It is considered that this control is also a function control related to the position information transmission in the drive recorder 1 based on the area information. The function control processing unit 17b acquires the latitude and longitude information of the vertices at both ends of the line segment defining the boundary line as the boundary information, and transmits the position information to the server device 5 at the timing when the line segment is approached.

Next, the server device 5 will be described with reference to FIG. The server device 5 includes an area information storage unit 51, a communication unit 52, a control unit 53, and the like.

Therefore, it is understood by those skilled in the art that these functional blocks can be realized in various forms by combining hardware and software.

The area information storage unit 51 divides a country, a region, or the like into individual areas, and stores area information in the divided areas. The area information storage unit 51 stores, for example, the position of the boundary line of the area and the area information about the image recording restriction in the area in association with each other. Further, the boundary line is defined by, for example, a plurality of connected line segments, and the area information storage unit 51 uses the latitude and longitude information of the vertices at both ends of the plurality of line segments as the boundary line information for each area.

For example, as the area of country A, the latitude and longitude information of the point that becomes the border of country A or the boundary line that becomes the border of country A is comprehensively stored, and the area within the boundary is set as the area of country A, and within A country. It is stored in association with the information about the recording restriction of the image in. For example, if there is a restriction on image recording in country A, information about the restriction is stored. The area information in each divided area may be stored in a list or table format in which the latitude / longitude information is associated with which area the point is, and the area information storage unit 51 may store the area information in any format. A known technique may be used as to whether or not to memorize.

The communication unit 52 is wirelessly or wiredly connected to the communication network 9, and communicates with the communication unit 16 of the drive recorder 1 via the communication network 9.

The control unit 53 includes a position information acquisition unit 53a and an area information processing unit 53b. The control unit 53 is configured by, for example, a CPU or the like, and operates according to a computer program stored in the storage unit 54 to execute the processing by each of the above-mentioned units. The storage unit 54 is composed of a data storage device such as a RAM, a flash memory, and a hard disk storage device, and stores a computer program or the like executed by the control unit 53.

The position information acquisition unit 53a of the control unit 53 acquires the position information transmitted from the drive recorder 1 mounted on the vehicle via the communication unit 52, and transfers the acquired vehicle position information to the area information processing unit 53b. Output.

The area information processing unit 53b obtains the area where the vehicle exists based on the position information of the vehicle acquired by the position information acquisition unit 53a. The area information processing unit 53b extracts the area information about the image recording restriction corresponding to the area where the vehicle exists from the area information storage unit 51. The area information processing unit 53b transmits the extracted area information to the drive recorder 1 via the communication unit 52.

Further, the area information processing unit 53b obtains the boundary closest to the position of the vehicle based on the position information of the vehicle, and transmits the area information including the information of the boundary to the drive recorder 1. The area information processing unit 53b sets the accuracy of boundary information to be transmitted to the drive recorder 1, such as latitude and longitude, according to the distance between the position of the vehicle and the boundary.

The area information processing unit 53b may include the latitude and longitude of the boundary point closest to the position of the vehicle in the area information as the boundary information. Further, the area information processing unit 53b may include the latitude and longitude at the vertices at both ends of the line segment indicating the boundary line closest to the position of the vehicle as the boundary information in the area information. Further, the area information processing unit 53b makes the number of vertices included in the boundary information sent to the drive recorder 1 variable according to the distance between the vehicle position and the boundary.

Next, the operation of the drive recorder 1 will be described based on the image recording control process in the drive recorder 1. FIG. 4 is a flowchart showing the procedure of the image recording control process in the drive recorder 1. The drive recorder 1 acquires the current position information of the vehicle by the position information acquisition unit 17a of the control unit 17 (S1). The function control processing unit 17b transmits the vehicle position information acquired by the position information acquisition unit 17a to the server device 5 via the communication unit 16 (S2). When the server device 5 acquires the position information of the vehicle, the server device 5 obtains the area where the vehicle exists, extracts the area information regarding the image recording restriction in the area from the area information storage unit 51, and transmits the area information to the drive recorder 1.

