[0009] Hereinafter, embodiments for carrying out the present invention (hereinafter referred to as embodiments) will be described with reference to the drawings. Note that the present invention is not limited by the embodiments described below. Further, in the description of the drawings, the same parts are denoted by the same reference numerals.

[0010] [First Embodiment] [1. Overview] First, an overview of the monitoring device 100 according to the embodiment will be described. The monitoring device 100 is a device that records data obtained by imaging a moving object and erases the recorded data under predetermined conditions. Here, an example of the problems of the prior art will be described with reference to FIG. 1. FIG. 1 is a diagram for explaining an example of the problems of the prior art. Conventionally, in order to prevent acts such as automobile theft, vandalism in the vehicle, and vehicle damage to a parked vehicle, the parked vehicle has been monitored. In a device or the like for monitoring a parked vehicle in this way, when a moving object enters a predetermined distance range from the vehicle, recording (saving to a non-volatile memory) around the vehicle is performed, but there are cases where the recorded data before an abnormality occurs cannot be saved.

[0011] For example, conventionally, as shown in FIG. 1, when a moving object invaded the range where it was possible to cause harm to a vehicle, recording was performed upon detection. However, when recording was started triggered by the invasion of a moving object into the range where it was possible to cause harm to the vehicle, there was a problem that only the data immediately before the crime could be recorded. On the other hand, when the recording range was expanded, a large amount of data other than criminal acts would be included, which would put pressure on the storage capacity of the non-volatile memory for storing data.

[0012] Therefore, the monitoring device 100 determines the invasion of a moving object into the first section centered on the vehicle, and when it is determined that an invasion has occurred, the moving object is imaged and the imaged data is saved (recorded). Then, centered on the vehicle, it determines the invasion of a moving object into the second section that is narrower than the first section, and when it is determined that the moving object has not invaded the second section, the data of the moving object imaged and saved at a predetermined timing is deleted. Thereby, the monitoring device 100 can save the recording data before the occurrence of an abnormality.

[0013] 〔2. Configuration of the Monitoring Device〕 Next, the monitoring device 100 according to the embodiment will be described with reference to FIG. 2. FIG. 2 is a diagram showing a configuration example of the monitoring device 100 according to the embodiment. As shown in FIG. 2, the monitoring device 100 includes a communication unit 110, a storage unit 130, and a control unit 120. Hereinafter, each unit included in the monitoring device 100 will be described.

[0014] The communication unit 110 is realized, for example, by a NIC (Network Interface Card) or the like. The communication unit 110 is connected to the network N by wire or wirelessly, and performs information transmission and reception with, for example, the in-vehicle device 10.

[0015] The storage unit 130 is implemented by, for example, a semiconductor memory element such as a RAM (Random Access Memory) or a flash memory, or a storage device such as a hard disk or an optical disk. The storage unit 130 stores the position where the moving body sensor is installed, the intensity of the signal to be transmitted, the sensitivity to receive the signal, the intensity of the received signal, the angle calculated from the received signal, the distance, the coordinates of the moving body, the imaging data, the traveling direction, various thresholds, the mounting position of the moving body sensor, information related to notifications (notification settings, notification destination terminal information, address information, etc.), images (including moving images and still images), and other information necessary for determining the entry / exit of the moving body and storing / erasing the imaging data.

[0016] The control unit 120 is implemented using a CPU (Central Processing Unit), an NP (Network Processor), an FPGA (Field Programmable Gate Array), etc., and executes a processing program stored in the memory. As shown in FIG. 2, the control unit 120 includes a sensor unit 121, a first determination unit 122, a storage unit 123, a second determination unit 124, a third determination unit 125, a deletion unit 126, a modification unit 127, and a notification unit 128. Hereinafter, each unit included in the control unit 120 will be described.

[0017] The sensor unit 121 detects (acquires) information using various sensors. For example, the sensor unit 121 detects a moving body using a moving body sensor such as a distance sensor, a microwave sensor, or LiDAR (light detection and ranging). Also, the sensor unit 121 detects the position of the vehicle using a positioning sensor such as a GNSS (Global Navigation Satellite System) sensor or a GPS (Global Positioning System) sensor. Further, the sensor unit 121 detects the acceleration of the vehicle using an acceleration sensor. Also, for example, the sensor unit 121 detects the angular velocity of the vehicle using a gyro sensor. Also, for example, the sensor unit 121 acquires an image (moving image / still image) around the vehicle using an imaging device.

