[0009] (Configuration of Information Processing System) Hereinafter, an information processing device and a program according to an embodiment will be described in detail with reference to the accompanying drawings. Note that the present invention is not limited to the embodiment.

[0010] First, an information processing system 1 according to the embodiment will be described with reference to Fig. 1. Fig. 1 is a block diagram showing an example of the configuration of the information processing system 1 according to the embodiment.

[0011] The information processing system 1 includes a data collection device 2 and an information processing device 3. The data collection device 2 and the information processing device 3 are communicatively connected to each other via a communication network N such as the Internet. In the information processing system 1, a plurality of data collection devices 2 are communicatively connected to the information processing device 3.

[0012] The data collection device 2 is, for example, an in-vehicle device. The in-vehicle device is, for example, a drive recorder. Here, a case where the data collection device 2 is the drive recorder 2 will be described as an example.

[0013] The drive recorder 2 includes an on-board camera (not shown). The on-board camera includes, for example, a lens and an imaging element. The imaging element is a charge coupled device (CCD) or a complementary metal oxide semiconductor (CMOS). The on-board camera is provided in a position capable of capturing images of the front, rear, left and right sides of the vehicle, for example. A plurality of on-board cameras may be provided. The on-board camera captures images of the surroundings of the vehicle. The on-board camera acquires images of the surroundings of the vehicle. The images are moving images.

[0014] The drive recorder 2 collects data related to vehicle events. The data related to vehicle events includes at least one of data related to vehicle accidents and data related to dangerous driving.

[0015] Vehicle accidents include collisions between the vehicle and another vehicle, self-damage accidents involving the vehicle, and collisions between the vehicle and a person.

[0016] Dangerous driving is driving that does not result in a vehicle accident but may lead to a vehicle accident. For example, dangerous driving includes sudden braking and sudden steering.

[0017] The data related to a vehicle event includes data that is a triggering factor of the vehicle event. The triggering factor of the vehicle event is a factor that can be a cause of the event when the vehicle event occurs. The triggering factor of the vehicle event is, for example, the color of the traffic light, the speed state of the vehicle, and the brake operation state of the vehicle. Note that the triggering factor of the vehicle event includes at least one of the color of the traffic light, the speed state of the vehicle, and the brake operation state of the vehicle.

[0018] The drive recorder 2 identifies a traffic light by, for example, executing a predetermined image processing based on image data obtained by capturing an image using an in-vehicle camera, and further identifies the color of the light of the identified traffic light.

[0019] The drive recorder 2 acquires the vehicle speed from a vehicle speed sensor (not shown) by, for example, CAN communication. The drive recorder 2 judges whether the vehicle complies with the legal speed based on the acquired vehicle speed. That is, the drive recorder 2 judges whether the vehicle's speed state is equal to or lower than the legal speed, i.e., whether the vehicle's speed state is in a legal speed compliance state, i.e., higher than the legal speed, i.e., whether the vehicle's speed state is in a non-legal speed violation state. The drive recorder 2 acquires the legal speed of the road on which the vehicle is traveling based on the vehicle's position information, and judges whether the vehicle complies with the legal speed. The vehicle's position information is received from, for example, a GPS (Global Positioning System) device. The legal speed of the road is stored, for example, in association with map information.

[0020] The drive recorder 2 acquires a signal related to the brake operation state from a brake sensor (not shown) by, for example, CAN communication. The brake operation state includes an operation state in which the brake pedal is depressed and a non-operation state in which the brake pedal is not depressed. For example, when the depression amount of the brake pedal is greater than a predetermined depression amount set in advance, the brake operation state is determined to be an operation state. When the depression amount of the brake pedal is equal to or less than the predetermined depression amount, the brake operation state is determined to be a non-operation state.

[0021] The drive recorder 2 stores data related to vehicle events in association with the date and time when the data was acquired. The drive recorder 2 stores data related to vehicle events for a predetermined storage time. The predetermined storage time is a time set in advance, for example, 10 seconds. When the drive recorder 2 acquires data related to new vehicle events, the drive recorder 2 sequentially erases data related to old vehicle events and updates the data related to vehicle events for the predetermined storage time.

