JP 2000-177483 A (paragraph numbers 0010, 0034, FIG. 2, FIG. 4)

  However, since the vehicle driving support apparatus described in Patent Document 1 is basically configured to capture only a single direction with a single camera, the single camera has only a specific limited area. In order to simultaneously monitor a plurality of areas having different directions such as front and rear, for example, a plurality of cameras are necessary.

  Accordingly, an object of the present invention is to provide a vehicle driving support capable of simultaneously monitoring a plurality of regions having different directions with a single camera in view of the above-mentioned drawbacks of the vehicle driving support device according to the prior art exemplified above. To provide an apparatus.

A first characteristic configuration of the present invention is a vehicle driving support device including an in-vehicle camera capable of imaging a peripheral region of a vehicle, and a monitor screen for displaying an image captured by the in-vehicle camera to a driver,
The vehicle-mounted camera and light guide means for guiding light from a subject at a position deflected with respect to the optical axis of the vehicle-mounted camera to a light-receiving element of the vehicle-mounted camera are provided in a translucent cover of the vehicle lighting device. A control unit capable of displaying a plurality of images captured by the in-vehicle camera, including images via the light guide, on the monitor screen;
The light guide means having a partition member that separates a plurality of lights traveling to the light receiving element through different paths from each other is provided on the upstream side of the light receiving element;
The partition member has a plate shape having an end face with a predetermined width facing the light receiving element,
In the image captured by the in-vehicle camera, the captured image of the end surface constitutes a boundary line that partitions the plurality of images ,
The lighting device is a blinking direction indicator lamp, and the control unit is configured to continuously display only a captured image during lighting of the blinking direction indicator lamp on the monitor screen,
The control unit performs a filter process for converting an image portion obtained by imaging the vehicle itself based on light emitted from the directional indicator lamp that is lit, into a color tone different from the emission color of the directional indicator lamp, and the monitor. The point is to display on the screen .

Therefore, in the vehicle driving support device according to the first characteristic configuration of the present invention, the light guide means for guiding the light from the subject at the position deflected from the optical axis of the camera to the light receiving element together with the in-vehicle camera is the translucency of the lamp. Since it is arranged in the cover, the driver can simultaneously monitor a plurality of areas in one monitor screen, and more effective support for driving is provided. In addition, since the in-vehicle camera and the light guide means are disposed in the translucent cover of the vehicle lighting device, the in-vehicle camera can be easily protected from wind and rain by utilizing the airtightness of the translucent cover of the vehicle lighting device. . Moreover, if a lighting device is used in which the headlights and direction indicator lights are combined into a single unit and housed in a single translucent cover, a wide range including the side from the front of the vehicle can be effectively captured by the in-vehicle camera in the cover. it can.
In addition, since the light guide means having a partition member that separates a plurality of lights traveling toward the light receiving element via different paths from each other is provided on the upstream side of the light receiving element, a plurality of images having different imaging ranges are connected to each other. Can be prevented from being displayed on the monitor screen in a state where it is difficult to discriminate the contents of images that interfere with each other with a simple configuration in which a partition member that physically separates the lights is provided in front of the light receiving element.
Since the direction indicator light is in principle located at or near the fender of the vehicle, the monitor screen effectively monitors the direction of the side as viewed from the vehicle and the situation behind the diagonal, which is difficult for the driver to see. it can. In addition, since only the captured images are continuously displayed while the direction indicator is lit, the display image blinks in synchronization with the blinking cycle of the direction indicator even when there is little ambient light, such as at night. The phenomenon can be avoided and a clear image can be displayed on the monitor screen.
Furthermore, when the surroundings are imaged with light from the direction indicator light in a situation where the ambient light is weak, such as at night, even if a part of the vehicle itself is displayed on the monitor screen, the vehicle itself emits the direction indicator light. Since it is displayed after being converted into a color tone different from the color, it becomes easy to distinguish between surrounding obstacles and the vehicle itself, which is an effective support for parking operation and starting operation from parking.