[0018] Here, as an example of the installation location of the sensors included in the sensor unit 121, the moving object sensor is installed at parts inside and outside the vehicle according to the purpose, such as the front pillar, center pillar, rear pillar, interior mirror, side mirror, ceiling, seat, rear glass, etc.

[0019] The first determination unit 122 determines the intrusion of a moving object into a first section centered on the vehicle. For example, the first determination unit 122 determines whether a moving object detected by the sensor unit 121 functioning as a moving object sensor has intruded into a first section centered on the vehicle. For example, the first determination unit 122 analyzes the signal received by the sensor unit 121 functioning as a moving object sensor, and determines whether the moving object has intruded into a first section centered on the vehicle from the information on distance and angle.

[0020] In addition to the above, the first determination unit 122 can determine the intrusion of a moving object into the first section using the information on the signal intensity. For example, the first determination unit 122 analyzes the signal received by the sensor unit 121 functioning as a moving object sensor, and determines whether the moving object has intruded into a first section centered on the vehicle from the information on distance, angle, and signal intensity. That is, the first determination unit 122 determines that the moving object has intruded into the first section when the distance and angle of the signal received by the moving object sensor satisfy the conditions and the signal intensity exceeds a predetermined threshold value.

[0021] Here, the range of the first section will be described with reference to FIG. 3. FIG. 3 is a diagram showing an example of the ranges of the first section and the second section. The first section may be a range at a predetermined distance from the vehicle as shown in FIG. 3(1). More specifically, the first section is a range of 4 m from the vehicle. Also, for example, the first section may be a range in which a predetermined distance is set for each of the front, side, and rear of the vehicle. More specifically, the first section is a range of 3 m from the front and rear of the vehicle and 4 m from the side of the vehicle.

[0022] The storage unit 123 stores (records) data obtained by imaging a moving object. For example, the storage unit 123 uses the imaging device included in the sensor unit 121 to image the moving object and stores the imaged data. That is, the storage unit 123 records the image captured by the imaging device. Here, the recording process by the storage unit 123 will be described. The captured imaging data is first stored in a temporary storage memory such as a ring buffer. The imaging data stored in the temporary storage memory is sequentially updated with the latest data, and the imaging data from the past is retained for a set period of time. Thereafter, the storage unit 123 performs a recording process by storing the imaging data stored in the temporary storage memory in a non-volatile memory.

[0023] For example, when the first determination unit 122 determines that a moving object has entered the first section, the storage unit 123 stores the data obtained by imaging the moving object in a non-volatile memory. That is, the storage unit 123 starts recording when the moving object enters the first section. On the other hand, in response to the start of recording, the storage unit 123 may end the recording when the moving object exits the first section. For example, when the third determination unit 125 described below determines that the moving object has exited the first section, the storage unit 123 ends the storage of the data obtained by imaging the moving object.

[0024] For example, when a moving object enters the first section and then exits the first section, first, the storage unit 123 starts recording the imaging data to the SD card at the timing when the first determination unit 122 determines that the moving object has entered the first section. Thereafter, the storage unit 123 ends the recording of the imaging data to the SD card at the timing when the third determination unit 125 determines that the moving object has exited the first section.

[0025] The second determination unit 124 determines whether a moving object has entered a second section that is narrower than the first section, with the vehicle at the center. For example, the second determination unit 124 determines whether a moving object detected by the sensor unit 121 functioning as a moving object sensor has entered a second section that is narrower than the first section, with the vehicle at the center. For example, the second determination unit 124 analyzes the signal received by the sensor unit 121 functioning as a moving object sensor, and determines whether the moving object has entered a second section that is narrower than the first section centered on the vehicle, based on information about the distance and the angle.