[0022] In addition, the drive recorder 2 stores the vehicle environment data and the vehicle driving data in association with the date and time when the data was acquired. The drive recorder 2 stores the vehicle environment data for a predetermined storage time and the vehicle driving data for a predetermined storage time. The drive recorder 2 updates the vehicle environment data and the vehicle driving data as well as the data related to the vehicle events.

[0023] The vehicle environment data includes weather information and brightness information around the vehicle. The drive recorder 2 acquires weather information from, for example, an external information server (not shown). The drive recorder 2 also acquires brightness information around the vehicle from an illuminance sensor (not shown) via, for example, CAN communication. The vehicle environment data may include temperature.

[0024] The vehicle driving data includes the lighting state of the vehicle's headlights (not shown), the vehicle's speed information, the vehicle's acceleration information, and the vehicle's position information. The drive recorder 2 obtains a signal related to the lighting state of the headlights from a sensor that detects the lighting state of the headlights by, for example, CAN communication. The drive recorder 2 obtains a signal related to the acceleration of the vehicle from an acceleration sensor (not shown) by, for example, CAN communication.

[0025] When a predetermined transmission condition is satisfied, the drive recorder 2 transmits data related to vehicle events for a predetermined storage time, vehicle environmental data for a predetermined storage time, and vehicle driving data for a predetermined storage time to the information processing device 3 via the communication network N. The drive recorder 2 includes a communication device (not shown) for transmitting data related to vehicle events and the like to the information processing device 3. When a predetermined transmission condition is satisfied, the drive recorder 2 transmits data related to vehicle events for a predetermined storage time before and after the time when the predetermined transmission condition is satisfied to the information processing device 3.

[0026] Specifically, when a predetermined transmission condition is satisfied, the drive recorder 2 transmits to the information processing device 3 data relating to vehicle events for a predetermined storage time, vehicle environmental data for a predetermined storage time, vehicle driving data for a predetermined storage time, the date and time when each data was acquired, and image data for the predetermined storage time, linked to a device ID assigned to the drive recorder 2. The device ID is identification information for identifying the drive recorder 2. The device ID may be linked to information about the vehicle in which the drive recorder 2 is mounted, information about the owner of the vehicle, and the like.

[0027] The predetermined transmission condition is a condition for determining that an event has occurred in the vehicle. When the acceleration of the vehicle reaches or exceeds a predetermined acceleration, the drive recorder 2 determines that a vehicle accident has occurred and determines that the predetermined transmission condition is satisfied.

[0028] In addition, when the increase in the brake pedal depression per unit time is equal to or greater than a predetermined increase, the drive recorder 2 determines that a sudden brake operation has occurred and that dangerous driving has occurred. The increase in the brake pedal depression is calculated based on a signal obtained from a brake pedal sensor.

[0029] The drive recorder 2 determines that the steering wheel has been suddenly operated and dangerous driving has occurred when the amount of steering wheel operation per unit time is equal to or greater than a predetermined amount of operation set in advance. The amount of steering wheel operation is detected by, for example, a steering angle sensor (not shown). The drive recorder 2 may determine that the steering wheel has been suddenly operated and dangerous driving has occurred when the vehicle speed is equal to or greater than a predetermined vehicle speed and the amount of steering wheel operation per unit time is equal to or greater than a predetermined amount of operation set in advance.

[0030] (Configuration of information processing device) Next, the information processing device 3 will be described with reference to Fig. 2. Fig. 2 is a block diagram showing an example of the configuration of the information processing device 3 according to the embodiment.

[0031] The information processing device 3 is, for example, a server provided for analyzing the cause of an accident. The information processing device 3 displays the analysis result on a display device 4 (display unit). The information processing device 3 is connected to the display device 4 wirelessly or by wire. The display device 4 is, for example, a monitor. The display device 4 may be a terminal device such as a smartphone.

[0032] The information processing device 3 includes a communication unit 10, a control unit 11, and a storage unit 12.

