Hereinafter, each component with which the driving assistance information display system 100 is provided is demonstrated.

  The antenna 101 transmits and receives an ITS (Intelligent Transportation Systems) radio signal or a radio signal of a communication system such as a mobile phone. The antenna 103 receives a signal from a GPS (Global Positioning System) satellite.

  As shown in FIG. 2, the front camera 105 is provided approximately at the center of a front grill (radiator grill) of a four-wheeled vehicle (hereinafter referred to as “vehicle”). FIG. 2 is a diagram of a vehicle equipped with the driving support information display system 100 shown in FIG. The front camera 105 has a wide-angle lens and photographs the front of the vehicle at a wide angle. In particular, the front camera 105 captures a scene in front of the vehicle (a blind spot area in front of the vehicle) that is hidden behind the vehicle hood when the driver is sitting in the driver's seat and facing the front. A signal indicating an image captured by the front camera 105 is input to the driving support device 109.

  On the display 107, an image captured by the front camera 105 is displayed in real time. The display 107 also displays the result of image analysis performed by the driving support device 109 on the video captured by the front camera 105, and the like. FIG. 3 is a diagram illustrating an example of a state inside the vehicle when facing the front window side inside the vehicle on which the driving support information display system 100 illustrated in FIG. 1 is mounted. FIG. 4 is a diagram schematically showing a cross section taken along line AA of FIG. As shown in FIG. 3, the display 107 is provided in a state where it is incorporated in a dashboard 155 below a front window 153 on the driver's seat 151 side of the vehicle. Note that the dashboard 155 on the driver's seat 151 side protrudes toward the driver side at an angle that hardly obstructs the driver's field of view as shown in FIG. 4 when the driver sits in the driver's seat and faces the front.

  As shown in FIG. 3, the display 107 displays a scenery on the driver's seat 151 side taken by the front camera 105 below the front window 153 when viewed from the driver. In the example illustrated in FIG. 3, the scenery displayed on the display 107 is displayed without any overlap with the scenery through the front window 153. That is, the image displayed on the display 107 is visually continuous with the lower end of the scenery on the driver seat 151 side seen through the front window 153 in a state where the driver is sitting on the driver seat 151 of the vehicle and facing the front. The lower end of the scenery on the driver's seat 151 side seen through the front window 153 and the image displayed on the display 107 do not necessarily have to be continuous, but the display 107 displays an image including a blind spot area in front of the vehicle. Yes.

  In addition, as shown in FIG. 3, as a result of the driving support device 109 analyzing the image captured by the front camera 105, the display 107 displays the image of the driver on an object relatively approaching the traveling area of the vehicle. Highlights 201, 203, 205 for directing attention and information on each object are displayed superimposed on the scenery photographed by the front camera 105. In addition, the pedestrian, a vehicle, a traffic light, etc. are contained in the target object which a driver should be careful of. Moreover, the information regarding a target object is the mark etc. which show the state of a traffic light, the running speed of a vehicle, and the presence of a pedestrian or a vehicle. Note that the driving support device 109 may determine the pedestrian or vehicle as an object highlighted on the display 107 based on the ITS radio signal received by the antenna 101.

  Further, when the driving support device 109 performs navigation, the navigation information is also displayed on the display 107. Further, a message based on a signal received by the antenna 101 is displayed on the display 107. The message based on the signal received by the antenna 101 is, for example, a mark such as an icon or a jacket used by another electronic device connected by wire or wireless (including public wireless), and the other electronic device receives the message. A notification corresponding to an operation performed on the other electronic device, a notification set in advance for a processing result of the driving support device 109, or the like.

  The driving support device 109 performs processing for displaying the video captured by the front camera 105 on the display 107, analysis processing based on the video, and processing corresponding to the radio signals received by the antennas 101 and 103. The driving support device 109 includes a display processing unit 111, an analysis unit 113, a navigation processing unit 115, a wireless unit 117, and a control unit 119.

  The display processing unit 111 performs processing so that at least a part of the video captured by the front camera 105 is displayed on the display 107. Further, the display processing unit 111 captures information based on the result of analysis by the analysis unit 113 sent from the control unit 119, the result of processing by the navigation processing unit 115, or the signal received by the wireless unit 117, by the front camera 105. It is processed so as to be displayed on the display 107 so as to be superimposed on the video.

  The analysis unit 113 analyzes the image captured by the front camera 105, and if an object that should be noted by the driver, such as a pedestrian, a vehicle, or a traffic light, is included in the image, its type, position, and size. Alternatively, the state or the like is determined. For example, in the case of the example illustrated in FIG. 3, the analysis unit 113 recognizes the presence of a pedestrian, a vehicle, and a traffic light, and detects the position and size of the pedestrian, the position of the vehicle, the size and the traveling speed, and the traffic light. Determine position, size and condition. The analysis unit 113 sends information on highlighting according to the determination result and information on each object to the control unit 119.