[0026] In addition to the above, the second determination unit 124 can determine whether a moving object has entered the second section by using information about the signal strength. For example, the second determination unit 124 analyzes the signal received by the sensor unit 121 functioning as a moving object sensor, and determines whether the moving object has entered a second section that is narrower than the first section centered on the vehicle, based on information about the distance, the angle, and the signal strength. That is, the second determination unit 124 determines that the moving object has entered the second section when the distance and the angle of the signal received by the moving object sensor satisfy the conditions and the signal strength exceeds a predetermined threshold value.

[0027] Here, the range of the second section will be described with reference to FIG. 3. FIG. 3 is a diagram showing an example of the ranges of the first section and the second section. The second section may be a predetermined distance range from the vehicle, as shown in FIG. 3(2). More specifically, the second section is a range of 2 m from the vehicle. Further, for example, the second section may be a range in which a predetermined distance is set for each of the front, side, and rear surfaces of the vehicle. More specifically, the second section is a range of 1 m from the front and rear surfaces of the vehicle and 2 m from the side surfaces of the vehicle.

[0028] The third determination unit 125 determines whether a moving object has exited from the first section. For example, the third determination unit 125 determines whether a moving object detected by the sensor unit 121 functioning as a moving object sensor has exited from the first section centered on the vehicle. For example, the third determination unit 125 analyzes the signal received by the sensor unit 121 functioning as a moving object sensor, and determines whether the moving object has exited from the first section centered on the vehicle, based on information about the distance and the angle.

[0029] In addition to the above, the third determination unit 125 can determine the exit of a moving object from the first section using information on the signal strength. For example, the third determination unit 125 analyzes the signal received by the sensor unit 121 that functions as a moving object sensor, and determines whether the moving object has exited from the first section centered on the vehicle based on information on the distance, angle, and signal strength. That is, the third determination unit 125 determines that the moving object has exited from the first section when the distance and angle of the signal received by the moving object sensor satisfy the conditions and the signal strength is below a predetermined threshold value.

[0030] When it is determined by the first determination unit 122 that an intrusion has occurred and it is determined by the second determination unit 124 that there is no intrusion, the erasure unit 126 erases the data obtained by imaging the moving object stored by the storage unit 123 at a predetermined timing. For example, when it is determined by the first determination unit 122 that a moving object has intruded into the first section and it is determined by the second determination unit 124 that the moving object has not intruded into the second section, the erasure unit 126 erases the data obtained by imaging the moving object stored by the storage unit 123 from the non-volatile memory at a predetermined timing. Here, for example, the predetermined timing is the time point when a predetermined time has elapsed since the accessory of the vehicle was turned off (accessory power OFF). More specifically, the predetermined timing is the time point when 6 hours have elapsed since the accessory of the vehicle was turned off.

[0031] Also, for example, the predetermined timing is the time point when the power supply voltage supplied to the monitoring device 100 becomes equal to or lower than a predetermined threshold value. More specifically, the predetermined timing is the time point when the power supply voltage supplied to the monitoring device 100 becomes less than 4.0V. Also, for example, the predetermined timing is the time point when the accessory of the vehicle is turned on (accessory power ON).

[0032] Also, for example, the predetermined timing is the timing when the moving object has exited from the first determination unit 122. That is, the erasure unit 126 erases the recorded data of the moving object that has intruded into the first section and has not intruded into the second section from the non-volatile memory at the above-described predetermined timing.

[0033] The changing unit 127 changes one or more ranges of the first section and the second section. For example, the changing unit 127 changes one or more ranges of the first section and the second section according to user settings. For example, the changing unit 127 changes the range of the first section to 3 m and the range of the second section to 1 m according to a user setting where the range of the first section is 3 m and the range of the second section is 1 m.

[0034] Also, for example, the changing unit 127 changes one or more ranges of the first section and the second section according to the date and time. More specifically, the changing unit 127 changes the range of the first section to 5 m and the range of the second section to 3 m during a time period with less pedestrian traffic (for example, from 23:00 to 5:00). Also, for example, the changing unit 127 changes one or more ranges of the first section and the second section according to the location. More specifically, the changing unit 127 changes the range of the first section to 3 m and the range of the second section to 1 m in a location where congestion is predicted. Note that for predicting the congestion situation for each location, for example, the current or past location information of a user terminal such as a smartphone or a vehicle can be used.

