Multi-camera driver assistance system
Disclosed herein is a multi-camera driver assistance system. The system includes a plurality of cameras which dispose at different positions of a vehicle to capture images of a vicinity of the vehicle; an image processing unit which generates a virtual view with respect to a predetermined projection surface based on the images; and a display device which displays the virtual view, wherein the predetermined projection surface includes a slanted projection surfaces which are located at lateral sides of the vehicle.
1. A multi-camera driver assistance system, comprising:
a plurality of cameras which are disposed at different positions of a vehicle to capture images of a vicinity of the vehicle;
an image processing unit which generates a virtual view with respect to a predetermined projection surface based on the images; and
a display device which displays the virtual view,
wherein the predetermined projection surface includes a flat projection surface having a predetermined distance around the vehicle and slanted flat projection surfaces, which are not curved and are located at lateral sides of the vehicle, and vertical projection surfaces which are located in front and behind the vehicle and approximately perpendicular to the ground, and
wherein the processing unit is configured to increase the predetermined distance of the flat projection surface and angles of the slanted flat projection surface from the ground in response to a virtual view expanding command, or to decrease the predetermined distance of the flat projection surface and angles of the slanted flat projection surface from the ground in response to a virtual view contracting command.
2. The system of claim 1 , wherein the image processing unit is an electronic control unit (ECU) in the vehicle.
3. The system of claim 2 ,
wherein the slanted flat projection surface is connected to the flat projection surface.
4. The system of claim 1 , wherein the image processing unit is configured to receive the virtual view expanding command which is inputted from a user.
5. The system of claim 1 , wherein the image processing unit is configured to receive the virtual view contracting command which is inputted from a user.
6. A method of displaying a virtual image by a multi-camera driver assistance system, the method comprising:
receiving a plurality of captured images of a vicinity of a vehicle which disposes at different positions of the vehicle;
generating a virtual view with respect to a predetermined projection surface based on the images;
changing the virtual view in response to a virtual view command; and
transmitting the virtual view to a display device,
wherein the predetermined projection surface includes a flat projection surface having a predetermined distance around the vehicle and a slanted flat projection surfaces, which are not curved and are located at lateral sides of the vehicle, and vertical projection surfaces which are located in front and behind the vehicle and approximately perpendicular to the ground, and
wherein the changing the virtual view comprises increasing the predetermined distance of the flat projection surface and angles of the slanted flat projection surface from the ground in response to a virtual view expanding command, or decreasing the predetermined distance of the flat projection surface and angles of the slanted flat projection surface from the ground in response to a virtual view contracting command.
7. The method of claim 6 , wherein the generation of the virtual view is executed by an electronic control unit (ECU) in the vehicle.
8. The method of claim 7 ,
wherein the slanted flat projection surface is connected to the flat projection surface.
9. The method of claim 8 , further comprising receiving the virtual view expanding command which is inputted from a user.
10. The method of claim 8 , further comprising receiving the virtual view contracting command which is inputted from a user.
