Description

Large stereoscopic imaging device

technical field

The utility model relates to a three-dimensional image imaging device, in particular to a large-scale three-dimensional image imaging device, which enables viewers to watch a three-dimensional image floating in the air from any angle of 360 degrees. the

Background technique

Binocular vision is to observe the same object from two visual angles (ie, the left eye and the right eye) at the same time. Because the positions of the left eye and the right eye are different, there are subtle differences in the scenes observed by each, and this difference produces a three-dimensional effect. root cause. the

The so-called "visual persistence" means that the eyes will temporarily retain the image we see. After removing the object in front of us, we can still see the afterimage. This situation is called "visual persistence"; For example, it is the use of "visual persistence"; when you draw pictures of continuous actions on a stack of paper one by one according to the action sequence of the characters, because of the visual persistence, before the original image has completely disappeared , another picture will be reflected in the eyes immediately, and at this time the eyes will have the illusion that "the still image is moving on the paper". It feels smoother and more real when you wake up. the

The screens of TV and movies are also made using the same principle, except that the screens of general cartoon movies are about 15 to 20 frames per second, while movies and TVs are played at 24 to 30 frames per second. the

Although the imaging principle of stereoscopic images has been developed for a long time, its stereoscopic effect is not good, and the bottleneck of imaging technology of stereoscopic images has been unable to break through; moreover, the known technology utilizes the difference of spectral wavelengths to generate The grid covers the time difference between the left eye and the right eye, causing the illusion of a three-dimensional image, and it is necessary to wear three-dimensional glasses to have a three-dimensional effect, and the practicability is greatly reduced; in view of the defects of the known products that still need to be overcome, the utility model The inventor of the company had a creative idea, combined with his accumulated professional knowledge and practical design experience in related industries, and devoted himself to research, and finally designed a three-dimensional imaging device. the

Utility model content

The purpose of the utility model is to provide a large-scale stereo image imaging device, which enables viewers to watch the stereo images floating in the air from any angle of 360 degrees. the

In order to achieve the above object, the utility model provides a large-scale stereoscopic image imaging device, including: four projectors, four optical mirrors, four transparent mirrors, a supporting box seat and four image source optical mirrors, wherein: Four projectors are respectively placed on the top edge of the east, west, south, and north directions to provide image playback sources. The projectors are connected to the power line at the rear end of the bottom edge to provide power; four optical mirrors, The four projectors are arranged obliquely through the fixing rods; four transparent reflective lenses are attached with a see-through reflective film on the outer surface, and the four transparent reflective lenses are combined into an inverted quadrangular pyramid shape and fixed on the The bottom of the four projectors is supported and fixed by the support box seat, and the four transparent reflective lenses are respectively set at an angle of 45 degrees to the ground; the four image source optical reflectors correspond to the four transparent reflective lenses respectively, and are placed on the ground so It is combined into an overall structure. the

Due to the adoption of the above technical solutions, the utility model projects the image on the optical reflector through the projector, and then reflects the image on the image source optical reflector, so that the image source optical reflector has an image source pattern, and the four image source patterns are projected again. Based on the four transparent reflective lenses in the shape of an inverted pyramid, the four image source patterns are combined in the center of the four transparent reflective lenses, so that viewers can watch the three-dimensional images floating in the air from any angle of 360 degrees, achieving It can also present a lifelike three-dimensional sense, and increase the practical value of the product with innovative design. the

Detailed ways

In order to achieve the above purpose, and to enable examiners to have a further understanding of the advantages, purpose and efficacy of the utility model, the utility model will be described in detail below with the accompanying drawings. the

First of all, please refer to Figs. 1 to 3, the utility model large stereoscopic image imaging device includes: projector 10, optical reflector 2, transparent reflector 3, support box seat 4 and image source optical reflector 5, wherein :

Four projectors 10 are placed on the top edge respectively in the four orientations of east, west, south and north to provide image playback sources. The projectors 10 are connected to the power cord 11 at the rear end of the bottom edge to provide power. the
