necessary for suspicious person presence determination processing (that is, detection of suspicious person). The amount of calculation can be reduced, and the power consumption of the fixed monitoring device 1a can be reduced. Moreover, since the area where the image recognition process is performed is limited, the load of the image recognition process can be reduced, and the response speed of the suspicious person presence determination process can be improved.

(Embodiment 2)
The present invention is not limited to the above-described embodiment, and the following second embodiment is also included in the technical scope of the present invention. Hereinafter, the second embodiment will be described. For convenience of explanation, members having the same functions as those shown in the drawings used in the description of the above-described embodiment are denoted by the same reference numerals, and description thereof is omitted.

  As shown in FIG. 23, the monitoring area monitoring system 200 includes an in-vehicle monitoring device 1b, a monitoring center 2, and a user terminal 3. The monitoring area monitoring system 200 has the same configuration as the monitoring area monitoring system 100 of the first embodiment except that the fixed monitoring device 1a is not included.

  In the present embodiment, as shown in FIG. 23, the monitoring area monitoring system 200 includes a case where the vehicle-mounted monitoring device 1b of the vehicle B1, the vehicle-mounted monitoring device 1b of the vehicle B2, the monitoring center 2, and the user terminal 3 are taken as an example. To explain.

  The communication between the communication device 11b of the in-vehicle monitoring device 1b and the monitoring center 2 uses a communication module used for telematics communication such as DCM, a mobile phone connected by Bluetooth (registered trademark) communication, etc. H reference) may be used.

  In the in-vehicle monitoring device 1b, as described above, the monitoring area is set in a garden or a parking lot around a building in the site of a house or the like to be watched (a house A in this example), and the house to be watched over What is necessary is just to make it detect the suspicious person who invaded the garden in the site, such as a parking lot, or a parking lot (refer FIG. 24). It is assumed that the monitoring image is captured by the camera 12b sequentially even outside the monitoring area.

  Next, an example of a processing flow in the monitoring area monitoring system 200 will be described with reference to the sequence diagram of FIG. Here, a case where a suspicious person is detected by the in-vehicle monitoring device 1b of the vehicle B1 will be described as an example. In addition, the user terminal 3 demonstrates as what is used for the resident of the house A.

  First, the user terminal 3 performs terminal side watching setting processing (t101). Here, an outline of the terminal-side watching setting process will be described using the flowchart of FIG. The flow of FIG. 26 is started when the user terminal 3 is activated by turning on the power of the user terminal 3 or the like.

  In step S101, the terminal-side control unit 35 determines whether there is a setting action from the user. For example, what is necessary is just to set it as the structure which determines with the setting action from a user, when the user input which sets the monitoring area and monitoring period about the house A is received by the operation input part 34. FIG. The monitoring period is composed of a monitoring start date and time and a monitoring end date and time. Therefore, the terminal-side control unit 35 corresponds to the user setting unit in the claims.

  If it is determined that there is a setting action (YES in step S101), the process proceeds to step S102. On the other hand, when it is determined that there is no setting action (NO in step S101), the flow of step S101 is repeated.

  In step S102, the terminal-side control unit 35 performs watch setting message generation processing, and proceeds to step S103. In the watch setting message generation process, a watch setting message is generated based on the set monitoring area and monitoring period. Therefore, the process in step S102 corresponds to a setting message generation unit in the claims.

  For example, as shown in FIG. 27, the watch setting message includes information on “monitoring start date and time” indicating the start date and time of the monitoring period, “monitoring end date and time” indicating the end date and time of the monitoring period, and “monitoring area” indicating the monitoring area. Become.

  The monitoring area is represented by, for example, a closed circuit connecting a plurality of coordinates (latitude, longitude, and altitude in this example). The information of the “monitoring area” included in the watch setting message is expressed by the plurality of coordinates. It shall be. The “monitoring start date / time”, “monitoring end date / time”, and “monitoring area” may be configured to use the monitoring area and the monitoring period set by the user operation.

  In step S103, the terminal-side control unit 35 performs a watch setting message transmission process, and returns to step S101. In the watching setting message transmission process, the terminal side control unit 35 causes the terminal side communication unit 31 to transmit the watching setting message generated in the watching setting message generation process to the monitoring center 2. Therefore, the terminal-side control unit 35 corresponds to a setting transmission unit in claims.

  Returning to FIG. 25, when the monitoring area and the monitoring period are set in the user terminal 3 of the resident of the house A, a watch setting message is transmitted from the user terminal 3 to the monitoring center 2 via the base station (t102). .

