Abstract
A position specifying method includes generating relation information based on first coordinates and second coordinates, the first coordinates indicating coordinates of a portion of a target object in three dimensions, at which a specific point is located, in a state where a projector projects the projection image having the specific point onto the target object, the second coordinates indicating coordinates of the specific point in the projection image in two dimensions, the relation information indicating a correspondence between a three-dimensional coordinate system and a projector coordinate system, the three dimensional coordinate system being used by a measuring instrument that specifies the first coordinates, the projector coordinate system defining the second coordinates and coordinates of the projector, and specifying a position of the projector in the three-dimensional coordinate system based on the coordinates of the projector, by using the relation information.