A second characteristic configuration of the present invention is a vehicle driving support device including an in-vehicle camera capable of imaging a peripheral area of a vehicle, and a monitor screen for displaying an image captured by the in-vehicle camera to a driver,
The vehicle-mounted camera and light guide means for guiding light from a subject at a position deflected with respect to the optical axis of the vehicle-mounted camera to a light-receiving element of the vehicle-mounted camera are provided in a translucent cover of the vehicle lighting device. A control unit capable of displaying a plurality of images captured by the in-vehicle camera, including images via the light guide, on the monitor screen;
The light guide means having a partition member that separates a plurality of lights traveling to the light receiving element through different paths from each other is provided on the upstream side of the light receiving element;
The partition member has a plate shape having an end face with a predetermined width facing the light receiving element,
In the image captured by the in-vehicle camera, the captured image of the end surface constitutes a boundary line that partitions the plurality of images ,
The lighting device is a blinking direction indicator lamp, and the control unit suppresses an exposure amount by the light receiving element while the direction indicator lamp is lit based on a drive signal for blinking the direction indicator lamp, and the direction. It is configured to change and set the aperture or shutter speed of the in-vehicle camera so as to increase the exposure amount by the light receiving element while the indicator light is turned off.
The control unit performs a filter process for converting an image portion obtained by imaging the vehicle itself based on light emitted from the directional indicator lamp that is lit, into a color tone different from the emission color of the directional indicator lamp, and the monitor. The point is to display on the screen .

Therefore, in the vehicle driving support device according to the second characteristic configuration of the present invention, the light guide means for guiding the light from the subject at the position deflected from the optical axis of the camera to the light receiving element together with the in-vehicle camera is the translucency of the lamp. Since it is arranged in the cover, the driver can simultaneously monitor a plurality of areas in one monitor screen, and more effective support for driving is provided. In addition, since the in-vehicle camera and the light guide means are disposed in the translucent cover of the vehicle lighting device, the in-vehicle camera can be easily protected from wind and rain by utilizing the airtightness of the translucent cover of the vehicle lighting device. . Moreover, if a lighting device is used in which the headlights and direction indicator lights are combined into a single unit and housed in a single translucent cover, a wide range including the side from the front of the vehicle can be effectively captured by the in-vehicle camera in the cover. it can.
In addition, since the light guide means having a partition member that separates a plurality of lights traveling toward the light receiving element via different paths from each other is provided on the upstream side of the light receiving element, a plurality of images having different imaging ranges are connected to each other. Can be prevented from being displayed on the monitor screen in a state where it is difficult to discriminate the contents of images that interfere with each other with a simple configuration in which a partition member that physically separates the lights is provided in front of the light receiving element.
In synchronization with the blinking timing of the direction indicator lamp, the exposure amount is reduced during lighting, and the exposure amount is increased during extinction, so that images are continuously captured while the blinking direction indicator lamp is on and off, Even when displayed on the monitor screen in real time, it is possible to display a relatively stable and good image with little variation in average luminance.
Furthermore, when the surroundings are imaged with light from the direction indicator light in a situation where the ambient light is weak, such as at night, even if a part of the vehicle itself is displayed on the monitor screen, the vehicle itself emits the direction indicator light. Since it is displayed after being converted into a color tone different from the color, it becomes easy to distinguish between surrounding obstacles and the vehicle itself, which is an effective support for parking operation and starting operation from parking.

Another characteristic configuration of the present invention is that the vehicle lighting device is a vehicle lighting device in which a headlight and the direction indicator lamp are housed in one light-transmitting cover as a unit.
With this configuration, not only can the in-vehicle camera be easily protected from wind and rain by utilizing the airtightness of the translucent cover of the vehicle lighting device, but the in-vehicle camera in the cover covers a wide range including the side from the front of the vehicle. Can effectively capture images.

  Another characteristic configuration of the present invention includes an image processing unit that converts a primary captured image obtained through the reflection unit as the light guide unit into a display image, and the image processing unit includes the end surface of the partition member. A marker indicating the boundary between the plurality of images is created based on the captured image and displayed on the monitor screen together with the display image.

  With this configuration, a plurality of images displayed adjacent to each other on the monitor screen, for example, a captured image that shows the front of the vehicle and another captured image that shows the side of the vehicle may be improved by image processing. Since it can be clearly divided by a marker such as a vivid color created prominently, the driver can easily identify these different images. In addition, since the marker is created based on the captured image of the end face of the partition member, the position of the marker is always determined more accurately.

Another characteristic configuration of the present invention is that the image processing unit converts the primary captured image into a display image obtained by horizontally inverting and displaying the image on the monitor screen.
Another characteristic configuration of the present invention is that the partition member is formed of a colored transparent material.
With this configuration, a clear image formed by imaging the end face of the partition member can be displayed as it is without being processed by image processing.

Another characteristic configuration of the present invention is that light projecting means for irradiating light from the other end surface of the partition member toward the light receiving element side end surface of the partition member is provided.
If it is this structure, the end surface by the side of the lens of a partition member can be imaged as a clearer image.

