A camera parameter set calculation method including (a1) acquiring a first image captured by a first camera and a second image captured by a second camera, (a2) acquiring camera parameter sets of the first and second cameras, (a3) extracting, from the first image, a predetermined portion having assumed three-dimensional position information, (a4) calculating three-dimensional coordinate sets corresponding to the predetermined portion on a basis of the assumed three-dimensional position information, the first image, and the first camera parameter set, (a5) determining first pixel coordinate pairs and second pixel coordinate pairs corresponding to the predetermined portion in the first image and second image, respectively, on the basis of the three-dimensional coordinate sets, (a6) calculating an evaluation value on the basis of pixel values at the first pixel coordinate pairs and pixel values at the second coordinate pairs, (a7) updating the camera parameter sets on the basis of the evaluation value.
