Description

  The present invention relates to a traffic event information providing system, a central device, an unmanned air vehicle, and a traffic event information providing program, and more particularly to a traffic event information providing system, a central device, the unmanned air vehicle, and a traffic event information providing program using an unmanned air vehicle. About.

  As an example of an intelligent transport system (Intelligent Transport Systems, ITS), there is a road traffic information communication system (Vehicle Information and Communication System, VICS (registered trademark)).

  For example, Non-Patent Document 1 ("Wikipedia", [online], [searched on August 11, 2015], Internet <URL: http: //ja.wikipedia (registered trademark) .org / wiki / road traffic information communication] System>) describes VICS.

  VICS is a system for domestic use that transmits road traffic information collected, processed and edited by the Road Traffic Information Communication System Center via communication / broadcast media, and displays it on a vehicle-mounted device such as a car navigation system as characters or maps. .

  Information provided by VICS includes traffic jam information, travel time information, accident information, broken vehicle information, construction information, speed regulation information, lane regulation information, parking location information, and parking lot, service area or parking area information. Full vehicle information and empty vehicle information. These pieces of information are collected from the prefectural police or road administrator by the Japan Road Traffic Information Center (JARTIC (registered trademark)).

“Wikipedia”, [online], [searched on August 11, 2015], Internet <URL: http: // ja. wikipedia. org / wiki / Road Traffic Information Communication System> “Technology Research and Development Results Report No. 22-1 Contributing to Improvement of Road Policy Quality”, [online], [searched on September 13, 2015], Internet <URL: http: // www. mlit. go. jp / load / tech / jigo / h22 / pdf / report22-1. pdf> “Emergency Call System (HELP)”, [online], [searched on September 13, 2015], Internet <URL: http: // www. utms. or. jp / japanes / system / help. html> “News from Nara National Highway ITS”, [online], [searched on September 13, 2015], Internet <URL: https: // www. kkr. mlit. go. jp / nara / its / 03 / naraITS3-1. htm>

  For example, when a traffic accident occurs, the prefectural police that have received the report dispatch a police officer to the accident site. The police officer dispatched to the accident site confirms the situation of the accident and reports the confirmed content to the prefectural police.

  Here, when an accident occurs on a road with a large amount of traffic, a vehicle involved in the accident may block the road, resulting in traffic congestion on the road. In this case, since the arrival of the police officer at the accident site is delayed due to the generated traffic jam, the report to the prefectural police of the confirmation content by the police officer is also delayed.

  If such a situation occurs, the provision of information from the prefectural police to the VICS will be delayed, and the driver who is heading to the accident site cannot immediately receive the accident information from the VICS. The traffic jam gets worse.

  The optical beacon 131 is, for example, a roadside device installed near the road Rd, and receives road traffic information from the central device 101. Then, the optical beacon 131 transmits the received road traffic information to the road Rd using, for example, infrared rays. The vehicle 11 traveling on the road Rd receives road traffic information from the optical beacon 131 when passing through the vicinity of the optical beacon 131.

  The optical beacon 131 also functions as a vehicle detector, for example, and transmits the detection result of the vehicle 11 traveling on the road Rd to the central device 101.

  The radio beacon 132 is, for example, a roadside device installed in the vicinity of the road Rd, and receives road traffic information from the central device 101. The radio beacon 132 transmits the received road traffic information to the road Rd using, for example, a radio wave of 5.8 GHz band or 2.4 GHz band. The vehicle 11 traveling on the road Rd receives road traffic information from the radio beacon 132 when passing near the radio beacon 132.

  The ITS spot 133 is, for example, a roadside device installed near the road Rd, and receives road traffic information from the central device 101. Then, the ITS spot 133 transmits the received road traffic information to the road Rd using, for example, a radio wave of 5.8 GHz band. The vehicle 11 traveling on the road Rd receives road traffic information from the ITS spot 133 when passing through the vicinity of the ITS spot 133.

  The traffic information board 134 is, for example, a roadside device installed in the vicinity of the road Rd and includes an electric bulletin board.

The vehicle 11 traveling on the road Rd receives road traffic information from the ITS radio 135 when passing through the vicinity of the ITS radio 135.