[0035] The notification unit 128 gives a predetermined notification based on the moving object detected by the sensor unit 121. For example, when the moving object detected by the sensor unit 121 and the vehicle are in a predetermined positional relationship (for example, within a predetermined distance), the notification unit 128 notifies a pre-registered user terminal that a moving object is approaching the vehicle. Note that notifications to the user terminal include those that can be made using functions provided by the user terminal, such as emails, incoming calls, and notifications to an application. At this time, the notification unit 128 may transmit an image captured by the imaging device to the user terminal.

[0036] Also, for example, when the moving object detected by the sensor unit 121 and the vehicle are in a predetermined positional relationship (for example, within a predetermined distance), the notification unit 128 issues an alarm by sound or light around the vehicle using a speaker or a light.

[0037] [3. Processing of the Monitoring Device] Next, an example of the processing by the monitoring device 100 will be described with reference to FIG. 4. FIG. 4 is a diagram for explaining an example of the processing by the monitoring device 100. FIG. 4(1) shows an example in which a moving body (human) enters the first section and the second section and then exits from the first section.

[0038] As shown in FIG. 4(1), when the moving body enters the first section, the first determination unit 122 determines that the moving body has entered the first section. Then, the storage unit 123 captures an image of the moving body and starts recording the captured data. Subsequently, as shown in FIG. 4(1), when the moving body enters the second section, the second determination unit 124 determines that the moving body has entered the second section.

[0039] Subsequently, as shown in FIG. 4(1), when the moving body exits from the first section, the third determination unit 125 determines that the moving body has exited from the first section. Here, since the storage unit 123 has been determined by the third determination unit 125 that the moving body has exited from the first section, the storage unit 123 ends the recording of the data obtained by imaging the moving body. In the example of FIG. 4(1), since the second determination unit 124 has determined that the moving body has entered the second section, the data obtained by imaging the moving body is not deleted.

[0040] Thereby, the monitoring device 100 starts recording triggered by the entry of the moving body into the first section, and ends the recording of the data obtained by imaging the moving body at the timing when the moving body exits from the third section, so that the recording data before the occurrence of the abnormality can be saved.

[0041] Next, FIG. 4(2) shows an example in which the moving body enters only the first section and then exits from the first section. As shown in FIG. 4(2), when the moving body enters the first section, the first determination unit 122 determines that the moving body has entered the first section. The storage unit 123 captures an image of the moving body and starts recording the captured data. Subsequently, as shown in FIG. 4(2), when the moving body has not entered the second section, the second determination unit 124 determines that the moving body has not entered the second section.

[0042] Then, as shown in FIG. 4(2), when the moving object exits the first section, the third determination unit 125 determines that the moving object has exited the first section. Here, since the storage unit 123 determines that the moving object has exited the first section by the third determination unit 125, the storage unit 123 ends the recording of the data obtained by imaging the moving object.

[0043] In the example of FIG. 4(2), since the deletion unit 126 determines that the moving object has not entered the second section by the second determination unit 124, the deletion unit 126 deletes the data obtained by imaging the moving object stored by the storage unit 123 at a predetermined timing.

[0044] Thereby, the monitoring device 100 deletes the recording data that is not necessary for storage by deleting the recording data in which the moving object has not entered the range where the moving object can cause harm to the vehicle at a predetermined timing (for example, when the vehicle's accessory is turned on), and can secure the storage capacity of the storage medium.

[0045] [4. Flowchart] Next, the processing by the monitoring device 100 having the above-described configuration will be described with reference to the flowchart of FIG. 5. The flowchart of FIG. 5 is mainly executed by the control unit 120. Further, this flowchart can be configured as a program executed by the CPU included in the control unit 120 to obtain a monitoring program. Note that the following steps can also be executed in a different order, and there may be processes that are omitted.

[0046] First, the change unit 127 changes one or more ranges of either the first section or the second section (step S101). For example, the change unit 127 changes one or more ranges of either the first section or the second section according to user settings. Subsequently, the sensor unit 121 detects a moving object using a moving object sensor (step S102). For example, the sensor unit 121 detects a moving object using a moving object sensor such as a distance sensor, a microwave sensor, or LiDAR.