  The monitoring setting message returned from the user terminal 3 is received by the center side communication unit 21 of the monitoring center 2. Therefore, the center side communication part 21 is equivalent to the setting reception means of a claim. The monitoring center 2 that has received the watching setting message transmits (transfers) the received watching setting message from the center side communication unit 21 to the in-vehicle monitoring device 1b of the vehicle B1 in accordance with an instruction from the center side control unit 23 (t103). Therefore, the center side control part 23 is equivalent to the center side transfer means of a claim.

  Note that the user terminal 3 of the resident of the house A and the vehicle-mounted monitoring device 1b of the vehicle B1 are associated with each other in advance, for example, when setting a vehicle to watch over the house A. What is necessary is just to make it the structure made possible by linking and registering with the non-volatile memory of the control part 23.

  The watch setting message transmitted from the monitoring center 2 is received by the communication device 11b of the in-vehicle monitoring device 1b of the vehicle B1. The monitoring control unit 15b of the in-vehicle monitoring device 1b that has received the watch setting message performs an automatic setting process (t104). In the automatic setting process, the monitoring area specified in the received monitoring setting message is automatically set in the monitoring area of the own device, and the monitoring period specified in the setting message is automatically set as the monitoring period of the own device. Therefore, the monitoring control unit 15b corresponds to the automatic setting unit in the claims.

  It is assumed that the in-vehicle monitoring device 1b of the vehicle B1 is automatically activated with the accessory (ACC) power-on of the vehicle B1, engine driving, power supply of a traveling battery such as EV and PHV, etc. as triggers.

  In the in-vehicle monitoring device 1b in which the monitoring area and the monitoring period specified by the watch setting message are set, the above-described monitoring related processing is performed according to this setting (t105). As a specific example, a monitoring image that satisfies the following two conditions is extracted from the monitoring images stored in the monitoring DB 14b, and the above-described suspicious person detection related processing is performed. The first point is that the imaging date and time is included in the set monitoring period. The second point is that the camera position is a predetermined distance or less from the monitoring area. The predetermined distance here may be, for example, the maximum shooting distance of the camera 12b.

  When a suspicious person is detected by the in-vehicle monitoring device 1b of the vehicle B1, a suspicious person information response message similar to the above-described suspicious person information response message is generated, and the monitoring control unit 15b transmits the suspicious person information response message to the monitoring center 2 from the communication device 11b. (T106). In the second embodiment, an image of an area including at least a suspicious person detected by the suspicious person presence determination process may be extracted from the monitoring image stored in the monitoring DB 14b as information of the “suspicious person image”.

  Further, the monitoring center 2 receives the suspicious person information response message transmitted from the in-vehicle monitoring device 1b of the vehicle B1 by the center side communication unit 21, and based on the received suspicious person information response message, the center side control unit 23 The above-described suspicious person detection notification generation process is performed (t107).

  Then, the suspicious person detection notification generated by the suspicious person detection notification generation process is transmitted (reported) from the center side control unit 23 to the server device of the organization that performs public service or service related to security (t108). The monitoring center 2 transmits (notifies) the generated suspicious person detection notification to the user terminal 3 of the resident of the house A (t109).

  The user terminal 3 of the resident of the house A that has received the suspicious person detection notification transmitted from the monitoring center 2 by the terminal-side communication unit 31 performs the above-described suspicious person detection notification process based on the received suspicious person detection notification. (T110).

  In this embodiment, although the structure which sets the monitoring area and monitoring time limit of one vehicle was shown, it is not necessarily this, By transmitting a watch setting message to the vehicle-mounted monitoring apparatus 1b of several vehicles, multiple It is good also as a structure which sets the monitoring area and monitoring time limit of one vehicle.

  Even in the configuration of the second embodiment, since the suspicious person information response message including the suspicious person image is generated, narrowing is performed based on the collection period, the collection area, and the suspicious person characteristics.

  Furthermore, according to the configuration of the second embodiment, the user can change the monitoring area and the monitoring deadline of the in-vehicle monitoring device 1b freely and in real time through the monitoring center 2 by performing an operation input to the user terminal 3. Is possible. Therefore, it becomes possible to set the monitoring area and the monitoring deadline for each of the plurality of in-vehicle monitoring devices 1b freely and in real time, and the monitoring service in the entire region can be made efficient.

  Further, the fixed monitoring device 1a may be configured such that the monitoring area and the monitoring period can be changed from the user terminal 3 via the monitoring center 2 in the same manner as described above.

  The present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the claims, and the technical means disclosed in different embodiments can be appropriately combined. Such embodiments are also included in the technical scope of the present invention.
