Description

  The present invention relates to an information display system that is mounted on an automobile and displays various types of information.

  In-vehicle display devices that are connected to information generation devices such as television receivers, VICS receivers, navigation systems, and the like and that output information from these information generation devices is displayed on their display screens as automobiles become more sophisticated Has appeared. Display content determination means for determining whether information displayed on a display screen capable of changing the display direction is video information such as television broadcast or driving support information such as travel route guidance in one of such in-vehicle display devices There is something with. This in-vehicle display device displays the video information from the driver's seat and the passenger seat so as to be visible when a stop of the vehicle is detected, and is displayed based on the display content determination means when the vehicle's travel is detected. When the information to be displayed is video information, the video information from the driver's seat is prevented from being visually recognized, and the video information is displayed from the front passenger seat so that it can be viewed. It displays so that visual recognition is possible (for example, refer patent document 1). As a result, if the information displayed on the display screen is navigation information or VICS information necessary for driving, the direction of the display screen is automatically moved to the driver's seat side, or if it is a video such as a TV reception screen, it is automatically moved to the passenger seat side. Thus, appropriate information display according to the passengers in the car is realized.

  There is also known an in-vehicle information providing apparatus that more appropriately provides information according to a traveling environment in which the vehicle changes. For example, information such as TV images and contents is provided only when the parking brake is operating. Thus, even when the vehicle is traveling, appropriate information for the passenger is provided according to the traveling environment that changes.

  Furthermore, a suspicious person monitoring device comprising a sensor for detecting an abnormality of the vehicle, a camera for taking an image, and means for outputting the camera image taken by the camera to an in-vehicle display device for car navigation mounted on the vehicle is also provided. It is known (see, for example, Patent Document 3). The suspicious person monitoring device of Patent Document 3 is configured to display a camera image on an in-vehicle display device when a sensor that detects an abnormality of the vehicle detects the abnormality. However, since this in-vehicle display device is disposed at the position of a normal car navigation panel, it is not easy for a suspicious person to visually recognize from the outside of the vehicle.

JP 2006-36192 A (paragraph numbers 0005, 0025-0034, FIG. 4) JP 2005-24494 A (paragraph numbers 0030-0036, abstract) Japanese Patent Laying-Open No. 2005-280401 (paragraph number 0011, abstract)

In the above-described conventional information display system for automobiles, it is possible to display appropriate information at the time of traveling or stopping for an occupant sitting in a driver seat or a passenger seat, but the occupant goes out of the vehicle. During parking when there were no people in the car, the provision of information through the information display system was not considered as meaningless. However, even in such a parked automobile, there are not a few situations in which some information needs to be displayed outside the vehicle to attract attention and interest from people around the vehicle. Examples of information that should be emitted from a parked car include threats against fraudulent acts on a parked unmanned car, the time when the driver returns, and the reason for parking.
In view of such a situation, an object of the present invention is to provide an automobile information display system capable of displaying appropriate information during parking.

  In order to solve the above-mentioned problems, a first characteristic configuration of an automobile information display system according to the present invention includes a parking time information generation unit that generates parking time information to be displayed in a parking state, and a traveling time that the vehicle displays in a traveling state. A travel time information generating unit for generating information; and display means for displaying the parking time information and the travel time information, wherein the display means has a display panel, and the display panel is in a first orientation facing in the vehicle. Between the vehicle and the vehicle-facing second posture, the parking time information is displayed in the second posture, and the driving information is displayed in the first posture. With this feature configuration, while using a common display panel, parking time information can be displayed to a person located outside the vehicle in the first posture of the display panel, and the vehicle interior can be displayed in the second posture of the display panel. Information can be shown to other passengers.

  The most worrying thing about parking when leaving an unattended car is theft or hurt. For this reason, as a second feature configuration, when a suspicious person detection unit that detects a suspicious person outside the parked vehicle and outputs suspicious person detection information is mounted on the vehicle, the suspicious person detection information It is advantageous if the parking time information generation unit generates suspicious intimidation information as the parking time information and causes the display means to display the information on the display means.

  Parking an unmanned vehicle in a place that is not a regular parking place is annoying to others, but it can often be understood when it takes only a short time or when the purpose is handling luggage or a suddenly ill person. For this reason, as a third characteristic configuration, it is also convenient to configure such that parking-related information such as the parking start time, return scheduled time, parking purpose, etc. of the vehicle is displayed on the display means as the parking time information. . Further, as a fourth characteristic configuration, when the vehicle is parked at a regular parking place, if a predetermined advertisement can be displayed as parking information, the possibility of new commercial activities can be opened.