[0047] Subsequently, the first determination unit 122 determines whether or not the moving object detected by the sensor unit 121 functioning as a motion sensor has entered a first section centered on the vehicle (step S103). Here, when the first determination unit 122 determines that the moving object has not entered the first section (step S103: No), the process of step S102 is performed again.

[0048] On the other hand, when the first determination unit 122 determines that the moving object has entered the first section (step S103: Yes), the storage unit 123 starts recording (step S104). For example, when the first determination unit 122 determines that the moving object has entered the first section, the storage unit 123 stores the data obtained by imaging the moving object in a non-volatile memory.

[0049] Subsequently, the third determination unit 125 determines the exit of the moving object from the first section (step S105). For example, the third determination unit 125 determines whether or not the moving object detected by the sensor unit 121 functioning as a motion sensor has exited from the first section centered on the vehicle.

[0050] Here, when the third determination unit 125 determines that the moving object has not exited from the first section (step S105: No), the process of step S105 is performed again. On the other hand, when the third determination unit 125 determines that the moving object has exited from the first section (step S105: Yes), the storage unit 123 ends the recording (step S106). For example, the storage unit 123 ends the storage of the data obtained by imaging the moving object in the non-volatile memory.

[0051] Subsequently, the second determination unit 124 determines the entry of the moving object into a second section centered on the vehicle and narrower than the first section (step S107). For example, the second determination unit 124 determines whether or not the moving object detected by the sensor unit 121 functioning as a motion sensor has entered the second section centered on the vehicle and narrower than the first section during the period from when the moving object enters the first section until it exits. Here, when the second determination unit 124 determines that the moving object has entered the second section (step S107: Yes), the monitoring device 100 ends the process.

[0052] On the other hand, when the second determination unit 124 determines that the moving object has not entered the second section (step S107: No), subsequently, the deletion unit 126 determines whether it is a predetermined timing (step S108). For example, as an example of the predetermined timing, the deletion unit 126 determines whether a predetermined time has elapsed since the vehicle accessory was turned off.

[0053] Here, when the deletion unit 126 determines that it is not the predetermined timing (step S108: No), the process of step S108 is performed again. On the other hand, when the deletion unit 126 determines that it is the predetermined timing (step S108: Yes), the deletion unit 126 deletes the recorded data (step S109). For example, the data obtained by imaging the moving object stored by the storage unit 123 is deleted. Then, the monitoring device 100 ends the process.

[0054] 〔5. Effect〕 The monitoring device 100 according to the embodiment includes a first determination unit 122 that determines the intrusion of a moving object into a first section centered on the vehicle, a storage unit 123 that images the moving object and stores the imaged data when the first determination unit 122 determines that the object has intruded, a second determination unit 124 that determines the intrusion of a moving object into a second section centered on the vehicle and narrower than the first section, and a deletion unit 126 that deletes the data obtained by imaging the moving object stored by the storage unit 123 at a predetermined timing when the second determination unit 124 determines that the object has not intruded.

[0055] Thereby, the monitoring device 100 can start recording when a moving object enters the first section, and can save the recorded data before the abnormality occurs. In addition, the monitoring device 100 deletes the recorded data in which the moving object has not entered the second section, thereby deleting the recorded data that is not necessary to be saved because the moving object has not entered the range where it can cause harm to the vehicle, and can secure the storage capacity of the storage medium.

[0056] The monitoring device 100 according to the embodiment further includes a third determination unit 125 that determines the exit of a moving object from the first section. When the third determination unit 125 determines that the moving object has exited, the storage unit 123 ends the storage of the data obtained by imaging the moving object.

[0057] As a result, when a moving object enters the first section, the monitoring device 100 starts recording, and when the moving object exits the first section, the monitoring device 100 ends the recording, so that recording is also performed for the period before the moving object enters the range where harm can be done to the vehicle, and the recording data before the occurrence of an abnormality can be stored.

