Omnibearing stereo virtual image forming apparatus

Abstract

The invention discloses an omnibearing imaging device of stereo virtual images, comprising an imaging apparatus for providing real image sources, and a frame for mounting reflection films with a certain inclined angle, wherein, the reflection films formed by achromatous transparent medium are partly transparent and partly reflective in optical characteristic, and are inclinedly arranged on the optical path of the imaging apparatus, and the frame is in a multi-pyramidal shape and used for mounting the plurality of reflection films with a same inclined angle in multi-direction. The imaging apparatus can be a plurality of projectors, panel display devices, CRTs or lamp boxes, which are arranged at positions corresponding to the plurality of reflection films. The device of the invention adopts the frame with a special structure and a special shape, the plurality of reflection films are inclinedly mounted in multi-direction to be matched with the plurality of real image sources corresponding to the positions of the reflection films, thereby obtaining stereo virtual images with strong stereo performance and visibility in multi-direction. In this way, the device according to the invention has vivid visual effect, and can be widely used in the fields of advertisement, exhibition, performance, conference, etc.

Description

technical field [0001] The invention relates to the field of reflectors for projecting light beams, in particular to an imaging device for projecting images onto an inclined and partially reflecting screen to obtain a three-dimensional virtual image with a sense of depth through the screen. Background technique [0002] In the application fields such as advertising, display, performing arts, conference, publicity, etc., imaging equipment needs to be used frequently. In the past, equipment such as slides or projectors was mainly used to obtain two-dimensional direct imaging. Although the above-mentioned technologies are widely used, they have obvious defects. The second is that when the reporter intervenes between the slide as the image source or the projector and the imaging screen, it will block a part of the light, so that the image cannot be projected on the screen in this area and form a black shadow. [0003] In the prior art, there is also a type of imaging device uti...

Problems solved by technology

[0007] In addition, although the tension of the screen in the prior art can be adjusted to a certain extent, the degree of slack of the screen in the actual implementation has subtle differences depending on factors such as the use time and screen size. In the adjustment structure of the prior art, due to tension The belt has flexible characteristics, and it is difficult to achieve the desired effect with a small amount of adjustment of the screen tension, and the degree of retention after adjustment is also poor

The final consequence is that the obtained virtual image is distorted due to the difficulty in maintaining the flatness of the screen