  The broadcast station 141 can perform FM multiplex broadcasting, for example, and receives road traffic information from the central apparatus 101. For example, the broadcasting station 141 broadcasts road traffic information received from the central device 101 to a predetermined area A1 including a part of the road Rd. When the vehicle 11 traveling on the road Rd passes through a predetermined area A1 formed by the broadcast station 141, the vehicle 11 receives road traffic information from the broadcast station 141.

  In the vehicle 11 traveling on the road Rd, for example, an in-vehicle device (not shown) displays an image including the contents of road traffic information received from the optical beacon 131, the radio beacon 132, the ITS spot 133, the ITS radio 135, or the broadcast station 141. To do. A person who gets on the vehicle 11 can recognize the traffic situation of the road Rd from the image displayed on the in-vehicle device or the content displayed on the electric bulletin board of the traffic information board 134.

  The base station 161 is a base station that is managed and operated by a communication carrier, for example. The base station 161 transmits and receives information to and from the central apparatus 101 by communicating with the central apparatus 101 via the Internet 10, for example.

  The unmanned air vehicle 151 is, for example, a multicopter equipped with a camera as a photographing unit. The unmanned air vehicle 151 transmits and receives information to and from the base station 161 by performing wireless communication with the base station 161 in accordance with, for example, a communication standard of LTE (Long Term Evolution).

  The unmanned air vehicle 151 transmits and receives information to and from the central apparatus 101 via the base station 161 and the Internet 10, for example. For example, the unmanned air vehicle 151 stands by at the base when not in operation. For example, when the unmanned air vehicle 151 receives a flight command to the event occurrence point from the central device 101, the unmanned air vehicle 151 can autonomously fly from the base to the event occurrence point.

  Here, the event is, for example, a traffic accident, a traffic jam, a fallen object, or an escape, stop, or low speed travel of the vehicle 11 on the road Rd.

  In addition, the unmanned air vehicle 151 can receive control information for controlling flight from the central device 101 and perform flight according to the content of the received control information. Here, the control information is information for adjusting, for example, the posture, speed, and moving direction.

[Configuration and basic operation of central unit and unmanned air vehicle]
FIG. 2 is a diagram showing the configuration of the central device in the traffic event information providing system according to the first embodiment of the present invention.

  Referring to FIG. 2, central apparatus 101 includes position information acquisition unit 21, processing unit 22, communication unit (acquisition unit) 23, operation reception unit 24, display unit 25, and provision unit 26. .

  The display unit 25 is a display, for example, and displays an image according to control by the processing unit 22.

  The communication unit 23 transmits and receives information by communicating with the unmanned air vehicle 151 via the Internet 10 and the base station 161, for example.

  The operation reception unit 24 has a function of receiving an input operation by a staff member at a traffic control center, for example.

  The position information acquisition unit 21 acquires position information indicating the position where the event has occurred, for example. More specifically, for example, when receiving a report that an event has occurred from the reporter, the staff member recognizes the coordinates of the position where the event has occurred based on the content of the received report. Here, the coordinates are determined by, for example, latitude and longitude.

  In addition, for example, if the staff can use the reporter's coordinates acquired by the GPS (Global Positioning System) function in a wireless terminal device such as a smart phone used by the reporter, The transmitted coordinates are recognized as the generation position.

  For example, the staff performs an operation on the operation reception unit 24 to input the coordinates of the recognized occurrence position.

  For example, when receiving an operation of a staff member, the operation reception unit 24 outputs the received operation content to the position information acquisition unit 21.

  For example, the position information acquisition unit 21 acquires position information indicating the coordinates of the place of occurrence based on the operation content received from the operation reception unit 24, and outputs the acquired position information to the processing unit 22.

  In addition, for example, the position information acquisition unit 21 receives the detection result of the vehicle 11 by the optical beacon 131 from the optical beacon 131, and acquires the position information by obtaining the coordinates where the event has occurred based on the received detection result. To do.

  At this time, for example, the location information acquisition unit 21 may include Non-Patent Document 2 ("Technology Research and Development Result Report No. 22-1 Contributing to Improvement of Road Policy Quality", [online], [September 13, 2015]. Day search], Internet <URL: http://www.mlit.go.jp/load/tech/jigo/h22/pdf/report22-1.pdf>) Detect the occurrence of an event.

