Abstract:
A camera parameter set calculation method includes acquiring a first image from a first camera, a second image from a second camera, first and second camera parameter sets of the first camera and the second camera, calculating three-dimensional coordinate sets on the basis of the first image, the second image, the first camera parameter set, and the second camera parameter set, determining first pixel coordinate pairs obtained by projecting the three-dimensional coordinate sets onto the first image and second pixel coordinate pairs obtained by projecting the three-dimensional coordinate sets onto the second image, calculating an evaluation value on the basis of the pixel values at the first pixel coordinate pairs and the pixel values at the second pixel coordinate pairs, and updating the first camera parameter set and the second camera parameter set on a basis of the evaluation value.

Claim (Index 12):
A camera parameter set calculation apparatus comprising a processing circuit that performs the following operations:\n (a1) acquiring a first image captured by a first camera and a second image captured by a second camera; (a2) acquiring a first camera parameter set including one or more camera parameters of the first camera and a second camera parameter set including one or more camera parameters of the second camera; (a3) calculating three-dimensional coordinate sets on an object on a basis of the first image; the second image; the first camera parameter set; and the second camera parameter set, the first image including an image of the object, the second image including an image of the object; (a4) determining first pixel coordinate pairs obtained by projecting the three-dimensional coordinate sets onto the first image on a basis of the first camera parameter set and determining second pixel coordinate pairs obtained by projecting the three-dimensional coordinate sets onto the second image on a basis of the second camera parameter set; (a5) calculating an evaluation value on a basis of pixel values at the first pixel coordinate pairs in the first image and pixel values at the second pixel coordinate pairs in the second image; (a6) updating the first camera parameter set and the second camera parameter set on a basis of the evaluation value; and (a7) outputting the updated first camera parameter set and second camera parameter set.
