摘要
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.