[0033] The communication unit 10 is realized by, for example, a NIC etc. The communication unit 10 receives data related to vehicle events from the drive recorder 2 via the communication network N.

[0034] The storage unit 12 corresponds to a RAM (Random Access Memory) or a flash memory. The RAM or the flash memory stores information on various programs, data related to vehicle events received by the communication unit 10, and the like.

[0035] The control unit 11 includes an acquisition unit 20, a setting unit 21, a generation unit 22, and an instruction unit 23. The control unit 11 includes, for example, a computer having a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM, a hard disk drive, an input / output port, and various other circuits.

[0036] The CPU of the computer functions as an acquisition unit 20, a setting unit 21, a generation unit 22, and an instruction unit 23 of the control unit 11 by, for example, reading and executing a program stored in a storage device such as a ROM.

[0037] Also, at least a part or all of the acquiring unit 20, the setting unit 21, the generating unit 22, and the instruction unit 23 of the control unit 11 can be configured with hardware such as an ASIC (Application Specific Integrated Circuit) or an FPGA (Field Programmable Gate Array). Also, the acquiring unit 20, the setting unit 21, the generating unit 22, and the instruction unit 23 may be integrated or further divided into a plurality of units.

[0038] The acquisition unit 20 acquires data related to vehicle events and the like via the communication unit 10. The acquisition unit 20 accepts input results from an operator via a keyboard or the like. The operator is, for example, a person who performs analysis of vehicle events using the information processing device 3.

[0039] Specifically, the acquisition unit 20 acquires input related to the vehicle to be analyzed. The acquisition unit 20 accepts, for example, an input result related to the device ID of the vehicle to be analyzed. The input result may be information about the vehicle linked to the device ID, information about the owner, and the like. When there are multiple vehicles to be analyzed, the acquisition unit 20 may accept input results related to multiple vehicles. In addition, the acquisition unit 20 accepts input results related to a display mode, which will be described later.

[0040] Based on the input result, the setting unit 21 sets the display mode to be displayed on the display device 4 to the first display mode or the second display mode. Based on the input result related to the display mode selected by the worker, the setting unit 21 sets the display mode to the first display mode or the second display mode.

[0041] The first display mode is a mode in which occurrence elements of vehicle events are displayed on a map. The second display mode is a mode in which occurrence elements of events are displayed in a graph in chronological order on the display device 4. The display mode can be changed between the first display mode and the second display mode.

[0042] The first display mode also includes a display mode for each occurrence element of a vehicle event. Specifically, the first display mode includes a traffic light display mode, a speed display mode, and a brake operation display mode. The traffic light display mode is a display mode that displays the color of a traffic light. The speed display mode is a display mode that displays the speed state. The brake operation display mode is a display mode that displays the operation state of the brake pedal.

[0043] When the display mode is the first display mode, the setting unit 21 further sets the display mode to any one of a signal display mode, a speed display mode, and a brake operation display mode based on the input result regarding the display mode selected by the operator.

[0044] When the display mode is the first display mode, the setting unit 21 may set a plurality of display modes from among the signal display mode, the speed display mode, and the brake operation display mode based on the input result regarding the display mode selected by the worker. That is, the setting unit 21 can simultaneously set a plurality of display modes from among the signal display mode, the speed display mode, and the brake operation display mode according to the selection by the worker. In this case, the display device 4 displays in the plurality of display modes.

[0045] The generation unit 22 generates display data to be displayed on the display device 4 based on the input result. The display data is data that is displayed as an image on the display device 4. The display data includes data related to the event of the vehicle to be analyzed, etc. Based on the input result, the generation unit 22 reads out data related to the event of the vehicle to be analyzed from the storage unit 12. When there are multiple vehicles to be analyzed, the generation unit 22 reads out data related to the events of each vehicle to be analyzed from the storage unit 12. The generation unit 22 generates display data for the first display mode and display data for the second display mode for the event of the vehicle to be analyzed.

[0046] For example, the display data includes data for displaying a map image including the location where the vehicle event occurred, data for displaying a camera image including the time when the vehicle event occurred, and data for displaying the time when the vehicle event occurred.

