Description

Technical field

The invention relates to the field of entertainment and educational complexes using virtual reality and can be used in the field of entertainment, education and culture, for example, in advertising, presentation, entertainment or educational equipment, as part of exhibition stands, means of informing the public and other similar means.

State of the art

The prior art device is disclosed in the patent for invention EP 2335117, published 06/22/2011, which implements the method of creating the Ghost Pepper. This device contains a reflective and transparent screen to create a virtual image. The device is equipped with a rear projection screen, changing the distance between which and the projector allows you to create the illusion of moving a virtual image.

In addition, a prior art device for presenting moving images against a scene is disclosed in US Pat. No. 5,865,519 published on 02/02/1999, which is closest to the claimed invention, which includes an image source, transparent smooth foil and a rear projection screen made with the possibility of vertical movement. When you change the position of the back projection screen, the virtual image changes its position relative to the viewer.

The disadvantage of the above devices is that in the known technical solutions it is impossible to obtain a movable virtual image focused at any moment of its movement, due to a change in the distance between the image source and the rear projection screen.

Disclosure of Invention

The technical result, to which the claimed invention is directed, is to provide dynamic changes in the perspective of a virtual image without loss of image quality and without the need to control the focus of the image source while providing the possibility of realizing the effect of dynamic image rotation.

The specified technical result is achieved due to the fact that in the device for presenting moving images containing an image source and a transparent reflective screen, the image source is an LCD or OLED monitor, which is located on a dynamic platform made with the possibility of vertical and horizontal movement, and the monitor is installed on the platform with the possibility of rotation around an axis perpendicular to the monitor screen.

In this case, the transparent reflective screen can be installed at an angle, preferably 45 °, with respect to the image source. As a transparent reflective screen, a translucent mirror or a similar film mounted on the frame can be used. The size of the transparent reflective screen can be 3500 by 6000 mm or 4000 by 8000 mm. The size of the area in which the monitor is moving can be 6,000 by 6,000 by 3,000 mm or more.

The rotation of the monitors can be carried out both 360 ° degrees, and 180 ° and 90 °. In the last two cases, it is advisable to use limiters that prevent the monitors from rotating beyond the specified ranges.

Projecting an image from an image source made in the form of a monitor directly onto a transparent reflective screen allows you to receive a formed image at any time when you move the image source right - left and / or up - down, which allows you to dynamically change the perspective of a virtual image without losing quality image and without the need to control the focus of the image source. The rotation of the monitor around an axis perpendicular to its screen implements the effect of dynamic rotation of the image. The combination of dynamic changes in the perspective of the image and its rotation allows you to implement a new type of visual effects.

The generated image, depending on the degree of reflection / transmission of the mirrors, the angle of their inclination, can relate to the field of two-dimensional 2D, three-dimensional 3D (built on the principle of the Pepper's ghost illusion) and transitional type of images.

Brief Description of the Drawings

The invention is illustrated by drawings, where:

in FIG. 1 shows a diagram of a device with a horizontal dynamic platform;

in FIG. 2 shows a diagram of a device with a vertical dynamic platform.

Embodiments of the invention

A device for presenting moving images contains an image source 1 and a transparent reflective screen 2. Image source 1 is a monitor, which can be used as any monitor, such as OLED, LED, LCD, LCD with any resolution from HD and higher, including including full-HD 4k, 8k and similar displays.

The image source 1 is made to rotate around an axis perpendicular to the monitor screen and is located on the dynamic platform 3. The transparent reflective screen 2 is installed at an angle, mainly 45 °, with respect to the image source 1. Dynamic platform 3 is made with the possibility of vertical (up - down) and bilateral horizontal (right - left) movement.

The dynamic platform 3 can be positioned horizontally, as shown in FIG. 1, or vertically, as shown in FIG. 2. In the first case, the dynamic platform is parallel to the floor 4, on which seats for spectators 5 are placed, in the second case, perpendicularly.

To create a variable perspective of the virtual image, the dynamic platform 3 moves up - down and / or right - left and, accordingly, the image source 1 moves. As a result, the light forming the imaginary image from the image source 1 falls on a transparent reflective screen 2 and partially reflects from him. At the same time, part of the light forming the imaginary image from the image source 1 partially passes through the screen 2. The viewer located on the side of light reflection from the image source 1 will see the imaginary image generated by this source. In this case, the imaginary image will be behind the screen 2 and, depending on the trajectory of the dynamic platform 3, the imaginary image will accordingly move and / or rotate. Moreover, at every moment of the movement of the imaginary image, it will be in focus for the audience.