  The position information acquisition unit 21 is not limited to receiving the detection result of the vehicle 11 from the optical beacon 131, but detects the vehicle 11 from another vehicle sensor such as an ultrasonic vehicle sensor or a loop vehicle sensor. Results may be received.

  The location information acquisition unit 21 is, for example, Non-Patent Document 3 ("Emergency Call System (HELP)", [online], [searched on September 13, 2015], Internet <URL: http: // www. utms.or.jp/japan/system/help.html>), the location information may be acquired from an emergency call system operator operating an emergency call system (HELP).

  For example, when receiving the position information from the position information acquisition unit 21, the processing unit 22 transmits the received position information and a flight command to the coordinates indicated by the position information to the unmanned air vehicle 151 via the communication unit 23.

  The staff does not perform an operation for inputting the coordinates of the generation position on the operation reception unit 24, but is a terminal device such as a personal computer, a tablet computer, or a smart phone provided at the base of the unmanned air vehicle 151. The position information and the flight command may be transmitted to the unmanned air vehicle 151 via a LAN (Local Area Network) or directly by wired communication or wireless communication. Further, the staff member may transmit the position information and the flight command to the unmanned air vehicle 151 by using a recording medium such as a flash memory, an optical disk, or a magnetic disk.

  FIG. 3 is a diagram showing a configuration of the unmanned air vehicle in the traffic event information providing system according to the first embodiment of the present invention.

  With reference to FIG. 3, the unmanned air vehicle 151 includes a communication unit (acquisition unit) 41, a processing unit 42, a flight control unit 43, and an imaging unit 44.

  The communication unit 41 acquires the position information of the event occurrence point. Specifically, the communication unit 41 can transmit and receive information by performing wireless communication or wired communication, for example. In this example, the communication unit 41 transmits and receives information to and from the central apparatus 101 via the base station 161 and the Internet 10 by performing wireless communication with the base station 161, for example.

  For example, when the communication unit 41 receives position information and a flight command from the central apparatus 101 via the Internet 10 and the base station 161, the communication unit 41 outputs the received position information and flight command to the processing unit 42.

  Note that the communication unit 41 is not limited to a configuration that receives position information and a flight command from the central apparatus 101 by wireless communication, but as described above, a terminal provided at the base of the unmanned air vehicle 151 by wired communication or wireless communication. The position information and the flight command may be received from the apparatus, or the position information and the flight command may be received from a recording medium on which the position information and the flight command are recorded.

  When the processing unit 42 receives the position information and the flight command from the communication unit 41, the processing unit 42 outputs a control command for autonomously flying the unmanned air vehicle 151 to the coordinates indicated by the received position information to the flight control unit 43.

  The flight control unit 43 performs control for flying to the event occurrence point based on the position information acquired by the communication unit 41.

  Specifically, for example, when the flight control unit 43 receives a control command from the processing unit 42, the flight control unit 43 controls each rotor of the unmanned flight vehicle 151 according to the received control command to control the unmanned flight vehicle 151. The autonomous flight is made to the coordinates indicated by the position information.

  For example, when the flight control unit 43 reaches above the event occurrence point, the flight control unit 43 notifies the processing unit 42 that the event occurrence point has been reached and sets an imaging area including the occurrence point.

  For example, the flight control unit 43 performs control such as turning in the sky while changing the altitude or changing the posture so that the shooting direction of the camera faces the shooting area in the sky above the set shooting area. This is performed on the body 151.

  For example, when the processing unit 42 receives a notification from the flight control unit 43 that the unmanned air vehicle 151 has reached the event occurrence point, the processing unit 42 outputs a shooting command to the shooting unit 44.

  The imaging unit 44 captures an image of an imaging area including an event occurrence point. Specifically, for example, when receiving a shooting command from the processing unit 42, the shooting unit 44 takes a picture of the shooting area in accordance with the received shooting command.

  The photographing unit 44 creates image information including, for example, the photographed image, the photographing time, the coordinates indicating the position where the photographing was performed, the photographing direction, the focal length at the time of photographing, and the like, and outputs the image information to the processing unit 42.

  When receiving the image information from the photographing unit 44, the processing unit 42 outputs the received image information to the communication unit 41.

