Description

The present invention relates to a vehicle visual recognition device that photographs a vehicle peripheral area and displays a photographed image in order to visually recognize the vehicle peripheral area.

There is known a vehicle visual recognition device in which a photographing unit such as a camera and a display unit such as a monitor are mounted on a vehicle, and a photographed image taken by the photographing unit around the vehicle is displayed on the display unit.

In such a vehicle visual recognition device, when the driver is driving, he / she looks at a distance and drives, and when the viewpoint is switched to the display unit in the vehicle interior, it is necessary to refocus the eyes closer. there were. In addition, some people with presbyopia or hyperopia may not be able to focus on a nearby place, and may not be able to focus on the display part in the vehicle interior.

Therefore, it is conceivable to give the vehicle visual recognition device a configuration for adjusting the focus and diopter. For example, as a technique for adjusting diopter, the technique of Patent Document 1 has been proposed. Patent Document 1 proposes a diopter correction device that corrects diopter, such as eyeglasses and contact lenses, by converting a display image by image processing to correct out-of-focus on the viewer's retina.

Japanese Patent No. 5607473

When the technique of adjusting the diopter of the occupant by image processing is used by using the technique of Patent Document 1, if the image processing is performed on the entire area of the captured image displayed on the display unit, the processing load is high. turn into. Further, when the processing load becomes high, a delay in display occurs, which affects the visibility around the vehicle, and there is room for improvement.

The present invention has been made in consideration of the above facts, and an object of the present invention is to provide a vehicle visibility device capable of ensuring visibility around a vehicle while reducing the processing load of virtual focus adjustment. ..

In order to achieve the above object, the first aspect is to perform image processing on a display unit that displays a photographed image around the vehicle, a predetermined area of the photographed image, or an area other than the area.

In addition, when a vehicle is detected within a predetermined distance in the captured image, the display control is performed with the area corresponding to the vehicle within the predetermined distance as the predetermined area .

According to the first aspect, since the photographed image around the vehicle is displayed on the display unit, the periphery of the vehicle can be visually recognized by checking the display unit.

The control unit virtually changes the focus of the eyes to a predetermined position where the occupant can ensure visibility by performing image processing on a part of the captured image or an area other than the predetermined area. The display is controlled to be displayed on the display unit. By controlling in this way, image processing is performed on a part of the display unit without performing virtual focus adjustment on the entire surface, so that the processing load can be reduced. In addition, visibility can be ensured by securing a part that can be seen without blurring even if the focus is switched to some beat.

In addition , when a vehicle is detected within a predetermined distance in the captured image and at a speed higher than the predetermined vehicle speed, the control unit displays an area corresponding to the vehicle within the predetermined distance as a predetermined area. control intends line.

In addition, the control unit prohibits the virtual adjustment of the focal point and displays the captured image on the display unit when the vehicle speed is lower than the predetermined vehicle speed or when the vehicle is not detected within the predetermined distance in the captured image. The uncorrected display control may be performed, or the full-face corrected display control may be further performed by virtually changing the focus on the captured image corresponding to the entire surface of the display unit and displaying the image on the display unit.

Further, the control unit may further perform backward display control for displaying on the display unit by virtually changing the focus on the captured image corresponding to the entire surface of the display unit when the vehicle is detected to be retracted. ..

Further, the control unit may change the focus position to a position preset by the occupant when the focus is virtually changed.

As described above, according to the present invention, there is an effect that it is possible to provide a vehicle visibility device capable of ensuring visibility around the vehicle while reducing the processing load of virtual focus adjustment.

The vehicle visual recognition device 10 is provided with a rear camera 18 and a door camera 16 (16L, 16R). The rear camera 18 is arranged at the rear of the vehicle and at the center of the vehicle width direction (for example, the center of the trunk or the rear bumper in the vehicle width direction), and is capable of photographing the rear of the vehicle at a predetermined angle of view (shooting area). Further, the door camera 16L is provided on the door mirror on the left side of the vehicle width, and the door camera 16R is provided on the door mirror on the right side of the vehicle width. The door cameras 16L and 16R are capable of photographing the rear of the vehicle from the side of the vehicle body at a predetermined angle of view (shooting area). In the following, the door cameras 16L and 16R will be described as the door camera 16 when the left and right are not distinguished.

The rear camera 18 and the door camera 16 photograph the rear of the vehicle as the periphery of the vehicle. Specifically, a part of the shooting area of the rear camera 18 overlaps with a part of the shooting area of the door camera 16, and the rear camera 18 and the door camera 16 make the rear of the vehicle from diagonally right rear to diagonally rear left of the vehicle body. It is possible to shoot over the range of. As a result, the rear side of the vehicle is photographed at a wide angle.

