Description

  The present invention relates to an image display technique for a vehicle that transmits information to a driver by displaying an image so as to be superimposed on a real landscape.

  Conventionally, there is a system that provides information about various facilities to a driver of a vehicle. In particular, as the traffic network has developed in recent years and the driver has moved freely over a wide area, it has become difficult for the driver to constantly grasp the complicated and changing road conditions. Navigation systems that provide guidance information when moving to the public are known and are in widespread use.

As an advanced form of such a navigation system, a system has been developed that displays an image in the vicinity of the front window so as to overlap the actual scenery. For example, Patent Document 1 has developed a device that captures an actual scene with a camera and displays an image representing attribute information of the structure so as to be superimposed on the structure in the actual scene.
JP 11-0665431 A

  However, in the system as described above, a facility-related image is displayed unconditionally when the facility existing in the field of view becomes visible. Therefore, for example, when the facility is not visible from the driver due to an obstacle, the driver cannot obtain any information about the facility. On the other hand, when it is determined whether or not the facility is approved for viewing based only on the map data, a problem arises when the facility cannot be visually recognized by the driver due to an obstacle.

  In other words, it can be determined that it is visible based on the map data, but if the facility-related image is displayed as usual when the facility is not actually visible due to the obstacle, the facility-related image and the obstacle appear to overlap. As a result, the driver is given the impression that the obstacle is the facility. This can be a source of confusion for the driver.

The present invention has been made to solve the above problems, and when displaying an image related to a facility superimposed on a real landscape, even if the facility cannot be visually recognized due to an obstacle, the driver is not confused. An object of the present invention is to provide a vehicle image display device that can provide information on facilities and improve convenience.

In order to achieve the above object, in the present invention, in order to provide information on facilities existing in front of the vehicle, the vehicle driver can see the actual scenery visible through the window, An image display device for a vehicle that displays a facility-related image related to the facility, and when it is determined that the facility can be viewed with reference to map data, a predetermined facility-related image is displayed and the facility is visually recognized If it is determined to be impossible, the display control means performs display control in a display mode in which the predetermined facility-related image is not displayed, and the display control means determines that the display is visible with reference to the map data. An obstacle that becomes an obstacle when the facility is visually recognized is detected, and when the facility cannot be visually recognized by the obstacle, the obstacle does not overlap with the obstacle, and there is no obstacle. Displaying the property related image in a position nearest from the position where the come the facility related image is displayed, characterized in.

The display control means, when the facility is not visible due to the obstacle, when a position that does not overlap with the obstacle is a predetermined distance or more away from a position where the facility-related image is originally displayed if there is no obstacle Is characterized in that display of the facility-related image is restricted.

In order to achieve the above object, another vehicular image display apparatus according to the present invention superimposes an actual scenery that can be viewed through a window from a driver of the vehicle in order to provide information on a facility existing in front of the vehicle. The vehicle image display device displays a facility-related image related to the facility so that the facility can be viewed with reference to map data, so that a predetermined facility-related image is displayed. When it is determined that the facility is not visible, the display control unit performs display control in a display mode in which the predetermined facility-related image is not displayed, and the display control unit refers to the map data. When an obstacle that becomes an obstacle when visually recognizing the facility that is determined to be visually recognized is detected, and the facility cannot be visually recognized due to the obstacle, the facility is set based on a preset priority of the facility. Te, characterized by regulating the display of the facility related images.

Vehicle guidance means for guiding the vehicle using a visually observable facility as an index is further provided, and the display control means is configured to display the facility-related image for the facility that is used as the vehicle guidance index by the vehicle guidance means. It is not subject to display restrictions.

In order to achieve the above object, still another image display device for a vehicle according to the present invention provides an actual scene viewable from a driver of the vehicle through a window in order to provide information on a facility existing in front of the vehicle. An image display device for a vehicle that displays a facility-related image related to the facility so that the facility is visible, and when it is determined that the facility is visible with reference to map data, a predetermined facility-related image is displayed. displaying, when said facility is determined to invisible includes a display control unit for controlling the display in a display mode that does not display the predetermined facility related image, wherein the display control unit, the facility is the If not possible viewing by an obstacle, the while regulating the display of the facility related image, the obstacle becomes an obstacle when viewing the been the facility determines visible with reference to the map data Display the facility-related image when it is estimated that the facility is not visible due to the obstacle, but is not visible again due to the obstacle within a predetermined time. It is characterized by continuing regulation.