  When receiving the image information from the processing unit 42, the communication unit 41 transmits the received image information to the central apparatus 101 via the base station 161 and the Internet 10.

  Referring to FIG. 2 again, the communication unit 23 in the central apparatus 101 acquires an image photographed by the unmanned air vehicle 151. Specifically, for example, when receiving image information from the unmanned aerial vehicle 151, the communication unit 23 outputs the received image information to the processing unit 22.

  For example, when the processing unit 22 receives image information from the communication unit 23, the processing unit 22 performs control to display the content of the received image information on the display unit 25.

  For example, the staff makes a determination regarding the event based on the content displayed on the display unit 25. Here, the determination regarding the event is, for example, whether or not the event has occurred.

  At this time, the staff can finely adjust the position and posture of the unmanned air vehicle 151 based on the content displayed on the display unit 25, for example. More specifically, the staff member performs an operation on the operation reception unit 24 for fine adjustment of the position and posture of the unmanned air vehicle 151, for example. For example, when the operation reception unit 24 receives an operation by a staff member, the operation reception unit 24 outputs the received operation content to the processing unit 22. For example, the processing unit 22 creates control information corresponding to the operation content received from the operation accepting unit 24, and transmits the created control information to the unmanned air vehicle 151 via the communication unit 23.

  For example, when it is determined that an event has occurred, the staff performs an operation on the operation reception unit 24 to input the determination result, the type of the event, and the content of the event.

  Here, when the type of the event is a traffic accident, the content of the event is, for example, the position where the traffic accident occurred, the scale of the traffic accident, and the like.

  When the type of event is traffic jam, the content of the event is, for example, the length of the traffic jam, the head position of the traffic jam, and the like.

  When the type of event is a falling object, the event content is, for example, the size of the falling object, the type of the falling object, and the position of the falling object.

  When the event type is avoidance, stop, or low speed travel of the vehicle 11 on the road Rd, the event content includes, for example, the causal object that causes the vehicle 11 to escape, stop, or low speed travel, and the cause The position of the object.

  For example, when receiving an operation by a staff member, the operation receiving unit 24 outputs the received operation content to the providing unit 26.

  The providing unit 26 provides event information related to an event based on the determination result related to the event using the image acquired by the communication unit 23.

  Specifically, for example, when the determination result indicates the occurrence of an event in the operation content received from the operation reception unit 24, the providing unit 26 includes the type of the event and the content of the event based on the operation content. Create traffic event information.

  For example, the providing unit 26 acquires an image included in the image information from the communication unit 23 from the processing unit 22, and further includes the acquired image in the traffic event information.

  The providing unit 26 transmits the created traffic event information to, for example, the optical beacon 131, the radio beacon 132, the ITS spot 133, the traffic information board 134, the ITS radio 135, and the broadcasting station 141, and provides the traffic event information. The processing unit 22 is notified of the completion.

  For example, when the optical beacon 131, the radio beacon 132, the ITS spot 133, and the ITS wireless device 135 receive the traffic event information from the central apparatus 101, the received traffic event information is transmitted to the road Rd.

  For example, when traffic information board 134 receives traffic event information from central apparatus 101, traffic information board 134 displays the contents of the received traffic event information on an electronic bulletin board.

  For example, when the broadcast station 141 receives traffic event information from the central device 101, the broadcast station 141 transmits a broadcast wave including the received traffic event information to the predetermined area A1.

  The providing unit 26 may transmit the traffic event information to a wireless terminal device such as a smart phone carried by a person who rides on the vehicle 11.

  On the other hand, the staff member performs an operation for returning the unmanned air vehicle 151 to the operation reception unit 24 when, for example, it is determined that no event has occurred or when it has been determined that the occurred event has been resolved.

  For example, when the operation reception unit 24 receives an operation by a staff member, the operation reception unit 24 outputs the received operation content to the processing unit 22.

  When the processing unit 22 receives a notification that the provision of the traffic event information is completed from the providing unit 26 or receives the operation content for returning the unmanned air vehicle 151 from the operation receiving unit 24, the processing unit 22 returns to the base. Is transmitted to the unmanned air vehicle 151 via the communication unit 23.