An inner mirror 22 (see FIG. 3) is provided in the vehicle interior of the vehicle, and the inner mirror 22 is attached to the front side of the vehicle interior and the central portion in the vehicle width direction on the ceiling surface of the vehicle interior. The inner mirror 22 is provided with a monitor 12 having a long rectangular shape as a display unit, and the monitor 12 has a longitudinal direction in the vehicle width direction and a display surface facing the rear of the vehicle. As a result, the monitor 12 is arranged near the upper part of the front windshield glass on the front side of the vehicle, and the display surface is visible to the occupants in the vehicle interior.

A half mirror (wide mirror) is provided on the display surface of the monitor 12, and when the monitor 12 is hidden, the half mirror captures the rear view through the rear window glass and the door glass together with the vehicle interior. Will be done.

Further, an inner camera 14 is provided in the vicinity of the inner mirror 22, and the shooting direction is directed to the rear of the vehicle, and the inner camera 14 shoots the interior of the vehicle.

Further, the vehicle visual recognition device 10 is provided with a control device 20 as a control unit, and the control device 20 includes a monitor 12, an inner camera 14, a door camera 16, a rear camera 18, a vehicle speed sensor 36, and a rear monitoring unit. 38 is connected. The control device 20 includes a microcomputer in which a CPU 20A, a ROM 20B, a RAM 20C, a non-volatile storage medium (for example, EPROM) 20D, and an I / O (input / output interface) 20E are connected to the bus 20F, respectively. Various programs such as a vehicle visual display control program are stored in the ROM 20B and the like, and the CPU 20A reads and executes the program stored in the ROM 20B and the like so that the control device 20 can visually recognize the occupant on the monitor 12. Display an auxiliary image.

The vehicle speed sensor 36 detects the speed of the vehicle (hereinafter referred to as vehicle speed) and outputs the detection result to the control device 20.

The rear monitoring unit 38 monitors obstacles, vehicles, and the like behind it, and outputs the monitoring result to the control device 20. For example, various radars such as an ultrasonic radar and a laser radar may be applied to the rear monitoring unit 24, or a camera capable of measuring a distance such as a stereo camera may be applied.

Further, the control device 20 controls to generate a visual image by superimposing the images taken outside the vehicle taken by each of the rear camera 18 and the door camera 16 and display them on the monitor 12. In this embodiment, although the details will be described later, the control device 20 controls the visual recognition image to be displayed on the monitor 12 by virtually adjusting the focus of the occupant by performing image processing. The monitor 12 is provided on the front side of the vehicle from the driver's seat, and the image displayed on the monitor 12 is horizontally inverted with respect to the captured image. Further, when the visual image is generated, the captured image of the inner camera 14 may be transmitted and superimposed.

Next, the function of the control device 20 realized by executing the program stored in the ROM 20B of the control device 20 will be described. FIG. 2 is a functional block diagram showing the functions of the control device 20 of the vehicle visual recognition device 10 according to the present embodiment.

As shown in FIG. 2, the control device 20 has the functions of a visual image generation unit 30, a processing unit 32, a feature point extraction unit 40, and a virtual correction image processing unit 34 as a control unit.

The visual recognition image generation unit 30 acquires the captured images of the rear camera 18 and the door camera 16, respectively, and synthesizes the captured images to generate a visual recognition image.

The processing unit 32 performs various corrections and the like on the visual recognition image generated by the visual visual image generation unit 30 based on inputs other than image information and the like. Further, personal authentication information or the like may be input to the processing unit 32 by a key, a fingerprint or the like. When the personal authentication information is input to the processing unit 32, the personal authentication result or the focal length information corresponding to the personal authentication result is output to the virtual corrected image processing unit 34.

The feature point extraction unit 40 extracts feature points for detecting a vehicle behind from a visual image, and detects a vehicle behind from the extracted feature points. Then, the detection result of the vehicle behind is output to the virtual correction image processing unit 34.

The virtual correction image processing unit 34 performs a process of virtually changing the focus of the eyes by performing image processing for virtually correcting the visual image processed by the processing unit 32, and the monitor 12 is used. Display a visual image. In the present embodiment, the focus of the eyes is virtually changed with respect to a predetermined area of the visual image or an area other than the predetermined area.

