Abstract
A projection system projects an image corresponding to a shape of an object. The projection system includes a non-visible light projection unit, an imager, an image generation unit, and a visible-light projection unit. The non-visible light projection unit projects a predetermined non-visible light image with non-visible light having predetermined polarized light as a main component, onto the object and a background member that reflects the non-visible light while the background member maintains the predetermined polarized light. The imager images a non-visible light image reflected by the object and the background member while blocking the non-visible light of the predetermined polarized light, and generates imaged data. The image generation unit measures the shape of the object based on the imaged data, and generates image data according to a measurement result. The visible-light projection unit projects an image shown by the image data, onto the object with visible light.