  In addition, since the content displayed on the display unit 25 is insufficient, it is difficult for a staff member to make an event-related determination from the content, and an operation for enlarging the shooting area is performed on the operation reception unit 24. Do it.

  For example, when the operation reception unit 24 receives an operation by a staff member, the operation reception unit 24 outputs the received operation content to the processing unit 22.

  For example, the processing unit 22 creates an area enlargement command for enlarging the imaging area based on the operation content received from the operation accepting unit 24, and transmits the created area enlargement command to the unmanned air vehicle 151 via the communication unit 23. To do.

  Referring to FIG. 3 again, for example, when communication unit 41 in unmanned air vehicle 151 receives a feedback command from central apparatus 101 via Internet 10 and base station 161, it outputs the received feedback command to processing unit 42.

  When the processing unit 42 receives the return command from the communication unit 41, the processing unit 42 outputs a control command for autonomously flying its own unmanned air vehicle 151 to the base to the flight control unit 43.

  For example, when the flight control unit 43 receives a control command from the processing unit 42, the flight control unit 43 autonomously flies the unmanned flight vehicle 151 to the base by controlling each rotor of the unmanned flight vehicle 151 according to the received control command. .

  For example, when the communication unit 41 receives an area expansion command from the central apparatus 101 via the Internet 10 and the base station 161, the communication unit 41 outputs the received area expansion command to the processing unit 42.

  When the processing unit 42 receives an area expansion command from the communication unit 41, the processing unit 42 outputs the received area expansion command to the flight control unit 43 and outputs a shooting command to the imaging unit 44.

  When the flight control unit 43 receives an area expansion command from the processing unit 42, the flight control unit 43 expands the shooting area according to the received area expansion command. Then, the flight control unit 43 performs control to turn while changing the altitude or changing the posture so that the shooting direction of the camera faces the enlarged shooting area in the sky above the enlarged shooting area. This is performed on the flying object 151.

[Operation]
Each device in the traffic event information providing system includes a computer, and an arithmetic processing unit such as a CPU in the computer reads a program including a part or all of each step of the following sequence diagram or flowchart from a memory (not shown). Run. Each of the programs of the plurality of apparatuses can be installed from the outside. The programs of the plurality of apparatuses are distributed while being stored in a recording medium.

  FIG. 4 is a diagram illustrating an example of a sequence when traffic event information provision processing is performed in the traffic event information provision system according to the first embodiment of the present invention.

  First, for example, when an event occurs on the road Rd, the central apparatus 101 acquires position information indicating the occurrence point of the event (step S102).

  Next, the central apparatus 101 transmits the acquired position information and flight command to the unmanned air vehicle 151 via the Internet 10 and the base station 161 (step S104).

  Next, when the unmanned aerial vehicle 151 receives the position information and the flight command from the central device 101, it autonomously flies to the coordinates indicated by the received position information (step S106).

  Next, when the unmanned aerial vehicle 151 reaches above the event occurrence point, the unmanned air vehicle 151 changes the altitude or changes the inclination of the aircraft so that the shooting direction of the camera faces the shooting area above the occurrence point. While turning (step S108).

  Next, the unmanned air vehicle 151 captures an image of the imaging area and creates image information based on the captured image. The unmanned air vehicle 151 transmits the created image information to the central apparatus 101 via the base station 161 and the Internet 10 (step S110).

  Next, when the central apparatus 101 receives image information from the unmanned air vehicle 151, the central apparatus 101 displays the content of the received image information (step S112).

  Next, the central apparatus 101 receives an operation by a staff member who has made a determination regarding the event (step S114).

  Next, when the received operation content indicates the occurrence of an event (YES in step S116), the central apparatus 101 creates traffic event information including the type of the event and the content of the event based on the operation content. Providing the created traffic event information. Specifically, the central apparatus 101 transmits traffic event information to the optical beacon 131, the radio beacon 132, the ITS spot 133, the traffic information board 134, the ITS radio 135, and the broadcast station 141 (step S118).

  Next, the central apparatus 101 transmits a return instruction to the unmanned air vehicle 151 via the Internet 10 and the base station 161 (step S120).

  On the other hand, if the received operation content indicates that the unmanned air vehicle 151 should be returned and does not indicate the occurrence of an event (NO in step S116), the central device 101 issues a return command via the Internet 10 and the base station 161. It transmits to the unmanned air vehicle 151 (step S120).