  According to the present invention, since an image related to a facility is displayed so as to be superimposed on the actual scenery, the driver can acquire information on the facility with a small amount of line of sight movement during driving, thereby improving safety. be able to. In addition, if the facility is invisible due to an obstacle, the display format of the facility-related image is changed, so even if the facility cannot be visually recognized due to an obstacle, information is provided in an appropriate form without causing confusion to the driver And convenience can be improved.

  Here, if a radar or a camera is used, an obstacle can be reliably detected. Further, if an obstacle image or a facility image is stored in advance in a storage unit and compared with a captured image, the obstacle can be detected more reliably.

  In addition, if the facility-related image is displayed at a position that does not overlap the obstacle when the facility cannot be visually recognized due to the obstacle, it is possible to avoid confusion between the facility and the obstacle.

  Furthermore, if the facility-related image is displayed at a position closest to the position where the facility-related image should be displayed if there are no obstacles, the driver can be surely informed where the facility-related image indicates the facility. be able to. In addition, it is possible to avoid a situation in which the facility indicated by the facility-related image cannot be recognized.

  Furthermore, when the facility is invisible due to an obstacle, if the display of the facility-related image is restricted, the driver's confusion due to the recognition of the obstacle as the facility can be avoided.

  In particular, if the display of facility-related images is restricted based on the priority of the facility set in advance, the display of facility-related images is uniformly restricted for all facilities that cannot be viewed due to obstacles. Can prevent harmful effects. For example, for facilities that are used as vehicle guidance indicators (such as destinations and waypoints) by vehicle guidance means, if the display of facility-related images is restricted, there is a possibility that important information for the driver cannot be obtained. Therefore, it can be excluded from display restrictions and the convenience of the driver can be improved.

  In addition, even if the facility moves from a state where it cannot be seen due to an obstacle to a state where it can be seen, or if the facility cannot be seen immediately due to an obstacle, the facility-related image display regulation can be continued. Thus, it is possible to prevent the driver from feeling uncomfortable due to repeated changes in the display mode.

  Hereinafter, an information providing system according to an embodiment of the present invention will be described with reference to the drawings. In the embodiment described below, a predetermined role / function is assigned to each element constituting the system, but some of these functions can be assigned to any element as a system. It is sufficient for achieving the effect and is not limited to this embodiment. In other words, in response to technical advancement of each element in the future and enhancement of infrastructure development, the element in which each function is mounted varies, and the new technical idea of the present invention is a modification of these. , Including additions and modifications.

There are text information that introduces the facility, and information that includes images and features of the facility. If the information providing device 10 does not include the database 13, the facility provided by the operation switch 15 and the current location measured by the positioning device 12 are transmitted from the communication interface 18 via the network 20 to the information providing center 30. To be calculated by the information providing center 30.

  At this time, the information providing center 30 performs calculations using the center CPU based on various data stored in the unique database 32 and transmits the result to the information providing apparatus 10 via the communication interface 33 and the network 20. Will be.

  The information providing apparatus 10 also superimposes a camera 20 that captures a real landscape in the traveling direction of the vehicle 10b, a radar 21 that measures a distance to an object in the traveling direction of the vehicle 10b, and a window of the vehicle 10b. An image display device 22 for projecting facility-related images is provided. Further, the information providing apparatus 10 includes a memory 19 that stores a captured image of a real landscape captured by the camera 20.

  The information providing center 30 stores a CPU for calculation control, a center CPU 31 having a ROM for storing fixed values and a RAM for temporary storage, and data for extracting position information or searching for position information controlled by the center CPU 31. A communication interface 33 for communicating with the information providing apparatus 10 via the database 32 and the network 20. In the present embodiment, the details of the display procedure of the facility-related image regarding the facility using the head-up display device using the windshield of the automobile, which is provided as the image display device 22, are described in Patent Document 1 and Japanese Patent No. Since it is described in the Kaihei 8-83397 publication, it is omitted here.

