Description

Vehicle image processing apparatus and method thereof {APPARATUS AND METHOD FOR PROCESSING IMAGE OF VEHICLE}

The present invention relates to an image processing apparatus for a vehicle and a method thereof. More specifically, the driver lights up the left and right direction indicators of the vehicle and simultaneously displays an image of the surroundings of the vehicle photographed by the camera through the navigation. The present invention relates to a vehicle image processing apparatus and a method for identifying a blind spot of a vehicle.

Recently, various safety equipments for safe driving as well as performance improvement of a vehicle have been installed in a vehicle, and an example thereof includes an ultrasonic sensor or a rear camera.

On the side of the vehicle is a mirror (hereinafter referred to as "side mirror") that allows you to check the situation of the rear and rear, and there are four blind spots that cannot be seen with this side mirror. Due to a lot of accidents, the driver checks again using a mirror mounted on the inside of the vehicle (hereinafter referred to as a "room mirror"), or even by turning his head.

However, the rear region identified by the room mirror is also limited. In particular, the rear area on the driver's side is more difficult to identify. In order to solve the problem caused by the blind spot, a technique for mounting a camera inside the side mirror and displaying an image taken from the camera for navigation or the like has been proposed. In addition, a technique for displaying an image transmitted from a camera on a room mirror has been proposed.

When the driver secures the view through the provided side mirror of the vehicle and enters to the left or right side of the vehicle, when the driver has a blind spot, there is a high possibility of an accident, and when the driver turns on the left or right turn indicator, the vehicle provides the vehicle. The 12V power supply ON / OFF is repeatedly supplied, there is a problem that the navigation image is interrupted as the 12V power supplied to the camera is turned ON / OFF.

In order to improve the problems described above, the technology for displaying the blind spot of the vehicle through the navigation for safe operation is being researched and developed in various industries and academia, Korean Patent Publication No. 10-2009-0060973 (for vehicles Camera apparatus).

1, the camera 30 is mounted to look in the same direction as the observation surface of the side mirror 20, and forms a hole 21 in a portion of the side mirror 20.

Through the configuration of the prior document as described above, the camera is mounted to look at the same direction as the reflection surface of the side mirror, and the hole of the camera is directly connected to the outside through the hole, so that the lens of the camera directly communicates with the outside through the hole. It is possible to reduce the blind spots of the vehicle by increasing the shooting range by installing the camera outside the center line of the side mirror, that is, away from the driver.

However, since these cameras are installed separately regardless of the operation conditions of the vehicle, for example, the direction indicator lever operation, the gear lever operation, etc., wiring becomes complicated to process images transmitted from the left and right cameras. In addition, an additional control module for dividing or controlling an image transmitted through navigation or the like is additionally required.

In this way, as the camera is operated separately from the operation situation of the vehicle, the device configuration becomes complicated, and as the hole must be drilled directly into the side mirror, the work process is cumbersome and it is not easy to install in the vehicle, and the installation cost increases.

First, when the driver operates the direction indicator lever to change to the left lane while driving the vehicle, the first relay R1 is switched ON while the left blinking signal is turned on (S10a).

Subsequently, when the first relay R1 is switched ON, the first relay a contact R1-a is switched ON so that the left camera 110 is driven (S20a).

Subsequently, when the lane change is completed and the driver returns the turn indicator lever to the original position, the first relay R1 is switched to OFF (S30a).

Then, the first relay a contact (R1-a) is switched off (OFF), the driving of the left camera 110 is stopped (S40a).

Subsequently, while the high level lighting signal is input, power is supplied to the left camera through the sixth relay R6 (S600).