  Next, when the unmanned air vehicle 151 receives the return command from the central device 101, it autonomously flies to the base in accordance with the received feedback command (step S122).

  Note that the central device 101 is not limited to the configuration for obtaining the determination regarding the event by the visual observation of the staff in step S114, and may perform the determination regarding the event by performing image processing on the image received from the unmanned air vehicle 151. . At this time, the central apparatus 101 is, for example, Non-Patent Document 3 (“News from Nara National Highway ITS”, [online], [searched on September 13, 2015], Internet <URL: https: //www.kkr. mlit.go.jp/nar/its/03/naraITS3-1.htm>).

  Further, when the unmanned air vehicle 151 receives the feedback command from the central device 101 in step S120, the unmanned air vehicle 151 flies autonomously to the base according to the received feedback command (step S122), but returns to the base based on its own judgment. May be. Specifically, the unmanned aerial vehicle 151 may determine whether or not to return to the base based on, for example, the remaining battery level.

  The unmanned air vehicle 151 is configured to autonomously fly to the event occurrence point, but is not limited thereto. For example, the control information for the central device 101 to fly to the event occurrence point is transmitted to the unmanned air vehicle 151, and the unmanned air vehicle 151 flies to the event occurrence point according to the content of the control information received from the central device 101. It may be a configuration.

  By the way, for example, when a traffic accident occurs, the prefectural police who have received the report dispatch a police officer to the accident site. The police officer dispatched to the accident site confirms the situation of the accident and reports the confirmed content to the prefectural police.

  Here, when an accident occurs on a road with a large amount of traffic, a vehicle involved in the accident may block the road, resulting in traffic congestion on the road. In this case, since the arrival of the police officer at the accident site is delayed due to the generated traffic jam, the report to the prefectural police of the confirmation content by the police officer is also delayed.

  If such a situation occurs, the provision of information from the prefectural police to the VICS will be delayed, and the driver who is heading to the accident site cannot immediately receive the accident information from the VICS. The traffic jam gets worse.

  On the other hand, in the traffic event information providing system according to the first embodiment of the present invention, the unmanned air vehicle 151 acquires the position information of the event occurrence point, and moves to the occurrence point based on the acquired position information. Fly and take an image of the shooting area including the point of occurrence. Then, the providing unit 26 provides event information related to the event based on the determination result related to the event using the image captured by the unmanned air vehicle 151.

  With such a configuration, for example, even when a road where an event occurs is congested, the unmanned air vehicle 151 that can fly linearly over the sky without traffic jam can quickly reach the event occurrence point. As a result, the image of the shooting area can be quickly acquired. As a result, event information can be promptly provided to VICS, for example, so that drivers who are heading to the accident site can quickly receive accident information from VICS and avoid traffic congestion such as route changes. You can move on to action. Therefore, information regarding the event can be provided more quickly.

  In the traffic event information providing system according to the first embodiment of the present invention, the central apparatus 101 acquires an image photographed by the unmanned air vehicle 151. And the central apparatus 101 provides event information based on the result of the determination performed using the acquired image as a providing unit.

  With such a configuration, in the determination regarding the event using the image, for example, a determination by a human can be taken into consideration, so that a more appropriate determination can be made. Thereby, more appropriate event information can be provided.

  In the central device according to the first embodiment of the present invention, the communication unit 23 acquires the position information of the event occurrence point, flies to the occurrence point based on the acquired position information, and includes the occurrence point An image taken by the unmanned air vehicle 151 for taking an image of the shooting area is acquired. Then, the providing unit 26 provides event information related to the event based on the determination result related to the event using the image acquired by the communication unit 23.

  With such a configuration, for example, even when a road on which an event has occurred is congested, the central device 101 can fly linearly over the sky without traffic and can quickly reach the event occurrence point. The image of the shooting area can be quickly acquired from the unmanned flying vehicle 151 that can be used. As a result, event information can be promptly provided to VICS, for example, so that drivers who are heading to the accident site can quickly receive accident information from VICS and avoid traffic congestion such as route changes. You can move on to action. Therefore, information regarding the event can be provided more quickly.