The function control processing unit 17b of the drive recorder 1 receives and acquires the area information transmitted from the server device 5 via the communication unit 16 (S3). The function control processing unit 17b determines whether or not there is an image recording restriction based on the function restriction information included in the area information (S4). When there is an image recording restriction (S4: YES), the function control processing unit 17b stops the image recording process in the image processing unit 11 (S5), and ends the process. When there is no image recording restriction (S4: NO), the function control processing unit 17b executes the image recording process in the image processing unit 11 (S6), and ends the process.

The drive recorder 1 is based on the area information transmitted from the server device 5, when the vehicle exists in an area where image recording is restricted, when the vehicle exists in an accident-prone area, or when the vehicle is present. When it exists in a tourist spot, it is possible to perform function control such as executing image recording processing and changing the image quality for recording an image.

When the vehicle moves from the area with the image recording restriction to the area without the image recording restriction, the drive recorder 1 can start the recording process of the stopped image. In this way, the drive recorder 1 can execute functional control regarding the stop and start of image recording in the vehicle based on the area information.

Further, in step S5 described above, the function control processing unit 17b may notify the user by the notification unit 15 that the vehicle exists in the area where the image recording is restricted. The function control processing unit 17b may stop the image recording processing when the user selects to stop the image recording processing by the operation input unit 14 as a result of the notification.

Further, the function control processing unit 17b notifies the user that the vehicle has moved to the area without the image recording restriction when moving from the area with the image recording restriction to the area without the image recording restriction by the notification unit 15. You may try to do it. The function control processing unit 17b may start the image recording processing when the user selects to start the image recording processing by the operation input unit 14 as a result of the notification.

The function control processing unit 17b controls the timing of transmitting the vehicle position information based on the boundary information included in the area information. FIG. 5 is a schematic diagram for explaining the timing of position information transmission. For example, the function control processing unit 17b sets the timing of transmitting the vehicle position information once an hour when the distance Lb is 100 km, and sets the vehicle position information when the distance Lb is 1 km. The timing of transmission may be once per minute. When the boundary point closest to the vehicle position is included in the area information, the function control processing unit 17b obtains the distance Lb between the vehicle position when the previous area information was acquired and the closest boundary point. , The timing of transmitting the position information of the vehicle is determined according to the distance Lb. For example, the function control processing unit 17b obtains the time required to reach the boundary of the area based on the distance Lb and the vehicle speed acquired via the input / output interface 13, and then determines the timing for transmitting the position information. The drive recorder 1 stops the transmission of position information until there is a possibility of moving from the area where the vehicle exists to another area, and aims to reduce the communication traffic and the processing amount in the server device 5. Can be done.

The function control processing unit 17b obtains the distance Ln between the position of the vehicle at the time of the previous transmission of the position information obtained by acquiring the area information about the distance Lb and the current position of the vehicle, and when the distance Lb is reached or the distance. The transmission timing may be determined so that the position information is transmitted when the position information is close to Lb.

Further, when the area information includes the information of the boundary line closest to the position of the vehicle, the function control processing unit 17b has the vehicle based on the vehicle position at the time of the previous acquisition of the area information and the information of the boundary line. The timing of transmitting the position information of the above to the server device 5 is determined. When the area information includes the latitude and longitude at the vertices at both ends of the line segment indicating the boundary line closest to the vehicle position, the area information processing unit 53b approaches the line segment defined based on the vertices. It is the timing to transmit the position information of the vehicle to the server device 5.

When the latitude and longitude of two or more vertices are included in the area information, the timing is set to transmit the vehicle position information to the server device 5 when approaching each line segment defined based on each vertex.

Next, the operation of the server device 5 will be described based on the area information processing in the server device 5. FIG. 6 is a flowchart showing the procedure of area information processing in the server device 5. The position information acquisition unit 53a of the server device 5 acquires the position information of the vehicle from the drive recorder 1 (S11). The area information processing unit 53b identifies the area where the vehicle exists based on the position information of the vehicle (S12).

The area information processing unit 53b extracts area information about the image recording restriction in the area where the vehicle exists from the information stored in the area information storage unit 51 (S13). The area information processing unit 53b extracts information on the boundary closest to the position of the vehicle based on the position information of the vehicle (S14). The area information processing unit 53b transmits the area information including the information of the boundary closest to the position of the vehicle to the drive recorder 1 via the communication unit 52 (S15).

