  The present invention relates to a display control device, a display control method, and a display control program.

  In recent years, in-vehicle devices have been equipped with a head-up display that displays an image on a windshield and provides traffic information and dangerous goods information to the driver. Moreover, there are central vision and peripheral vision as the nature of the human visual field. Central vision has high spatial resolution and is excellent in object recognition, and peripheral vision is excellent in capturing movement and position of objects. Considering the nature of this field of view, it is possible to recognize what an object is even without directing the line of sight to the object existing in peripheral vision (derived from the detailed information of the object present in peripheral vision and displaying it in central vision) Is already known.

  However, according to the mechanism so far, if there is a dangerous object in the peripheral vision, the driver will respond quickly after the detailed information is derived and the information displayed in the central vision is recognized. There was a problem that it was difficult to avoid.

  For example, in Patent Document 1, for the purpose of increasing the object recognition rate of a driver of a vehicle, a display control program that allows the driver to recognize the type of the target without directing his / her line of sight to the target existing in the peripheral visual field. A display control device and a display device are disclosed. In the technique of Patent Document 1, information is displayed on a display medium such as a head-up display in consideration of the nature of peripheral vision. However, the problem of avoiding danger by responding quickly to dangerous objects in peripheral vision has not been solved.

  An object of this invention is to provide the display control apparatus which can respond rapidly to the dangerous goods which exist in peripheral vision.

  In order to solve the above-described problem, a display control apparatus according to the present invention receives foreground information that can recognize an object that exists in front of the traveling direction of a vehicle and line-of-sight information that can acquire a driver's line of sight An object recognition unit that recognizes a predetermined object from the foreground information, an object determination unit that determines whether or not the recognized predetermined object satisfies a specific condition, and the foreground information using the line-of-sight information A central vision / peripheral vision determination unit that determines a central vision range and a peripheral vision range for information, and an object that is determined to satisfy the specific condition by the object determination unit is the central vision range and the peripheral vision A display control unit that performs control to determine which of the visual range is present and to display different notification objects according to the determination result.

Hereinafter, embodiments will be described with reference to the drawings. For clarity of explanation, the following description and drawings are omitted or simplified as appropriate. In the drawings, components having the same configuration or function and corresponding parts are denoted by the same reference numerals, and description thereof is omitted.
One aspect of the display control device of the present invention determines an object satisfying a specific condition with respect to foreground information in a traveling direction of a vehicle, and determines a range of central vision and a range of peripheral vision from a driver's line of sight. Control is performed to display different notification objects depending on whether an object satisfying the above condition exists in the central vision range or the peripheral vision range.
For example, the display control device of the present invention determines the range of the central vision and the range of the peripheral vision from the driver's line of sight with respect to the foreground information in the traveling direction of the vehicle. By creating a danger notice (for example, a notice with movement) that is different from the dangerous goods present in the central vision, the danger notice is displayed on top of the dangerous goods to quickly notice the presence of the dangerous goods. Foreground information is information capable of recognizing (detecting) an object existing in front of the traveling direction of the vehicle. For example, image information obtained by photographing the front of the traveling direction of the vehicle, or a sensor such as a radar or a sensor. The sensing information of the object detected by. Hereinafter, each embodiment will be described in detail with reference to the drawings.

Embodiment 1. FIG.
Embodiment 1 demonstrates as an example the case where the foreground image which image | photographed the front of the advancing direction of a vehicle is used as image information.
FIG. 10 is a diagram illustrating a hardware configuration example of the entire system according to an embodiment of the present invention. This system includes a display control device 100, a windshield 200, a front photographing camera 201, a line-of-sight recognition camera 202, a mirror 203, and a laser light source 204.
The laser light source 204 has a light emitting element inside, and each light emitting element is a display device in which lighting timing and light emission intensity are controlled by the display control device 100.
The front photographing camera 201 photographs the front through the windshield 200.
The line-of-sight camera 202 captures an area including the periphery of the driver's eyes.
The mirror 203 reflects the laser beam output from the laser light source and irradiates the windshield 200.

FIG. 1 is a diagram for explaining the system configuration of the display control apparatus 100.
The display control apparatus 100 includes an object recognition unit 101, a risk prediction unit 102, a central vision / peripheral vision determination unit 103, a danger notification object creation unit 104, and a display control unit 105. The display control apparatus 100 is configured to receive a foreground image and line-of-sight information that can acquire the driver's line of sight.

  The object recognition unit 101 receives a foreground image and recognizes a predetermined object from the foreground image in the traveling direction of the vehicle. Information on a predetermined object (hereinafter referred to as “target object information” as appropriate) is determined in advance and stored in the object recognition unit 101 or a storage area in the display control apparatus 100 that can be referred to by the object recognition unit 101. The In addition, the object recognition unit 101 identifies the position and relative speed of the recognized object.