  One preferred method for detecting the parking state where the driver leaves the vehicle is to detect a door lock operation performed from the outside. For this reason, as a fifth characteristic configuration, a function for enabling the display means to display the parking time information on the display means based on a door lock operation performed from the outside is introduced. It can be smoothly introduced into the system.

  Of course, as a sixth characteristic configuration, it is important that the information display system for automobiles according to the present invention can be used effectively other than during parking. For this purpose, the display means may be configured to display traveling time information in the traveling state of the vehicle.

  As a seventh characteristic configuration, the display means may be configured to be attached to a door panel. If it is this structure, it becomes easy to visually recognize the parking time information from the outside of the vehicle. For example, when the parking time information is suspicious person threatening information, the threatening effect can be increased.

It is also possible to display the suspicious person himself / herself on the monitor 7a. Furthermore, although not shown, it is also possible to display information, advertisements, etc. arbitrarily set by the user, such as for parking purposes. Displaying such advertisements may develop new commercial activities.

  Next, the suspicious person detection unit 8 will be described. FIG. 7 is a block diagram schematically showing the configuration of the suspicious person detection unit 8 provided in the automobile information display system. The suspicious person detection unit 8 includes a photographing unit 11 and a sensor unit 12 and detects a suspicious person. The sensor unit 12 includes obstacle sensors 31 to 35 such as an infrared sensor, and outputs a signal in response to detection of an object approaching the automobile. Based on this output signal, the object approach determination unit 13 determines whether an object is approaching the automobile. If the object is approaching, the imaging control unit 14 activates the imaging unit 11 and outputs a control signal for starting imaging to the imaging unit 11. The photographing means 11 starts photographing based on this control signal. The photographing means 11 is composed of a monitoring camera 30 composed of a photographing lens, a photoelectric conversion element, and the like. The photographing means 11 performs photographing around the automobile and converts it into image data handled by the suspicious person detection unit. However, in the present invention, unless specifically distinguished, the photographed image and image data obtained by photographing are collectively referred to as “captured image”.

  FIG. 8 is a diagram illustrating an outline of the arrangement of the monitoring camera 30 and the obstacle sensors 31 to 35, and FIG. 9 is a diagram illustrating a monitoring area of the obstacle sensors 31 to 35. As shown in FIG. 8, the surveillance camera 30 is disposed in the vicinity of the windshield so as to face the rear of the vehicle, and the inside of the vehicle is photographed without changing the orientation of the surveillance camera 30, and the front glass on the driver's seat side, The area around the car is photographed through glass, rear glass, rear glass on the passenger seat side, and front glass on the passenger seat side. Also, the obstacle sensors 31 to 35 are disposed in the vicinity of each door panel, and predetermined monitoring areas 41 to 45 are determined as shown in FIG. Therefore, it is possible to detect an object that enters the monitoring areas 41 to 45 based on the obstacle sensors 31 to 35.

  The captured image acquired by the imaging unit 11 is stored in the memory 15. The captured image stored in the memory 15 is segmented by the image segmenting unit 17 into a plurality of window area images W <b> 1 to W <b> 5 formed by the window portion of the automobile in the captured image. Since the divided window area images W1 to W5 are images originally taken by one monitoring camera 30 provided near the windshield as described above, the images are taken from an oblique direction that is not perpendicular to the window direction. Some include images and have distortion. Therefore, the distortion correction unit 18 performs distortion correction on the divided window area images W1 to W5.

  FIG. 10A is a diagram illustrating an example of an image photographed by the photographing unit 11. Since the monitoring camera 30 is arranged from the vicinity of the windshield to the rear side of the vehicle, the photographed image includes the driver's seat and the passenger's seat, the driver's seat side front glass (monitoring window 51), and the driver seat side rear glass The monitoring window 52), the rear glass (monitoring window 53), the rear glass on the passenger seat (monitoring window 54), and the front glass on the passenger seat (monitoring window 55) are shown. Next, as shown in FIG. 10 (b), the above-described image segmentation unit 17 segments each window as window region images W1 to W5. The cut window region images W1 to W5 are distorted using a known image processing technique so that the image is the same as the image photographed from the front as shown in FIG. Corrected images X1 to X5 are produced. Therefore, an image similar to the image captured for each of the monitoring windows 51 to 55 can be obtained by the monitoring camera 30 provided near the windshield.