  In the present embodiment, it is possible to perform information providing processing by the information providing apparatus 10 alone mounted on the vehicle 10b, and the database 13 stores data necessary for performing a normal navigation function, for example, Map data, road data, facility-related data, and the like are stored, and guidance information such as route information can be displayed using the display 16. The database 19 stores facility-related images such as images captured by the camera 20, obstacle images, facility images, features, and attribute information, and mainly through the window using the image display device 22. Used to superimpose and display in real scenery. Therefore, in the following, an information providing example in the case where the information providing apparatus 10 of the vehicle 10b alone realizes the information providing system according to the present invention will be described.

<Operation example 1 of information providing system>
FIG. 3 is a schematic diagram showing a state when facility-related information is superimposed and displayed on an actual scenery visually recognized through a window of a vehicle such as an automobile. FIG. 4 is a flowchart for explaining a first operation procedure of information providing processing performed using the information providing apparatus 10 according to the present embodiment.

  First, when the information providing apparatus 10 of the present information providing system is activated, first, the current position information of the vehicle 10b is acquired by the positioning apparatus 12, and is passed to the apparatus CPU11. Then, the device CPU 11 reads map data in the vicinity of the current location from the map data stored in the database 13 (step S11). The process of detecting the current location and reading the map data near the current location is continuously performed while the information providing apparatus 10 is activated.

  Next, the apparatus CPU 11 stores in the database 13 position information of a facility such as a guide destination that the user (or the driver 10a) drives the vehicle 10b set by using the operation switch 15 and is about to leave. The map data is calculated by using the map data (step S12). Then, the device CPU 11 determines whether or not the facility is located around the current location (step S13). Specifically, it is determined whether or not the location information of the facility is included in the map data read in step S11 (step S13).

  As a result, if it is not included (No), this process is terminated, and if it is included (Yes), the device CPU 11 further determines the position of the facility acquired in step S12 from the current location acquired in step S11. It is determined whether or not can be visually recognized in terms of distance, that is, whether or not it can be visually recognized on a map base (step S14). This determination can be made, for example, by comparing whether or not the linear distance between the current location (the position of the vehicle 10b) and the facility is within a predetermined distance (for example, a distance that a human can visually recognize).

  As a result, when it is determined that the distance is not within the visible distance (No), the present process is terminated. When it is determined that the distance is within the visible distance (Yes), the navigation device CPU 11 determines that the current position is It is determined whether or not the facility is directly visible, that is, whether or not there is an obstacle that shields the facility between the current location and the facility (step S15).

  Here, the process for determining whether or not an obstacle exists in the present embodiment will be described. In this embodiment, the radar 21 can be used to measure the distance to an object that exists in the direction in which the facility is located. Therefore, the device CPU 11 acquires the distance from the current location to the facility from the map data stored in the database 13, compares the distance with the distance acquired using the radar 21, and compares the current location with the facility. It is determined whether an obstacle exists between them. For example, when both distances are different, that is, when the distance measured by the radar is shorter than the distance acquired from the map data, the radar 21 can be regarded as having measured the distance to the obstacle.

  Thus, the actual distance from the current location of the vehicle 10b measured using the radar 21 provided in the vehicle 10b to the object existing in the direction of the facility, and the databases 13, 23 such as the vehicle-mounted or information providing center 30 and the like. By comparing the distance from the current location to the facility acquired from the map data stored in the map, it can be suitably determined that an obstacle exists at the position of the object.

  Further, as another means for determining the presence of an obstacle, the camera CPU 20 captures a real landscape in the direction of the facility to acquire a captured image, and the apparatus CPU 11 detects the obstacle based on the acquired captured image. It can also be determined whether or not it exists. Hereinafter, the Example which determines the presence or absence of an obstruction using a captured image is described.

  As a first example, the device CPU 11 acquires images of various obstacles stored in the database 13 or acquires them from the database 32 of the information providing center 30 via the communication interface 18. You may make it determine by performing pattern collation etc. whether an obstruction exists in the part in which the plant | facility in the captured image imaged with the camera 20 is located using an image.

  As a second example, the device CPU 11 acquires an image of a facility stored in the database 13, or acquires the image of the facility acquired from the database 32 of the information providing center 30 via the communication interface 18. The presence or absence of an obstacle may be determined based on whether or not an image of the facility destination exists in a portion where the facility is located in the captured image captured by the camera 20.

