Information generation method using projection image and taken image, information generation system, and non-transitory computer-readable storage medium storing program

Abstract

An information generation method including identifying a correspondence relationship between a projector coordinate system and a camera coordinate system, the correspondence relationship identified based on a first image and a second image, the first image projected on a projection target from a projector, and the second image obtained by imaging the projection target using a camera in a state in which the first image is projected on the projection target, displaying, by a display device, a taken image of the projection target which is taken by the camera, receiving a first operation which designates a display area in the camera coordinate system, and generating information for making the projector project a projection image in which a projection object is disposed in the display area designated by the first operation based on the correspondence relationship and information which representing the display area designated by the first operation.