  Based on the images X1 to X5 corrected by the distortion correction unit 18 and the outputs of the obstacle sensors 31 to 35, an image determined by the image selection unit 19 that an object approaching the automobile is shown. Selected. The suspicious person determination means 20 determines whether or not the object shown in the selected image is a suspicious person. As a result, the window region image that does not appear to capture the approaching object is temporarily removed from the evaluation target image, so that the arithmetic processing can be reduced and the image evaluation can be performed efficiently. When the suspicious person determination means 20 determines that the object approaching the automobile is a suspicious person, the notification unit 24 generates threat information.

  The suspicious person determining means 20 determines whether or not the object shown in the image selected by the image selecting part 19 is a suspicious person as described above. 22 and a wrinkle determination unit 23 are provided. The face detection unit 21 detects a face part from an object shown in the image selected by the image selection unit 19. Therefore, it is possible to determine whether or not the object is a person by this detection. The peeping determination unit 22 determines that it is a suspicious person who is peeping into the automobile when a hand is detected around the face detected by the face detection unit 21. For image evaluation at this time, it is checked that a region having a pixel value similar to the skin region of the face exists in the vicinity of the face, or the contour line detected in the peripheral region of the face is the shape of the hand Or check if it is similar to. The wrinkle determination unit 23 determines that the object approaching the automobile is a suspicious person because he / she is hesitating to move around the automobile for a predetermined time across a plurality of window region images. As described above, when it is determined that the object is a suspicious person, the image recording unit 16 records the photographed image photographed by the photographing unit 11 via the memory 15.

  Next, the present embodiment will be described using a flowchart. FIG. 11 is a flowchart for displaying automobile information. First, when a door lock operation is performed on the door lock device of the vehicle from the outside of the vehicle (step # 01: Yes), the door lock detection unit 9 outputs a signal to the vehicle state detection unit 3. Based on this signal, the vehicle state detector 3 determines that the vehicle is parked (step # 02). In accordance with this determination, the vehicle state detection unit 3 is switched to the display means switching unit 6 so that the display screen of the monitor 7a faces outward (step # 03). Therefore, it is possible for a person around the car to see the information displayed on the monitor 7a. Information previously set as parking information by the user is displayed on the monitor 7a (step # 04). As this parking time information, it is possible to display information desired by the user, such as parking start time, scheduled return time, parking related information such as parking purpose, and advertisement.

  Next, when the suspicious person detection unit 8 detects a suspicious person approaching the automobile (step # 05: Yes), a suspicious person detection process is performed (step # 06). Detailed description regarding the suspicious person detection processing will be described later. As a result of the suspicious person detection process, if there is a suspicious person around the car (step # 07: Yes), threat information is generated by the notification unit 24 provided in the suspicious person detection unit 8 and displayed on the monitor 7a (step # 08). ). This threat information can display the face of the suspicious person himself / herself photographed from the inside of the vehicle by the photographing means 11, or can display a picture or a character for warning the suspicious person. . The threat based on the threat information is continued until the suspicious person disappears from the vicinity of the car.

  As a result of the suspicious person detection process, if there is no suspicious person around the car (step # 07: No), if the suspicious person is photographed in the suspicious person detection process (described later) (step #) 09: Yes), the shooting of the suspicious person is terminated (step # 10). If the suspicious person is not detected in step # 05 after the shooting of the suspicious person is completed (step # 05: No), and further, if the shooting is not performed in step # 09 (step # 09: No), the automobile When the door lock is released from the outside of the automobile with respect to the door lock device (step # 11: Yes), the process is terminated. When the door lock is not released from the outside of the automobile (step # 11: No), the process returns to step # 04 and the parking time information is displayed on the monitor 7a.

  Returning to step # 01, if the door lock operation is not performed on the door lock device of the automobile from the outside of the automobile (step # 01: No), it is confirmed whether or not the automobile is in a running state. This confirmation can be recognized by, for example, an acceleration sensor, a brake mechanism, an accelerator mechanism, a gear transmission mechanism, and the like included in the automobile. If the automobile is in a traveling state (step # 12: Yes), the vehicle state detection unit 3 determines that the automobile is in a traveling state (step # 13). In accordance with this determination, the vehicle state detection unit 3 is switched to the display means switching unit 6 so that the display screen of the monitor 7a is inward of the vehicle (step # 14). Therefore, it becomes possible for the person who rides in the car to see the information displayed on the monitor 7a, and the traveling time information is displayed on the monitor 7a (step # 15). This traveling time information can be used as a setting screen for adjusting the angle of the backrest portion of the seat seat desired by the occupant, the height adjustment of the seat seat, or a touch panel for opening and closing the window. It is also possible to display car navigation information and the like of a navigation system provided in a car, and display video and sound information from an audiovisual device. If the automobile is not in a running state in step # 12 (step # 12: No), the process is terminated as it is.