[0047] The display data also includes data for displaying the weather when a vehicle event occurs, data for displaying the lighting status of the vehicle being analyzed, and data for displaying the brightness around the vehicle being analyzed.

[0048] The display data for the first display mode includes data for displaying a selected state of a traffic light display mode, a speed display mode, and a brake operation display mode. The display data for the first display mode includes data for displaying a state of an occurrence element of a vehicle event on a map in a different display form according to the state of the occurrence element.

[0049] The display data in the second display mode includes data for displaying the states of occurrence elements of vehicle events in a graph in accordance with the time series of the occurrence elements.

[0050] The instruction unit 23 transmits display data corresponding to the display mode set by the setting unit 21 to the display device 4, and causes the display device 4 to display the display data.

[0051] Specifically, when the display mode is the first display mode, the instruction unit 23 displays the occurrence element of the vehicle event on the map in a different display form according to the state of the occurrence element of the vehicle event.

[0052] Furthermore, when the display mode is the second display mode, the instruction unit 23 displays the occurrence elements of the vehicle event in a graph in chronological order so that the occurrence elements are displayed in different forms according to the state of the occurrence elements of the vehicle event.

[0053] (Image displayed) Next, the display image 100 displayed on the display device 4 based on the display data will be described with reference to Figs. 3 to 6. Fig. 3 is an example of the display image 100 in the signal display form of the first display mode. Fig. 4 is an example of the display image 100 in the speed display form of the first display mode. Fig. 5 is an example of the display image 100 in the brake operation display form of the first display mode. Fig. 6 is an example of the display image 100 in the second display form.

[0054] The display image 100 displayed on the display device 4 based on the display data includes a map 30 of the location where the vehicle event occurred, a video 31 that was captured by the drive recorder 2 and in which the vehicle event was recorded, and a date and time 32 when the vehicle event occurred. The display image 100 displayed on the display device 4 based on the display data also includes the weather 33 when the vehicle event occurred, the lighting state 34 of the vehicle to be analyzed, and the brightness 35 around the vehicle to be analyzed. By displaying the weather 33 when the vehicle event occurred, etc. on the display image 100 of the display device 4, the worker can know the occurrence status of the vehicle event more accurately.

[0055] When there are multiple vehicles to be analyzed, the lighting status of the selected vehicle is displayed as the vehicle lighting status 34. In Fig. 3 and other figures, the selected vehicle is shown in black.

[0056] Moreover, the display image 100 based on the display data of the first display mode includes a selection state 40 of a traffic light display mode, a speed display mode, and a brake operation display mode. Moreover, the display image 100 based on the display data of the first display mode includes an occurrence element of a vehicle event. The occurrence element of a vehicle event in the first display mode is displayed on the map in a different display form according to the state of the occurrence element.

[0057] When the first display mode is the traffic light display mode, lines 50a, 50b indicating the color of traffic lights related to a vehicle event are displayed on the map in a display mode that differs for each color of traffic light, as shown in Fig. 3. The lines 50a, 50b indicating the color of traffic light are displayed on the map in association with the color of the traffic light and the position of the vehicle.

[0058] The lines 50a, 50b indicating the color of the traffic light are displayed in different types according to the color of the traffic light. The lines 50a, 50b indicating the color of the traffic light are displayed, for example, in different types of lines according to the color of the traffic light. Note that the lines 50a, 50b indicating the color of the traffic light may be displayed in different colors, thicknesses, etc. according to the color of the traffic light.

[0059] When the first display mode is the speed display mode, lines 51a, 51b indicating the speed state of the vehicle related to the vehicle event are displayed on the map in different display modes according to the speed state, as shown in Fig. 4. Lines 51a, 51b indicating the speed state of the vehicle are displayed on the map in association with the speed state of the vehicle and the position of the vehicle.

[0060] The lines 51a, 51b indicating the speed state of the vehicle are displayed in a manner distinguishing whether the speed state of the vehicle is in a compliance state or a violation state. The lines 51a, 51b indicating the speed state of the vehicle are displayed, for example, by different types of lines according to the speed state of the vehicle. Note that the lines 51a, 51b indicating the speed state of the vehicle may be displayed in a manner distinguishing, for example, by the color and thickness of the line according to the speed state of the vehicle.

