Problems solved by technology

[0005] However, the above-mentioned device has the following problems: it cannot show the sense of distance when actually observing the mirror
[0006] In addition, there are also problems that even if the size can be displayed by the distance sense of the actual observation mirror, the position or orientation of the display is limited, or the display is only enlarged, or it is difficult to recognize the actual distance and positional relationship, etc.

example 1

[0102] Next, a modified example of the present embodiment will be described.

[0103] Since the position of the mirror display surface B is calculated at a predetermined depth, objects can be observed naturally as long as they are within a predetermined distance. However, in a scene without objects, if the predetermined distance is rather large and not calculated, it will not be displayed correctly.

[0104] In the case where the above-mentioned predetermined distance is set to infinity (infinity), since the reflection angle of the virtual mirror A reflected from the point of view E is the same as the angle observed from the camera outside the vehicle 2, the image from the camera outside the vehicle is displayed on the display 5. 2 Just pass through the area shown by this angle. At this time, the tilt of the display 5 may be tilted depending on the user for easy viewing by the user.

[0105] In addition, the position of the mirror display surface B can also be determined in ...

example 2

[0107] Figure 6 It is a figure explaining the modified example which marked the scale on the frame D.

[0108] Preferably, scales are displayed at predetermined intervals on the frame D displayed on the display 5 . By marking the scale, the driver who observes the image displayed on the monitor 5 can more easily grasp the sense of distance. In addition, the method of marking the scale can also be set by the driver.

example 3

[0110] Figure 7 It is a figure explaining the modified example which made the line which shows the mirror frame D thick.

[0111] It is preferable to set the thickness of the line displaying the frame D to be constant, so that the inclination direction of the frame D can be easily understood by displaying the thickness of the frame. In addition, the lengths of the long sides and short sides of the mirror frame D may be individually changed.

[0112] According to this modified example, the inclination of the mirror can be known from the image of the mirror frame D. FIG.

[0113] (Modification 4 of this embodiment)

[0114] Figure 8 (a) and (b) are diagrams explaining that the lens frame D is curved and displayed. Such as Figure 8 As shown, it is also preferable to display the mirror frame D curved in a concave or convex manner. In this case, it is also possible to set the degree of curvature so that it can be changed. Also, if a plurality of frames D are prepared and ...

Abstract

Embodiments of the present invention relate to a surrounding area monitoring device for a vehicle. The technical problem to be solved by the present invention is to provide a peripheral monitoring device for a vehicle that enables a driver to easily recognize the sense of distance, positional relationship, and direction of a displayed image. Including: the camera outside the vehicle, which shoots the surrounding area of ​​the vehicle; the display, which displays the image; and the image processing unit, which obtains the position information of the driver's viewpoint, the position information of the display, and geometrically converts the image captured by the camera outside the vehicle into The position information of the virtual mirror of the image observed from the viewpoint, and based on the position information of the viewpoint, the position information of the display, the position information of the virtual mirror and the image of the camera outside the car, create a mirror display displayed on the virtual mirror observed from the viewpoint For the image, the image processing unit creates a mirror frame surrounding the mirror display image, and displays the mirror frame and the mirror display image inside the mirror frame on the display.

Description

[0001] This application is based on and claims the benefit of priority of Japanese Patent Application No. 2016-075033 filed on April 4, 2016, the entire contents of which are hereby incorporated by reference. technical field [0002] Embodiments of the present invention relate to a peripheral monitoring device for a vehicle. Background technique [0003] There is known a device that uses a camera to photograph the periphery of a vehicle instead of a rearview mirror of the vehicle and presents the captured image to the driver. [0004] For example, a device in which a camera is installed on an extension line between a driver's viewpoint and a display, and a vehicle surrounding monitoring system in which a display range is changed according to the position of the driver's head have been proposed. Also proposed are vehicle display devices that correct the size and position of the display so that the size of the displayed content is visible in a mirror, or display systems that c...