  Further, as a third example, the device CPU 11 acquires images of various obstacles or facilities stored in the database 13 or acquires them from the database 32 of the information providing center 30 via the communication interface 18. The feature is extracted from the image of the obstacle or the facility, and the extracted feature is used to determine whether the obstacle or the facility exists in the portion where the facility is located in the captured image captured by the camera 20. It may be determined by performing pattern matching.

  By performing the determination as described above, a predetermined position (for example, a specified position) in a captured image of the direction of the facility (or the traveling direction of the vehicle) captured using an imaging device such as the camera 20 provided in the vehicle 10b. It is possible to suitably determine whether the object of the portion where the facility is present is an obstacle or a designated facility. That is, in this determination, images of obstacles and facilities stored in the databases 13 and 32 such as the vehicle-mounted or information provision center 30 and their characteristics are acquired, and a predetermined position in the captured image is acquired. A suitable determination can be made by comparing the images and features of the portions.

  As a result, when it is determined that there is no obstacle (No), the driver 10a is in a state where the facility can be visually recognized through the window. The image is displayed so as to be superimposed on the actual scenery (step S16). FIG. 3A is a diagram illustrating an example of a situation when the driver 10a sees the actual scenery through the window when the facility-related image of the facility is displayed as usual. As shown in FIG. 3 (a), the driver 10a displays the facility-related images (for example, “← convenience store ABC”, “hotel XX →”, etc.) superimposed on the actual scenery seen through the window. Image), the driver 10a can recognize the location of the facility without a sense of incongruity according to the display of the facility-related image relating to the facility.

  On the other hand, if it is determined that there is an obstacle (Yes), the device CPU 11 detects a predetermined display position avoiding the obstacle in the actual scenery visually recognized through the window by the driver 10 (step S17), and further Then, it is determined whether or not the detected display position is more than a certain distance from the original display position (step S18). As a result, when the detected display position is not separated from the original display position by more than a certain distance (No), the device CPU 11 displays the image using the image display device 22 so as to be superimposed on the actual scenery through the window. The facility-related image of the facility is displayed at the position detected in step S17, avoiding the obstacle portion visually recognized by the driver 10a (step S19).

  FIG. 3B shows that the vehicle (convenience store ABC) from the state shown in FIG. 3A becomes an obstacle when another vehicle cuts in front of the vehicle 10b on which the information providing device 10 is mounted. When the facility 10 is displayed by the conventional image display device when the facility is shielded and the driver 10a is not visible, the driver 10a sees the actual scenery through the window. It is a figure which shows an example of a mode. That is, since a part of “←” indicating the location of “Convenience Store ABC” is superimposed on the obstacle, the driver 10a may lose sight of the location of Convenience Store ABC or be confused. In particular, if the facility is a similar obstacle, the driver 10a is expected to become even more confused.

  Therefore, in the present embodiment, as described above, the facility-related information of the facility is displayed on the windshield while avoiding the obstacle portion. FIG.3 (c) is a figure which shows an example of a mode when the driver | operator 10a sees a real landscape through a window when the facility related image of a facility is displayed using the information provision apparatus 10 which concerns on this embodiment. It is. That is, “convenience store ABC →”, which is a facility-related image of the facility, is displayed on the windshield, avoiding the part of the interrupting car that is an obstacle.

  It should be noted that the position detected in step S17 is a position that avoids the obstacle portion on the windshield, and is preferably the closest position to the position where the facility-related image of the facility is originally displayed. In this manner, the facility-related image of the facility displayed so as to be superimposed on the actual scenery through the window visually recognized by the driver 10a of the vehicle 10b is hidden by the obstacle by displaying it avoiding the obstacle part. Sometimes, the obstacle can be displayed while avoiding the confusion of the driver 10a.

  On the other hand, when it is determined in step S18 that the detected position is a predetermined distance or more away from the original display position (Yes), the image display device 22 prohibits the display of the facility-related image of the facility and displays it. (Step S20). Thus, by preventing the display position of the facility-related image from being displayed at a position that is too far from the original position, the driver is not confused thereby.

<Operation example 2 of information providing system>
FIG. 5 is a flowchart for explaining a second operation procedure of the information providing process performed using the information providing apparatus 10. In this flowchart, the processing up to the determination of the presence / absence of an obstacle shown in step S15 is the same as the flowchart shown in FIG.

