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 8):
A camera calibration device, comprising:\n a calibration image capturing circuitry, which includes first and second cameras of different types, which are configured to capture first and second calibration images, respectively, through use of the camera calibration board of  claim 1 ; first and second feature point detection circuitry, which are configured to calculate first and second feature points from the first and the second calibration images, respectively; first and second camera parameter estimation circuitry, which are configured to calculate first and second camera parameters for the first and the second cameras from the first and the second feature points, respectively; and a bundle adjustment circuitry, which is configured to calculate extrinsic parameters between the first and the second cameras through use of the first and the second camera parameters.