[0058] In the monitoring device 100 according to the embodiment, the predetermined timing is the time point when a predetermined time has elapsed since the vehicle accessory was turned off. As a result, the monitoring device 100 deletes the recording data at the timing when a predetermined time has elapsed since the vehicle accessory was turned off, so that, for example, after getting off the vehicle, the storage capacity of the storage medium can be ensured in accordance with the timing when the monitoring device 100 operates in an energy-saving manner.

[0059] In the monitoring device 100 according to the embodiment, the predetermined timing is the time point when the power supply voltage supplied to the monitoring device 100 becomes equal to or lower than a predetermined threshold value. As a result, the monitoring device 100 deletes the recording data at the timing when the power supply voltage supplied to the monitoring device 100 becomes equal to or lower than a predetermined threshold value, so that, for example, when the operation of the monitoring device 100 ends, the storage capacity of the storage medium can be ensured.

[0060] In the monitoring device 100 according to the embodiment, the predetermined timing is the time point when the vehicle accessory is turned on. As a result, the monitoring device 100 deletes the recording data at the timing when the vehicle accessory is turned on, so that, for example, when getting into the vehicle, the storage capacity of the storage medium can be ensured.

[0061] The monitoring device 100 according to the embodiment further includes a changing unit 127 that changes one or more ranges of the first section and the second section according to user settings. Thereby, the monitoring device 100 changes the ranges of the first section and the second section according to user settings, thereby changing the range that triggers recording at the time of intrusion and the range determined not to be erased, and can appropriately store necessary recording data.

[0062] The monitoring device 100 according to the embodiment further includes a changing unit 127 that changes one or more ranges of the first section and the second section according to the date and time. Thereby, the monitoring device 100 changes the ranges of the first section and the second section according to the date and time, thereby changing the range that triggers recording at the time of intrusion and the range determined not to be erased, and can appropriately store necessary recording data.

[0063] The monitoring device 100 according to the embodiment further includes a changing unit 127 that changes one or more ranges of the first section and the second section according to the location. Thereby, the monitoring device 100 changes the ranges of the first section and the second section according to the location, thereby changing the range that triggers recording at the time of intrusion and the range determined not to be erased, and can appropriately store necessary recording data.

[0064] [Modification Example] [1. System Configuration] So far, an example in which the monitoring according to the first embodiment is realized only by the monitoring device 100 provided in the vehicle has been described. Hereinafter, a modification example of the above embodiment will be described. As a modification example, an example in which the monitoring according to the first embodiment is realized by the monitoring device 100 existing on the cloud and the in-vehicle device 10 provided in the vehicle communicating with each other will be described. FIG. 6 is a diagram showing the configuration of a monitoring system according to the embodiment. In FIG. 6, a monitoring system 1 is shown as an example of a monitoring system according to the embodiment. Note that descriptions of the content common to the first embodiment will be omitted as appropriate.

[0065] As shown in FIG. 6, the monitoring system 1 includes an in-vehicle device 10 and a monitoring device 100. The in-vehicle device 10 and the monitoring device 100 are communicably connected by wire or wirelessly via a network N. Also, the monitoring system 1 shown in FIG. 6 may include any number of in-vehicle devices 10 and any number of monitoring devices 100.

[0066] Here, if the in-vehicle device 10 is an edge computer that performs edge processing near the user, the monitoring device 100 may be, for example, a cloud computer that performs processing on the cloud side. That is, the monitoring device 100 may be a server device. As shown in FIG. 6, in the present invention, the monitoring according to the embodiment is realized in the monitoring system 1 by transmitting and receiving information between the monitoring device 100, which is a server device existing on the cloud, and the in-vehicle device 10 provided in the vehicle.

[0067] The in-vehicle device 10 may be a dedicated sensor device built in or externally attached to the vehicle VEx, or may be a device such as a recording device (drive recorder) installed in the vehicle VEx for crime prevention or countermeasures against aggressive driving.

[0068] Also, the in-vehicle device 10 may be composed of a sensor device and a notification device. As an example of this, the in-vehicle device 10 may be a composite device in which a sensor device and a notification device that are independent of each other are communicably connected. Also, as another example, the in-vehicle device 10 may be a single device having a sensor function and a notification function.