Specifically, when the predetermined condition is satisfied, the virtual correction image processing unit 34 virtually adjusts the focus on the predetermined region or the region other than the predetermined region. As an example of the predetermined conditions, the vehicle speed sensor 36 detects the vehicle speed or higher, and the rear is predetermined based on the detection result of the vehicle behind the feature point extraction unit 40 and the monitoring result of the rear monitoring unit 38. This applies when it is detected that there is a vehicle behind within the distance. Further, as an example of the focal position when virtually adjusting the focus, the focal position is adjusted to a focal position registered in advance for each occupant or a focal position preset by the occupant. For example, when the virtual correction image processing unit 34 receives the personal authentication result from the processing unit 32, the virtual focus on the visual recognition image may be changed to a focal length registered in advance for each individual. Alternatively, when the virtual correction image processing unit 34 receives the focal length information corresponding to the personal authentication result from the processing unit 32, the virtual correction image processing unit 34 may virtually adjust the focus according to the received focal length information. .. Alternatively, the focus may be adjusted according to the instructions of the occupant by operating a switch or the like.

Further, when the virtual correction image processing unit 34 displays the visual image on the monitor 12, the mirror image conversion process is performed and the left and right sides are inverted, and the mirror image conversion process is performed by the visual image generation unit 30. It may be performed by either the processing unit 32 or the virtual corrected image processing unit 34. In the following description, the mirror image conversion may be omitted for the sake of brevity.

The virtual corrected image processing unit 34 can perform virtual focus adjustment by image processing using, for example, the diopter correction technique described in Japanese Patent No. 5607473 cited as Patent Document 1. Alternatively, Fu-Chung Huang, 3 others, "Eyeglasses-free Display", [online], [Searched on November 13, 2017], Internet (URL: http://web.media.mit.edu/~ The technique described in gordonw / VisionCorrectingDisplay /) may be used.

Here, an example of virtual correction by image processing performed by the virtual correction image processing unit 34 will be described. FIG. 3 is a diagram showing a state in which the driver is on board, and FIG. 4 is a diagram for explaining virtual correction by image processing.

As shown in FIG. 3, when the driver is looking forward, he is driving so that the focus is on the front distance d1. On the other hand, when the optical inner mirror 22 is used, the driver is operated so that the focus of the eyes is on the rear distance d2. Here, d1 and d2 are distances of 5 m or more, 100 m or more depending on the driving situation, and are farther than the distance d3 between the driver and the inner mirror 22.

The inner mirror 22 is physically located at a distance d3. When the optical inner mirror 22 is used, in order to focus on the reflected image, the person looks behind the point separated by the distance d2 at the focal length D = d2 without being conscious of the distance d3. On the other hand, when looking at the monitor 12, since it is necessary to look at the rear image reflected on the monitor 12, the focal length of the eyes is adjusted to the distance d3 to see the rear view.

As shown in FIG. 4A, when the focal length D is adjusted to the monitor 12 at the distance d3, it looks normal without blurring. On the other hand, as shown in FIG. 4B, when the focal distance D of the eyes matches the distance d1, the monitor 12 at the distance d3 looks blurred, but it is virtualized by the virtual correction image processing unit 34. By performing the correction by image processing, the virtual focal distance D for the image on the monitor 12 located at the distance d3 is set to the distance d1 so that the image can be clearly seen. That is, the image (rear view) of the monitor 12 can be viewed without returning the focal length D from the distance d1 to the distance d3. The distance d1 is set to a distance of 5 m or more in front, but when the distance d1 (however, d1> d3) is set to the shortest distance that a person with presbyopia (hyperopia) can see, it cannot be seen as an eye ability. You can also see the image of the monitor 12 at the distance d3 which is a part.

By the way, the virtual correction image processing unit 34 is capable of virtually adjusting the focus by image processing in order to make it easier for the occupant to see the image displayed on the monitor 12, but it is virtual for the entire screen of the monitor 12. If the focus is adjusted, the processing load will increase. Further, if the focus is changed to the distance d3 or the like due to some beat, it may appear blurred and the visibility may be deteriorated.

Therefore, in the present embodiment, as described above, the virtual correction image processing unit 34 performs image processing on a predetermined region or an region other than the region, virtually adjusts the focus, and displays the image on the monitor 12. Display control is performed. In the following, an example of virtually adjusting the focus on a predetermined area will be described.

Specifically, when a predetermined condition is satisfied (in the present embodiment, when a vehicle behind the vehicle exists within a predetermined distance when traveling at a vehicle speed higher than the predetermined vehicle speed), the dotted line in FIG. 5 (A) is used. As shown in the area shown, the appearance is virtually corrected only for vehicles near the rear. By doing so, visibility can be ensured by securing a portion that can be seen without blurring even if the focal point is at a distance d3. In addition, it is possible to make it easier to see the necessary part by setting the area that can be seen without blurring to the area of the vehicle behind the vehicle to be watched. Further, since image processing is performed on a part of the monitor 12 without performing virtual focus adjustment on the entire surface, the processing load can be reduced.

