Projector, mapping data creation method, program, and projection mapping system

摘要

Mapping data capable of creating a projection mapping image that matches the outer shape of each surface of a three-dimensional object is generated. The projector has a mapping data generation unit (403) that generates mapping data in response to a data creation request. The mapping data generation unit three-dimensionally measures a three-dimensional object, and outputs three-dimensional position data in which the position and shape of each surface on which an image on the three-dimensional object is projected are represented by three-dimensional coordinates (a three-dimensional sensor unit ( 405) and the coordinate system of the three-dimensional position data is converted into a projector coordinate system in which the projection area of the image is represented by three-dimensional coordinates with the point where the principal rays from the pixels located diagonally on the image forming surface intersect as the origin. And a coordinate conversion unit (406) that performs coordinate conversion, and based on the coordinate-converted three-dimensional position data, obtains the position of each surface of the three-dimensional object and the ridge line indicating the outer shape of each surface, and generates data for mapping. A part (407).
