Abstract
An image projection system includes an infrared ray projection apparatus that projects a pattern image for shape measurement toward a projection target, an imaging device that captures the pattern image, a calculation device that acquires three-dimensional shape information of the projection target based on the captured pattern image and converts a content image into a projection content image corresponding to the projection target based on the three-dimensional shape information, and a visible light projection apparatus that is disposed in a different position from the infrared ray projection apparatus and projects the projection content image toward the projection target, in which the calculation device, based on images of a visible light image projected by the visible light projection apparatus and a non-visible light image projected by the infrared ray projection apparatus, executes processing of associating each pixel of the non-visible light image with each pixel of the visible light image.