The danger prediction unit 102 predicts whether or not the object recognized by the object recognition unit 101 is dangerous based on information determined to be dangerous. The danger prediction unit 102 is an example of an object determination unit that determines whether a predetermined object recognized by the object recognition unit 101 satisfies a specific condition.
“Prediction” in one embodiment of the present invention means determining whether or not a specific condition is satisfied based on information determined to be dangerous. Information determined to be dangerous (hereinafter referred to as “dangerous substance definition information” as appropriate) is an example of a specific condition, and is predetermined and can be referred to in the risk prediction unit 102 or the risk prediction unit 102. The data is stored in a storage area in the display control device 100. The information determined to be dangerous includes, for example, information (threshold value or the like) used for determining whether or not it is dangerous based on the position of the recognized object (distance from the vehicle) and the relative speed. Moreover, the information which sets so that a priority may be changed with the kind of object (a person's priority is higher than a vehicle etc.) may be included.

  The central vision / peripheral vision determination unit 103 receives the visual line information and the foreground image, and determines the central vision range and the peripheral vision range with respect to the foreground image from the driver's visual line. The danger notice creation unit 104 creates a danger depending on whether the object predicted to be dangerous by the danger prediction unit 102 exists in the central vision range or the peripheral vision range determined by the central vision / peripheral vision determination unit 103. Create a notification. The display control unit 105 controls the laser light source so that the danger notification material created by the danger notification material creation unit 104 is displayed.

  FIG. 2 is a flowchart for explaining a processing flow for displaying a danger notice for one foreground image. The display control apparatus 100 reads the foreground image photographed by the front photographing camera 201 after starting the processing (S101). On the other hand, the driver's line-of-sight information photographed by the line-of-sight camera 202 is read (S102). When the read foreground image and line-of-sight information are input to the object recognition unit 101 or the central vision / peripheral vision determination unit 103, the object recognition unit 101 or the central vision / peripheral vision determination unit 103 starts processing.

  The central vision / peripheral vision determination unit 103 identifies where the driver's line of sight is directed in the foreground image acquired in step S101 from the driver's line of sight information acquired in step S102, and determines the central vision of the foreground image. The range and the range of peripheral vision are determined, and the determined result is output to the danger notice creation unit 104 (S103). The object recognizing unit 101 refers to the target object information and recognizes whether a predetermined object exists in the foreground image acquired in step S101 (S104). If an object exists (S104) YES), the information of the recognized object is output to the danger prediction unit 102.

  The danger prediction unit 102 receives information on the recognized object from the object recognition unit 101, refers to the dangerous object definition information, predicts whether or not the recognized object is dangerous (S105), When it is predicted that at least one or more vehicles are dangerous for the vehicle (YES in S105), information related to the dangerous object (hereinafter referred to as “dangerous material” as appropriate) is output to the danger notification material creation unit 104. . The danger notification object creation unit 104 determines whether the dangerous object exists in the central vision range or the peripheral vision range based on the central vision range and the peripheral vision range of the foreground image (S106). . The danger notice creation unit 104 creates a danger notice object for central vision (S107) when the dangerous substance exists in the central vision range (YES in S106), and (NO in S106), a danger notice for peripheral vision is created (S108), and the display control unit 105 sets the laser light source 204 so that the created danger notice is displayed at a predetermined position on the windshield. Control is performed (S109). A notification that has been output once may not be changed when the field of view moves. If there are a plurality of dangerous materials predicted by the risk prediction unit 102, the danger notification material creation unit 104 repeats the processing of steps S106 to S108 for the number of dangerous materials. The display control unit 105 controls the laser light source 204 so that the danger notification object created in step S107 or step S108 overlaps the foreground danger object (S109), and ends the process.

  In addition, the display control apparatus determines that the object is not recognized by the vehicle as a result of the object recognizing unit 101 not recognizing a predetermined object in the foreground image (NO in S104) or the risk predicting unit 102 predicting the dangerous object. If there is no dangerous substance (NO in S105), the process is terminated at that time. Note that FIG. 2 shows processing for one foreground image. When processing for a plurality of continuous foreground images is performed, the display control apparatus 100 returns to the start without finishing after step S109.

  Further, in order to process a plurality of foreground images, the display control device uses each foreground image and the latest (latest) line-of-sight information when each foreground image is received. And a danger notice is created and displayed. For example, when performing processing on a plurality of continuous foreground images, the display control device 100 corresponds to the position of the line of sight that changes, even in the same dangerous object, in the range of central vision or the range of peripheral vision. Create and display different danger notices accordingly. Specifically, the central vision / peripheral vision determination unit 103 determines the range of central vision or peripheral vision for the foreground image from the driver's gaze indicated by the gaze information using the foreground image and the latest gaze information. . The display control device is preferably configured to hold the previously received line-of-sight information (most recent line-of-sight information) in the storage area until new line-of-sight information is received.

  Therefore, when the position of the line of sight changes and the range of central vision and peripheral vision changes, the danger notification object is changed depending on whether the same dangerous object exists in the central vision or peripheral vision at that time. Can be displayed. Thereby, even when the line of sight changes, it helps to make an appropriate determination for the dangerous goods. Also, even if the presence of dangerous goods changes between central vision and peripheral vision according to the movement of dangerous goods or the driver's line of sight, different danger notices are created corresponding to the changes. Therefore, the driver can quickly grasp and deal with dangerous objects existing in the entire foreground to avoid danger.