  Next, another embodiment of the present invention will be described with reference to the drawings. In the drawings, the same or corresponding parts are denoted by the same reference numerals and description thereof will not be repeated.

  Referring to FIG. 6, unmanned aerial vehicle 152 further includes a determination unit 45, a providing unit 46, and a broadcasting unit 47, as compared with unmanned aerial vehicle 151 shown in FIG. 3.

  The operations of the communication unit 41, the processing unit 42, the flight control unit 43, and the imaging unit 44 in the unmanned air vehicle 152 are the same as those of the communication unit 41, the processing unit 42, the flight control unit 43, and the imaging unit 44 in the unmanned air vehicle 151 shown in FIG. And the same for each.

  For example, when receiving image information from the imaging unit 44, the processing unit 42 outputs the received image information to the determination unit 45.

  For example, the determination unit 45 performs a determination regarding an event using an image captured by the imaging unit 44.

  Specifically, for example, when receiving the image information from the processing unit 42, the determining unit 45 determines whether there is an event based on the received image.

  More specifically, for example, for the image included in the image information, the determination unit 45 considers the shooting time included in the image information, the coordinates indicating the shooting position, the shooting direction, and the focal length at the time of shooting. Then, image processing is performed, and the presence or absence of an event is determined based on the result of the image processing.

  For example, when determining that an event has occurred, the determination unit 45 calculates the position AP where the event has occurred based on the coordinates, the imaging direction, and the focal distance. At this time, the determination unit 45 calculates, for example, coordinates as the position AP. Note that the determination unit 45 may calculate a position on the road as the position AP by holding a map database and comparing the calculated position AP and the database, for example. Specifically, for example, the determination unit 45 calculates C meters in the B direction from the A intersection.

  For example, the determination unit 45 outputs the calculated position AP and the image information from the processing unit 42 to the providing unit 46 as a result of the image processing.

  On the other hand, the determination unit 45 notifies the processing unit 42 of the determination result when, for example, it is determined that no event has occurred or when it has been determined that the event that has occurred has been resolved.

  Further, for example, when the determination unit 45 determines that it is difficult to make a determination regarding an event from the content because the content of the image information is insufficient, the determination unit 45 processes that the content of the image information is insufficient. Notification to the unit 42.

  For example, when receiving a notification that the content of the image information is insufficient from the determination unit 45, the processing unit 42 outputs an area enlargement command to the flight control unit 43 and outputs a shooting command to the shooting unit 44.

  The providing unit 46 provides event information related to the event based on the result of the determination related to the event using the image captured by the image capturing unit 44.

  Specifically, for example, when receiving the position AP and the image information as a result of the image processing from the determination unit 45, the providing unit 46 determines the type of the event and the type of the event based on the received result of the image processing, the position AP and the image information. Identify the details of the event.

  Then, for example, the providing unit 46 creates traffic event information including the type of the identified event, the content of the event, and an image included in the image information, and the created traffic event information is transmitted to the communication unit 41 and the broadcasting unit 47. Output to.

  For example, when receiving the traffic event information from the providing unit 46, the communication unit 41 transmits the received traffic event information to the central apparatus 102 via the base station 161 and the Internet 10. In addition, the communication unit 41 transmits a wireless signal including an electronic mail having the contents of traffic event information to a wireless terminal device such as a smart phone carried by a person who gets on the vehicle 11 according to the LTE communication standard.

  For example, the broadcast unit 47 transmits a radio signal including the created event information to a device in the vehicle 11.

  Specifically, for example, when receiving the traffic event information from the providing unit 46, the broadcasting unit 47 transmits the received traffic event information to the road Rd using a 760 MHz band radio signal. Moreover, the broadcast part 47 transmits the radio | wireless signal containing traffic event information to the road Rd according to the communication standard of eMBMS (evolved Multimedia Broadcast Service: LTE broadcast), for example.

  For example, when a radio terminal device carried by a person who rides on the vehicle 11 receives a radio signal conforming to the LTE communication standard from the unmanned air vehicle 152, the content of the electronic mail included in the received radio signal, that is, the content of the traffic event information is displayed. Display the image that contains it. The in-vehicle device in the vehicle 11 traveling in the vicinity of the unmanned aerial vehicle 152 receives, for example, a 760 MHz band radio signal or a radio signal conforming to the LTE broadcast communication standard from the unmanned aerial vehicle 152 and is included in the received radio signal. The image including the contents of the traffic event information is displayed. Thereby, the person who gets on the said vehicle 11 can recognize the detail of an event based on at least any one of these images.