In another feature of the present invention, the light guiding means reflects each of light from a plurality of subjects at a position deflected with respect to the optical axis of the in-vehicle camera to the light receiving element of the in-vehicle camera. A plurality of guiding mirrors, the partition member separating a plurality of light reflected by each of the plurality of mirrors from each other, and a plurality of lights reflected by each of the plurality of mirrors and the light A light beam that does not pass through the light guide means from the subject in front of the in-vehicle camera is integrally provided with a horizontal partition that separates the light that does not pass through the light guide means from the subject in front of the in-vehicle camera; The light guided by the light guiding means is simultaneously guided to the light receiving element.

  With this configuration, an image through the light guiding unit and an image without the light guiding unit can be simultaneously displayed on the monitor screen, so that a large number of directions can be monitored with a single vehicle-mounted camera. For example, if an in-vehicle camera is installed so that its optical axis faces an important monitoring target area, the light from the area is guided directly to the light receiving element without passing through the light guiding means. The imaging under good conditions can be performed without being affected by absorption or irregular reflection of some wavelengths.

In another characteristic configuration of the present invention, the light guide unit is disposed above the optical axis of the in-vehicle camera, and light from a subject in front of the in-vehicle camera directly passes through the light guide unit without passing through the light guide unit. It is in the point led to the light receiving element.
If it is this configuration, generally the sky with low importance as driving support information is not imaged by being blocked by the light guiding means, instead, the vehicle rear, side, deflected with respect to the optical axis of the in-vehicle camera, A subject positioned obliquely forward is guided by the light guide means and imaged. In addition to this, since a subject in front of the in-vehicle camera is also imaged, as a result, a wide range surrounding the vehicle can be monitored simultaneously.

The best mode for carrying out the present invention will be described below with reference to the drawings.
A vehicle 1 shown in FIG. 1 includes camera units 5 capable of capturing an image of a peripheral region of the vehicle at both left and right ends on the front side. In addition, a liquid crystal monitor 8 (display screen) that displays an image captured by the camera unit 5 to the driver is installed on the instrument panel of the driver's seat. The camera unit 5 includes a right camera unit 5R and a left camera unit 5L.
As shown in FIG. 2, the camera units 5 </ b> R and 5 </ b> L are disposed behind the translucent cover 2 a of the direction indicator lamp 2 and are disposed outside the video camera 6 and the lens 6 a of the video camera 6. It has a pair of plane mirrors 7a and 7b (light guide means). At least the lens 6a and the plane mirrors 7a and 7b of the video camera 6 are protected from wind and rain and dust by being installed in the translucent cover 2a of the direction indicator lamp 2 of the vehicle 1. Of course, a blinking lamp 9 of the direction indicator lamp 2 is also arranged behind the translucent cover 2a.

Hereinafter, the right camera unit 5R will be described as an example. As shown in FIGS. 2 and 3, the optical axis X2 of the lens 6a of the video camera 6 is horizontal and along the side surface direction of the vehicle 1, particularly here with respect to the center line X1 in the front-rear direction of the vehicle 1 It is installed vertically.
The pair of plane mirrors 7a and 7b are arranged so as to be inclined with respect to the optical axis X2 from a predetermined position on the optical axis X2, thereby allowing light from the subject at a position deflected with respect to the optical axis of the lens 6a. A light guide means is provided which leads to a lower region of one CCD 6b (light receiving element). Here, the pair of plane mirrors 7a and 7b are arranged in a “<” shape in a direction of about 45 ° in a plan view, and one plane mirror 7a connects the image of the subject in front of the vehicle 1 to the CCD 6b. is an image, the other flat surface mirror 7b is focusing an image of an object behind the vehicle 1 to CCD6b. Of course, it is also possible to use a prism as the light guiding means.

  The pair of plane mirrors 7a and 7b are disposed above the optical axis X2. Here, as shown in FIG. 4, the lower ends of the plane mirrors 7a and 7b are arranged so as to substantially coincide with the optical axis X2 of the lens 6a. Therefore, the image of the subject on the side as viewed from the vehicle 1 also passes through the lower half area of the lens 6a without passing through the plane mirror 7, and is formed on the upper area of the CCD 6b. In other words, the pair of plane mirrors 7a and 7b is generally arranged so as to cover the region of the lens 6a through which light from the sky generally passes.

