Camera calibration board, camera calibration device, camera calibration method, and camera calibration program recording medium

摘要

The camera calibration board three-dimensionally arranged on the base includes a base and a plurality of support columns having the same length as the plurality of flat plates. The plurality of flat plates are arranged on different planes in the space with respect to the base. Each of the substrate and the plurality of flat plates has a different reflectance for visible light. This makes it possible to accurately measure external parameters between cameras, which are necessary for calibration between cameras using different types of image sensors, in order to easily analyze image groups acquired from multiple sensors.
