BRIEF DESCRIPTION OF THE DRAWINGS The above and other objects, features and advantages of the present invention will become more apparent from the following detailed description when read in conjunction with the accompanying drawings, in which: FIG.

1 is a system block diagram of a vehicle side mirror camera according to the present invention.

1, the system of a vehicle side mirror camera according to the present invention includes a side mirror camera 10, a control unit 11, a display device 15, a power supply unit 16, a memory unit 17, (18).

The side mirror camera 10 is composed of a left camera 12, a right camera 13, and a rear camera 14.

The left camera 12, the right camera 13 and the rear camera 14 are constituted by a wide angle camera having a 180 degree angle of view, and a 180 degree angle of view camera is a very important factor in the implementation of the present invention, This is to eliminate blind spots when shooting.

The left camera 12 is attached to the left side of the vehicle so that the left front side is photographed and displayed on the display device 15 inside the vehicle. The right side camera 13 is attached to the right side of the vehicle, And the rear camera 14 photographs the rear side of the vehicle and displays it on the display device 15 inside the vehicle.

The left camera 12, the right camera 13, and the rear camera 14 can replace the existing side mirrors and the room mirrors of the vehicle, thereby eliminating the side mirrors and the room mirrors of the vehicle.

The control unit 11 controls the display unit 15 to display the photographed images of the camera and controls the display unit 15 to display the sensed signals of the distance sensing unit 18 in corresponding areas. Further, the photographed image can be stored in the memory unit 17, the program stored in the memory unit 17 can be called up and executed, and power can be supplied to the camera.

The display device 15 may be a monitor such as an LCD, and may be a separate device, a navigation device, or a display device of a black box. In addition, the display device 15 may be constituted of a plurality of screens, and may be configured to display each camera video signal by dividing a plurality of screens into one display device.

The distance sensing unit 18 can be mounted on the rear side and the left and right rear sides of the vehicle and serves to sense the distance to the rear and left and right nearest vehicles of the vehicle.

The camera device of the present invention replaces the side mirror and is mainly used during traveling. Therefore, while the vehicle (or obstacles, ridges, etc.) on the rear side and the left and right sides are displayed on the display device 15 during driving, it is difficult to precisely confirm the distance between the displayed adjacent vehicle and the vehicle itself.

In addition, it is practically meaningless to detect and display the distance between the own vehicle and the adjacent vehicles that are running. In other words, even though the speed of your vehicle and the speed of different incoming vehicles on the highway (60-80km / hr) or the highway (100km / hr) Or less), so the display itself is meaningless.

Accordingly, in the present invention, the distance sensing unit 18 senses and displays an object when approaching within a predetermined distance, and senses the distance to the object closest to the own vehicle.

For example, when a vehicle on the left side (or right side or rear side) is in the middle of driving the vehicle, the distance between the vehicle and the proximity vehicle is within 1 m So that the signal can be confirmed to the driver through the display device 15.

2 shows a camera mounting structure and an imaging range of a side mirror camera for a vehicle according to the present invention.

2, the side mirror camera 10 is constituted by a left camera 12, a right camera 13 and a rear camera 14, and the left camera 12 comprises a left camera 12, And the right camera 13 is attached to the right side of the vehicle 21 and the rear camera 14 is attached to the rear side of the vehicle 21. [

The camera is a camera having an angle of view of 180 degrees. As shown in the figure, the entire 180 degrees area 22, 23, 24 in the photographing direction is photographed according to the attached position.

That is, the left front side 180 degree region 22 is photographed by the left camera 12, the right side front side 180 degree region 23 is photographed by the right side camera 13, The 180 degree area 24 is photographed.

In the left and right rear portions, there is a portion where the front 180 degree region 22 on the left side overlaps with the rear 180 degree region 24 and a portion where the right front 180 degree region 23 and the rear 180 degree region 24 overlap . This means that there are no blind spots that can not be photographed by three 180 degree angle camera.

The above-described camera apparatus of the present invention will be further subdivided by each area.

The area where the adjacent vehicle (or building or the like) can be located on the basis of the vehicle 21 is limited to seven positions P1 to P7.

The first position P1 is the left front position based on the driver of the vehicle 21, the second position P2 is the first left rear position with respect to the driver, and the third position P3 is the second The fourth position P4 is a rear position with respect to the driver, the fifth position P5 is a right front position with respect to the driver, the sixth position P6 is a first right rear position with respect to the driver, The position P7 means the second right rear position with respect to the driver.

Here, the first left rear position P2 and the second left rear position P3 are those in which the second left rear position P3 is located further rearward than the first left rear position P2, The first left rear position P2 is an area photographed only by the left camera 12 and the second left rear position P3 is an area which is simultaneously photographed by the left camera 12 and the rear camera 14. [ Similarly, the first and second right rear positions P6 and P7 have the same concept.

Here, both the left front position P1 and the first left rear position P2 are the same as the imaging area by the left camera 12, but in the case of the left front position P1, they are displayed on the display device 15, In the case of the first left rear position P2, only the display device 15 is displayed.

Therefore, the driver can easily know the position of the adjacent vehicle on the screen displayed on the display device 15, and there is no dead zone based on the vehicle.

3 is a structural view for confirming a minimum distance between a mounting position of a distance sensing unit and a nearest adjacent vehicle in a vehicle side mirror camera according to the present invention.
