  • Patent number: 9894330
    Abstract: An information processing apparatus includes an obtaining unit, a setting unit, and a correction unit. The obtaining unit obtains a first image including a first overlap area having a first end side portion and a second image including a second overlap area having a second end side portion. The setting unit sets a first reference line that forms a first division area in the first overlap area and a second reference line that forms a second division area in the second overlap area. The correction unit executes corrections for the first overlap area, the first division area, and the second division area with the first reference line, the first end side portion, and the second end side portion respectively, the corrections being based on shapes of the first and second overlap areas and based on projection of the first image and the second image.

  • Patent number: 9894332
    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.

  • Patent number: 9841847
    Abstract: A projection device according to the present disclosure includes a sensor unit (for example, a camera), a detection unit, a controller and a projection unit. The sensor unit detects an object. The detection unit detects a moving object (for example, a person), a first object, and a second object based on a signal output from the sensor unit. The controller generates a projection image such that a first image corresponding to the first object is projected on a first projection region and a second image corresponding to the second object is projected on a second projection region. In this case, the first image is determined based on a position of the moving object, and the second image is determined without depending on a position of the moving object. The projection unit projects the projection image.