  Between the plane mirrors 7a and 7b of the camera unit 5 and the lens 6a, light from the front of the vehicle reflected by the plane mirror 7a toward the CCD 6b, light from the rear of the vehicle reflected by the plane mirror 7b and toward the CCD 6b, and the plane mirror 7a. , 7b, a partition member 12 for separating the light from the vehicle side toward the CCD 6b so as not to interfere with each other is disposed. The partition member 12 is formed of a non-translucent resin, and has a vertical partitioning portion 12a in a vertical posture joined to the vicinity of a vertical boundary line between the plane mirrors 7a and 7b, and lower ends and vertical partitions of the plane mirrors 7a and 7b. The horizontal partitioning part 12b of the horizontal attitude | position joined between the lower ends of the part 12a is included.

  As shown in FIG. 4, the image processing unit 11 provided in the control unit 10 of the vehicle 1 includes a primary captured image Ia in front of the CCD 6b captured from the image captured by the CCD 6b and the other captured by the CCD 6b. The primary captured image Ib captured by the CCD 6b through the plane mirror 7b and the lateral primary captured image Ic captured without passing through the plane mirror 7 are identified, and the primary captured image obtained through the plane mirrors 7a and 7b. Ia and Ib are reversed left and right to be converted into display images Ea and Eb having right and left positional relationships. The primary captured image Ic obtained without passing through the plane mirror 7 is displayed on the liquid crystal monitor 8 as the display image Ec without being horizontally reversed. For this purpose, as shown in FIG. 5, the image processing unit 11 includes an “inversion processing unit” for inverting the left and right of the captured image obtained through the plane mirrors 7 a and 7 b.

  The image processing unit 11 also includes two straight lines that virtually indicate the boundaries between the display images Ea, Eb, and Ec based on the captured images of the end surfaces of the vertical partition 12a and the horizontal partition 12b on the lens 6a side. The marker 20 is formed and displayed on the liquid crystal monitor 8 together with the display images Ea, Eb, and Ec. The marker 20 includes a vertical marker 20a extending vertically and a horizontal marker 20b extending horizontally. For this purpose, the image processing unit 11 detects a “partition detection unit” that detects end surfaces of the vertical partition 12a and the horizontal partition 12b on the lens 6a side from the captured image, and the detected vertical partition 12a and the horizontal partition. A “marker creation unit” that creates the markers 20a and 20b based on the unit 12b and a “composite processing unit” that synthesizes the display images Ea, Eb, and Ec and the created markers 20a and 20b are provided.

  Existing software can be used as a program for recognizing each captured image and creating an image. Prior to the image creation by the image processing unit 11, the outer surface of the translucent cover 2a is preliminarily stored in order for the control unit 10 to store the exact position of the end face of each partition 12a, 12b on the lens 6a side. An operation of recognizing only the end faces of the partition portions 12a and 12b is performed by causing the camera unit 5 to capture an image in a state of being covered with a monochromatic fabric such as blue. In addition, the markers 20a and 20b may have a linear shape that is relatively rare in the natural world and artifacts and has a clear color and is wider than the actual captured images of the partitions 12a and 12b.

  Three display images Ea, Eb, and Ec are simultaneously displayed in real time on the liquid crystal monitor 8. That is, the display image Ea in front of the vehicle obtained through the plane mirror 7a is in the left half of the upper half of the liquid crystal monitor 8, and the display image Eb in the rear of the vehicle obtained through the plane mirror 7b is in the upper half of the liquid crystal monitor 8. The vehicle-side display image Ec obtained without passing through the plane mirror 7 is displayed in the lower half area of the liquid crystal monitor 8 in the right area. The liquid crystal monitor 8 is of a touch panel type, and when the switch of the liquid crystal monitor 8 is simply turned on, three display images Ea, Eb, Ec are displayed simultaneously, but the display images Ea, Eb, When one of Ec is touched, only the selected display image is displayed on the entire surface of the liquid crystal monitor 8, and after a predetermined time has elapsed, the state returns to the three-screen state. Further, the area ratio between the display images Ea, Eb, and Ec can be freely changed by touching the markers 20a and 20b and dragging the markers 20a and 20b by dragging them vertically or horizontally on the screen. For this purpose, the control unit 10 detects the touch state of the liquid crystal monitor 8 by the driver, and moves the markers 20a and 20b in accordance with the movement of the pressure point by the pressure point detection unit. A marker moving unit "is provided.