  As a result of the determination in step S15, when it is determined that there is no obstacle (No), the apparatus CPU 11 further determines whether or not the currently visible facility becomes invisible after a predetermined time has elapsed (step S21). ). If it is determined that the image cannot be viewed after a predetermined time has elapsed (No), the information display device 22 displays the facility-related image of the facility superimposed on the actual scenery that can be seen through the window in the same manner as in the past. (Step S22). On the other hand, when it is determined that the visual recognition becomes impossible after the predetermined time has elapsed (Yes), the process proceeds to step S23. Moreover, also when it determines with an obstruction existing as a result of determination in step S15 (Yes), it progresses to step S23.

  In step S <b> 23, display restriction of facility-related images displayed on the image display device 22 is performed according to the respective conditions. That is, when the facility is invisible due to an obstacle, the display of the facility-related image is restricted, so that the driver can be prevented from being confused by recognizing the obstacle as the facility.

  In particular, if the display of facility-related images is restricted based on the priority of the facility set in advance, the display of facility-related images is uniformly restricted for all facilities that cannot be viewed due to obstacles. Can prevent harmful effects. For example, vehicle guidance means for guiding a vehicle using a visually recognizable facility as an index is provided, and facilities that are used as an index for vehicle guidance by the vehicle guidance means are not subject to display restrictions on facility-related images. Like that. In other words, for facilities that are used as vehicle guidance indicators (such as destinations and waypoints) by the vehicle guidance means, if display of facility-related images is restricted, there is a possibility that important information for the driver cannot be obtained. Therefore, it can be excluded from display restrictions and the convenience of the driver can be improved.

  In addition, even if the facility moves from a state where it cannot be seen due to an obstacle to a state where it can be seen, or if the facility cannot be seen immediately due to an obstacle, the facility-related image display regulation can be continued. Thus, it is possible to prevent the driver from feeling uncomfortable due to repeated changes in the display mode.

  If it is determined in step S15 that there is an obstacle, it includes character information relating to the introduction of the name of the facility or contents, and an instruction symbol such as an extendable arrow for indicating the position of the guidance destination. For facility-related images, the driver can visually recognize the facility-related images of the facility in a suitable state at all times by changing the font of the character information or changing the position, length, or display position of the instruction symbols. It becomes possible to display easily. Alternatively, the display of facility-related images may be prohibited.

  Further, in step S23, if it is estimated that the facility is not visible due to the obstacle, but is not visible again due to the obstacle within a predetermined time, Continue to restrict image display. As a result, even if the facility changes from an invisible state to an invisible state due to an obstacle, and immediately becomes invisible due to the obstacle, the facility-related image display regulation should be continued. Thus, it is possible to prevent the driver from feeling uncomfortable due to repeated changes in the display mode.

  In addition, regarding the facility such as the final destination set by the driver 10a or a predetermined registered location, the display restriction may be prohibited and displayed without fail. As a result, the facility-related images related to the registered destination designated by the final destination or the user can be prevented from being restricted even if there are obstacles, and can always be displayed in a certain state. So you won't lose sight of those positions.

  As described above, by changing the display form of the facility-related image displayed superimposed on the actual scenery through the window, for example, even if the facility itself cannot be directly viewed by an obstacle, the display is changed and displayed. The driver can recognize the location of the facility without a sense of incongruity according to the display of the facility-related image.

  Here, FIG. 6 is a diagram for explaining a setting screen used when the user of the information providing apparatus 10 performs display setting of the facility-related image of the facility that is the guidance destination. The setting screen shown in FIG. 6 is displayed on the display 16, and the driver 10 a and other users can switch display items by operating the operation switch 15. For example, the user can arbitrarily perform various settings such as settings related to facility display items, settings related to display facilities, settings of symmetrical display areas, and settings related to the display time of facility related information.

  In the present invention, a program for realizing the functions of the above-described embodiments by a computer is recorded on a computer-readable recording medium (storage medium), and the program recorded on the recording medium is stored in the system. A computer or the like may read and execute. Computer-readable recording media include portable recording media such as a flexible disk, CR-ROM, and DVD-ROM, a storage device (recording device) such as a hard disk or volatile memory (RAM) built in the system or computer.
