Abstract:
A camera calibration board, which is arranged three-dimensionally above a board, includes the board, a plurality of flat plates, and a plurality of support columns having the same length. The plurality of flat plates are spatially arranged in a plane different from a plane in which the board is arranged. The board and each of the plurality of flat plates have different reflectances with respect to visible light. With this configuration, it is possible to accurately measure extrinsic parameters between cameras, which are required for calibrating cameras that use different types of image sensors, in order to easily analyze a group of images acquired from a plurality of sensors.

Claim (Index 13):
A camera calibration program recording medium having recorded thereon a camera calibration program for causing a computer to execute the procedures of:\n calculating first through M-th feature points from first through M-th calibration images, respectively, where M is an integer of 2 or more, which are captured by first through M-th cameras of different types, respectively, through use of the camera calibration board of  claim 1 ; calculating first through M-th camera parameters for the first through the M-th cameras from the first through the M-th feature points, respectively; and calculating extrinsic parameters between the first through the M-th cameras through use of the first through the M-th camera parameters.
