Method and apparatus for creating 3D image of vehicle surroundings
First Claim
1. A method for creating a 3D image of vehicle surroundings, the method comprising:
- mapping images captured by a plurality of cameras installed in a vehicle to a virtual plane defined by a 3D space model of a vessel shape which has a flat bottom surface and a radius increasing toward a top; and
creating a view image of a viewpoint of a virtual camera by using the images mapped to the virtual plane,wherein a size of the bottom surface of the 3D space model is in inverse proportion to a driving speed of the vehicle.

Abstract
The present invention relates to a method and apparatus for creating a 3D image of vehicle surroundings. The method according to the present invention includes the steps of: mapping images captured by a plurality of cameras installed in a vehicle to a virtual plane defined by a 3-dimensional space model having a container shape with a flat bottom surface and a top surface which has an increasing radius; and creating a view image having a viewpoint of a virtual camera by using the image mapped to the virtual plane. According to the present invention, it is advantageous that an image of vehicle surroundings including surrounding obstacles can be expressed naturally and three-dimensionally. It is also advantageous that an optimal image of vehicle surroundings can be provided by changing the virtual viewpoint according to a traveling state of the vehicle. There is also the advantage that a user can conveniently adjust the viewpoint of the virtual camera.