[0061] When the first display mode is the brake operation display mode, lines 52a, 52b indicating the brake operation state of the vehicle related to the vehicle event are displayed on the map in a display form that differs according to the brake operation state, as shown in Fig. 5. The lines 52a, 52b indicating the brake operation state of the vehicle are displayed by lines that associate the brake operation state of the vehicle with the vehicle position.

[0062] The lines 52a, 52b indicating the vehicle's brake operation state are displayed in a differentiated manner depending on whether the vehicle's brake operation state is in an operated state or in an unoperated state. The lines 52a, 52b indicating the vehicle's brake operation state are displayed, for example, by different types of lines depending on the vehicle's brake operation state. Note that the lines 52a, 52b indicating the vehicle's brake operation state may be displayed in a differentiated manner depending on the vehicle's brake operation state, for example, by line color, line thickness, or the like.

[0063] The display image 100 based on the display data in the second display mode includes a graph in which at least a part of the vehicle's travel data is displayed in chronological order. The display image 100 based on the display data in the second display mode also includes a graph in which occurrence elements of vehicle events are displayed in chronological order in different display forms depending on the state of the occurrence elements.

[0064] For example, as shown in FIG. 6, the changes in the speed and acceleration (G value) of a vehicle related to a vehicle event are displayed in a graph along a time series. Note that FIG. 6 shows a diagram in which only the changes in the speed and acceleration of a vehicle selected from among a plurality of vehicles are displayed in a graph, but this is not limited thereto, and the changes in the speed and acceleration of a vehicle that is not selected may also be displayed in a graph. Also, either one of the changes in the speed and acceleration of a vehicle related to a vehicle event may be displayed in a graph along a time series. That is, it is sufficient that at least one of the changes in the speed and acceleration of a vehicle related to a vehicle event is displayed in a graph along a time series.

[0065] In addition, the colors of traffic lights related to vehicle events are displayed in different display forms in a graph along a timeline. The graph display of the colors of traffic lights is displayed with different types of lines according to the colors of the traffic lights. Note that the graph display may be displayed with different colors and thicknesses of lines according to the colors of the traffic lights.

[0066] In addition, the vehicle speed state related to the vehicle event is displayed in a graph in different display forms along a time series. The vehicle speed state is displayed by different types of lines depending on whether it is in a compliance state or a violation state. The vehicle speed state may be displayed by different colors and thicknesses of lines depending on whether it is in a compliance state or a violation state.

[0067] In addition, the vehicle brake operation state related to the vehicle event is displayed in a graph in different display forms along a time series. The vehicle brake operation state is displayed by different types of lines depending on whether it is an operation state or a non-operation state. The brake operation state may be displayed by different colors and thicknesses of lines depending on whether it is an operation state or a non-operation state.

[0068] (Data display processing) Next, the data display process according to the embodiment will be described with reference to the flowchart of Fig. 7. Fig. 7 is a flowchart for explaining the data display process according to the embodiment.

[0069] The information processing device 3 acquires an input related to a vehicle to be analyzed (S100). The information processing device 3 sets a display mode based on the acquired input result (S101). Specifically, the information processing device 3 sets the display mode to the first display mode or the second display mode based on the input result.

[0070] The information processing device 3 generates display data (S102). Specifically, the information processing device 3 reads data related to the event of the vehicle to be analyzed from the storage unit 12 based on the input result, and generates the display data.

[0071] The information processing device 3 transmits the generated display data to the display device 4 (S103). As a result, an image based on the display data is displayed on the display device 4.

[0072] The information processing device 3 may generate display data in the first display mode and display data in the second display mode, and may be able to switch the display mode between the first display mode and the second display mode as appropriate in response to an input from an operator. For example, the information processing device 3 generates display data in the first display mode and display data in the second display mode for a vehicle to be analyzed. Then, the information processing device 3 may switch the image displayed on the display device 4 according to the display mode in response to an operation of switching the display mode by an operator.

