Abstract
A plurality of cameras acquire images of a plurality of reference points located on known positions in a three-dimensional space, an image processor obtains the coordinates of projected points thereof on the respective images, and a plurality of affine cameras having linear relation between the three-dimensional space and images are assumed for calculating how the affine cameras project the respective reference points and correcting the coordinates of the projected points to be consistent with the projected points.
