Embodiment 1
Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing a configuration of the operation information recording system 300 according to the first embodiment. The operation information recording system 300 includes an in-vehicle device 100 and a server 200. The in-vehicle device 100 and the server 200 are connected to the network 400. The network 400 may be wired or wireless. The driving information recording system 300 may include a plurality of in-vehicle devices 100. The server 200 receives the excellent driving information described later from the in-vehicle device 100 and records it in the database.

FIG. 2 is a block diagram showing a functional configuration of the in-vehicle device 100. The in-vehicle device 100 is a device mounted on a vehicle and determining the excellent driving of the driver of the vehicle. The in-vehicle device 100 includes an acquisition unit 101, a detection unit 102, a determination unit 103, and a transmission unit 104. The acquisition unit 101 sequentially acquires the first photographed image of the outside of the vehicle. The acquisition unit 101 may acquire, for example, each frame included in the moving image as a first captured image.

The detection unit 102 detects a predetermined detection target from the first captured image. The predetermined detection target is, for example, a traffic sign indicating that a stop is to be performed, a deceleration signal displayed by a traffic light, a person waiting at the end of a pedestrian crossing, or the like. The detection unit 102 uses a known image recognition technique when detecting a detection target.

When the detection unit 102 detects a predetermined detection target, the determination unit 103 determines whether or not the vehicle has decelerated or stopped based on the time change of the first captured image. For example, the determination unit 103 determines that the vehicle has decelerated or stopped when the time change of the first captured image is sufficiently small. Further, when the predetermined detection target is a traffic sign, the determination unit 103 may determine that the vehicle has decelerated or stopped when the change in the detection position of the traffic sign is sufficiently small.

The transmission unit 104 transmits excellent operation information based on the determination result of the determination unit 103 to the server. The transmission unit 104 transmits, for example, the number of times the vehicle has decelerated or stopped as excellent driving information to the server. Further, the transmission unit 104 may transmit the fact that the vehicle has decelerated or stopped to the server 200 as excellent driving information, and may have the server 200 record the number of times the vehicle has decelerated or stopped. Further, the transmission unit 104 may transmit excellent driving information and identification information of the driver who drives the vehicle to the server. The identification information is, for example, a driver's license number, an address, a name, and the like.

As mentioned above, until now, it has not been possible to properly evaluate the excellent driving of each driver. The vehicle-mounted device 100 according to the first embodiment determines whether or not the vehicle has decelerated or stopped, and transmits excellent driving information based on the determination result. Therefore, the driving information recording system 300 can appropriately evaluate the driver's excellent driving based on the excellent driving information received by the server 200. Since the in-vehicle device 100 determines the excellent operation, the determination process, the reception process of the captured image, and the like in the server 200 are unnecessary.

The in-vehicle device 100 includes a processor, a memory, and a storage device as a configuration (not shown). Further, the storage device stores a computer program in which the processing of the transmission method according to the present embodiment is implemented. Then, the processor reads the computer program from the storage device into the memory and executes the computer program. As a result, the processor realizes the functions of the acquisition unit 101, the detection unit 102, the determination unit 103, and the transmission unit 104.

Alternatively, the acquisition unit 101, the detection unit 102, the determination unit 103, and the transmission unit 104 may each be realized by dedicated hardware. Further, a part or all of each component of each device may be realized by a general-purpose or dedicated circuitry, a processor, or a combination thereof. These may be composed of a single chip or may be composed of a plurality of chips connected via a bus. A part or all of each component of each device may be realized by the combination of the circuit or the like and the program described above. Further, as a processor, a CPU (Central Processing Unit), a GPU (Graphics Processing Unit), an FPGA (field-programmable gate array), or the like can be used.

In other words, the camera image input unit 111 stores a photographed image showing a road sign or the like and a driver's face image.

The control unit 110 controls the entire operation of the in-vehicle device 100a by controlling each component and the exchange of data between the components. The detection unit 112 detects a predetermined detection target from the first captured image by automatic recognition. The determination unit 113 determines whether or not the vehicle equipped with the in-vehicle device 100a has decelerated or stopped based on the time change of the first captured image.

The first recording processing unit 117 records the number of times the vehicle has decelerated or stopped based on the determination result of the determination unit 113. The number of times is also called excellent driving information. The first recording processing unit 117 may start recording excellent driving information according to the success of the first face recognition described later.

The transmission unit 114 controls communication with the server 200a via the network 400. The transmission unit 114 transmits the license number 11 and the excellent driving information recorded by the first recording processing unit 117 to the server 200a. Here, the transmission unit 114 may transmit excellent driving information to the server 200a according to the success of the second face recognition described later. The transmission unit 114 may transmit the excellent operation information every day, or may transmit the excellent operation information when the operation is started or ended.

The authentication unit 115 performs face recognition based on the driver's license face image 12 for the second captured image. In other words, the authentication unit 115 collates the second photographed image with the license face image 12 and authenticates whether or not the driver is the person described in the license. The authentication unit 115 may perform the first face recognition before starting the recording of the excellent driving information and the second face recognition before transmitting the excellent driving information. In addition, in order to prevent forgery of the license, the authentication unit 115 collates the license number 11 and the license face image 12 with the license number and the license face image stored in the IC chip of the license and confirms that they match. It has a function to authenticate whether or not it is.

The server 200a includes a control unit 210, a reception unit 211, a processing unit 212, and an operation history DB (Data Base) 220. The control unit 210 controls the entire operation of the server 200a by controlling each component and the exchange of data between the components.