[0073] (Effects of the embodiment) Next, effects of the information processing device 3 according to the embodiment will be described.

[0074] The information processing device 3 includes an acquisition unit 20 and an instruction unit 23. The acquisition unit 20 acquires data related to a vehicle event. When the display mode is the first display mode, the instruction unit 23 displays an occurrence element of the vehicle event on the map displayed on the display device 4 in a different display form according to the state of the occurrence element of the event, based on the data related to the vehicle event.

[0075] This allows the worker to check the occurrence factors of the vehicle event on the map displayed on the display device 4, and to easily check the occurrence status of the vehicle event. In other words, the information processing device 3 can improve the efficiency of the work of checking the occurrence status of the vehicle event.

[0076] When the display mode is the first display mode, the information processing device 3 causes the display device 4 to display, on the map, the color of the light of a traffic light related to a vehicle event.

[0077] This allows the worker to easily check on the map the color of the traffic light when a vehicle event occurs. Therefore, the information processing device 3 can improve the efficiency of the work of checking the occurrence status of a vehicle event.

[0078] When the display mode is the first display mode, the information processing device 3 displays the vehicle speed state related to the vehicle event on the map displayed on the display device 4. Specifically, the information processing device 3 displays on the map displayed on the display device 4 whether the vehicle speed state is in compliance or violation.

[0079] This allows the operator to easily check whether the vehicle's speed state is in compliance with or in violation of the vehicle event. Therefore, the information processing device 3 can improve the efficiency of the checking operation for the occurrence status of the vehicle event.

[0080] When the display mode is the first display mode, the information processing device 3 displays the vehicle brake operation state related to the vehicle event on the map displayed on the display device 4. Specifically, the information processing device 3 displays, on the map displayed on the display device 4, whether the vehicle brake operation state is an operated state or a non-operated state.

[0081] This allows the operator to easily check whether the brake operation state of the vehicle is in an operation state or a non-operation state for the vehicle event. Therefore, the information processing device 3 can improve the efficiency of the confirmation work for the occurrence status of the vehicle event.

[0082] The information processing device 3 includes an acquisition unit 20 and an instruction unit 23. The acquisition unit 20 acquires data related to a vehicle event. When the display mode is the second display mode, the instruction unit 23 causes the display device 4 to display, in a graph, an occurrence element of the vehicle event in a time series in a different display form according to a state of the occurrence element of the event, based on the data related to the vehicle event.

[0083] This allows the operator to check the occurrence factors of vehicle events using a graph along a time series, and the operator can easily check the occurrence status of vehicle events along a time series. In other words, the information processing device 3 can improve the efficiency of the work of checking the occurrence status of vehicle events.

[0084] When the display mode is the second display mode, the information processing device 3 causes the display device 4 to display a graph of the color of the light of a traffic light related to a vehicle event.

[0085] This allows the worker to easily check the color of the traffic light in chronological order when a vehicle event occurs, and therefore the information processing device 3 can improve the efficiency of the work of checking the occurrence status of a vehicle event.

[0086] When the display mode is the second display mode, the information processing device 3 displays a graph of the vehicle speed state related to the vehicle event. Specifically, the information processing device 3 displays whether the vehicle speed state is in compliance or violation in chronological order.

[0087] This allows the operator to easily check the vehicle speed information in chronological order when a vehicle event occurs, and therefore the information processing device 3 can improve the efficiency of the work of checking the occurrence status of a vehicle event.

[0088] When the display mode is the second display mode, the information processing device 3 displays a graph of the vehicle brake operation state related to the vehicle event. Specifically, the information processing device 3 displays, on the map displayed on the display device 4, whether the vehicle brake operation state is an operation state or a non-operation state.

[0089] This allows the worker to easily check the vehicle brake operation information in chronological order when a vehicle event occurs. Therefore, the information processing device 3 can improve the efficiency of the work of checking the occurrence status of a vehicle event.

[0090] The information processing device 3 displays the occurrence factors of the vehicle event in a graph together with a time-series graph of at least one of the vehicle speed and the vehicle acceleration.