Here, the condition for virtually correcting is limited to the case where there is a vehicle in a position close to the rear, if there is no element (vehicle) to be noted in the rear, there is no problem in safety even if it is slightly blurred. Because. In addition, the condition for virtual correction is limited to when driving at a vehicle speed higher than the predetermined speed, in the case of slow retreat such as when entering the garage, the entire surface is virtually corrected without processing a part of the image. This is because it is less likely to cause confusion.

The virtual correction image processing unit 34 controls the uncorrected display when the predetermined conditions are not satisfied (in the present embodiment, when the vehicle speed is less than the predetermined vehicle speed or the rear vehicle does not exist within the predetermined distance). Alternatively, full-scale correction display control is performed. The uncorrected display control is a control that prohibits virtual focus adjustment and displays a visual image on the monitor 12. On the other hand, the full-face correction display control is a control in which the focus is virtually changed on the visual image corresponding to the entire surface of the monitor 12 and displayed on the monitor 12.

Further, the region shown by the dotted line in FIG. 5 (A) may be a region wider than that in FIG. 5 (A), including a vehicle at a location close to the rear, such as the region shown by the dotted line in FIG. 5 (B).

Further, in the virtual focus adjustment by the virtual correction image processing unit 34, for example, while the vehicle starting operation is being performed, the change of the focus of the eyes is virtually started, and when the vehicle starting operation is completed, the virtual focus adjustment is performed. You may finish changing the focus. That is, while the vehicle starting operation is being performed, the focus is virtually changed with respect to the image displayed on the monitor 12, and the focus is determined when the vehicle starting operation is completed. As a result, the focus of the occupant can be easily set by ending the starting operation of the vehicle when the occupant's eyes are in focus.

Subsequently, a specific process performed by the control device 20 of the vehicle visual recognition device 10 according to the present embodiment configured as described above will be described. FIG. 6 is a flowchart showing an example of the flow of processing performed by the control device 20 of the vehicle visual recognition device 10 according to the present embodiment. The process of FIG. 7 starts when an ignition switch (IG) (not shown) is turned on. Alternatively, it may be started when an instruction to turn on the power of the monitor 12 is given.

In step 100, the CPU 20A starts acquiring the captured image of the camera and proceeds to step 102. That is, the visual recognition image generation unit 30 acquires the captured images captured by each of the rear camera 18 and the door camera 16 and synthesizes the captured images to generate a visual visual image.

In step 102, the CPU 20A displays a rear view image on the monitor 12 and proceeds to step 104. That is, the visual image generated by the visual image generation unit 30 and subjected to various corrections by the processing unit 32 is displayed on the monitor 12 via the virtual corrected image processing unit 34. At this time, the virtual correction image processing unit 34 performs image processing on the visual image to virtually adjust the focus and display it on the monitor 12, but the focus position is set to a position predetermined by the occupant. It will be adjusted. For example, as described above, while the vehicle is being started.

When the focus is virtually adjusted, the occupant gets on the vehicle and adjusts to the adjustment value adjusted by operating a switch when the vehicle is started. Alternatively, when the processing unit 32 receives the personal authentication result by a key, a fingerprint, or the like, it may be adjusted to the adjustment value of the occupant registered in advance.

In step 104, the CPU 20A detects the vehicle speed and proceeds to step 106. That is, the detection result of the vehicle speed sensor 36 is acquired.

In step 106, it is determined whether or not the CPU 20A is equal to or higher than a predetermined vehicle speed. In the determination, the virtual correction image processing unit 34 determines whether or not a vehicle speed higher than a predetermined vehicle speed is detected from the detection result of the vehicle speed sensor 36. If the determination is affirmed, the process proceeds to step 108, and if the determination is negative, the process proceeds to step 116.

In step 108, the CPU 20A extracts feature points from the captured image and proceeds to step 110. That is, the feature point extraction unit 40 extracts the feature points in the visual recognition image in order to detect the vehicle behind, detects the vehicle behind from the extracted feature points, and obtains the detection result as the virtual correction image processing unit 34. Output to.

In step 110, the CPU 20A determines whether or not there is a vehicle within a predetermined distance. In the determination, the virtual correction image processing unit 34 determines whether or not the vehicle exists within a predetermined distance behind based on the detection result of the vehicle behind the feature point extraction unit 40 and the monitoring result of the rear monitoring unit 38. judge. If the determination is affirmed, the process proceeds to step 112, and if the determination is negative, the process proceeds to step 116.

