Embodiment Construction

[0030] figure 1 An arrangement of a projector, screen and tools for entering information about an image on a screen into a computer is shown. The device comprises a computer (1) with installed software, and a camera (2) and projector (3) connected to the computer (1). The device also includes a screen (4) having a curved (ie spherical) surface for displaying video content. The PC includes a video input (6) for capturing source video. The remote control unit (5) is connected to the PC through the radio module (7) to manage the software modules.

[0031] figure 2 An approximate arrangement of four projectors for projection onto a spherical screen is shown.

[0032] As an example, consider the functionality of the device to which projectors 31, 32, 33, and 34 are connected. Each projector forms its own image segment 31', 32', 33' and 34' on the screen (4) superimposed with the other projectors 31-34. Together these projectors cover the entire surface of the screen 4 .

Abstract

The group of inventions relates to forming and displaying an image on curved screens using projectors, and is applicable in domed multiple projection systems, full dome theatres, planetariums, different simulators and virtual reality. The claimed device comprises a server, a camera, a module for remote control and switching. A plurality of projectors can be connected to a single server with the aid of image separating devices. The inventions make it possible to combine several information display devices to produce a single synchronized image while preventing visible overlaps, differences in colour and light intensity or parasitic flares between fragments generated by different projectors or digital screens. The inventions also provide: the possibility of playing back a high resolution encoded video stream and a multichannel audio stream; the possibility of capturing and displaying high-resolution audio and video in real-time by working with licenses which allow playback of an encodedvideo stream.

Description

technical field [0001] The present invention relates to generating and displaying images on a screen using a projector. It can be used in dome projection systems, simulators and virtual reality systems. Background technique [0002] The prior art discloses the following technical solutions. [0003] The prior art discloses a camera-based auto-calibration system for multi-projector systems that compensates for geometric distortions on the curved surface of the screen, color gamut differences, and black-and-white balance in overlay regions (Accessed Oct. 23, 2014. US Patent Application No. 2014313423). [0004] The prior art discloses a multimedia content encryption method (Taiwan Patent No. 201448577 dated December 16, 2014), in which a random segment of the content is selected and encrypted, and a key for the segment is generated. A license file is created based on the identification information of the files of the fragments. [0005] The prior art also discloses a conte...
