Abstract
A method, apparatus, system, article of manufacture, and computer readable storage medium provides the ability to determine two or more camera viewpoint optical centers. A first image and a second image captured by camera devices (and the rotations for the camera devices) are obtained. For each pair of matched points between the first image and the second image, a linear equation is defined that utilizes the rotations, pixel coordinates of the matched points and optical centers. A matrix ATA is computed where each row of A corresponds to a pair of matched points and the number of columns is 3N (N representing the number of camera devices). The matrix is solved resulting in an eigenvector that holds the optical centers that are used to output image information.
