A projection screen for forming an image by converting light pixel pulses from a digital projector comprises a three-dimensional sheet matrix made of a transparent composite. Functional inclusions for light-scattering, light-absorbing and luminescence of the light from the projector are distributed through the matrix thickness to thereby enable that the conversion of the light pulses into the image for direct perception by eyesight be performed throughout the volume of the matrix. The matrix thickness between the frontal and rear surfaces of the matrix is selected for digital image sources between an inter-pixel grid width and tenfold diagonal size of a pixel of a digitized image on the screen. The object of the invention is to reproduce identifying features of informational models of real objects in a wide angle of image perception under side lighting.

A projection system includes a plurality of projection devices configured to perform position measurement and projection on a target object. Each of the projection devices includes: an invisible light projection unit configured to project invisible measurement light onto the target object; a light receiving unit configured to receive reflection light of the measurement light, the reflection light being reflected from the target object; a computing unit configured to calculate position information of the target object on the basis of the reflection light of the measurement light; and a visible light projection unit configured to project a visible light video content on the basis of the position information of the target object. A first projection device and a second projection device of the plurality of projection devices project the measurement light at different projection timings.

Systems, methods and apparatus to continuously calibrate images displayed on a screen or surface by one or more projection devices during display of the images are disclosed. The systems, methods and apparatus comprise defining a plurality of fiducial markers on the screen, detecting, by a registration device, such as a camera, the plurality of fiducial markers in an image of the screen, adding a plurality of reference markers to an image displayed on the screen, detecting, by the registration device, the plurality of reference markers in the displayed image, determining a mapping between positions of the reference markers on the screen to positions of the reference markers in the displayed images, calculating an image warp based on the mapping and a layout of the images to be displayed and applying the image warp to images from an image generator to produce geometrically corrected images for display on the screen.

A projection apparatus including a housing and a first projection module is provided. The housing includes a curved projection area and an opening, wherein the curved projection area includes an inner surface and an outer surface opposite to each other. The first projection module is detachably disposed in the housing through the opening and corresponds to the curved projection area, wherein the first projection module projects an image onto the inner surface of the curved projection area, such that the outer surface of the curved projection area displays the projected image. The projection apparatus provided by the invention has the curved projection area to dynamically display a stereo image.

The present invention relates to display systems that use materials made from various arrangements of lenses and other optical materials. Careful design and use of these materials can be used to achieve display systems with many desirable visual effects having applicability in image and video displays, virtual reality, immersive environments, as well as in architecture, art, entertainment, and interactive systems.

The disclosure provides a projection system and a projection operation method. The projection operation method causes the projection device disposed inside the biologically-modeled housing to project the facial image onto the face projection area of the biologically-modeled housing. The face projection area is light-transmissive and curved. The controller identifies the voice signal received by the sound-receiving device. When the controller obtains the identification result, if the projection data stored in the storage device includes the target projection data corresponding to the identification result, the controller controls the projection device to project the facial image according to the target projection data, or, if the projection data stored in the storage device does not include the target projection data, the controller controls the communication device to receive the target projection data from the external device and stores it in the storage device.