Further, the area information processing unit 53b obtains the boundary closest to the position of the vehicle based on the position information of the vehicle, and includes the information of the boundary in the area information. In the drive recorder 1, the transmission timing of the position information can be appropriately determined based on the boundary information included in the area information, and the processing efficiency in the server device 5 becomes good.

Further, the area information processing unit 53b appropriately selects, for example, a map having a scale of 1 / 500,000 from a map having a scale of 1 / 10,000 according to the distance between the position of the vehicle and the boundary, and sends the map to the drive recorder 1. Sets the accuracy of boundary information, such as latitude and longitude. As a result, the server device 5 can appropriately set the accuracy of the timing at which the position information is transmitted on the drive recorder 1 side.

The area information processing unit 53b may include the latitude and longitude of the boundary point closest to the position of the vehicle in the area information as the boundary information. As a result, the server device 5 can set the timing of transmitting the position information on the drive recorder 1 side based on the information of the position of the vehicle and the boundary point.

Further, the area information processing unit 53b may include the latitude and longitude at the vertices at both ends of the line segment indicating the boundary line closest to the position of the vehicle as the boundary information in the area information. In this case, the server device 5 can set the timing for transmitting the position information when the drive recorder 1 approaches the boundary line.

Further, the area information processing unit 53b makes the number of vertices included in the boundary information sent to the drive recorder 1 variable according to the distance between the vehicle position and the boundary. If the distance between the position of the vehicle and the boundary is a close position such as 2 km, the server device 5 combines not only the closest boundary line but also the information of the vertices for defining a plurality of boundary lines around the boundary line. It is possible to transmit and determine the transmission timing of the position information on the drive recorder 1 side in more detail.

(Modification example)
The server device 5 may hold a map including area boundaries or road information, and improve the accuracy of vehicle position estimation by collating with the vehicle position information received from the drive recorder 1 and performing map matching correction. ..

In the above-described embodiment, the drive recorder 1 executes the control related to the image recording limit. However, the server device 5 holds the setting information related to the image recording limit, and the drive recorder 1 includes the setting information in the area information. It may be sent to. The setting information regarding the image recording restriction is, for example, information for setting whether to automatically or manually restrict the image recording on the drive recorder 1 and information for instructing the start or stop of recording.

Further, the area information held by the server device 5 may be information on a dangerous area such as an accident-prone area. When it is determined that the position of the vehicle has entered the area, the area information is transmitted to the drive recorder 1 so as to automatically start shooting and recording. When the drive recorder 1 receives the area information, it notifies the user that the shooting and recording processing is started even when the shooting and recording processing is stopped, and when the user performs an operation to allow it, or in advance. Starts shooting and recording processing when the user has set permission.

Further, the drive recorder 1 has a form in which arbitrary area information such as an area where an accident, a disaster, a power failure, etc. has occurred by a user's operation, that is, an area where traffic damage such as so-called road rage occurs frequently, can be transmitted to the server device 5. May be good. The server device 5 stores the received information as dangerous area information in the area information storage unit 51. It is preferable that the area information included in the server device 5 is appropriately updated to maintain the latest state in the case of area information related to the occurrence of a disaster.

Further, by periodically transmitting the position of the vehicle from the drive recorder 1 to the server device 5, the server device 5 may analyze the route or area on which the vehicle equipped with the drive recorder 1 frequently travels. The server device 5 transmits area information to the drive recorder 1 so as to automatically start shooting and recording processing when the position of the vehicle exists in a route or area where the vehicle frequently travels.

When the drive recorder 1 receives the area information, it notifies the user that the shooting and recording processing is started even when the shooting and recording processing is stopped, and when the user performs a permission operation or the user performs a permission operation in advance. Shooting and recording processing is started when permission is set.

On the contrary, if the route or area is frequently traveled, the shooting may be stopped at all times. This is because it is not often the case that an image of a route that is frequently traveled is reproduced and confirmed. It should be noted that the information on the frequently traveled routes and areas may be held in the internal recording device or the external recording device of the drive recorder 1 instead of being held by the server device 5.

An external recording device or recording medium that holds information about a route or area on which a vehicle equipped with the drive recorder 1 frequently travels may be connected to or attached to a different drive recorder 1 for use. The drive recorder 1 can acquire information on a frequently traveled route or area from a connected or mounted recording medium or the like and transmit it to the server device 5.