  The control unit 10 drives either one of the camera units 5R and 5L based on a driving operation such as a steering wheel steering operation or a direction indicator operation by the driver, and the captured image is displayed on the camera liquid crystal. “Camera selection means” for displaying on the monitor 8 is provided. For example, when the turn indicator is turned to the right, this is detected by the camera selection means, the right camera unit 5R is driven, and the captured image is displayed on the camera liquid crystal monitor 8.

  Further, in a situation where the ambient light is particularly low, such as at night or in a parking lot where lighting is not sufficient, the camera unit 5 can image a subject around the vehicle based on the light emitted from the blinking lamp 9 of the direction indicator lamp 2. In this case, the control unit 10 causes the liquid crystal monitor 8 to display only an image captured while the blinking blinking lamp 9 is lit. While the blinking lamp 9 is turned off, the last image frame of the image captured during lighting is continuously displayed as a still image so that the liquid crystal monitor 8 does not display a completely dark display screen. It should be noted that if the amount of light is insufficient even while the flashing lamp 9 is lit, the control unit 10 may automatically change the setting of the shooting conditions, such as decreasing the aperture value of the video camera 6 or increasing the shutter speed.

[Another embodiment]
<1> When the camera unit 5 captures an image of a subject around the vehicle based on the light emitted from the blinking lamp 9 of the direction indicator lamp 2, the controller 10 stores the shape of the image portion obtained by imaging the vehicle 1 itself. In addition, by providing a filter processing unit that converts the captured image of the vehicle 1 itself into a color tone different from the emission color of the direction indicator lamp 2, the liquid crystal monitor 8 has a bumper of the vehicle 1 captured by the camera unit 5, for example. Since it is illuminated by the blinking lamp 9, it can be displayed in a magenta color that is completely different from the image of the subject around the vehicle that is yellowish, and the identification of the subject around the vehicle in a parking lot or the like can be improved. .

<2> A configuration in which only the picked-up images when the blinking lamp 9 of the direction indicator lamp 2 is off is continuously displayed on the liquid crystal monitor 8 regardless of whether it is daytime or nighttime is also possible. In this case, in a situation where the ambient light is particularly low, for example, a subject around the vehicle can be imaged by the camera unit 5 based on the light emitted from the vehicle width lamp. Only the captured images when the blinking lamp 9 is turned off are continuously displayed. When the blinking lamp 9 is turned on, the last image frame of the image taken while the blinking lamp 9 is turned off is continuously used as a still image. Display. Therefore, the light of the direction indicator lamp 2 directly enters the lens of the camera unit 5 and the glare is displayed on the liquid crystal monitor 8 or the light of the direction indicator lamp 2 is reflected by a part of the camera unit 5. Monitor screens with clearer images, avoiding unpleasant phenomena such as flare overlapping with the original captured image or displaying a yellowish unnatural image due to the special emission color of the flashing lamp 9 Can be displayed.

<3> In a situation where the ambient light is particularly low, when imaging a subject that is raised by light emitted from the flashing lamp 9 of the direction indicator lamp 2, or regardless of whether the flashing lamp 9 is on or off, An image may be taken and displayed on the liquid crystal monitor 8. In this case, the control unit 10 synchronizes the aperture value or shutter speed of the video camera 6 in a form synchronized with the drive signal that causes the blinking lamp 9 to blink. If the configuration is changed and set, such as weakening, it is possible to suppress a problem in which the state of the image displayed on the liquid crystal monitor 8 changes excessively, such as a significant change in brightness according to the blinking of the blinking lamp 9.

<4> The partition members 12a and 12b are formed of a transparent material colored with a fluorescent pigment or the like, and a clear image formed by imaging the end face of the partition member is processed without image processing. It may be displayed as it is. Further, in order to capture the end surface of the partition member on the lens 6a side as a clearer image, light such as an LED may be projected from the other end surfaces of the partition members 12a and 12b.

<5> It is possible to increase the size of the partition members 12a and 12b so that the light emitted from the flashing lamp 9 is prevented from directly entering the CCD 6b.

<6> The installation location of the camera units 5R and 5L is not limited to the inside of the cover 2a of the direction indicator lamp 2. For example, a vehicle having a large light-transmitting cover that simultaneously covers the headlight and the direction indicator lamp is used. In some cases, it can be placed anywhere behind this large cover.

  The present invention includes an in-vehicle camera 5 that can image a peripheral area of a vehicle, and a monitor screen that displays an image captured by the in-vehicle camera to a driver, and a plurality of areas that are different from each other by a single camera. Can be used as a vehicle driving support device capable of simultaneously monitoring
