Abstract
To make it possible to associate a world coordinate with a coordinate of an imaging device without using a calibration board. A plurality of pattern images are generated by receiving measurement pattern light reflected from a measuring object. X coordinate, Y coordinate, and Z coordinate of a specific point are measured based on a plurality of pattern images, and a calibration target is generated from measurement result of the X coordinate, Y coordinate, and Z coordinate. Calibration is executed using the generated calibration target.
