Abstract
An information processing apparatus performs coordinate calibration between a two-dimensional (2D) coordinate system and a three-dimensional (3D) coordinate system. The apparatus includes a 2D camera interface, a 3D camera interface, and a processor. The processor is configured to receive, from the 2D camera interface, first 2D image data of a flat plate at a first position and second 2D image data of the flat plate at a second position different from the first position, receive, from the 3D camera interface, first 3D coordinate information of the flat plate at the first position and second 3D coordinate information of the flat plate at the second position, and generate a transformation matrix for transforming a 3D coordinate value to a 2D coordinate value, based on the first and second 2D image data and the first and second 3D coordinate information.