The receiving unit 211 controls communication with the in-vehicle device 100a via the network 400. The receiving unit 211 receives the license number 11 and the excellent driving information from the in-vehicle device 100a. The processing unit 212 records the license number 11 and the excellent driving information in the operation history DB 220 in association with each other. The processing unit 212 is also referred to as a second recording processing unit.

The server 200a may be connected to a terminal (not shown) installed in a license center or the like. The terminal can authenticate a user using a license, present excellent driving information to the user, and print excellent driving information. The business operator may provide various services to the driver based on the excellent driving information at the time of license renewal or license return.

Further, the business operator may certify the degree of safe driving of each driver based on the driving history DB 220 and apply a discount to the automobile insurance premium of the driver. Further, the business operator may secure a good driver in the physical distribution field based on the operation history DB 220.

Next, the operation of the operation information recording system 300a according to the second embodiment will be described with reference to FIG. It is assumed that the driver sets the driver's license on the scanner 10 which is a card reader. First, the driver's license information input unit 116 reads the driver's license number 11 and the driver's license face image 12 from the driver's license (step S101).

Next, the authentication unit 115 collates the license number 11 stored in the license information input unit 116 with the license number stored in the IC chip of the license, and if they match, the license face image 12 And the driver's license face image stored in the IC chip of the driver's license are collated. If the collation is successful, the authentication unit 115 collates the license face image 12 with the second captured image stored in the camera image input unit 111 (step S102). If the collation is successful, the in-vehicle device 100a starts recording the excellent driving information. In other words, if the collation is successful, the in-vehicle device 100a activates each function for determining good operation.

Next, the detection unit 112 detects a predetermined detection target from the first captured image stored in the camera image input unit 111 (step S103). Next, the determination unit 113 determines whether or not the vehicle has decelerated or stopped based on the time change of the first captured image (step S104). Next, when the vehicle decelerates or stops, the first recording processing unit 117 records the driving as excellent driving (step S105).

For example, the detection unit 112 detects the stop sign. Then, the determination unit 113 determines that the vehicle has been temporarily stopped for a certain period of time when the first photographed image does not change for a certain period of time. In such a case, the first recording processing unit 117 records the operation as a good operation. The determination unit 113 may determine the stop based on the change in the position of the stop sign in the first captured image.

Further, the detection unit 112 may detect a yellow signal. The determination unit 113 determines that the vehicle has decelerated when the change in the first captured image is sufficiently small. In such a case, the first recording processing unit 117 records the operation as a good operation. The in-vehicle device 100a may perform the above-mentioned operation when the yellow traffic light is blinking.

Further, the detection unit 112 may detect a person waiting at the end of the pedestrian crossing. The determination unit 113 determines that the vehicle has temporarily stopped when the first captured image does not change for a certain period of time. In such a case, the first recording processing unit 117 records the operation as a good operation.

It is assumed that the excellent driving information is recorded in the in-vehicle device 100a by the above-mentioned operation. As described above, good driving is the number of times the vehicle is paused at the stop sign, the number of times the vehicle is decelerated at the yellow traffic light, the number of times the vehicle is stopped when there is a person stopped at the pedestrian crossing, and the like.

The authentication unit 115 collates the second captured image stored in the camera image input unit 111 with the driver's license face image 12 (step S106). If the collation is successful, the transmission unit 114 transmits the license number 11 and the excellent driving information to the server 200a (step S107). Here, the transmission unit 114 may transmit driver information such as a name and an address read from the license as identification information. Finally, the receiving unit 211 of the server 200a receives the license number 11 and the excellent driving information, and the processing unit 212 of the server 200a registers the license number 11 and the excellent driving information in the operation history DB 220 in association with each other. Step S108).

It is assumed that the driver holds the license over the terminal installed in the license center, etc. and enters the password. When the driver succeeds in inputting the password, the terminal acquires the excellent driving information associated with the license number from the server 200a and prints the excellent driving information (step S109). The driver will be able to receive services at the license center by presenting the printed information.

Hereinafter, the effects of this embodiment will be described. In driving a car, traffic violations such as road rage and traffic accidents of the elderly have become social problems. It is required to improve the driving manners of drivers and comply with traffic rules, but malicious driving is occasionally seen every day. There are various mechanisms for cracking down on traffic violations, such as automatic crackdown devices and inspections, but it was difficult to catch a person who committed a traffic violation outside a specific location.

On the other hand, there is also a mechanism to encourage drivers who comply with traffic rules. However, it is considered that the mechanism for judging good driving is insufficient. This is because you can get a gold card for a driver's license, which is a proof of good driving, without driving. Also, the person who violated the traffic may not have been caught by chance.

The in-vehicle device 100a according to the second embodiment can determine and encourage a driver who observes traffic rules and keeps in mind good driving. Further, the in-vehicle device 100a according to the second embodiment may increase the number of people who aspire to good driving, promote safe driving, and further reduce traffic accidents.

Further, according to the second embodiment, the third party can appropriately evaluate the driving of each driver based on the number of times of good driving. In addition, since it is possible to provide various services based on the number of good driving times, it is considered that the value of performing good driving can be increased.

The present invention is not limited to the above embodiment, and can be appropriately modified without departing from the spirit. For example, the in-vehicle device 100a may read the My Number card instead of the driver's license. In such a case, the in-vehicle device 100a may be mounted on a bicycle or the like instead of an automobile.