[0069] Also, the user can substitute this by connecting a predetermined sensor to a portable terminal device (for example, a smartphone, a tablet-type terminal, a notebook PC, a desktop PC, a PDA, etc.) that is used daily and introducing a predetermined application. For example, a portable terminal device provided with a predetermined sensor or to which a predetermined sensor is connected can be regarded as the in-vehicle device 10 here. When the portable terminal device is utilized as the in-vehicle device 10, it is installed, for example, on the dashboard of the vehicle VEx during driving.

[0070] In addition, the in-vehicle device 10 may be provided with various sensors. For example, the in-vehicle device 10 may be provided with a distance sensor, a moving object sensor such as a microwave sensor or a LiDAR, a temperature sensor, a microphone, a positioning sensor such as a GNSS sensor or a GPS sensor, an acceleration sensor, a gyro sensor, an imaging device such as a camera, and various sensors such as a barometric pressure sensor.

[0071] The monitoring device 100 may acquire various data based on the sensor information detected by these sensors (for example, by analyzing the sensor information). For example, the monitoring device 100 acquires information on moving objects inside and outside the vehicle from the moving object sensor. Also, for example, the monitoring device 100 acquires the temperature inside the vehicle from the temperature sensor. Also, for example, the monitoring device 100 acquires sound from the microphone. Also, for example, the monitoring device 100 acquires the angular velocity from the gyro sensor. Also, for example, the monitoring device 100 acquires data of a moving image obtained by photographing the outside from inside the vehicle VEx by the camera. Note that the monitoring device 100 may acquire the sensor information detected not only by the sensors provided in the in-vehicle device 10 but also by the sensors provided in the vehicle VEx itself.

[0072] [Others] [1. Hardware Configuration] In addition, the monitoring device 100 according to the above-described embodiment is realized, for example, by a computer 1000 having a configuration as shown in FIG. 7. FIG. 7 is a hardware configuration diagram showing an example of a computer that realizes the functions of the monitoring device 100. The computer 1000 includes a CPU 1100, a RAM 1200, a ROM 1300, an HDD 1400, a communication interface (I / F) 1500, an input / output interface (I / F) 1600, and a media interface (I / F) 1700.

[0073] The CPU 1100 operates based on programs stored in the ROM 1300 or the HDD 1400 and controls each part. The ROM 1300 stores a boot program executed by the CPU 1100 when the computer 1000 starts up, programs dependent on the hardware of the computer 1000, and the like.

[0074] The HDD 1400 stores programs executed by the CPU 1100 and data used by such programs. The communication interface 1500 receives data from other devices via a predetermined communication network, sends it to the CPU 1100, and transmits data generated by the CPU 1100 to other devices via the predetermined communication network.

[0075] The CPU 1100 controls output devices such as a display and a printer and input devices such as a keyboard and a mouse via the input / output interface 1600. The CPU 1100 acquires data from the input devices via the input / output interface 1600. Also, the CPU 1100 outputs the generated data to the output devices via the input / output interface 1600.

[0076] The media interface 1700 reads a program or data stored in the recording medium 1800 and provides it to the CPU 1100 via the RAM 1200. The CPU 1100 loads such a program from the recording medium 1800 onto the RAM 1200 via the media interface 1700 and executes the loaded program. The recording medium 1800 is, for example, an optical recording medium such as a DVD (Digital Versatile Disc), a PD (Phase change rewritable Disk), a magneto-optical recording medium such as an MO (Magneto-Optical disk), a tape medium, a magnetic recording medium, or a semiconductor memory.

[0077] For example, when the computer 1000 functions as the monitoring device 100 according to the embodiment, the CPU 1100 of the computer 1000 realizes the functions of the control unit 120 by executing the program loaded on the RAM 1200. The CPU 1100 of the computer 1000 reads and executes these programs from the recording medium 1800. As another example, these programs may be acquired from other devices via a predetermined communication network.

That is, those skilled in the art can implement various modifications without departing from the gist of the present invention in accordance with conventionally known knowledge. As long as the monitoring device of the present invention is included even by such modifications, of course, it is included in the scope of the present invention.