[0091] This allows the worker to compare the vehicle speed and acceleration with the occurrence factors of the vehicle event in time series, and therefore the worker can easily check the occurrence factors of the vehicle event in time series with respect to at least one of the vehicle speed and acceleration of the vehicle.

[0092] (Modification) The information processing device 3 according to the modified example may simultaneously perform display on the display device 4 based on the display data in the first display mode and the display data in the second display mode. That is, the information processing device 3 according to the modified example may display occurrence elements of a vehicle event on a map displayed on the display device 4, and may also display the occurrence elements of the vehicle event in a graph in chronological order. For example, the information processing device 3 according to the modified example generates display data and transmits the display data to the display device 4 so that the map 30 shown in FIG. 6 is displayed as shown in FIG. 3 to FIG. 5.

[0093] Thereby, the information processing device 3 according to the modified example can improve the efficiency of the work of checking the occurrence status of a vehicle event.

[0094] The information processing device 3 according to the modified example may have only one of the first display mode and the second display mode as the display mode.

[0095] The information processing system 1 according to the modified example may estimate data related to an event of another vehicle from an image acquired by the drive recorder 2 of a certain vehicle. For example, the information processing system 1 according to the modified example may calculate the speed of another vehicle from the other vehicle shown in the image acquired by the drive recorder 2 of a certain vehicle, and estimate the speed of the other vehicle. The information processing system 1 according to the modified example may calculate the speed of another vehicle from the other vehicle shown in the curve mirror of the image acquired by the drive recorder 2 of a certain vehicle, and estimate the speed of the other vehicle. Similarly, the information processing system 1 according to the modified example may estimate the color of the light of a traffic light in the traveling direction of the other vehicle.

[0096] As a result, the information processing device 3 in the modified example can display the occurrence elements of an event of another vehicle on the display device 4 even if data related to the event is not obtained from the other vehicle.

[0097] Furthermore, when the information processing device 3 according to the modified example estimates data related to an event of another vehicle, the estimated occurrence element of the event of the other vehicle may be displayed on the display device 4 in a manner distinguished from the occurrence element when actually acquired from the drive recorder 2 of the other vehicle. The information processing device 3 according to the modified example may, for example, display the estimated event occurrence element and the actually acquired event occurrence element in different types of display modes.

[0098] Thereby, the information processing device 3 according to the modified example can distinguish between the estimated occurrence element of an event and the actually acquired occurrence element of an event and display them on the display device 4. Therefore, the worker can easily distinguish between the estimated occurrence element of an event and the actually acquired occurrence element of an event.

[0099] Furthermore, the information processing system 1 according to the modified example may identify the occurrence element for the color of the light of a traffic light by the information processing device 3. Specifically, the information processing device 3 according to the modified example executes a predetermined image processing on the image data transmitted from the drive recorder 2 to identify the traffic light, and further identifies the color of the light of the identified traffic light.

[0100] As a result, the information processing system 1 according to the modified example can reduce the processing load on the drive recorder 2.

[0101] Furthermore, the information processing system 1 according to the modified example may include a fixed camera as the data collection device 2. The fixed camera captures a predetermined shooting range. The fixed camera is installed, for example, at a street lamp or on the side of a road. The fixed camera includes, for example, a lens and an imaging element such as a CCD or a CMOS. The fixed camera transmits the location of the fixed camera and the captured image to the information processing device 3 via the communication network N. The information processing device 3 according to the modified example acquires occurrence elements of a vehicle event from the image captured by the fixed camera.

[0102] This allows the information processing device 3 according to the modified example to collect a large amount of information regarding vehicle events, thereby enabling the worker to know the status of the vehicle event more accurately.

[0103] The above-described embodiments and modifications may be applied in combination.

[0104] Further advantages and modifications may readily occur to those skilled in the art. Thus, the invention in its broader aspects is not limited to the specific details and representative embodiments shown and described above. Accordingly, various modifications may be made without departing from the spirit or scope of the general inventive concept as defined by the appended claims and equivalents thereof.