3 and 4 are diagrams for explaining a specific example of determining the range of central vision and the range of peripheral vision.
When the image of FIG. 3 can be acquired as the foreground of the vehicle and the driver's line of sight is directed to the position marked with a cross, the range of central vision and the range of peripheral vision are determined as shown in FIG. Central vision is generally known to be about 20 degrees in the vertical and horizontal directions from the line of sight, and the peripheral visual field is about 130 degrees in the vertical direction and about 180 degrees in the horizontal direction. The determination unit 103 can identify the range if the line-of-sight position is known. Next, a specific example of the danger notification object will be described with reference to FIGS. Here, it is assumed that humans and vehicles are predetermined in the dangerous substance definition information as dangerous goods.

  5 and 6 are diagrams for explaining specific danger notification objects for central vision. FIG. 5 is an example expressing the types of dangerous materials such as humans and vehicles. When the circle in the white chain line is within the range of central vision, for example, “human is a red rectangle” or “vehicle is yellow” "Nomaru" is created as a danger notice. The central vision takes into account the property of recognizing an object, and expresses detailed information on the dangerous object by the shape and color of the danger notification object.

  FIG. 6 is an example expressing the types of danger levels of dangerous goods. When the circle in the white chain line is within the range of central vision, for example, a dangerous object existing in central vision is surrounded by a “red circle” with a high-risk object (here, a human being) A danger notice object is created by enclosing a low-risk object with a “yellow circle”. Further, the danger notification material creating unit 104 may create a danger notification material having a different shape or color depending on the type and the degree of danger of the dangerous material. For example, the degree of danger may be divided among the same types of dangerous goods, and among humans, a person driving a vehicle such as a motorcycle or a bicycle may be distinguished from other persons. As shown as an example in FIGS. 5 and 6, the additional information for the dangerous goods is displayed to help the driver make a more appropriate determination.

  FIG. 7 is a diagram for explaining a specific danger notice object for peripheral vision. When the inside of the white circle is the range of central vision, the danger notification object is "Round to rectangle (changes shape) from round to rectangular" for the dangerous objects (targets are human and vehicle) in the outer peripheral vision Create as. FIG. 7 shows a case where a person on a motorcycle displays a circle on the left image and a rectangle on the right image. Considering the nature that peripheral vision is excellent in capturing movement and position, it expresses where the danger exists by the movement of the danger notification object. As another example of the danger notification object, it may be possible to express a movement by a change in size or blinking. In addition, the danger notification object creation unit 104 may create a danger notification object as a moving danger notification object by one or a plurality of combinations such as a change in shape, a change in size, and blinking. As shown as an example in FIG. 7, by displaying a moving danger notification object at the position of the dangerous object in the range of peripheral vision, it helps the driver to quickly avoid danger.

  When the driver's field of view moves, if the danger notice is switched accordingly, the display in the driver's field of view is frequently switched, which may adversely affect the driver's recognition. Therefore, another method for creating either a peripheral vision danger notification object or a central vision danger notification object will be described.

  FIG. 8 is a flowchart for explaining another processing flow for displaying a danger notice for one foreground image. The danger prediction unit 102 receives the information of the recognized object from the object recognition unit 101, refers to the dangerous object definition information, and predicts whether or not the recognized object is dangerous (S201). If at least one of the recognized objects is recognized as dangerous for the vehicle (S201), the danger notification object creating unit 104 determines whether the recognized dangerous object is in the range of peripheral vision or central vision. Regardless of whether or not a danger notification object for central vision is created for the dangerous object, the display control unit 105 controls the display of the danger notification object (S202). Next, when the target dangerous object is present in the peripheral vision for a predetermined time (YES in S203), the display control unit 105 displays the danger notification object for the target dangerous object for central vision. The danger notification object is switched to the danger notification object for peripheral vision (S204). If the target dangerous object does not exist in the peripheral vision for a predetermined period of time (NO in S203), the display control unit 105 ends the process without switching the danger notification object for central vision.

  In this flow, for dangerous goods that have been switched to peripheral vision danger notices, even if the driver's field of view has moved and moved to the central vision range, Do not switch to the danger notice for central vision. Thus, even when the driver's field of view moves, switching between central vision and peripheral vision does not occur frequently, and the adverse effects on the driver's recognition caused thereby can be reduced.

The reading device 114 is a means for reading (receiving) an image photographed by the front photographing camera 201 or the line-of-sight photographing camera 202 shown in FIG. The reading device 1141 outputs the read image and line-of-sight information to the object recognition unit 101 or the central vision / periphery vision determination unit 103. When the display control device uses the sensing information as foreground information (described later in Embodiment 2), the reading device 114 is configured to acquire information from the sensor instead of the front photographing camera 201.

  The storage device 115 is a storage unit that stores various programs, input image data, and various digital data to be processed, and includes a hard disk drive (HDD), a flash memory, and the like.
