PROBLEM TO BE SOLVED: To provide a method and an apparatus for providing a panoramic view with geometric correction. SOLUTION: A tilting vector is generated by applying matrices H(a, b) and HF to a source image vector (x, y), the matrix H(a, b) being defined by distortion angles "a" towards a plane direction and a distortion angle "b" towards a depth direction, and the matrix HF being 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). The number of pixels corresponding to a certain angle in the width direction of the retinal image plane is projected on a cylinder. A warping vector is generated based on the converted vector (X, Y, W) and the warped image width (WIW). COPYRIGHT: (C)2007,JPO&INPIT |