  The navigation processing unit 115 performs processing related to navigation according to the signal received by the antenna 103. Information obtained by the processing performed by the navigation processing unit 115 is sent to the control unit 119. The radio unit 117 generates a transmission signal by decoding a signal received by the antenna 101 or encoding and modulating transmission data. The data decoded by the wireless unit 117 is sent to the control unit 119.

  The control unit 119 appropriately processes the information related to the analysis result of the analysis unit 113, the information related to the processing result of the navigation processing unit 115, or the data sent from the wireless unit 117, and displays it as driving support information. To 111.

  As described above, in the driving support information display system 100 according to the present embodiment, the driver sits directly on the driver's seat 151 of the vehicle and faces the front, and immediately below the lower end of the scenery on the driver's seat side seen through the front window 153. The display 107 is installed in the dashboard 155 so that the display surface of the display 107 can be seen. Therefore, the driver who is driving the vehicle can check the information displayed on the display 107 with a small viewpoint movement.

  In addition, you may change the image | video which the front camera 105 displayed on the display 107 image | photographed according to the travel speed (vehicle speed) of a vehicle. When driving at a low vehicle speed, the driver tends to look wide on the front side, and as the vehicle speed increases, the driver's viewpoint becomes farther and the viewing angle becomes smaller. For this reason, by using a desired area of the video imaged by the front camera 105, an image that matches the viewpoint of the driver and the tendency of the viewing angle can be displayed on the display 107.

  Further, as described above, the driving support information is displayed on the display 107 so as to overlap the video captured by the front camera 105 that captures the front of the vehicle at a wide angle. Therefore, the driver can confirm information that is helpful for safe driving, information on the travel route, or other messages together with the actual front image. Furthermore, since the front camera 105 captures the blind spot area in front of the vehicle, the driver can check the blind spot area on the display 107 together with the scenery seen through the front window 153.

  For example, when the driver displays a roadside curb or a U-shaped groove or the like when the image displayed on the display 107 at the time of a left turn, the driver superimposes a virtual image of the left front wheel by computer graphic processing on the image of the front camera 105. If displayed on 107, it is possible to avoid dangers such as contact or rear-end collision with the road stone or wheeled off in the U-shaped groove. Further, when passing through a narrow road or a shopping street, if a virtual image showing the vehicle width by computer graphic processing is displayed on the display 107 superimposed on the image of the front camera 105, a power pole or obstacle on the left roadside, or a pedestrian, It is possible to easily check whether a vehicle can pass while avoiding a bicycle or a dog while taking a walk, or whether it is not in contact with an oncoming vehicle.

  In addition, since the visual function of a person deteriorates at dusk and at night, the time required to recognize an obstacle becomes longer than in the daytime. This is because the edge between the obstacle and the surrounding scenery is not clear after twilight. However, if the front camera 105 has a photographing function using infrared rays or the edge discrimination function of the analysis unit 113 of the driving support device 109 is high, the obstacle can be highlighted and displayed on the display 107. Therefore, contact with an obstacle or rear-end collision can be avoided even at dusk or at night.

  In addition, the driving support device 109 recognizes a pedestrian or vehicle based on the ITS radio signal received by the antenna 101, and then highlights the object on the display 107, so that the vehicle or driver from the building shadow can Collisions with bicycles that are often overlooked can be avoided. In addition, by displaying information such as the travel route on the image captured by the front camera 105, the driver can drive toward the destination without looking at the map.

  Further, when the rear camera is included in the driving support information display system and the video signal captured by the rear camera is input to the display processing unit 111 of the driving support device 109 as in the case of the front camera 105, the driving support information display system approaches from the rear of the vehicle. Since the vehicle or the like coming is displayed on the display 107, the driver can confirm this with a small viewpoint movement.

  When entering a tunnel while driving outdoors in the daytime, it is very difficult for the driver to recognize an obstacle for several seconds until the driver adapts to darkness. That is, it takes several seconds for a person to visually distinguish an obstacle when moving from a bright place to a dark place suddenly. During this period, that is, while the driver's eyes are dark adapting, the information displayed on the display 107 is valid.

  In the present embodiment, as shown in FIG. 2, one front camera 105 is provided, but a plurality of front cameras 105 may be provided.

  The driving support information display system according to the present invention is useful as a system or the like in which a driver who is driving a vehicle can confirm information displayed on a display with a small viewpoint movement.