  FIG. 12 is a flowchart regarding suspicious person detection. First, the obstacle sensors 31 to 35 included in the sensor unit 12 start detecting an object approaching the automobile (step # 21). If the object falls within a predetermined range set in advance by the user (step # 22: Yes), the object approach determination unit 13 captures a signal indicating the approach of the object based on the output signals of the obstacle sensors 31 to 35. It is output to the control unit 14. Upon receiving this signal, the imaging control unit 14 outputs a control signal to the imaging means 11. The photographing means 11 is activated based on this control signal and starts photographing (step # 23). On the other hand, if there is no approach of the object within the predetermined range (step # 22: No), the process returns to the flow for displaying the vehicle information.

  When the photographing means 11 is activated, the monitoring camera 30 disposed so as to face the rear of the vehicle in the vicinity of the windshield shoots an object approaching the automobile. The acquired captured image is stored in the memory 15, and is segmented as window area images W1 to W5 by the image segmenting unit 17 (step # 24). Since these window area images W1 to W5 are images taken by the monitoring camera 30 facing the rear in the vehicle, the window area images that are not in the front direction (rear glass direction) from the monitoring camera 30 (front glass on the driver's seat side, driver side) Some of the rear glass, the rear glass on the passenger seat side, and the front glass on the passenger seat side have distortion like an image viewed from an oblique direction that is not perpendicular to the window direction. This distortion is corrected by the distortion correction unit 18 using a known image processing method (Step # 25), and distortion-corrected images X1 to X5 are produced as images taken from a direction perpendicular to the window direction. Is done.

  Based on the distortion-corrected images X1 to X5 and the detection by the obstacle sensors 31 to 35, an image showing an approaching object is specified (step # 26), and the image selection unit 19 selects the image. The Next, the suspicious person determination means 20 determines whether or not the approaching object shown in the specified image is a suspicious person through face detection (step # 27). Here, the determination routine in the suspicious person determination means 20 will be described later. When the suspicious person judging means 20 judges that the object appearing in the image is a suspicious person (step # 28: Yes), the image recording unit 16 shows the suspicious person photographed by the photographing means 11 via the memory 15. A captured image is recorded (step # 30). Further, threat information is generated by the notification unit 24 (step # 31), and the process returns to the flow for displaying the information for the car.

  On the other hand, when the suspicious person judging means 20 judges that the object shown in the image is not a suspicious person (step # 28: No), the photographing means 11 finishes photographing (step # 29) and displays the vehicle information. Return to the flow for.

  Next, determination of a suspicious person by the suspicious person determination means 20 will be described using a flowchart. FIG. 13 is a flowchart for determining a suspicious person. In step # 26 of FIG. 12, an image showing an approaching object is identified based on the distortion corrected images X1 to X5 and detection by the obstacle sensors 31 to 35, and the image selection unit 19 selects the image. Then, the face detection unit 21 included in the suspicious person determination unit 20 performs face detection from the selected image. If the face is not shown in the image selected by the image selection unit 19 (step # 41: No), the suspicious person determination means 20 determines that the object is not a suspicious person (step # 42), and the suspicious person detection flow is performed. Return.

  If a face appears in the image selected by the image selection unit 19 (step # 41: Yes), the peeping determination unit 22 determines whether or not a hand is captured around the face. If a hand is captured around the face (step # 43: Yes), the suspicious person determination means 20 determines that the object is a suspicious person (step # 46), and returns to the suspicious person detection flow. If the hand is not captured around the face (step # 43: No), the eyelid determining unit 23 determines whether or not the object is wandering around the automobile. If the object is wandering around the car (step # 44: Yes), the suspicious person determination means 20 determines that the object is a suspicious person (step # 46), and returns to the suspicious person detection flow. If the object does not hesitate around the automobile (step # 44: No), it is determined whether the object is around the automobile for a predetermined time. If there is an object around the car for a predetermined time (step # 45: Yes), the suspicious person determination means 20 determines that the object is a suspicious person (step # 46), and returns to the suspicious person detection flow. On the other hand, if there is no object around the car for a predetermined time (step # 45: No), the suspicious person determination means 20 determines that the object is not a suspicious person (step # 42), and returns to the suspicious person detection flow. In this way, the suspicious person determination means 20 can determine whether or not the object approaching the automobile is a suspicious person based on the image selected by the image selection unit 19.