In addition to the drive recorder 1 (or vehicle) that is normally used, the service form can be such that the user can use information on the route or area on which the vehicle frequently travels.

The server device 5 may be configured to periodically update and retain the latest disaster information for each area (or area, etc.). When a disaster warning is issued in the area where the drive recorder 1 exists, the area information includes the information and is transmitted to the drive recorder 1. The drive recorder 1 notifies the user of disaster information.

The drive recorder operation system 100 including the server device 5 can also provide a service for transmitting disaster information and the like to the user in addition to the information related to the image recording control of the drive recorder 1. Further, in the area where the disaster information is present, the drive recorder 1 may automatically start the shooting and recording process.

Next, the features of the server device 5, the area information processing method, and the area information processing program according to the embodiment and the modified example will be described.
The server device 5 includes a position information acquisition unit 53a and an area information processing unit 53b. The position information acquisition unit 53a acquires the position information transmitted from the drive recorder 1 that records the image of the surroundings of the vehicle on the recording medium 12. The area information processing unit 53b obtains the area where the vehicle exists based on the position information, and sends the information of the boundary closest to the vehicle among the boundaries related to the area to the drive recorder 1. As a result, the server device 5 can send out area information for performing function control related to image recording in the vehicle, and the processing efficiency in the server device 5 becomes good by determining the transmission timing in the drive recorder 1. ..

Further, the area information processing unit 53b sets the accuracy of the information to be transmitted to the drive recorder 1 according to the distance between the position of the vehicle and the boundary. As a result, the server device 5 can appropriately set the accuracy of the timing at which the position information of the vehicle is transmitted on the drive recorder 1 side.

In addition, the area boundary information includes the latitude and longitude of the boundary point closest to the position of the vehicle. As a result, the server device 5 can set the timing of transmitting the position information on the drive recorder 1 side based on the information of the position of the vehicle and the boundary point.

The boundary of the area is defined by a plurality of connected line segments. Boundary information includes latitude and longitude at the vertices at both ends of the line segment indicating the closest boundary to the vehicle's position. As a result, the server device 5 can set the timing for transmitting the position information when the drive recorder 1 approaches the boundary line.

Further, the area information processing unit 53b makes the number of lines indicating the boundary included in the information transmitted to the drive recorder variable according to the distance between the position of the vehicle and the boundary. As a result, the server device 5 uses the drive recorder 1 based on the information of the vertices for defining not only the closest boundary line but also the boundary line around the vehicle, for example, when the distance between the position of the vehicle and the boundary line is short. The transmission timing of the position information can be determined in more detail on the side.

Further, the area information processing method includes a position information acquisition step and an area information processing step. The position information acquisition step acquires position information transmitted from the drive recorder 1 that records an image of the surroundings of the vehicle on the recording medium 12. The area information processing step obtains an area in which the vehicle exists based on the position information, and sends information on the boundary closest to the vehicle among the boundaries related to the area to the drive recorder 1. According to this area information processing method, it is possible to send out area information for performing function control related to image recording in a vehicle, and the processing efficiency in the server device 5 is good by determining the transmission timing in the drive recorder 1. Become.

Further, the area information processing program causes the computer to execute the position information acquisition step and the area information processing step. The position information acquisition step acquires position information transmitted from the drive recorder 1 that records an image of the surroundings of the vehicle on the recording medium 12. The area information processing step obtains an area in which the vehicle exists based on the position information, and sends information on the boundary closest to the vehicle among the boundaries related to the area to the drive recorder 1. According to this area information processing program, it is possible to send out area information for performing function control related to image recording in a vehicle, and the processing efficiency in the server device 5 is good by determining the transmission timing in the drive recorder 1. Become.

For example, the server device 5 stores only the position information such as the latitude and longitude of each divided area as the area information, and only the information on which area the vehicle exists based on the position information transmitted by the drive recorder 1. May be transmitted to the drive recorder 1. The drive recorder 1 may perform function control such as changing the image quality setting of image recording based on the area information transmitted from the server device 5. For example, when the server device 5 receives the area information that the vehicle exists in the accident-prone area, the image recording with a high image frame rate may be performed. In this case, the drive recorder 1 has information on what kind of function control is to be performed based on the area information, and it is preferable that this information can be arbitrarily changed by the user.
