Abstract
A camera parameter set calculation apparatus calculates three-dimensional coordinate sets corresponding to overlapping regions including images of a portion of a subject, based on a first and second images captured by a first and second cameras, a first camera parameter set of the first camera and a second camera parameter set of the second camera; determines first pixel coordinate pairs based on the first camera parameter set by projecting the three-dimensional coordinate sets on the first image; determines second pixel coordinate pairs based on the second camera parameter set by projecting the three-dimensional coordinate sets on the second image; calculates an evaluation value, based on pixel values at the first pixel coordinate pairs on the first image and pixel values at the second pixel coordinate pairs on the second image; and updates the first and second camera parameter sets based on the evaluation value.
