Method and apparatus for providing panoramic view with geometric correction
First Claim
1. A method of providing a panoramic view, the method comprising:
- receiving a source image with respect to a plurality of pixels taken with a camera, and a location vector of each of the plurality of pixels;
generating a transformation matrix for tilting the source image based on a distortion angle towards a plane direction of the source image, a distortion angle towards a depth direction of the source image, a camera parameter matrix and a location correction matrix; and
geometrically tilting the source image by obtaining a tilting vector with respect to the location vector from the transformation matrix and relocating the pixels of the source image to the tilting vector.

Abstract
A method and apparatus of correcting geometric information and providing a panoramic view. In the method of providing a panoramic view, a tilting vector (X′, Y′) is generated by applying matrices H(a,b) and HF to a source image vector (X,Y). The matrix H(a,b) is defined by distortion angles “b” towards a plane direction and a distortion angle “a” towards a depth direction of the source image, and the matrix HF is defined according to a camera parameter matrix K. Also, a two-dimensional vector (x,y) of a source image is converted into a three-dimensional vector (X,Y,W) on a retinal image plane having a unit radial distance from an origin of a ground plane. Also, a warped image width (WIW) is estimated from a width and a field of view (FOV) of the source image. A warping vector (x′,y′) is generated based on the converted vector (X,Y,W) and the WIW.
