Camera calibration device and camera calibration method

Abstract

One objective of the invention is to simplify a calibration correction operation. According to the present invention, a camera calibration apparatus, which obtains camera parameters based on a correlation between world coordinates, in real space, and image coordinates, in an image recorded by a camera, includes: a calibration unit A113, for obtaining camera parameters by employing a set of coordinates for an index point, for which a coordinate value on the world coordinates is previously known, and a corresponding point on the image coordinates, which is correlated with the index point; a calibration correction unit A114, for detecting a correlation error for a correlation between the world coordinate value of the index point and an image coordinate value of the corresponding point; and a display controller A112, for displaying the detected correlation error on an image display device, by correlating the index point with the corresponding point.