  For example, when the processing unit 42 receives a notification from the determination unit 45 that no event has occurred or that the generated event has been resolved, the processing unit 42 flies a control command for autonomously flying its own unmanned air vehicle 152 to the base. Output to the control unit 43.

  FIG. 7 is a diagram showing the configuration of the central device in the traffic event information providing system according to the second embodiment of the present invention.

  With reference to FIG. 7, the central apparatus 102 includes a transmitting unit 27 instead of the providing unit 26 as compared with the central apparatus 101 illustrated in FIG. 2.

  The operations of the position information acquisition unit 21, the processing unit 22, the communication unit 23, the operation reception unit 24, and the display unit 25 in the central apparatus 102 are the same as the position information acquisition unit 21, the processing unit 22, and the communication unit in the central apparatus 101 illustrated in FIG. 23, the same as the operation receiving unit 24 and the display unit 25, respectively.

  When the communication unit 23 in the central apparatus 102 receives the traffic event information from the unmanned air vehicle 152, the communication unit 23 outputs the received traffic event information to the processing unit 22.

  For example, when receiving the traffic event information from the communication unit 23, the processing unit 22 outputs the received traffic event information to the transmission unit 27.

  For example, when the transmission unit 27 receives the traffic event information from the processing unit 22, the transmission unit 27 transmits the received traffic event information to the optical beacon 131, the radio beacon 132, the ITS spot 133, the traffic information board 134, the ITS radio 135, and the broadcasting station 141.

  Next, the unmanned air vehicle 152 broadcasts a radio signal including the created traffic event information to the in-vehicle device in the vehicle 11 (step S220).

  Further, when the central device 102 receives traffic event information from the unmanned air vehicle 152, the central device 102 converts the received traffic event information into an optical beacon 131, a radio beacon 132, an ITS spot 133, a traffic information board 134, an ITS radio 135, and a broadcasting station 141. (Step S222).

  Next, the unmanned air vehicle 152 flies autonomously to the base and returns (step S224).

  If the unmanned air vehicle 152 determines that no event has occurred or that the event has been resolved (NO in step S214), the unmanned air vehicle 152 flies autonomously to the base and returns (step S224).

  Note that the order of steps S218 and S220 is not limited to the above, and the order may be changed.

  As described above, in the traffic event information providing system according to the second embodiment of the present invention, the unmanned air vehicle 152 makes a determination regarding an event using the captured image and creates event information.

  With such a configuration, the unmanned air vehicle 152 can complete the process up to the creation of event information, so that event information can be created efficiently, for example.

  In the traffic event information providing system according to the second embodiment of the present invention, the unmanned air vehicle 152 transmits a radio signal including the created event information to a device in the vehicle 11.

  With such a configuration, for example, the unmanned air vehicle 152 functions as a roadside device or a broadcasting station even in an area where road traffic information such as a roadside device or a broadcasting station that performs FM multiplex broadcasting is not provided. Thus, the vehicle 11 can receive the event information.

  Moreover, in the unmanned air vehicle according to the second embodiment of the present invention, the communication unit 41 acquires the position information of the event occurrence point. The flight control unit 43 performs control for flying to the generation point based on the position information acquired by the communication unit 41. The imaging unit 44 captures an image of the imaging area including the occurrence point. Then, the providing unit 46 provides event information related to the event based on the determination result related to the event using the image captured by the image capturing unit 44.

  With such a configuration, for example, even when a road on which an event has occurred is congested, the unmanned air vehicle 152 that can fly linearly over the sky without traffic congestion can quickly reach the event occurrence point. As a result, the image of the shooting area can be quickly acquired. As a result, event information can be promptly provided to VICS, for example, so that drivers who are heading to the accident site can quickly receive accident information from VICS and avoid traffic congestion such as route changes. You can move on to action. Therefore, information regarding the event can be provided more quickly.

  Since other configurations and operations are the same as those of the traffic event information providing system according to the first embodiment, detailed description thereof will not be repeated here.
