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.

Abstract: A projection system includes an invisible light projector, an imaging unit, an image generator, and a visible light projector. The invisible light projector projects a predetermined invisible light image onto the object via invisible light. The imaging unit captures an image of the invisible light projected from the invisible light projector. The image generator measures a shape of the object based on the image captured by the imaging unit to generate image data showing image content for projection onto the object in accordance with the measured shape. The visible light projector projects the image content shown by the image data onto the object via visible light. The invisible light projector emits pulsed invisible light to project the measurement pattern. The image generator generates the image data based on an image captured in accordance with a timing for the pulsed light emission.

Abstract: A projector system including a projector unit and a control device. The projector unit includes: a projector; a change mechanism that changes a projection direction; a plurality of optical systems having different optical properties; and a switch mechanism that selects one of the optical systems. The control device includes: a change unit that controls the change mechanism; and a switch unit that causes the switch mechanism to place one of the optical systems to be used for the projector in conjunction with the changing of the projection direction of the projector which is caused by the change unit.

Abstract: A projection system includes an invisible light projector, a background member, an imaging unit, an image generator, and a visible light projector. The invisible light projector projects a predetermined invisible light image onto the object via invisible light. The background member is disposed behind the object in a direction of the invisible light emitted from the invisible light projector. The imaging unit captures an image of the invisible light projected from the invisible light projector. The image generator measures a shape of the object based on the image captured by the imaging unit to generate image data showing image content for projection onto the object in accordance with the measured shape. The visible light projector projects the image content shown by the image data onto the object via visible light. The background member has a light shielding surface that does not diffusely reflect the invisible light incident thereon.

Abstract: A projector according to the present disclosure includes: a projection unit, a lens unit, an imaging unit, and a computing unit. The projection unit displays a first image. The lens unit projects the first image that is displayed by the projection unit. The imaging unit images a second image, which is projected by another projector, through the lens unit. The computing unit computes a distance between a surface on which the second image is projected and the another projector. Such the distance is computed from imaging data of the second image imaged by the imaging unit, and from spacing information on a spacing between the projector concerned and the another projector.