In step 112, the CPU 20A corrects a part of the rear view image, displays it on the monitor 12, and proceeds to step 114. That is, the virtual correction image processing unit 34 is in the area of the vehicle (for example, the dotted line area of FIGS. On the other hand, the appearance is virtually corrected. By doing so, visibility can be ensured by securing a portion that can be seen without blurring even if the focal point is at a distance d3. In addition, it is possible to make it easier to see the necessary part by setting the area that can be seen without blurring to the area of the vehicle behind the vehicle to be watched. Further, since the image processing is performed on a part of the monitor 12 without performing the image processing on the entire surface, the processing load can be reduced.

On the other hand, in step 116, the CPU 20A determines whether or not a part of the rearward visual recognition image is being corrected. In the determination, it is determined whether or not the virtual correction image processing unit 34 has already executed step 112 to virtually correct a part of the visual image. If the determination is affirmed, the process proceeds to step 118, and if the determination is negative, the process proceeds to step 114.

In step 118, the CPU 20A stops some corrections in the rearward visual image and shifts to step 114. That is, the virtual correction image processing unit 34 stops the virtual correction performed on a part of the rearward visual recognition image, and proceeds to step 114. When a part of the correction in the rearward visual recognition image is stopped, the virtual correction may be prohibited by the uncorrected display control and the uncorrected visual recognition image may be displayed on the monitor 12. Alternatively, a visual image corrected for the entire surface of the monitor 12 may be displayed on the monitor 12 by stopping a part of the correction by the full-face correction display control.

In step 114, the CPU 20A determines whether or not the ignition switch (IG) has been turned off. If the determination is denied, the process returns to step 104 and the above processing is repeated, and if the determination is affirmed, a series of processing is terminated. The process of step 114 may determine whether or not an instruction to turn off the power of the monitor 12 has been given.

In this way, as described above, the virtual correction image processing unit 34 performs image processing on the predetermined area and virtually adjusts the focus on the predetermined area, so that the focus of the occupant is adjusted. Visibility can be ensured by securing a part that can be seen without blurring even if it is switched. Further, since the image processing is performed on a part of the monitor 12 without performing the image processing on the entire surface, the processing load can be reduced.

If a retreat is detected by a shift sensor or the like during the process of FIG. 6, the system may shift to the retreat display control for displaying the corrected visual image on the entire surface of the monitor 12. For example, when a retreat is detected, the retreat display control process of FIG. 7 is performed as an interrupt process. FIG. 7 is a flowchart showing an example of the flow of interrupt processing (backward display control) at the time of reverse movement performed by the control device 20 of the vehicle visual recognition device 10 according to the present embodiment. Further, the process of FIG. 7 shall be started when a backward movement is detected by a shift sensor or the like.

In step 200, the CPU 20A corrects the entire surface of the rear view image and shifts to the display step 202 on the monitor 12. That is, the virtual correction image processing unit 34 virtually corrects the appearance of the entire surface of the rearward visual recognition image. This makes it easier to see the entire surface of the visual image when slowly retreating, such as when entering the garage, and is less likely to cause confusion.

In step 202, the CPU 20A determines whether or not the retreat is complete. The determination determines whether or not a shift sensor or the like has detected something other than backward movement. It waits until the determination is affirmed and proceeds to step 204.

In step 208, the CPU 20A returns to the state before correcting the entire surface of the rear view image, ends the interrupt process, and returns to the process before the interrupt process.

In this way, by performing the interrupt processing, it is possible to perform virtual correction on the entire surface of the visual recognition image in conjunction with the retreat, and it is possible to make the entire surface of the visual recognition image easy to see at the time of retreat.

In the above embodiment, an example of virtually adjusting the focus on the area of the vehicle behind or the area other than the area detected by the feature point extraction unit 40 has been described, but the present invention is not limited to this. .. For example, the focus may be virtually adjusted to a predetermined region such as the central portion of the visual recognition image or a region other than the region without providing the feature point extraction unit 40. Further, the occupant may specify the area for virtually adjusting the focus.

Further, in the above embodiment, an example in which the captured images of the plurality of cameras (rear camera 18 and door camera 16) are combined and displayed on the monitor 12 will be described, but the present invention is not limited to this. The image captured by a single camera (for example, the rear camera 18) may be displayed on the monitor 12.

Further, the processing performed by the control device 20 in the above embodiment has been described as software processing, but the processing is not limited to this. For example, it may be a process performed by hardware, or it may be a process in which both hardware and software are combined.

Further, the processing performed by the control device 20 in the above embodiment may be stored in a storage medium as a program and distributed.

Further, the present invention is not limited to the above, and it is needless to say that the present invention can be variously modified and implemented within a range not deviating from the gist thereof.
